Planning for retirement can feel overwhelming, but a pension calculator is one of the quickest ways to find out whether you’re on track. Whether you’re saving into a workplace pension, a personal pension or a Self-Invested Personal Pension (SIPP), our free calculator helps estimate how much your pension could be worth when you retire and whether you’ll have enough income to support your lifestyle.
How To Use Our Pension & SIPP Calculator
This guide explains what information you’ll need, how the calculator works and how to understand your results.
What does the Pension & SIPP Calculator do?
Our Pension & SIPP Calculator estimates:
How much your pension pot could be worth at retirement.
Your projected annual retirement income.
Whether you’re on track to meet your retirement goals.
How increasing contributions or retiring later could improve your retirement income.
Rather than guessing whether you’re saving enough, the calculator gives you a personalised projection based on your own circumstances.
What information do you need?
Before you start, it’s helpful to have the following details:
Your current age.
The age you’d like to retire.
The current value of your pension or SIPP.
How much you contribute each month.
How much your employer contributes (if applicable).
Your annual salary (if requested).
Any other retirement income you expect to receive.
Don’t worry if you don’t know every figure exactly. Pension calculations are estimates, so reasonable approximations are usually sufficient.
Step 1: Enter your current age
Your age is one of the biggest factors affecting your retirement savings.
The earlier you start investing, the longer your money has to benefit from compound investment growth. Even small monthly contributions made over several decades can grow into a substantial pension pot.
Step 2: Choose your retirement age
Next, enter the age you hope to retire.
This determines how many years your pension has left to grow before you start drawing an income.
Try experimenting with different retirement ages. Delaying retirement by just a few years can often make a significant difference because:
Your investments have longer to grow.
You’ll usually contribute for longer.
Your pension needs to provide income for fewer years.
Step 3: Enter your current pension value
This is the total value of all your defined contribution pensions or SIPPs.
You can usually find this on your latest pension statement or by logging into your pension provider’s online account.
If you have several pensions, you can either:
Add their values together.
Run separate calculations for each pension.
If you’ve lost track of an old pension, it’s worth finding it before calculating your retirement income, as many people have forgotten pension pots from previous employers.
Step 4: Add your monthly pension contributions
Enter how much you currently save each month.
If you’re employed, include:
Your own pension contributions.
Your employer’s contributions where possible.
If you’re using the calculator for a SIPP, simply enter your own monthly contributions.
One of the most useful features of the calculator is testing different contribution levels. Increasing monthly contributions—even by £50 or £100—can have a surprisingly large impact over several decades thanks to compound growth.
Step 5: Review your projected pension income
Once you’ve entered your information, the calculator estimates:
Your projected pension pot.
Your estimated annual retirement income.
Whether you’re likely to have enough to fund your retirement.
Remember these are forecasts rather than guarantees. Investment returns, inflation and future pension rules can all affect the final outcome.
How much income will you need?
Everyone’s retirement is different.
However, the latest Retirement Living Standards suggest that a single person currently needs approximately:
£13,900 per year for a minimum retirement lifestyle.
£32,700 per year for a moderate retirement.
£45,400 per year for a comfortable retirement.
Couples generally need higher combined incomes, although shared living costs reduce the amount needed per person. These figures provide a useful benchmark when comparing your projected retirement income.
What if you’re not on track?
If the calculator suggests you may fall short of your retirement income target, don’t panic.
There are several ways to improve your retirement prospects:
Increase your monthly pension contributions.
Make additional one-off pension payments.
Maximise employer matching contributions if available.
Consolidate old pension pots where appropriate.
Delay retirement by a few years.
Review your investment strategy.
Even relatively small increases made early can make a meaningful difference over time.
Why use a SIPP calculator?
A Self-Invested Personal Pension (SIPP) gives you greater control over how your retirement savings are invested.
If you invest through a SIPP, using a pension calculator helps answer important questions such as:
Am I saving enough?
What could my pension be worth at retirement?
How much monthly income could it provide?
What happens if I increase my contributions?
Can I afford to retire earlier?
Running different scenarios can help you make informed decisions long before retirement.
Remember: A pension calculator is only an estimate
No pension calculator can predict the future with complete accuracy.
Investment returns, inflation, tax rules and your personal circumstances may all change over time. That’s why it’s worth reviewing your pension every year and updating your calculations as your salary, savings and retirement plans evolve.
The earlier you start planning, the more options you’ll have—and the easier it is to make small changes today that could significantly improve your retirement income tomorrow.
Ready to start your pension? Choose a UK FCA-regulated pension provider
Good Money Guide’s experts have tested and reviewed the UK’s top FCA-regulated private pension providers, helping you choose with confidence.
Description:IG’s SIPP account is great for active SIPP investors & Smart portfolios and lets you invest in over 13,000 UK and US shares, funds and investment trusts. Or if you can buy into an IG Smart Portfolios are expertly managed, broadly diversified portfolios with exposure to many global markets, such as fixed income and equity, along with alternative investments like gold and property.
IG SIPP clients will be able to invest in a wide range of individual stocks, ETFs, and investment trusts, as well as placings and IPOs, through IG’s relationship with Primary Bid. IG Smart Portfolios are also available to its SIPP Customers.
To start investing in a SIPP through IG you will first need to open an IG share dealing or Smart Portfolio account, and then add a SIPP account, using the MY IG dashboard. You can then set up your SIPP with Options UK, from whom you will receive an email invite. Options UK will let IG know when the SIPP is set up and they will activate it.
A SIPP with IG costs £210 per year and dealing commission for UK shares have just been removed to £0, you can buy and sell UK and US shares for free (excluding the FX fees of 0.7%). IG Smart Portfolio fees are 0.5% – capped at £250 per year. Fund management charges are 0.13% and transaction costs are 0.09%.
Yes. Alternatively, you can transfer an existing SIPP to Options UK from any UK-registered pension scheme, or a recognised overseas pension scheme.
IG SIPP clients can invest up to £40,000 in the current tax year (under existing legislation) and they will pay zero commission on US stock trades, and just £3.0 per trade on UK trades, if, they have traded at least three times, in the previous month. Options UK charges £210.00 per annum as a SIPP management fee.
Many of IG’s competitors offer SIPP trading facilities, for example, Interactive Brokers has its own SIPP trading account, which allows investors to trade in stocks, bonds, funds and ETFs, in 150 markets, spread across 33 different countries. Interactive Brokers offers its customary low commissions to its SIPP customers.
However, its SIPP account also has some additional perks, such as interest on uninvested cash balances, fractional share trading, and a stock yield enhancement program. Under which, qualifying SIPP holders can elect to lend the shares held in their SIPP on the stock loan market, via Interactive brokers, and they will receive 50% of the fees generated by way of return.
It’s also possible to trade derivatives such as futures, options, and currencies within the Interactive Brokers SIPP.
Saxo Markets also has its own SIPP account, however, the bank does not act as a pension administrator or trustee. Rather it facilitates the trading of securities within a SIPP, that is managed and administered elsewhere.
Opening a SIPP account at Saxo is free of charge and Saxo supports two SIPP providers, to whom clients can transfer their SIPPs.
Saxo’s charging structure is tiered, so you pay a commission thats applicable to either the Classic, Platinum or VIP tiers, depending on your activity levels.
Clients in the classic tier pay 2 cents per share commission on US equity trades, and 0.10% of the consideration on UK and European equity deals. Whilst VIP clients pay 1 cent per share on US trades, and just 0.05% on UK and European equity deals.
However, not every trading platform offers SIPP trading, for example, SIPP trading is not available at eToro or CMC Markets, though the recently launched CMC Invest platform will be introducing SIPP trading in the near future.
Description:Interactive Investor offers the most investment options in the UK SIPP markets. With II you can invest more than 40,000 domestic and international shares, ETFs, bonds and over 3,000 funds (AJ Bell has 2,000 and HL offers 2,500 funds).
Is Interactive Investors' SIPP (pension) any good?
Yes, interactive investor won “Best SIPP Provider” in the 2025 Good Money Guide Awards. ii has a really good pre-selected fund section, which makes crucial SIPP asset allocation decisions much easier. It’s very low cost too, with excellent education and research, and a huge range of investments to choose from.
The key advantage of interactive investor’s SIPP is that it has a flat-fee structure. This means that annual account charges do not increase as your pension pot grows in size. This structure can help those with larger SIPP portfolios save on fees, however it can be a little expensive for small pensions if you are just starting to invest for your retirement.
For smaller pension pots, those that just want to invest in ETFs, InvestEngine offer a free SIPP, but it is limited to just UK-listed ETFs, so you can’t buy individual shares. One of the good things about ii’s SIPP is that you can buy bonds, gilts, and shares in small and large UK and international companies.
Even though ii charges £3.99 for buying funds. If you compare this to Hargreaves Lansdown, which does not charge for buying and selling funds, but HL SIPP fees are higher. If you have £100,000 in your SIPP with ii you’d pay £71.88 a year, versus HL where your fees would be £450.
So, if you have a big pension, is it worth moving it to ii? Well, yes at the moment, as interactive investor claim their SIPP pricing can give you an additional £68,467 towards your pension after 30 years compared to HL. Plus, if you transfer your SIPP to ii before 31st August, you can claim up to £2,000 in cash back.
Of course, you’ll need to add cash or start a transfer of a minimum value of £10,000 to qualify for your cashback reward. Terms apply.
Pros
Huge range of investments
£1 minimum deposit makes it easy to get started
Fixed SIPP account fee that does not increase with your investments
Description: Overall we rate Wealthify as a good managed pension as they won Best Private Pension Provider 2025 in the Good Money Guide Awards, but it is not a SIPP pension as you cannot invest in individual shares, instead you pick one of their portfolios based on how much risk you want to take, so it's more of a private managed personal pension. Wealthify is authorised and regulated by the Financial Conduct Authority and owned by Aviva. Capital at risk. Your tax treatment will depend on your individual circumstances and it may be subject to change in the future.
Wealthify won “Best Pension” in the 2025 Good Money Guide Awards as it lets you invest either in an original portfolio of investments from the UK and overseas or choose an ethical investment plan made from a blend of environmentally and socially responsible investments.
Pension Fees:Wealthify has recently cut management fees for SIPP accounts holding more than £100,000 by introducing a tiered charging structure.
Any amount above £100,000 in Wealthify Personal Pension accounts will be charged at a lower annual fee of 0.3%, putting the service in a very competitive position against other providers.
This represents a reduction on the offering’s standard annual fee of 0.6% on balances up to £100,000. Both fees are charged monthly. In real terms, that means if you have £200,000 in your Welathify pension, your fees will now be £300 a year lower
The updated pricing structure is aimed at enhancing the appeal of Wealthify’s SIPP, particularly among more affluent clients.
Wealthify chief executive Richard Ambrose said: “Too many people are unaware of what they are paying in fees. It’s our duty as pension providers to make this clear. Fees are charged as a percentage of the pension pot, so the more you put in, the more fees will eat into your retirement savings.
“Whatever stage people are at with their pensions, I hope Wealthify’s new tiering inspires them to review their fees and vote with their feet so that they aren’t paying more than they need to.”
By introducing tiered fees, Aviva-owned Wealthify’s SIPP offering comes in line with its direct digital wealth manager competitors Nutmeg and Moneyfarm, as well as other personal pension providers.
Moneyfarm for example have slightly higher tiered management fees depending on the amount of assets held in their SIPPs. Wealthify’s decision to cut its pension management fees on sums above £100,000 to 0.3% puts it in a more competitive position.
Its “Fixed Allocation” service carries a fee of 0.45% up to £100,000 and then 0.25% on further investments.
By contrast, Moneyfarm has multiple fee tiers, starting at 0.75% from £500 before falling to 0.7% on investments above £10,000, 0.65% above £20,000 and 0.6% above £50,000.
Moneyfarm’s SIPP management fees then fall to 0.45% above £100,000, 0.4% above £250,000 and 0.35% above £500,000.
It is important to note these charges concern only the management of the SIPP and do not account for other costs such as the fees of funds in which portfolios are invested or transaction fees.
Market Access: You can only invest in either an Original Plan or an Ethical Plan with Wealthify, so you can’t buy individual shares. So Wealthify’s pension is better for those who just want to invest passively without being too involved. Once you have chosen your plan, you can then decide how much risk to take on by setting your pension from cautious to adventurous. You can see the difference in how Wealthify pensions are balanced for risk below, the more risk/reward you choose, the more stocks are allocated to your portfolio.
Performance: Excluding fees, Wealthify plans have returned just over 24% since 2019, with an average return of just over 4% per year. Which, if we’re honest, is not great seeing as the S&P, the major US stock market that contains 500 of the biggest US public companies, has returned around 85%. It’s not exactly a fair comparison because Wealthify plans are diversified (as portfolios are supposed to be) across bonds and different countries.
It will certainly be interesting to see the 2026 performance update after the most recent stock market crash, where you’d expect a diversified portfolio to be more resilient than an index tracker.
Customer Service: Great support from Wealthify from an experienced team that can help with any issues either via email, chat or over the phone.
App & platform: Both are easy to use and easy to navigate.
Research & Analysis: When you are logged in, you get some brief market updates online, but that’s about it, other than the odd email, about how things like the budget may affect your investments.
Remember that past performance is not an indication of future results.
Capital at risk. Your tax treatment will depend on your individual circumstances and it may be subject to change in the future.
Description:Moneyfarm lets you invest your pension in one of seven ready-made simple and diverse portfolios with different degrees of risk and reward. Users can transfer a pension or setup a new one and Moneyfarm will manage your portfolio based on your retirement target date by reducing the risk as the time approaches. Capital at risk.
Yes, Moneyfarm’s pension account fees are scaled between 0.75% for accounts between £500 and £50,000, then above £100k are 0.45% to 0.35%. Average investment fund fees are 0.2% and the average market spread when buying and selling is 0.10%
Fees:Moneyfarm’s pension account fees are scaled between 0.75% for accounts between £500 and £50,000, then above £100k are 0.45% to 0.35%. Average investment fund fees are 0.2% and the average market spread when buying and selling is 0.10%
Description:AJ Bell offers the cheapest SIPP account when you compare them against providers that charge a percentage of your portfolio value. You can invest in a wide range of investments, including stocks in more than 20 markets, over 4,000 funds, ETFs, and bonds. Capital at risk.
AJ Bell won “best SIPP provider” in our 2023 and 2022 awards. They offer a huge range of UK and international markets to invest in (with low FX fees). AJ Bell also scored very well in our survey for customer support and has an easy-to-use and low-cost SIPP account platform.
Up to £500 cashback: Switch your SIPP to AJ Bell and they will pay up to £35 per investment and £100 in exit fees as cash back to cover your costs up to £500. £100 gift vouchers: If you refer a friend to AJ Bell that opens a GIA, LISA, ISA or SIPP with more than £10,000 (within 120 days) you both get £100 Amazon gift vouchers.
Annual account charges are 0.25% for shares (capped at £10/month) and tiered for funds (0.25% up to £250,000, 0.10% up to £500,000, and free beyond), with dealing charges of £5 for shares (£3.50 for frequent traders) and £1.50 for funds.
Pros
Low SIPP account fees of 0.25% & share dealing commission
Description: We do however, consistantly rank Hargreaves Lansdown as one of the best SIPP providers in the UK (HL won best SIPP in our 2022 Awards). The main advantage of Hargreaves Lansdown’s SIPP is that it offers access to a vast range of investments. Investors have access to domestic and international equities, over 3,000 funds, bonds, as well as plenty of research and investment tools. Customer service is also top notch, with really helpful and knowledgable staff that can provide guidence if needed. Capital at risk
Yes, Hargreaves Lansdown SIPP costs start at 0.45% of your portfolio value. The account charge for shares is capped at £200 per year. Funds are charged at 0.45% for the first £250,000, then 0.25% between £250k and £1m, then 0.1% between £1-£2m. There is no charge above £2m. There is no charge for buying funds, but shares are charged at £11.95 per deal or £5.95 if you do over 20 deals per month.
But, if you open a SIPP with HL before the 30th June with £10k or more you’ll get a discount of 40% on account fees. As HL is generally quite expensive, this is a great deal, and could save you £180 in fees. But keep in mind that when this discount ends in 2026, if you have £100,000 in your SIPP with HL it will cost £450 a year, versus £155.88 with interactive investor.
For beginners and smaller accounts Hargreaves Lansdown, is a great choice, as HL offer one of the best apps on the market and provide stock research and analysis on the most heavily traded stocks in the UK and US. Hargreaves Lansdown is also good for beginners because they are quite simple to use and have an excellent reputation for customer support from their Bristol based offices.
They may be a little more expensive that some of the other platforms, but you certainly get what you pay for.
Some SIPP accounts are better suited to beginners than others. Generally speaking, beginner investors require a SIPP that is easy to use, cost-effective, and offers access to products that are well suited to beginners such as ready-made portfolios.
So, if you are a complete beginner to SIPP investing and are not confident enough to choose what individual stocks and shares you want to own in the long term. A private pension may be more appropriate. One private pension account (which is not actually a SIPP because you can’t buy individual shares) that is well suited to beginners is Wealthify. Wealthify is a robo advisor (or digital wealth manager) that offers a managed pension product. With Wealthify, you choose an investment style based on your risk tolerance. One advantage of Wealthify is that the minimum investment is just £50. One downside, however, is that there are only a few investment options to choose from.
Pros
Widest range of shares, bonds and funds to invest in.
Get started with as little as £100 or a £25 regular investment
Share fees capped at £200
Excellent research & data to help you choose what to invest in
