This Investing Returns Calculator is an easy and effective way to explore how your money could grow through investing. Whether you’re saving for a long-term goal, comparing potential outcomes for an ISA or SIPP, or simply curious about the power of compounding, it’s a great starting point for understanding how small, regular investments can add up over time.
What is a investment returns calculator?
The Good Money Guide Investing Returns Calculator is designed to help you estimate how much your money could grow over time through investing.
By entering a few key details such as your starting amount, how much you plan to invest regularly, your expected rate of return, and how long you’ll invest for, the calculator gives you an instant projection of your potential portfolio value.
It’s a simple way to visualise how compounding returns work and how regular investing can help you build wealth over time.
How to calculate your returns on investment?
To get started, fill in the fields provided. Begin with your initial investment, which is the lump sum you plan to invest at the start. Next, enter the expected annual return, which is the percentage growth you hope to achieve each year. Be realistic here — long-term market returns are often between 4% and 8% depending on risk and asset mix. You can then add a monthly investment amount if you intend to make regular contributions. Finally, set the duration in years to see how your investment might perform over time.
How much money can you make investing?
Once you’ve entered the information, the investing returns calculator will display three main figures: your final portfolio value, your total investments, and your total returns. The final portfolio value shows what your money could be worth at the end of the chosen period, combining your contributions and growth. The total investments figure represents how much you’ve personally paid in (your initial amount plus any monthly payments), and the total returns show how much growth your portfolio could generate over the period.
The results are best used as a guide rather than a guarantee. The calculator assumes a steady, fixed rate of return and doesn’t account for investment fees, taxes, or inflation — all of which can affect your real-world returns. For a more accurate picture, try testing a few different scenarios, such as optimistic, conservative, and middle-of-the-road return rates, to see how changes in performance could affect your outcome.
For example, if you start with £2,000, invest £100 each month, and achieve a 5% annual return over 10 years, your portfolio might grow to around £18,000. Of that, about £14,000 would be your own contributions, and roughly £4,000 would come from investment growth. This demonstrates how compounding works — your money earns returns, and then those returns go on to earn more.

Is Interactive Investor a good general investing account?
Yes, ii’s GIA won our award for best general investment account in 2023 and 2022. This is because of its excellent fixed-fee pricing, which makes it a good choice for investors with over £10,000 to invest. ii’s fixed fee keeps your total account costs low no matter how big your portfolio gets. You can also invest in a markets ranging from UK and international shares to funds, trusts, bonds and ETFs.

You pay a single extra fee of £5 a month, and their monthly cost is zero.

Is ii’s GIA Better than its ISA?
The GIA is better if you have lots of money to invest as the maximum you can put in an ISA tax-free each year is £20,000, so anything above that you should invest in a GIA. However, if you have less than £20,000 to invest each year, the ii ISA is better option as your profits will be tax free.

ii’s platform is very easy to use and it gives lots of market data on potential investments.

Lightyear Is An Easy To Use Investment App With Very low Fees
Provider: Lightyear
Verdict: Lightyear is one of the better free investing apps as they provide access to US stocks and local markets with FX fees as low as 0.35%. Lightyear is a new investment app that offers low cost investing in UK, European and US shares. The company was founded by one of the first Wise (Transferwise) employees, Martin Sokk with a similar objective of making investing as cheap and easy as possible. Capital at risk.
Lightyear is a simple and approachable way to invest in stocks and ETFs without unnecessarily large fees. A very well-designed low-cost investing app with discounted FX charges, limit and recurring orders for investing in local and international markets.
Special Offer: Sign up with a promo code GOODMONEYGUIDE deposit at least £50 and get 10 trades for free. T&Cs apply. Capital at risk.
Fees: Lightyear is very cheap for investing, there is no account fee for a general investing account and only £1 commission for buying UK shares and a max of $1 for US stocks. Lightyear make their money on the FX Fees. With Lightyear, they apply the FX fee on top of the interbank rate, so you can actually see the amount you are charged for the conversion.
When I interviewed Martin Sokk he told me Lightyear aims to expand into different countries quickly, so they can help people to invest in their local stock markets, but also in America, which is where a large percentage of people want to buy stocks.
And rightly so, US shares are all household names, and one of the key drivers for investing is to buy companies you love and use. Lightyear will make money charging 0.1% per trade (or $1 what ever is bigger) and converting GBP, HUF & Euros, etc. into USD when people buy US stocks.
FX, therefore, is a key part of Lightyear’s monetisation strategy because, if you charge very low commission and account fees you have to make money somehow. So Lightyear, aim to make it’s money in the background, initially from foreign exchange fees. FX is a very good way to make money, because, a) no-one really understands how the pricing works, and b) because you don’t see the charge, it’s built into the buy/sell spread.
You can see in the below example what the fees would be when I bought some Tesla shares testing the app.
Market Access: Lightyear has just added 1,300 new instruments, bringing the total up to almost 5,500. These include well-known UK names such as Rolls-Royce, easyJet and IAG; to defense ETFs, US stocks. This is great becuase one of my concerns about new investing apps is that they normally just cater to the most heavily traded apps. It’s great to see Lightyear providing wider market access.
Plus, they are proactive about it too. Lightyear says they have put live 98% of non-complex US instruments asked for by customers in the past 3 months.
One of the other really cool things about Lightyear is that you can listen to earnings calls directly on the app.
Multicurrency account & order types
Another point to make here is that you also get a multi-currency account, where you can hold foreign currency. The advantage of this is that you don’t need to do as many FX conversions which can help keep costs down.
Lightyear comes with features like fractional US shares, limit orders, and regular investing. You can also quickly see which shares pay the highest dividends or make the most money relative to their share price to help you pick stocks.
Progression to servicing local customers and local markets
When Lightyear first started, you could only invest in a handful of UK stocks, and they were ADRs listed in the US denominated in USD, rather than the local listings on the LSE. So, you were paying an FX fee when you really shouldn’t have to, admittedly, there is no stamp duty so technically paying 0.35% on FX rather than 0.5% to HMRC is cheaper.
Lighyear have a cash and investment ISA, but no SIPP account, but I suspect that is next on the “product roadmap”.
But anyway, they’ve sorted that now, and if you want to invest in UK shares like Lloyds, you can actually buy them on the LSE, something that eToro is yet to do. With them, you still have to buy USD-denominated shares.
I’ve mentioned how annoying that is many times and yet they continue serve themselves as a global broker instead of their customers as locals. It’s nice to see that Lightyear, fixed that problem early on.
Like Transferwise, like Lightyear
To draw on one final Transferwise comparison, it is very easy to use app-as-a-tool to help you start investing as cheaply as possible. The thing is though is that, transferring money is like car insurance. No-one really has any loyalty to their insurer, they just do it and move on. Investing is different. Investing is not like insurance, when you open an investing account, you could be using it for the next 30 years.
I think there will always be a place for traditional investment platforms because they provide excellent customer service and brand loyalty, they are mature platforms for mature investors and fees will eventually come down, as they have done in the past. Same as with Simpsons Tavern, it may not be as good for you as veganism, but if it survives, people will continue to go because they like it.
But, if low-cost investing apps are a gateway to getting more people to invest for their future, then they are the future too and will hopefully mature along with their customers, and Lightyear, in particular, is a great place to get started.

Verdict:Moneyfarm is a digital wealth manager that aims to make personal investing simple and accessible. It was launched initially in Italy in 2012 by Italian bankers Paolo Galvani and Giovanni Dapra and entered the UK in 2016 and has big-name financial backers such as Allianz Global Investors, Cabot Square Capital, United Ventures and Poste Italiane.
Yes, Moneyfarm is more of a digital wealth manager rather than a robo-advisor as the portfolios are put together by investment managers, rather than automatically. The automation, as it where, is fine-tuning your portfolio to match your risk/reward choices. As opposed to other robo advisors you can also top-up your portfolio with individual shares and ETFs.
Fees: Moneyfarm charges 0.75% to 0.6% up to £100k then 0.45% to 0.35% over £100k. Moneyfarm investing 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%.
Market Access: You can invest in 7 pre-made portfolios, but also (unlike a lot of other digital wealth managers and robo-adviors) also buy individual shares, ETFs, bonds and mutual funds online. It’s a bit of a shame you can’t buy US stocks, But Moneyfarm is best really for setting up regular investments in a GIA, ISA or SIPP, then letting them grow over time without too much tinkering and speculating on Tech stocks.
App & Platform: It’s really easy to use, plus it puts you through your paces to make sure you understand what you are investing in. Apparently, my Moneyfarm investor profile is “pioneering”, which means I want to take on more risk for potentially better returns.
Customer Service: This is mostly online as you’d expect but solves all issues – I’ve had some good calls with MOneyfarm about how their producsts work over the years and they really know their stuff. If you want to find out more about their ethos, you can read my interview with the CEO Giovanni Daprà on how they are so much more than a robo-advisor.
Research & Analysis: Not much to speak of other than a few guides, but that’s ok, as I don’t really want Moneyfarm spamming me with stock trading ideas.

Yes, AJ Bell’s GIA is one of the safest and cheapest ways to invest – outside your tax-free allowances in SIPPs & ISAs – for longer-term investors in the UK.

Hargreaves Lansdown General Investment Account: Excellent All-Rounder
Account: Hargreaves Lansdown General Investment Account
Description:Hargreaves Lansdown (HL) has plenty of account types including a GIA and several types of ISA, plus an excellent research portal. There's access to thousands of UK and international shares, funds, ETFs, investment trusts and corporate bonds. Capital is at risk. Capital at risk
HL is good for investors looking for more than just somewhere to buy and sell shares. The platform offers the most account types of all the investment platforms we compare, including a GIA, stocks and shares ISAs, lifetime ISAs, and junior ISAs. Plus, it has one of the best research portals to help you choose your own investments. And it boasts some of the widest market coverage, including thousands of UK and international shares, over 3,000 funds, ETFs, investment trusts, and corporate bonds.
Fees
There is no account charge for shares in a GIA with HL. Funds are charged at 0.45% for the first £250,000. There’s 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.
Is HL’s GIA Better than its ISA?
It makes sense to open a GIA only after you have exhausted your ISA allowance. With the GIA from HL, you can invest as much as you like but with an ISA you’re limited to £20,000 a year in the tax-free wrapper.
What is HL’s Platform Like to Use?

Saxo General Investment Account Review: Superb DMA Access & Service
Account: Saxo General Investment Account
Description: Saxo’s GIA is one of the most advanced accounts for UK long-term investors with access to more than 50 stock exchanges around the world and 22,000 instruments available to invest in. Saxo’s forte is as a trading platform for professional and institutional short and medium-term speculators as it offers direct market access and very low commissions. A good choice for large, active investors. Capital at risk
As well as being one of the best trading platforms, Saxo has good accounts for long-term investments. The platform has recently introduced mutual funds for investors who want to quickly build a diversified portfolio. And income investors can access a huge range of retail and institutional-grade bonds.
On balance, though, I’d say that Saxo remains more of a trading platform than an investing account. So if you’re primarily a high-risk trader and you want to incorporate some longer-term “safer” investments into your portfolio, Saxo is a good place to invest alongside your shorter-term speculation. Saxo is also one of the best brokers for earning interest on your uninvested cash.
Compared with other retail investing accounts like eToro, Saxo is a much better option because of market range, customer service and tax-free products like ISAs and SIPPs.
Fees
Saxo charges €10 a month or 0.12% a year (whichever is higher) based on the value of your portfolio. If you have a VIP account this fee drops to 0.08%. Dealing charges, which are a percentage of transaction size, are competitive – and UK shares trading commission starts at 0.1% (£100 if you buy £100,000 worth of stock) and drops to 0.05% for more active traders.
Special Offers
Platinum. If you have £200,000 or more on account, you can apply for 30% lower transaction and account costs.
VIP. For accounts with portfolios over £1m, you get even better pricing, direct connection to experts, 1:1 SaxoStrats access and event invitations.
What is Saxo’s Platform Like to Use?
Saxo’s investment platform provides exceptional access to the global markets.
Description: Dodl is a low-cost investment app provided by AJ Bell. The app fees are lower than AJ Bells, and they cater to newer investors by offering commission-free investing in AJ Bell funds, themed investments and a small selection of main market shares.
Capital at risk.
AJ Bell Dodl is a great way for the next generation of investors to invest with a “low-cost, little effort” app which focuses on making investing easy. Which it does well, Dodl is very user-friendly, has great educational content and is one of the cheapest ways to start investing.
Verdict: The GIA from CMC Invest lets you invest in major UK shares, US stocks and ETFs without having to pay commission when you deal. The app is free to use when investing in a general investment account with the Core plan. But you can upgrade to a Plus account which includes a flexible stocks and shares ISA, access to UK mid-cap shares and a USD wallet. There's also a Premium option that gives you access to a SIPP. CMC Invest cut the fees for Plus and Premium in 2025. Capital at risk
Is the CMC Invest General Investment Account Any Good?
If you are just starting out investing, then CMC Invest is a good general investment account (GIA) for some longer-term investments. But, if you are an established and experienced CMC Markets customer you may find the CMC Invest offering too basic. Better options for sophisticated investors would be Saxo, or Interactive Brokers.
Investments: Shares & ETFs
Minimum deposit: £0
Account types: GIA, ISA
Account charge: £0 – £10.99 per month (Premium previously £25 a month)
Dealing fee: £0
Fees: General investment accounts are commission and fee free. ISA accounts cost from £6.99 a month and are included in the Plus plan. For US shares there is a conversion fee of 0.39%-0.99% depending on your account.
Investing Platform: CMC Invest’s app gives you access to major stocks, and has a screener to help search for potential investments.
IG General Investment Account Review: Great Mix Of High & Low-Risk Investing
Account: IG General Investment Account
Description: IG is primarily a trading platform (and one of the best, at that) but also has an investment account through which you can deal in physical stocks and shares, including ETFs, in the UK, Europe, US and Asian markets. If you don't want to choose your own stocks, IG also has a managed investment product called Smart Portfolios. These are pre-made diverse portfolios with exposure to the global markets through shares, bonds, property and commodities.
IG is a good choice for traders also looking for a cost-effective way to hold long-term investments in a GIA, or a stocks and shares ISA or SIPP. Capital is at risk.
Yes, we rank IG as one of the best combined investing and trading platforms in the UK. You can invest with IG through a GIA, ISA or SIPP in either individual stocks or through pre-made Smart Portfolios. One letdown, though, is the lack of access to funds and bonds – you’ll be better served by a traditional stockbroker like Hargreaves Lansdown. And unlike some rivals, like Bestinvest, IG can’t provide advice on investments.
Fees
IG charges a flat custody fee of £24 a quarter (£96 a year) for its GIA. But if you have more than £15,000 in a Smart Portfolio managed fund, or place over three trades per quarter, that fee is waived. Standard dealing fees are £8 for UK and £10 for US shares. Smart Portfolio fees are 0.5% and capped at £250 per year. Fund management charges are 0.13% and transaction costs are 0.09%.
Special Offer: Free US stock investing. There is zero commission on US share trades and just £3 on UK share trades when you trade three or more times a month.
What is IG’s Platform Like to Use?
IG’s investment platform is the same as its trading interface so this will be familiar to its short-term speculators. The platform offers good visuals of investments, with associated news and analysis.
Pros
Low-cost investing account
UK & international shares
Pre-made portfolios
Cons
Also provides access to high-risk investment products.
