Capital at risk
Please do remember that as with all investments, your capital is at risk. Past Performance is not an indication of future performance.
How to calculate compound interest?
Our compound interest calculator requires just four key inputs from investors:
- The initial deposit represents your starting capital
- The monthly contribution shows how regular additions boost your investment growth
- The time frame determines how long compound interest or growth works in your favour
- The interest or growth rate reflects your expected annual returns
The compound interest formula used is: A = P(1 + r/n)^(nt)
- A is the final amount
- P is the principal (initial amount)
- r is the annual interest or growth rate
- n is the compounding frequency (number of times interest is compounded per year)
- t is the time in years that the money is invested
It is also important to note that the final amount displayed from the compound interest calculator depends on several factors. These include the assumptions that contributions remain constant, interest or growth rates stay unchanged, and no withdrawals are made during the investment period. Market conditions, fees, and other factors may also affect actual returns.
How much could my savings be worth?
For illustration purposes only, assuming annual compound interest, ignoring inflation. Forecast is not an indicator of future growth, which depends on the performance of chosen investments. Capital is at risk and past performance is not a reliable indicator of the future.

The power of compound interest in long-term saving and investments
The true power of using our compound interest calculator becomes evident through long-term planning, investing, and strategic decision-making.
By starting early, you can give the power of compounding more time to significantly impact your wealth, with even small initial investments potentially growing into substantial sums over decades. Making regular contributions can amplify this effect, as each new deposit of capital immediately begins earning compound interest.
The frequency of contributions also matters, since interest compounded daily grows faster than interest compounded annually. To maximise compound interest benefits, consider making regular contributions and resist the temptation to withdraw funds early.
Also, you can choose appropriate investment vehicles that offer competitive returns whilst aligning with your risk tolerance and time horizon. For example, our Individual Savings Account (ISA) allows you to take advantage of tax-efficient investing while harnessing the power of compound interest for your long-term financial goals.
