Understanding Your ISA Growth
An Individual Savings Account (ISA) is a powerful tool for UK savers, allowing your money to grow without you having to pay any tax on the interest or investment returns. This calculator demonstrates the principle of compound growth, where the interest you earn also starts earning interest, leading to exponential growth over time.
The projection assumes a constant annual interest rate and regular monthly contributions. In reality, interest rates can fluctuate, and if you have a Stocks and Shares ISA, the value of your investments can go down as well as up.
Official Guidance
For the most accurate and official information on ISAs, including the latest allowance limits and rules, it is always best to consult the UK government's official resources.
