How it works
The balance grows by compounding: each month the existing balance earns a share of the annual return, and the new contribution is added. End balance equals the starting amount grown over time plus the future value of all contributions. Total return is the end balance minus everything you contributed.
How to use the Investment Calculator
Enter the values requested by the tool and start with one realistic example. Read the result together with its unit or label, then change one input at a time if you want to compare options. Keeping a note of the original figures makes the calculation easier to check later.
Use the result as a planning estimate rather than a quote or guarantee. Rates, fees, tax rules and personal circumstances can change the final figure.
