How It Works
Our savings calculator uses the compound interest formula to project how your money grows over time. Whether you are building an emergency fund, saving for a house deposit, or planning for retirement, here is how to get the most out of this tool.
Enter Your Details
Start by entering your current savings balance and how much you plan to contribute each month. Choose the interest rate your savings account offers — you can find this on your bank's website or use one of our example rates. Select your compounding frequency: daily compounding gives the highest returns, while annual compounding is the simplest to understand. Most UK savings accounts compound daily or monthly.
Choose Your Mode
Use Growth mode to see how your savings will grow over a set time period. Switch to Goal mode if you have a target amount in mind — we will calculate the monthly contribution needed to reach it. The Withdrawal mode shows how long your savings will last if you draw down a fixed amount each month. Rate Comparison lets you see the same savings scenario at three different interest rates side by side, helping you decide whether switching accounts is worth it.
Review and Export
After clicking Calculate, you will see your projected final balance, total contributions, and interest earned. The interactive chart shows contributions versus interest over time, and the year-by-year breakdown table provides a detailed view. When you are satisfied, export your results as a clean PDF for your records. Your inputs are automatically saved in your browser so you can pick up where you left off next time.
