See how an opening balance, monthly savings and an interest rate can grow over time, with a chart and a year-by-year table.

01 / YOUR ASSUMPTIONS

Shape a scenario.

The model compounds monthly and adds your savings at the end of each month, matching the original calculator.

Every year, clearly.

The table contains the same values as the chart and stays readable without JavaScript chart support.

HOW THE MODEL WORKS

A transparent calculation.

For each month, interest is calculated on the current balance at one twelfth of the annual rate. The monthly savings amount is then added at month end. The chart stacks invested capital and cumulative interest so the total matches the closing balance.

This is an illustrative projection. Bank products may use different compounding schedules, fees, taxes, and rates.
