About the Savings Plan Calculator

This calculator works out how long it will take to reach a specific savings target by simulating monthly growth of your balance, combining compound interest with your ongoing monthly contribution.

Formula: Each month, Balance = Balance × (1 + Monthly Rate) + Monthly Contribution, repeated until the balance reaches the goal.

Because interest compounds on a growing balance, reaching a goal often takes noticeably less time than a simple division of the shortfall by your monthly contribution would suggest.
