What this savings calculator does

Estimate how regular deposits and an assumed interest rate can build a savings balance over time.

How to use the calculator

Enter your current savings, planned recurring deposit, interest rate, compounding frequency and time period. Use the result to see how increasing contributions or extending the time horizon can affect the projected balance.

How the calculation works

The calculation compounds the existing balance and recurring deposits using the selected periodic rate. It assumes the rate and deposit schedule remain constant throughout the period.

What the result means

Example: saving $100 per month at an assumed 5% annual rate for 10 years produces a projected balance of roughly $15,500, depending on the compounding convention.

Important assumptions and limitations

Actual savings-account yields can change, especially with variable-rate products. Fees, taxes and changes in contribution timing can also affect the final balance.

Frequently asked questions

How are savings growth and deposits calculated?
The calculator applies the entered annual interest assumption and adds the monthly contribution at the end of each modeled month.

Is the interest rate guaranteed?
No. The rate is an assumption. Savings-account rates can change unless your account terms guarantee a fixed rate.

Does it include taxes?
No. The projection is before any tax on interest income.

What happens if I increase the monthly contribution?
The ending balance generally increases because each additional deposit has more time to earn interest.
