Monthly Savings Calculator

Estimate how your monthly savings can grow over time based on your starting balance, monthly contribution, interest rate and savings period.

Your Details

Overview

A monthly savings calculator helps you estimate how your money could grow over time. Enter your starting balance, monthly contribution, annual interest rate and savings term to see your projected final balance, total deposits and estimated interest earned.

How it works

The calculator adds growth from your starting balance and growth from your monthly deposits. It converts the annual interest rate into a monthly rate, applies monthly compounding across the full term, and then combines the future value of your initial savings with the future value of your regular contributions. The result is an estimate of your ending balance and how much of it comes from interest.

Frequently asked questions

What does this monthly savings calculator estimate?

It estimates how much your savings could be worth at the end of a chosen period based on your starting balance, monthly deposits, interest rate and time.

Does the calculator assume monthly compounding?

Yes. It converts the annual interest rate to a monthly rate and assumes interest is compounded monthly.

Are monthly contributions added at the start or end of the month?

This version assumes contributions are made at the end of each month, which slightly affects the final result compared with beginning-of-month deposits.

Does this include taxes or account fees?

No. The estimate does not include taxes, account charges, penalties or changes in rates.

Can I use this for investment growth too?

Yes, as a simple estimate. However, investment returns are not fixed, so real results may vary more than with a standard savings account.
