Use this savings calculator to estimate how a starting balance and regular monthly deposits could build toward a savings goal over time.
You can include an estimated annual percentage yield, or use 0% if you want to see how the plan works using contributions alone.
What This Savings Calculator Helps You Check
This tool is designed around a practical question: “If I keep saving this amount, where could I be by my target date?”
It separates the money you contribute from the estimated interest earned so you can see whether progress is mainly coming from your deposits or from account growth.
You can also enter an optional savings goal to see whether the current plan is projected to reach it.

Monthly contributions are modeled at the end of each month. The projection assumes the same APY and monthly contribution throughout the entire period.
How the Projection Works
The calculator converts the annual percentage yield you enter into an equivalent monthly growth rate.
Each simulated month, the existing balance grows first and the monthly contribution is then added at the end of the month.
If you enter 0% APY, the result will simply equal your starting savings plus your monthly deposits.
APY Does Not Mean the Rate Will Stay the Same
The calculator holds the entered APY constant only so you can compare scenarios. Actual savings-account yields can change.
The estimate also assumes you do not withdraw money during the projection and that every planned contribution is made.
Taxes, account fees, minimum-balance requirements, promotional rates, and other account terms are not included.
What About Inflation?
This calculator shows future dollars and does not reduce the projected balance for inflation.
That matters more for long-term goals because the same dollar amount may buy less in the future. For shorter goals, the nominal savings target may still be the most practical number to track.
Savings and Investment Returns Are Different
This tool is intended for a savings-style projection using an entered APY. It is not designed to model uncertain investment returns, market losses, dividends, capital gains, or portfolio volatility.
For a pure compounding comparison across different contribution and compounding frequencies, use the Compound Interest Calculator instead.
