Savings Goal Calculator
Estimate how long monthly saving and interest take to reach a target.
Calculations happen locally. We do not send your values to our server.
Example
Starting with 5,000 and adding 500 monthly toward 25,000 at 3% estimates how many months the goal may take.
Calculation method
Each month applies annual rate ÷ 12 to the current balance and then adds the contribution at month end until the target is reached.
Important notes
This projection assumes a constant rate and contribution and ignores taxes, fees, inflation, market risk, and contribution timing differences.
Frequently asked questions
What if I already reached the target?
The result is zero months and shows the existing starting balance.
Is the result a guaranteed savings date?
No. Real returns, fees, deposits, and withdrawals can change the outcome.
