Calculate how many months it will take to reach your savings goal based on monthly deposits, interest and current savings.
How is the time to reach a savings goal calculated?
The calculator solves the future-value formula for regular monthly deposits: FV = P·((1+r)n − 1)/r, where P is the monthly deposit, r the monthly rate and n the number of months. Given your target, it finds n — the months required.
What affects the time to goal?
Monthly deposit size — the dominant factor over short horizons.
Annual rate of return — matters most over long horizons thanks to compounding.
Existing savings — money already saved earns interest from day one.
The model assumes end-of-month deposits and a constant rate — real returns vary year to year.
💡 Useful Tips
Start early — compounding makes an extra year of saving worth more than a bigger deposit later.
Compare savings vehicles with higher rates — the difference compounds.

Frequently Asked Questions
Does the calculation include compound interest?
Yes. Interest is compounded monthly on the accumulated balance.
What if the rate is 0%?
The remaining amount is divided by the monthly deposit, rounded up to whole months.
Does it account for taxes on gains?
No. Capital-gains tax will reduce actual returns — factor it in for long horizons.
