Technical notes
Savings Calculator compounds your monthly deposits with FV = P·((1+i)^n − 1)/i at the rate you enter.
Compounds the monthly deposits and rate you enter; it excludes fees and taxes.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
Worked example
Saving 5,000/month at 7% annual for 3 years grows to about 199,650.5 (monthly compounding).
FAQ
What does this savings tool project?
It grows your existing balance plus each monthly contribution at the expected return, then reports the future balance and the total amount you put in.
Does the Savings Calculator send my data to a server?
No. The Savings Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
How is this different from the savings goal tool?
This starts from what you have and projects a future balance; the goal tool starts from a target amount and tells you the monthly saving required to reach it.
Can I leave the monthly contribution blank?
Yes. Enter only current savings to grow a lump sum, or only a monthly amount to model contributions from zero; at least one is required.
