How is interest applied?

The annual rate is divided by 12 and the balance compounds monthly. In time mode, each monthly contribution is added after that month’s growth.

What happens when the goal cannot be reached?

Time mode stops after 1,200 months. With no contribution and insufficient growth, the page reports that the current inputs do not reach the goal.

Does the estimate account for fees, taxes, or inflation?

No. It models a fixed monthly contribution and fixed annual rate. Actual returns, fees, taxes, and purchasing power can differ.

How it works

The calculator compounds your balance monthly. To find the time, it adds your contribution each month (plus interest) until you hit the goal. To find the required monthly amount, it solves the annuity formula for your chosen number of months. Estimates only — real returns and inflation vary.
