How This Calculator Works

Use this retirement savings tool for quick estimation, comparison, and planning intent while keeping formula assumptions visible.

Use the retirement savings calculator to estimate whether current savings and monthly contributions could reach a retirement target over a chosen time horizon.

The calculator compounds the current balance monthly and adds each monthly contribution through the selected retirement horizon.

Formula

Future balance = current savings compounded monthly + future value of monthly contributions.

Example Calculation

$45,000 plus $600 per month for 25 years at 6% grows to roughly $550,000 before fees and taxes.
