## Overview

Saving $500 a month from age 25 builds a $1.3 million nest egg by 65 at 7% — market growth ($1,072,407) is 4.5× your own contributions ($240,000). Hitting seven figures on a modest monthly amount is possible because 40 years give early contributions time to compound repeatedly. In real terms (inflation-adjusted at 2.5%) the nest egg is worth ~$488,780 today — still nearly twice your deposits.

## Method

The calculator applies the future-value formula with monthly compounding. Your current balance (PV) grows for n months at the monthly rate r = annual return / 12. Simultaneously, each effective monthly contribution (your amount plus the employer match percentage) is treated as an ordinary annuity — paid at the end of each month — and compounds for the remaining months. The two components are summed to give the nominal nest egg. The inflation-adjusted figure then divides the nominal result by (1 + inflation rate) raised to the number of years, using annual compounding. Total employee contributions, total employer match, and total growth are reported separately so you can see the composition of the final balance.
