How this calculation works

What each input means

Current savings — Starting balance before monthly contributions.
Monthly contribution — Added at the end of each month in the simulation.
Years — Number of years to project (converted to months).
Expected annual return (%) — Nominal rate converted to a monthly rate r = (annual ÷ 100) ÷ 12; use 0 for no growth (contributions only).

Formula used

Month-by-month: balance = balance × (1 + r) + monthly contribution for years × 12 months. This is a simplified projection, not tax-adjusted or inflation-adjusted.

Does not model employer match, contribution limits, or withdrawals; compare with the 401(k) tool for salary-percent contribution patterns.
