How 401(k) Savings Grow

A 401(k) is an employer-sponsored retirement plan with tax advantages. Contributions grow tax-deferred, and many employers match a portion of your contributions.

Formula

FV = PMT × [((1+r)^n - 1) / r] + PV × (1+r)^n
Add employer match: FV += EmployerMatch × PMT × [((1+r)^n - 1) / r]

Steps

Enter your current 401(k) balance.
Input your annual salary and contribution percentage.
Enter your employer's match percentage.
Set the expected annual return rate and years until retirement.
