Retirement Calculator

A free retirement calculator that projects how a starting balance and steady monthly contributions compound between now and your retirement age. It splits the projected balance into your contributions, employer contributions, and investment growth, and includes a 401(k) view with employer-match math and a withdrawal view that estimates how long savings last in retirement. Everything is computed in your browser from the assumptions you enter. Markets do not return a fixed percentage every year, so treat the result as a planning estimate — not financial advice, a return guarantee, or a plan recommendation.
