About the Retirement Calculator
extremely high volume / year-round search with long-term planning intentThe Retirement Calculator is a free online retirement planning tool designed to help you estimate how much you need to save for retirement and whether you are on track to reach your goal. It projects the growth of your current savings and monthly contributions through retirement age, factors in Social Security benefits, and applies the safe withdrawal rate (3%, 4%, or 5%) to estimate your sustainable retirement income. Pair it with our Investment Calculator to fine-tune asset allocation assumptions or our Compound Interest Calculator for a simpler fixed-rate projection.
Enter your current age, retirement age, existing savings, monthly contribution, expected annual return, inflation rate, desired retirement income, and estimated Social Security benefit. The tool computes your projected savings at retirement, a readiness score (0-100%), and shows whether you are on track. An interactive goal planning panel calculates the required monthly contribution to close any shortfall. The age-by-age growth table details every year from now through retirement, and the starting age impact table illustrates the cost of waiting by showing how much you would accumulate if you started saving at age 25, 30, 35, 40, 45, or 50.
Formulas & Mathematical Theory
Retirement Savings Future Value
Where P is current savings, C is the monthly contribution, r is the monthly return rate, and t is the number of months until retirement.
Safe Withdrawal Amount (4% Rule)
The 4% rule suggests withdrawing 4% of the portfolio value in the first year of retirement, adjusting for inflation annually, to sustain a 30-year retirement.
