Calculate how much money you will have when you retire. Input your 401(k) balance, monthly contributions, and age to project your nest egg.
A common rule of thumb is the 4% rule, which states you need a nest egg equal to 25 times your annual expenses. For example, if you want to spend 40,000 a year in your currency, you need a starting nest egg of 1,000,000.
This calculator provides nominal (unadjusted) future values. To estimate your real purchasing power, you can reduce your expected return by the average inflation rate (e.g., use 6% instead of 9%).
As early as possible! Due to compound interest, starting at age 25 with a small monthly contribution often yields a larger nest egg than starting at 40 with a massive monthly contribution.
