How We Calculate This

This calculator uses compound growth projections with regular contributions. Retirement needs are calculated using the safe withdrawal rate (default 4%) to determine how much savings is required to generate your desired retirement income.

Frequently Asked Questions

What is the 4% rule?

The 4% rule is a guideline suggesting you can withdraw 4% of your retirement savings annually without running out of money over a 30-year retirement. It is based on historical market performance and assumes a balanced portfolio of stocks and bonds.

What is a FIRE number?

Your FIRE (Financial Independence, Retire Early) number is typically 25 times your annual spending. This is the inverse of the 4% rule - if you have 25x your annual expenses saved, you can theoretically live off 4% withdrawals indefinitely.

How much do I need to retire?

The amount you need depends on your desired lifestyle, expected pension/benefits, and withdrawal rate. A common target is having enough savings to replace 70-80% of your pre-retirement income. This calculator helps you determine your specific number.

What return should I expect?

The stock market has historically returned about 10% annually (nominal) or 7% after inflation (real). For planning, 6-7% nominal is conservative for a diversified portfolio. Bonds typically return 3-5%. Use the "Expected Return" field for your nominal rate.

What if I am behind on retirement savings?

Consider increasing your savings rate, working longer, reducing expected retirement spending, or a combination. Even small increases in monthly contributions can make a significant difference over time due to compound growth.
