🏖️ Retirement Calculator ☆

Overview

Our Free Retirement Calculator is a free online financial planning utility that helps you map out your retirement savings and understand exactly how much you need to retire comfortably. Early in a career or a few years from retirement, the calculator compounds growth on current savings, adds monthly contributions and projects the total nest egg at your target retirement age. Input your current age, retirement age, current savings, monthly contribution amount, expected annual return rate, and inflation rate. The calculator shows conservative, moderate, and optimistic projection scenarios with year-by-year growth tables. It also computes your FIRE number, the total savings needed to achieve financial independence based on the 25x annual expenses rule. Adjust any variable and see results update instantly. All calculations happen entirely in your browser. Your financial data never leaves your device and is never stored or transmitted. Perfect for anyone planning their financial future. No downloads, no sign-up, no data collection.

How the projections are calculated

Each year, the balance grows by the expected return, monthly contributions are added, and the result is adjusted for inflation so the projection is expressed in today's purchasing power. The calculator runs conservative, moderate and optimistic return scenarios side by side, with a year-by-year table showing contributions, growth and balance. The FIRE number applies the 25× annual-expense rule, the savings target commonly associated with a 4% withdrawal rate, and the tool shows the gap between that target and your projected nest egg at the chosen retirement age.

Savings and income figures are among the most sensitive data people type into a website. Every calculation runs locally: nothing is transmitted, stored or logged, and the page works offline after loading. Close the tab and the numbers are gone.

Planning assumptions to review

• Returns are not linear, the scenarios show a range, not a promise.
• Inflation compounds in both directions: contributions lose value over time.
• Adjust contributions upward as income grows.
• Treat the FIRE number as a starting benchmark, not a guarantee.
• Consult a licensed advisor before making decisions based on any projection.

Inflation, fees and the withdrawal phase

A projection that ignores inflation, fees and the order of returns will look better than reality. The calculator works in today's money by default: a 6% nominal return with 2.5% inflation compounds at roughly 3.5% real, and that difference is enormous over 30 years, the same contribution can end up 40% smaller in purchasing power. Fees work the same way: an expense ratio of 1% instead of 0.2% silently removes a fifth of the final balance over a long horizon, so check the total cost of the funds you hold. The withdrawal phase needs a different mindset. During accumulation, a bad year is cushioned by future contributions; in retirement, withdrawals lock in losses, which is why sequence-of-returns risk matters more than the average return. Holding one to three years of spending in cash or short-term bonds lets you avoid selling equities in a downturn. Finally, treat the result as a range, not a number: run the projection with conservative, expected and optimistic returns, and check what happens if you retire two years earlier or save 5% more. The tool stores nothing, so you can test uncomfortable scenarios freely.
