Free Financial Calculator
Free retirement calculator. Estimate if your current savings and monthly contributions will meet your desired retirement income, project your balance at retirement, and see what you still need to save.
Formula
Balance = P(1 + r)^n + PMT × [((1 + r)^n − 1) / r]; Corpus = Annual Spend ÷ Withdrawal Rate
A sustainable retirement plan balances your desired lifestyle now with the income you will need later. This tool shows whether you are on track and quantifies any monthly savings gap so you can adjust before it becomes a problem.
Inflation erodes purchasing power over the decades. The calculator inflation-adjusts your desired monthly income so the target you see reflects what future dollars will actually need to buy.
A common guideline is to replace 70%–80% of your pre-retirement income. This calculator projects your future balance and compares it against a target corpus based on your desired retirement spending and a safe withdrawal rate (typically 4%).
A safe withdrawal rate is the percentage of your retirement savings you can withdraw each year without depleting it over your expected lifetime. The 4% rule is a widely cited starting point, though your personal situation may differ.
Earlier contributions benefit from more compounding periods. Because investment growth builds on itself, starting in your 20s or 30s can mean needing far smaller monthly amounts than starting later in life to reach the same target.
