Retirement Calculator
Your retirement number, your projected savings, and the gap between them — with inflation handled honestly.
How your number is calculated
The calculator inflates your desired spending to retirement-year dollars, subtracts what Social Security covers, and multiplies the rest by 25 — the inverse of the 4% safe-withdrawal guideline:
Target = Income needed × 25
Age 35 → 67, $60,000 saved, $800/mo contributions, want $60,000/yr (today's dollars), $2,000/mo Social Security:
At 3% inflation, $60,000 becomes ≈ $154,000/yr at 67. Social Security (inflation-adjusted) covers ≈ $62,000, leaving $92,000/yr × 25 = ≈ $2.3M target.
Projected savings at 6.5%: ≈ $1.4M — a shortfall, fixable by raising contributions ~$700/mo, retiring later, or trimming the spending goal.
Savings milestones by age
| Age | Savings target (× salary) |
|---|---|
| 30 | 1× |
| 40 | 3× |
| 50 | 6× |
| 60 | 8× |
| 67 | 10× |
Behind on the milestones? The levers, in order of power: contribution rate (each +1% of salary compounds enormously — see the 401(k) calculator and grab every match dollar), retirement age (each year later adds savings, growth, and higher Social Security simultaneously), and spending flexibility.

Frequently asked questions
How much money do I need to retire?
Start with 25× annual spending from savings (the 4% rule inverted): $60,000/yr → ~$1.5M, minus what Social Security covers.
How much should I save by age?
1× salary by 30, 3× by 40, 6× by 50, 8× by 60, 10× by 67 — assuming ~15% savings rates.
What return should I assume?
6–7% nominal pre-retirement, less after; ~3% inflation. Conservative assumptions make robust plans.
Does this include Social Security?
Yes — your entered benefit reduces the income savings must produce. Check yours at ssa.gov.
