How Long Will My Retirement Savings Last Calculator 2026 Update
Plan your retirement confidently. This how long will my retirement savings last calculator accounts for inflation, market returns, and your withdrawal strategy. Whether you’re using a 401(k), IRA, or personal nest egg, our US-focused tool shows exactly how many years your money will last — updated for 2026 economic trends.
Estimate your retirement runway
Based on annual compounding. With inflation adjustment, withdrawals increase each year by the inflation rate. Realistic for US retirees (2026).
How long will my retirement savings last with inflation? Key variables
Your retirement longevity depends on four main drivers: starting balance, annual spending, investment returns, and inflation. Even a 1% change in withdrawal rate can shift your runway by 5+ years. Our how long will my savings last in retirement calculator uses iterative simulation — the gold standard for accuracy. For 2026, average inflation expectations hover around 2.5–3%, and balanced portfolios target 5–7% nominal returns. If you skip inflation adjustment, you might underestimate purchasing power erosion.
2026 Exclusive insight: The 4% rule revisited
Many US retirees follow the “4% rule” — withdraw 4% of initial savings adjusted for inflation. But with current bond yields and valuation, conservative retirees consider 3.5–3.8% for longer horizons. Use our calculator to stress-test your unique plan. Example: $1M savings, $40,000/year, 5.5% return, 2.5% inflation → money lasts ~27–30 years depending on sequence. Adjust numbers for your own situation.
How withdrawal rates affect longevity (2026 estimates)
Based on $800,000 savings, 5.5% annual return, 2.5% inflation, inflation-adjusted withdrawals:
| Annual withdrawal (initial) | Years of income | Ending age (if retire at 65) |
|---|---|---|
| $32,000 (4% rule) | ~31 years | 96 |
| $40,000 (5% rule) | ~23 years | 88 |
| $48,000 (6% withdrawal) | ~18 years | 83 |
| $56,000 (aggressive) | ~14 years | 79 |
Pro tip: Delaying Social Security and reducing withdrawal rate by 0.5% can add 3–5 years of financial security. Use our calculator to model partial work or part-time income adjustments.
How the "how long will my money last calculator retirement savings" works
Our tool runs a year-by-year projection (Monte Carlo–like deterministic) until the account balance hits zero. Each year: (1) Withdraw annual spending (inflated if toggle is on), (2) apply growth based on expected return. It provides exact years and months. Unlike simple formulas, this simulation handles inflation properly.

🔥 2026 market outlook: Many economists project moderate returns in the coming decade. Factoring in sequence-of-returns risk is vital — our calculator gives you a baseline runway. Combine with a bucket strategy for peace of mind.
