How Long Will $250,000 Last?

$250,000 represents serious financial security and can support early retirement planning. At $5,000/month expenses, $250k lasts about 4 years without any returns. With modest investment returns (5%), this extends to 5+ years. Combined with Social Security or part-time income, $250k can provide decades of support.

How we calculate how long your money lasts
Step-by-step breakdown of the runway shown in the calculator above (simple mode). Last reviewed 2026-06-22.

The runway duration above comes from your savings, monthly expenses, income, optional one-time costs, and inflation setting—not a third-party feed. We simulate month by month: each period we subtract expenses (and add income), optionally growing expenses for inflation, until the balance reaches zero or income covers spending. Below are the formulas, the order we follow, and worked examples you can check by hand.

Formulas

LineFormula
Effective savingsCurrent savings − one-time expense (minimum 0)
Monthly burn (no inflation)Monthly expenses − monthly income
Quick estimate (no inflation)⌈Effective savings ÷ monthly burn⌉ months
Monthly inflation factor(1 + annual inflation % ÷ 100)^(1/12) applied each month after month 1
Each simulated monthBalance = prior balance − expenses + income
Indefinite runwayWhen monthly income ≥ monthly expenses, savings do not deplete

Order of operations

1

Start with usable savings

Subtract any one-time expense from current savings

Planned large purchases (moving costs, medical bills) reduce the balance available for ongoing monthly spending before the simulation begins.

2

Compute monthly burn

Expenses minus income each month

If income fully covers expenses, runway is indefinite—the calculator stops with a message that savings will remain stable or grow.

3

Simulate month by month

Subtract net burn until balance ≤ 0

We count each month until savings are exhausted. This matches how emergency funds are actually drawn down over time, not a single lump-sum division.

4

Grow expenses when inflation is on

Multiply monthly expenses by monthly inflation rate after month 1

Simple mode uses one annual inflation rate (country default or your custom rate). Advanced mode can apply category-specific rates, spending levels, and emergency events.

5

Report duration and per-paycheck context

Total months → years + months; build timeline chart

The headline duration is the month count when balance hits zero. We also show monthly breakdown rows (up to 120 months) for the chart.

Worked example

How Long Will $250,000 Last?

Effective savings: $250,000

Monthly burn: $5,000 − $0 = $5,000/mo

Runway: 50 months (4 years and 2 months)

No-inflation check: $250,000 ÷ $5,000 ≈ 50 months (simulation may add 1 month when balance goes negative mid-period)

Line itemAmount
Current savings$250,000
One-time expense$0
Effective savings$250,000
Monthly expenses$5,000
Monthly income$0
Monthly burn$5,000
Total months50
Duration4 years and 2 months

One-time cost: One-time $5,000 expense before monthly drawdown → 1 year and 1 month.

Inflation on: With US inflation enabled (2.7% planning rate) → 1 year and 3 months (avg expense $3,556/mo).

What we do not model on this page

Simple mode uses flat monthly expenses and income unless inflation is enabled—we do not model investment returns on savings, variable paycheck timing, taxes, or exact pay dates. Advanced mode adds spending levels, income stops, emergency events, and category inflation but is still a planning estimate. Inflation rates are long-term planning assumptions, not live CPI feeds. Results are illustrative, not financial advice.

Frequently asked questions

It depends on your other income sources. $250k alone is insufficient for most US retirements, but combined with Social Security (~$1,800/month average), you'd have $10,000/year (4% rule) + $21,600 = $31,600/year - manageable in low-cost areas. Delaying Social Security to maximize benefits helps significantly.

At 60, you're likely 2 years from Social Security eligibility. If expenses are $4,000/month, $250k lasts 62 months standalone. Once Social Security kicks in (age 62+), $250k becomes supplemental income lasting potentially 15-25+ years depending on draw rate.

For traditional early retirement (age 50-55) in the US, $250k is typically not enough alone. You'd need $40-60k/year for 30+ years. However, for "barista FIRE" (part-time work + savings), $250k providing $10k/year + $25k part-time income = $35k/year, which can work.

Asset allocation depends on your timeline. 5-10 years out: 60% stocks, 40% bonds. 10+ years: 80% stocks, 20% bonds. Keep 1-2 years expenses in high-yield savings. Use tax-advantaged accounts (401k, IRA, HSA) first. Low-cost index funds are ideal.
