Expert tips

1

$1M + Social Security = $60k+/year - comfortable almost anywhere

2

Consider a 3.5% withdrawal rate for extra safety and legacy

3

Diversify: 60% stocks, 30% bonds, 10% alternatives

4

Plan for healthcare: budget $15-20k/year before Medicare

5

Consider long-term care insurance - costs can devastate even $1M

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 $1 Million Last in Retirement?

Effective savings: $1,000,000

Monthly burn: $6,000 − $0 = $6,000/mo

Runway: 167 months (13 years and 11 months)

No-inflation check: $1,000,000 ÷ $6,000 ≈ 167 months (simulation may add 1 month when balance goes negative mid-period)

Line itemAmount
Current savings$1,000,000
One-time expense$0
Effective savings$1,000,000
Monthly expenses$6,000
Monthly income$0
Monthly burn$6,000
Total months167
Duration13 years and 11 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 — How Long Will $1 Million Last in Retirement?

Runway math, emergency funds, income, inflation, and planning tips for how long will $1 million last in retirement?.

Yes, $1 million is sufficient for most retirements. The 4% rule provides $40,000/year from investments alone. With average Social Security ($21,600/year), you'd have $61,600+ annually - well above the median US household income. In most areas, this funds a comfortable retirement.

At 50, using the 4% rule ($40k/year), $1 million should last your entire lifetime. Even without Social Security for 12-17 years, $1M at 4% withdrawal with 6% average returns can last 35+ years - taking you to age 85+. This is a solid early retirement number.

For most people, yes. $1 million invested at 4% withdrawal provides $40k/year indefinitely. If your expenses are under $3,500/month ($42k/year), you can likely never work again. In low-cost areas or with frugal living, this becomes even more secure.

Start with the 4% rule ($40k/year) and adjust based on market conditions. In down years, withdraw less (3-3.5%). In up years, you can take more or reinvest. Keep 2 years expenses in cash to avoid selling stocks during downturns. Consider a bucket strategy: cash, bonds, stocks.

At $6,000/month with no income, your burn rate is $6,000/month. $1,000,000 lasts about 13 years 11 months (~166.7 months). Formula: $1,000,000 ÷ $6,000 = 166.7 months.

With 3% annual inflation, $6,000/month becomes about $6,180 after year one and keeps rising. That shortens runway by roughly 8–15% over a multi-year horizon versus a flat-expense plan. Enable inflation in the calculator above for a month-by-month projection.

Adding $1,500/month (gig work, part-time, unemployment, or dividends) drops your burn rate from $6,000 to $4,500/month. That extends $1,000,000 to about 18 years 6 months (~222.2 months) — often nearly doubling runway versus expenses-only.

A 6-month emergency fund at $6,000/month requires $36,000. $1,000,000 covers about 166.7 months of those expenses — so it meets or exceeds the 6-month benchmark. Single-income or self-employed households often target 9–12 months.

The 4% rule suggests withdrawing about $40,000/year ($3,333/month) from $1,000,000 while aiming for a ~30-year portfolio lifespan. That only works if invested returns and spending stay on track — cash sitting idle does not follow the 4% model. Use the calculator for cash runway; use 4% for invested retirement planning.

Two levers matter most: lower expenses (housing, insurance, subscriptions, food) and add income (part-time work, UI benefits, side hustles). Cutting just $400/month from a $6,000 burn rate extends $1,000,000 by roughly 11.9 months. Keep cash you need within 1–2 years in a high-yield savings account.
