Formula used

The calculator applies the gap-with-inflation equation:

$$ A = (E – I)\times(1 + r)^{n} $$

• A – annual amount you must cover in retirement
• E – estimated annual expenses
• I – expected annual income
• r – inflation rate (decimal)
• n – years until retirement

Example calculation

Inputs: age 35, retire 60, expenses 70 000, income 25 000, inflation 3 %.

Steps:

• Gap today: 70 000 − 25 000 = 45 000
• Years until retirement: 60 − 35 = 25
• Inflation factor: (1 + 0.03)^{25} ≈ 2.094
• Needed in first retirement year: 45 000 × 2.094 ≈ 94 230 USD

FAQ

What does the calculator measure?

It estimates the annual shortfall between your expected expenses and guaranteed income, then adjusts that gap for inflation until your retirement start date (BLS, 2022).

Which inflation rate should I enter?

Use a historical average—3 % aligns with the U.S. 30-year mean (Federal Reserve Economic Data, 2023). Adjust higher if you expect faster price growth.

How accurate is the estimate?

The output is as reliable as your inputs; unexpected health costs or market swings can change outcomes. “Projections are planning tools, not guarantees” (FINRA Investor Education, 2023).

How can I reduce an income gap?

Increase savings, delay retirement, lower spending, or add income streams such as part-time work or annuities (AARP Retirement Guide, 2023).

Does the tool account for investment returns?

No. It focuses on inflation. To include portfolio growth, run a separate analysis with expected real return assumptions (Morningstar Methodology, 2023).

Can I run multiple scenarios?

Yes. Change one variable—like retiring at 62 versus 68—to see how the required annual amount shifts. Scenario planning helps prioritize trade-offs (Vanguard Research, 2022).

What is a safe withdrawal rate?

Financial advisors often cite 4 % of initial portfolio value, adjusted for inflation (Bengen, 1994). Review annually against market conditions.

Why adjust for inflation?

Inflation erodes purchasing power; $1 today buys only $0.56 of 1990 goods (BLS CPI Inflation Calculator, 2023). Adjusting keeps your future budget realistic.
