What is the Retirement Income Analysis?

A million-dollar portfolio sounds like plenty until you translate it into a monthly paycheck. This analyzer performs that translation across every income stream you will have: portfolio withdrawals at your chosen Annual Withdrawal Rate, Social Security (Monthly), Pension (Monthly), and Other Income (Monthly). It sums them into Total Monthly Income and Total Annual Income, benchmarks your plan against the Safe 4% Withdrawal (Monthly), and estimates the Years Until Depletion so you can see whether the money outlives you or vice versa.

Hold a $1,000,000 portfolio, withdraw 4%, and collect $2,000 in Social Security with no pension. The portfolio pays about $3,333 monthly; with Social Security your total approaches $5,333 — roughly $64,000 a year. The safe-withdrawal benchmark confirms 4% as the sustainable line, and the depletion estimate stretches past 30 years. Push withdrawals to 6% and the depletion horizon shortens dramatically — the math is unforgiving past 5%.

Withdrawal rate is the master variable of retirement. Every point above 4% must be justified by a shorter horizon, lower spending flexibility, or a genuine willingness to risk the later years.

With the pre-filled defaults — Portfolio Value $1,000,000, Annual Withdrawal Rate 4%, Social Security (Monthly) $2,000, Pension (Monthly) $0, Other Income (Monthly) $0, Inflation Rate 3% — the Retirement Income Analysis returns Monthly Portfolio Income $3,333.33, Total Monthly Income $5,333.33, Total Annual Income $64,000.00, Safe 4% Withdrawal (Monthly) $3,333.33, Est. Years Until Depletion 30.0. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.

How to Use the Retirement Income Analysis

  1. 1Enter your Portfolio Value — for example, $1,000,000.
  2. 2Set your Annual Withdrawal Rate, such as 4.
  3. 3Add your Social Security (Monthly), like $2,000, plus any Pension (Monthly) and Other Income (Monthly).
  4. 4Read your Total Monthly Income — your retirement paycheck.
  5. 5Check the Est. Years Until Depletion; if it falls short of your horizon, lower the withdrawal rate.

Formula

totalIncome = socialSecurity + pension + withdrawals

Calculation Progression Roadmap

How the Retirement Income Analysis turns your inputs into a result, step by step — from the values you type to the answer you read.

01

Gather your inputs

Type in your Portfolio Value, Annual Withdrawal Rate, Social Security (Monthly), Pension (Monthly), Other Income (Monthly), and Inflation Rate. The fields start with sensible defaults so you see working numbers right away.

02

Sanity-check your numbers

Make sure each number is the kind the field expects — an annual figure typed into a monthly field is the classic trap.

03

The math runs itself

The calculator evaluates Portfolio Value × Annual Withdrawal Rate ÷ 100 ÷ 12 on every keystroke — there is no submit button to press.

04

Read your results

Your Monthly Portfolio Income, Total Monthly Income, Total Annual Income, Safe 4% Withdrawal (Monthly), and Est. Years Until Depletion appear instantly. With the pre-filled defaults, that is Monthly Portfolio Income $3,333.33, Total Monthly Income $5,333.33, Total Annual Income $64,000.00, Safe 4% Withdrawal (Monthly) $3,333.33, Est. Years Until Depletion 30.0. Change any input to see the effect immediately.

05

Test a what-if

Nudge one input up or down. Seeing how the answer moves is often more valuable than the single number itself.
