The 50/30/20 Budget Rule in Retirement

A split of after-tax income into three parts: 50% for needs, 30% for wants and 20% for saving and paying down debt. Elizabeth Warren and her daughter Amelia Warren Tyagi set it out in their 2005 book All Your Worth, written for working families who wanted a budget they could keep without tracking every purchase. Its appeal is that it asks only three questions: are the fixed bills within half of take-home pay, is the spending you could cut within 30%, and is a fifth going to the future?

Every part of the original assumes a working life: a paycheck net of payroll tax, a 401(k) deduction counted as saving, and debt payments that include a car loan and perhaps student loans. The structure survives retirement. The labels and the meaning of the 20% need to change.

As a check of proportion, yes; as a rule to live by, only loosely. It works once you rename the buckets for this stage of life:

• Essentials (50%): housing costs including property tax, insurance, HOA fees, upkeep and any mortgage; utilities; food; transportation; health care and insurance premiums; minimum payments on any remaining debt.
• Discretionary (30%): travel, dining, hobbies, clubs and regular help for family. The spending you raise in good years and trim in bad ones.
• Saving or giving (20%): refilling the cash reserve, reinvesting a required distribution you did not need, charity, and planned gifts to children and grandchildren.

Take Margaret, 71, and Paul, 73. Their house is paid off, they have $1.6 million in IRAs and a taxable account, and Paul's required distributions have started. After tax and Medicare premiums, their monthly income is $9,000:

Their split is 49/28/23, well within the rule. But notice what the split cannot tell them: whether the $4,400 of essentials is safe in a year when markets fall 25%. For that they need a second number, below. Our 50/30/20 budget calculator for retirement opens on their figures and shows both.

With more going to housing, health care and giving, and less to transportation, than younger households. The Bureau of Labor Statistics' Consumer Expenditure Surveys show the shares by the age of the household head (BLS, 2024):

Three patterns matter. Health care nearly doubles as a share of spending between the average household and the over-75s. Transportation falls sharply after 75, as people drive less and replace cars less often. And giving rises: households 75 and older put more than twice the average share into cash contributions. Together, essentials take a growing share with age, and the giving bucket often grows too, at the expense of discretionary spending.

These are averages across all incomes. A household with a paid-off house and a seven-figure portfolio will usually spend a smaller share on essentials and a larger share on travel and giving. Use a year of your own statements, not the averages, when you fill in the buckets.

That is the test that matters more than the split. Divide Social Security, pensions and annuity income by essential spending. At 100% or more, every essential bill is paid by income that does not depend on markets, and the portfolio pays only for discretionary spending and giving, which can be trimmed in a bad year. Below 100%, part of every essential bill depends on withdrawals.

Margaret and Paul are well covered. A bad year in the markets would touch their travel and giving, not their bills. Social Security also rises each year with a cost-of-living adjustment, 2.8% for 2026 (SSA), while most private pensions, including Paul's, stay flat. Over twenty years that shifts the coverage down slowly, which is one reason to re-run the numbers every January.

Run it for the survivor too

The coverage test should be run twice: for the couple, and for whichever spouse outlives the other. A surviving spouse receives the larger of the two Social Security benefits, not both (SSA). Suppose Paul's benefit is $2,600 and Margaret's $1,700, and Paul chose a pension that pays his survivor half, $700. If Paul dies first, Margaret's guaranteed income falls from $5,700 to $3,300. Her essentials fall far less, perhaps to $3,600, since the house, insurance and utilities cost about the same for one. Coverage drops from 130% to about 92%. Nothing is wrong with that, but it means the portfolio will carry part of her bills, and it argues for delaying the larger benefit, which becomes the survivor benefit.

If your own coverage is below 100% for the long term, the usual ways to close the gap are:

• Delaying Social Security. Each year of delay past full retirement age, up to 70, raises the benefit for life. The guide to claiming Social Security weighs the trade-off.
• Taking a pension as an annuity rather than a lump sum, or buying an income annuity with part of the portfolio. See the pension lump sum vs. annuity guide.
• Lowering housing costs, the largest essential. The downsizing guide runs the numbers on selling and moving.

Then the split will look wrong for a few years, and that is fine if the bridge is planned. Richard, 64, retired last year from a corporate job with $2.2 million saved and no pension. He intends to claim Social Security at 70 and lives on withdrawals until then. He is not yet on Medicare, so his health insurance is a large essential line.

At 64 his split is 60/30/10 and his coverage is zero: every bill depends on the portfolio. At 70, with Medicare in place and Social Security paying $4,400 a month after Part B, essentials drop to $4,100 and coverage passes 100%. His withdrawals fall from $8,000 to $3,600 a month in today's dollars.

The risk in those six years is a market fall early on, forcing him to sell to pay the bills. He handles it with a cash and short-term bond reserve covering the essentials for the bridge years, spent first in any year stocks are down. The retirement emergency fund calculator sizes a reserve in years of withdrawals, and the retirement withdrawal calculator tests whether a higher early withdrawal that falls later is sustainable. The years before Medicare are also often the cheapest years for Roth conversions; the Roth conversion guide covers the trade-off with health insurance costs.

Money that leaves this year's spending for a purpose: rebuilding reserves, reinvesting and giving. For a retiree it usually includes:

• Refilling the cash reserve. After a year of spending from cash during a market decline, rebuilding the reserve is the first call on surplus income.
• Reinvesting surplus required distributions. RMDs start at 73, or 75 if born in 1960 or later (SECURE 2.0), and often exceed what you spend. The part you reinvest in a taxable account is saving, not spending.
• Charitable giving. From age 70½, a qualified charitable distribution lets you give up to $111,000 in 2026 directly from an IRA; it counts toward your RMD and stays out of taxable income. The QCD guide covers the rules.
• Planned gifts to children and grandchildren. Up to $19,000 per recipient in 2026 without filing a gift tax return, including 529 plan contributions. See the gifting guide.
• Extra payments on remaining debt. Minimum payments are essentials; anything above them belongs here. The snowball vs. avalanche guide and the debt payoff calculator show how to clear the last balances.

Regular help, such as a monthly contribution to a child's rent, fits better under discretionary spending, because you would pause it in a hard year. Planned giving, such as a pledge or a 529 contribution, fits under saving or giving. Margaret and Paul put $500 a month into charity, $400 into two grandchildren's 529 plans and $1,200 back into the reserve or reinvested from Paul's RMD.

Expect discretionary spending to fall and essentials and giving to rise. The standard split suits the first active years; later, other splits often describe the budget better. These are illustrations, not rules:

Margaret and Paul re-run their budget for a plausible year at 80, in today's dollars. Travel falls from $1,000 to $400 a month, health care rises from $750 to $1,150 and charitable giving rises to $800. The result is 51.7% essentials, 20.0% discretionary and 28.3% saving or giving. Against 50/30/20 the giving bucket looks too large and discretionary spending too small, but nothing is wrong: they travel less and give more. They change their targets to 50/20/30, and guaranteed income still covers 123% of essentials.

Health care is the line most likely to grow. Medicare's standard Part B premium is $202.90 a month per person in 2026, with a $283 deductible (CMS, 2026), before a supplement or Advantage plan, drug coverage and dental. Higher-income households pay more through income-related surcharges; the Medicare and IRMAA guide explains them, and the healthcare cost estimator builds the line for your budget. Long-term care is a separate and larger risk, planned with insurance or a dedicated reserve rather than a monthly budget line; see the long-term care planning guide.

Start from what reaches your bank account. Social Security deposits are usually net of Medicare Part B, and of Part D if you asked for it to be withheld. Pensions pay net of withholding. For portfolio withdrawals, take the monthly average of what you draw, less the tax it generates: traditional IRA and 401(k) withdrawals are ordinary income, while Roth withdrawals and the cost basis of shares sold in a taxable account are not taxed.

If you take one large withdrawal a year, such as an RMD in December, divide it by 12. The tax bracket calculator estimates the federal tax on a year's income, and the guide to retirement withdrawal order explains which accounts to draw from first to keep that tax low. Working from after-tax figures means income tax does not appear in any bucket, which keeps the percentages comparable from year to year.

Treating the split as the goal, and leaving out the costs that do not arrive monthly. The ones we see most:

• Using gross income. A budget built on pre-tax withdrawals overstates what you can spend by the tax on them.
• Leaving out irregular costs. Cars, roofs, hearing aids and dental work arrive every few years. Budget them as a monthly average or hold them in the reserve.
• Chasing the percentages. Cutting giving because the bucket reads 28% instead of 20% misses the point. The split is a check, not a target.
• Ignoring whether the withdrawal is sustainable. A budget can fit 50/30/20 and still draw too much from the portfolio. Check the withdrawal rate separately.
• Budgeting only for the couple. Run the survivor's budget as well; income usually falls more than spending.
• Setting it once. Social Security adjusts each year, Medicare premiums change, RMDs grow. Re-run it every January.

For a line-by-line budget rather than three buckets, the personal budget planner works from the same after-tax figures.
