How to Build a Retirement Spending Plan

A retirement spending plan converts your savings balance into a single monthly number you can spend without wrecking year twenty. This guide shows you how to build one: which accounts to withdraw from first, how to set guardrails, and what your spending number becomes month by month through a market drop. It's general education from a budgeting app founder, not personal financial or tax advice, so check your own numbers with a fiduciary advisor or tax professional before you act on them.

What is a retirement spending plan and how does it differ from a budget?

A budget allocates income you already have

If you budget today, you're dividing money that already arrived: a paycheck, a tax refund, a freelance payment. Envelope budgeting and zero-based budgeting both start there. You give every dollar a job because the dollars exist.

A spending plan converts savings into income you'll create

In retirement, the paycheck stops and the problem flips. A retirement spending plan is the rule that turns a pile of savings into a monthly number. The best-known starting point is the 4% rule, from William Bengen's 1994 research and later the Trinity study, but a real plan adjusts that number as markets move.

Why the one-number framing works for retirees

If you're used to asking "what can I spend today?", a spending plan keeps that habit, just sourced from savings and retirement income instead of a paycheck. Once your monthly withdrawal lands in checking, it's ordinary money to budget, and that part is what apps like Tovari Financial handle.

How do you turn your savings balance into a monthly spending number?

1. Total your savings and subtract what's already reserved.
2. Pick a starting withdrawal rate.
3. Divide by 12, add other income, and adjust for this month's known bills.
4. Keep a buffer for irregular expenses.

Step 1: List your buckets and reserved expenses

Write down every account balance, then subtract money that isn't spendable: the property tax due in November, the insurance premium, cash parked for the car you know is dying.

Step 2: Pick a starting withdrawal rate

Use 4% of your spendable balance as an annual figure. It's a starting point, not a promise; a later section covers guardrails for adjusting it.

Step 3: Do the monthly math with a worked example

Say you have $300,000 saved and $10,000 of it is reserved for bills already scheduled this year. That leaves $290,000. At a 4% withdrawal rate, $290,000 × 0.04 = $11,600 for the year, divided by 12 = about $967 a month. If this month also has a $150 insurance premium you didn't reserve for, you have $817 left for everything else from savings.

Social Security, a pension, or part-time pay comes on top. The 4% applies to your savings only, so add that income to get your real monthly number, and remember that withdrawals from tax-deferred accounts may be taxed, so set aside for that too.

The subtraction matters as much as the rate: skip it and you'll spend money in March that November's property tax already owns. Tovari won't work out a withdrawal rate. But if you schedule your monthly withdrawal and Social Security as income and your bills as bills, its Safe to Spend number shows what's left in your checking account, on the web or on your phone.

Step 4: Handle irregular expenses like car repairs and medical bills

Keep a rolling buffer inside your monthly number. When a repair hits, it comes from the buffer first, not from next month's spending.

Which accounts should you withdraw from first in retirement?

The common order is taxable first, tax-deferred second, Roth last. Taxable accounts come first because when you sell there, your gains are usually taxed at capital gains rates, often 0% or 15%, and your other accounts keep compounding sheltered. Tax-deferred accounts like a traditional 401(k) or IRA come second because withdrawals are generally ordinary income, taxed at your marginal rate in the year you take them. Roth comes last because it has no required withdrawals during your lifetime and qualified withdrawals are tax-free, which makes it a good reserve for surprise expenses and a good asset to leave behind. That order is a default, not a law: it assumes your brackets look normal, your RMDs are years away, and your spending needs are steady. Treat the sequence as a starting position you revisit at every annual reset, not a rule you set once and forget.

When to break the order

The sequence shifts when your tax bracket is unusually low. Filling up a low bracket with Roth conversions or IRA withdrawals in early retirement can cut lifetime taxes, which is the argument for spending taxable money while converting. A tax advisor should check your specific brackets before you commit.

RMDs complicate the sequence

The IRS requires minimum withdrawals from most tax-deferred accounts each year starting at age 73, whether you need the money or not. That moves to 75 for people born in 1960 or later. Missing one can trigger an excise tax (IRS guidance on RMDs). RMDs force tax-deferred withdrawals earlier than the standard order suggests, so build your monthly number around them. The sequencing itself is a tax decision, not an app feature, and Tovari doesn't do it.

How much can you safely spend each year without running out?

Where the 4% rule comes from and what it assumes

The 4% rule came from historical backtests of stock-and-bond portfolios: withdraw 4% of your starting balance in year one, adjust that dollar amount for inflation after that, and the money lasted 30 years in the large majority of the periods tested. It assumes a steady withdrawal, a 30-year horizon, and a future that looks something like the past. It is a starting number, not a plan.

Why a fixed rate fails in a bad sequence

Retire into a bear market and a fixed withdrawal can drain your savings fast, because you're selling shares at the bottom to fund the same spending. The rule also ignores your real life: a car repair or medical bill does not care what year it is. A fixed rate gives you one number for 30 years, when your actual needs change every month.

Guardrails: a ceiling and a floor

Guardrails replace the fixed rate with a range. You might set a ceiling (say, 5%) and a floor (say, 3%) of your current balance, and adjust spending when you drift outside them. Up years can buy you a raise; down years mean a trim, not a panic. It's the same instinct as envelope budgeting: give every dollar a job, then rework the plan when cash flow shifts.

How should your spending plan change after a market drop?

The setup: Pat and Sam, $600k, $2,400/mo target

Say Pat and Sam, both 63, have $600,000 saved and want to draw $2,400 a month. Their rule is simple: if the portfolio falls 20% below its high, they cut 10%, and when it recovers to within 15% of the high, they restore the full amount. It's a simplified version of the guardrail idea in Guyton and Klinger's withdrawal decision rules, which measure the current withdrawal rate rather than the drop from a high.

Months 1–6: the drop and the first guardrail breach

The drop hits the 20% guardrail in month 4, when $480,000 is exactly 20% below the $600,000 high, so $2,400 becomes $2,160. They cut the dining and travel envelopes, not the medical one, because at 63 they're still two years from Medicare eligibility at 65 and pay more of their health costs themselves.

Months 7–12: holding and the recovery

Months 7 through 9 they hold $2,160 while the portfolio stays near $470,000. In month 10 a rebound takes it to $510,000, which is 15% below the high, so they restore $2,400. Whatever they didn't spend from an envelope during the lean months can roll forward, like a small holiday fund.

What the example teaches about cutting vs. freezing

They trimmed flexible spending rather than cutting everything evenly, so the medical envelope stayed whole. Notice too that a 10% cut doesn't bring them back under a strict 5% ceiling: $2,160 a month is $25,920 a year, or about 5.5% of $470,000. Holding 5% would mean about $1,958 a month. Neither rule is the right one. Choose one, write it down, and follow it when you're scared. Tovari won't run guardrails for you, but a budget with envelopes makes the trim easy to carry out.

What spending categories deserve a buffer in retirement?

Three categories are especially good at breaking a retirement spending plan: healthcare, repairs, and family support. Each one is irregular, hard to predict, and large enough to wreck a month if you treat it like a normal envelope.

Healthcare before Medicare and after

The gap between leaving work and Medicare eligibility at 65 can be an expensive stretch. Premiums, dental, and vision come out of pocket, and one surprise claim can eat two months of spending. Medicare doesn't end this either, since it has its own premiums and out-of-pocket costs. Size this buffer from your actual expected premiums plus a fixed amount for out-of-pocket costs, and keep it in its own envelope, not merged with groceries.

Home and vehicle repairs

A roof, a furnace, or a transmission does not care that your budget balanced last week. Estimate annual repair costs for your home's age and your vehicles' mileage, divide by twelve, and roll over the unspent balance every month. When the repair hits, the envelope is already funded.

Kids, grandkids, and saying no

Family support is the buffer people often forget to plan for. Decide in advance what you will give, put it in an envelope, and treat requests beyond it as a conversation, not an obligation. A spending plan you cannot defend to family is a plan you will abandon.

How often should you revisit your retirement spending plan?

Check the plan on three clocks: monthly, quarterly, and annually, plus whenever something breaks.

Monthly: reconcile and update the number

Reconcile transactions, confirm withdrawals landed, and recompute what's left to spend. It's the same habit you used while working, just with savings instead of a paycheck.

Quarterly: check the guardrails

Compare actual spending against your plan and check your portfolio against your rule. Housing, transportation, food, and healthcare are the biggest spending categories for older households in the Bureau of Labor Statistics' Consumer Expenditure Surveys, so those deserve the closest look.

Annually: reset the plan

Once a year, revalue the portfolio, adjust for inflation, and rebuild the monthly number from scratch.

Event triggers: a drop, a bill, a life change

A market drop, a large medical bill, or a family change all justify an off-schedule review. Don't wait for the calendar.

Can a budgeting app handle a retirement spending plan?

What to look for in a tool

Part of a retirement spending plan is long-range and part is day to day. For the day-to-day part, you want a monthly spending number that updates as balances change, categories you can flex after a market drop, and a clear signal when a bank connection breaks so your number doesn't quietly go stale.

Running the same checklist on Tovari, honestly

Tovari covers the day-to-day part. It gives you one Safe to Spend number, an optional envelope budget with rollover, and scheduled bills and income, for $5.99/mo or $44.99/yr after a 14-day trial with a card required. Where it falls short for retirees: it does not model withdrawal sequencing across a 401(k), IRA, and taxable accounts, it doesn't calculate a withdrawal rate or run guardrails, and it has no multi-year projection. Safe to Spend counts checking, and savings if you turn it on, but never investment accounts, so your retirement balance won't inflate the number. YNAB and Monarch handle envelopes and budgeting well too, and neither is a retirement planner. Our comparison pages cover where each app does better. Match the tool to the gap.

When a spreadsheet is still the right answer

If your plan hinges on sequencing withdrawals and testing guardrails against market drops, a spreadsheet does that math better than any app here. Use an app for daily spending and the spreadsheet, ideally with a professional's eye on it, for the long view.

FAQ

What is a retirement spending plan?

It is a rule that converts savings into one monthly spending figure. You total your accounts, subtract reserved funds for scheduled bills, apply a withdrawal rate, divide by 12, add other income like Social Security, and adjust for known expenses. Unlike a budget, it creates income from savings rather than dividing existing income.

How much can I spend each month in retirement without running out?

A common starting point is 4% of your spendable balance per year, plus income like Social Security. With $290,000 spendable, that is about $967 a month from savings. No rate guarantees you won't run out. Many people prefer guardrails to a fixed rate: set a range, take a raise in strong years, and trim in weak ones.

Should I withdraw from my 401(k) or Roth first?

The usual order is taxable first, tax-deferred second, Roth last. Selling taxable assets usually means capital gains rates, often 0% or 15%, while sheltered accounts keep compounding. Roth comes last because it has no required withdrawals during your lifetime. Break this order when your bracket is unusually low, and have a tax advisor check it.

How do I adjust my retirement spending after a market crash?

Use guardrails tied to your portfolio. For example, if it falls 20% below its high, cut spending 10%, trimming flexible envelopes like dining and travel before medical ones. Hold the reduced number while markets stabilize, then restore spending on a meaningful rebound. A crash means a trim, not a panic or full freeze.

Is the 4% rule still safe?

It is a starting number, not a plan. It came from historical backtests assuming a steady withdrawal over a 30-year horizon, and it can fail if you retire into a bear market and keep selling shares at the bottom. Treat it as an opening figure, then adjust with guardrails and reserved expenses.
