How should you enter detailed retirement spending?

Simple and Detailed modes answer different questions

Simple Monthly Total multiplies one monthly amount by 12. It is appropriate for an early estimate or a household that already maintains a reliable annual budget elsewhere.

Detailed Spending Plan adds all monthly categories, multiplies that total by 12, and then adds the annual irregular categories. That sum becomes Calculated First-Year Annual Spending. Temporary debt payments and one-time expenses are kept outside that regular total and added only in their applicable years.

Switching modes does not erase the other mode's values. When moving to Detailed mode, review Other / Unallocated Monthly Spending carefully and reduce it as amounts are assigned to named categories. Otherwise, the original broad estimate and the new category amounts may both be counted.

Start with real spending records

Gather several months of checking-account and credit-card transactions, recurring bills, insurance notices, property-tax statements, and a list of large costs from the last few years. A full year is more useful when spending varies by season. The federal consumer.gov budget worksheet can help organize expenses before entering them in the planner.

1. Remove work expenses that will genuinely stop after retirement.
2. Add costs likely to begin or increase, such as travel, hobbies, health coverage, or home services.
3. Use gross household spending, not income or account withdrawals.
4. Separate recurring costs from debts that end and purchases that happen once.
5. Keep an explanation outside the app for flexible categories that could be reduced during weak markets.

How to use the monthly categories

Use annual irregular expenses for costs that repeat

Some costs occur every year but not every month. Enter the expected annual amount for property taxes, home and vehicle repairs, travel, gifts and charity, insurance, and other irregular spending. The planner includes these amounts in regular first-year spending and increases the combined regular spending total using the selected inflation path in later years.

An annual repair allowance is different from a known roof replacement. The allowance represents recurring maintenance and belongs in Annual Home and Vehicle Repairs. A specific $25,000 roof planned at age 72 belongs under One-Time Expenses. Use both only when the annual allowance intentionally excludes the major project.

Model debts that end during retirement

Temporary Debt Payments are useful for mortgages, vehicle loans, student loans, personal loans, or a planned payoff of an existing credit-card balance. For each debt, enter the monthly payment, first applicable age, and the final age after which the payment ends. The starting and ending ages are inclusive complete projection years, so a payment from age 65 through age 69 is modeled for five annual rows.

Choose Fixed Payment when the dollar amount remains level. Choose Increases with Inflation only when the payment itself is expected to grow. Most conventional loan payments are fixed, even though associated taxes, insurance, or maintenance may increase.

The planner models the payment cash flow, not the outstanding principal, interest, amortization schedule, refinancing, extra payments, or a payoff calculation. Verify the end age from the actual loan schedule.

Add major costs in the year they occur

One-Time Expenses can represent a vehicle, roof, major trip, family gift, move, home renovation, or another known single cost. The expense is added during the complete calendar year in which the primary person reaches the selected age.

• Today's Dollars means the amount is expressed in current purchasing power. The planner increases it using cumulative modeled inflation through the selected year.
• Future-Year Dollars means the entered number is already the expected amount in that future year, so the planner does not inflate it again.

Avoid entering a future estimate as Today's Dollars if the estimate already includes expected price increases. The Bureau of Labor Statistics explains how inflation changes purchasing power and constant-dollar comparisons.

Know what the spending total excludes

• Income taxes: Do not enter them as spending. The projection calculates federal and selected state income tax separately.
• Roth conversion tax: It is part of the modeled tax calculation, not a spending category.
• Savings transfers: Moving money between accounts is not household consumption.
• Medicare and healthcare: Include them in spending when using the simple Medicare treatment. If Custom Medicare says Annual Spending excludes healthcare, let that panel add the modeled costs instead.
• Recurring income: Enter pensions, annuities, work, and rental income under Other Income rather than subtracting them from spending.

How inflation and survivor spending are applied

Regular detailed spending—monthly categories plus annual irregular amounts—uses the selected economic inflation path after the first projection year. Inflation-adjusted debts use that same cumulative path; fixed debts do not. Today's-Dollar one-time expenses use cumulative inflation through their event year.

In a Married Couple plan, the survivor percentage reduces regular spending after the modeled spouse death. Debt payments and one-time expenses keep their entered timing and amounts rather than being reduced automatically. Review those entries to ensure they still make sense for the survivor.

Review the results after adding detail

1. Confirm Monthly Expense Total, Annual Irregular Total, and Calculated First-Year Annual Spending in the input panel.
2. Open Year-by-Year Details and compare Regular Spending, Debt, and One-Time columns around payoff and purchase years.
3. Check whether a large expense creates an unusually large taxable IRA withdrawal, tax bill, or IRMAA effect.
4. Compare success through the horizon and ending ages after running Retirement Risk Analysis.
5. Test an essential budget and a more comfortable budget instead of relying on one precise estimate.
6. Download the plan report to preserve the detailed categories and timed expenses used for the projection.

Clear Detailed Entries safely

Clear Detailed Entries removes the detailed monthly and annual category amounts, temporary debts, and one-time expenses after confirmation. It does not erase the separate Simple Monthly Total. If you only want to compare modes, switch the dropdown without clearing; the detailed entries remain available when you return.
