Budget periods — your monthly spending plan
Set one or more budget periods. Each has a start year, end year, and monthly amount — so you can spend more in early "go-go" years and less later. Amounts are monthly and inflate automatically. This is the spending figure your whole plan runs on.
Not sure what to spend in retirement? Just enter your current monthly budget for now, then keep moving through the tabs: go to Home Equity for your housing plan, then Net Worth to fill in your assets and liabilities. Once those are done, the Smart Budget tab automatically figures out the most you can safely spend across your whole life projection — and can apply that amount back to your plan for you.

Major One-Time Expenses
NEW
Model big one-time hits that don't fit in your monthly budget — a new roof, replacement car, wedding, medical event, dream vacation, home renovation. Each expense is added to that year's total spending and drawn from the source you choose. These show as red badges on Plan Summary and Year-by-Year so you can see the impact.

Monthly spend by scenario
Home equity — sell, downsize, or stay put
Model what happens if you sell your current home and move to a smaller home or condo. The equity difference flows into your cash position and feeds through the spending waterfall.
Apply this housing plan to my plan
When ON, My Results, Net Worth, My Timeline and projections include selling your home and moving. When OFF, the plan keeps your current home (stay put).
Current home
Equity: $0
Principal & interest only. This is used to track how fast the loan is paid down for your home equity — it is not added to your spending, since your budget on the Budget tab already includes what you pay for housing. If your mortgage is paid off, or your housing cost changes after a move, add a budget period on the Budget tab for the lower amount.
Enter your principal + interest payment (not including taxes/insurance). The tool calculates the year your mortgage is paid off below.
Downsize target (new home / condo)
Equity gain: $0
For reference when planning the move. Like the mortgage, this is not added to your spending — add it to a budget period on the Budget tab starting the year you move in.

Retirement Plan Summary
Annual financial projection · active scenario shown
About the Tax column: Taxes are planning estimates, not exact return figures. This tool applies your single effective tax rate to taxable income (about 85% of Social Security plus other income, IRA withdrawals, and RMDs). It does not model graduated brackets, state taxes, capital-gains rates, IRMAA surcharges, or deductions beyond the standard deduction. Use it to compare scenarios directionally, and confirm actual numbers with a tax professional.
IRA & cash balances
Annual income sources
Your Information — Build Your Plan
This is where your plan begins. Enter your birth year (and your partner's if applicable) and plan end year (or how long you want to plan for). Then enter your income and your partner's if applicable, your projected Social Security, and the year you expect to start collecting. Other income sources — pension, annuity, rental, part-time, brokerage — are available. Then enter your cash and retirement account balances, along with your inflation and tax rate assumptions. Ballpark numbers will give you a reliable picture — then you can start dialing in your numbers. A couple of tabs have their own inputs you'll fill in separately: the Budget tab (enter your current ballpark budget to start) and the Home Equity tab (if you own a home, you can choose to model a sale and upgrade or downsize at any point in time, or stay put). Before you start, it helps to have these handy:
- Your current age and income — plus your spouse's or partner's, if applicable.
- Your Social Security details — your expected monthly payment at your minimum retirement age (find it at ssa.gov).
- Any additional or other income and investments — pension, rental, annuity, part-time work, brokerage, and so on.
- Your cash & retirement accounts — IRA/401k balances and cash savings; ballpark within a few thousand dollars is fine, they change daily.
- Inflation & tax assumptions — a general inflation rate and your working and retired tax rates (defaults are provided if you're unsure).
Don't forget the Net Worth tab — add your assets & debts (home, vehicles, loans) there.
📝 Note about the yellow "sample plan" banner at the top: The tool loads a sample plan (middle-class couple, age 45, planning to retire at 60) so you can see how everything works before entering your own numbers. Once you're ready, click "Reset" in the top right, then start entering your own information — or just edit the sample values field by field to replace them with yours.
Plan horizon
Income
This is your first full retirement year — the plan assumes no salary from January of this year. If you plan to work through part of 2027 and retire mid-year, enter 2028 (last working year is treated as a full salary year).
Same convention — enter their first full retirement year.
Leave the start years blank to use each person's Full Retirement Age (66–67 depending on birth year). Enter the benefit amount for the age you plan to claim — the tool uses the figure you type as-is. Claiming before FRA permanently reduces your benefit (roughly 25–30% at 62); waiting past FRA increases it about 8% a year to age 70. Your Social Security statement at ssa.gov shows the amount for each claiming age.
Additional income & investment streams
— enter what applies to you, leave blank otherwise
📈 Taxable Brokerage Account
Stocks, ETFs, mutual funds outside your IRA/401k. Taxed on gains when sold.
🏛️ Pension
Enter 0 for most private/corporate pensions (fixed for life). Many government, federal, or military pensions have a COLA — often 2–3% or capped at inflation. Check your plan; a fixed pension loses about half its buying power over ~24 years at 3% inflation.
Fixed monthly income from a former employer. Taxed as ordinary income. Most pensions have no COLA — enter 0 if fixed.
📋 Annuity
Fixed income from an insurance annuity contract. Partially taxable (earnings portion). Enter 0 for end year if it pays for life.
🏦 Bonds / CDs / Treasuries
Includes I-bonds, Treasuries, municipal bonds, CDs, bond funds. Interest is taxable income each year (except muni bonds).
🏘️ Rental / Investment Property Income
Net rental income after mortgage, taxes, insurance, and maintenance. For the property itself (value/equity), use the Home Equity tab.
💼 Part-time / Consulting Income
Consulting, freelance, board positions, part-time work after retiring. Taxed as ordinary income. Enter start/end years for when this income runs.
💵 Other Annual Income
Any other recurring income — alimony, royalties, a trust, side income, etc. Add as many as you need. Leave year fields blank for "always."
Cash & retirement plans or investments
The minimum cash buffer you always want to keep on hand — your emergency fund and peace-of-mind cushion. The plan won't spend below this level; once your cash reaches it, further needs are covered by your other income streams (Social Security, part-time income, pension, annuity, rental income) and by draws from your IRA/401k as needed. A common target is 6–12 months of expenses.
👤 Your IRA / 401k
👥 Spouse's IRA / 401k (leave blank if single)
Applied to both your and your spouse's IRA/401k accounts (typical for households investing similarly).
