Translate retirement or financial-independence spending from today's dollars into future dollars.
Account for reliable fixed income and a planning withdrawal rate when estimating the portfolio target.
Chapter 3.1
Understand the step
Start with the principle, then connect it to the numbers and tradeoffs that shape the decision.
The lesson
This lesson gives you two separate planning targets. Number 1 is the cash reserve that protects your household today. Number 2 is the invested portfolio that may support retirement or financial independence later. Each number has a different job, timeline, and calculation.
Where this step fits
Step 2 captures available employer compensation. Step 3 gives the rest of the Blueprint two measurable targets: the cash that protects your household and the portfolio that supports future freedom. Step 4 uses that clarity to focus on high-interest debt.
Find your full emergency-fund target
The starter emergency fund from Step 1 handles the first unexpected expense. The full emergency fund is designed for a longer income interruption. Build it from the monthly costs that must continue, not from total lifestyle spending.
Build the minimum monthly baseline
Add housing, utilities and core essentials such as groceries, insurance, essential transportation, required family costs, and minimum debt payments. Leave out optional lifestyle spending, extra debt payments, and investing because those amounts could pause during an emergency.
Use income diversity to choose three or six months
The MMA planning default uses six months when the household depends on one primary income or when multiple incomes share one employer. It uses three months when two or more meaningful income sources are independent. This is a planning heuristic, not a universal rule; variable income, dependents, health needs, or a harder-to-replace job may support holding more.
- One primary household income: six months.
- Multiple household incomes tied to the same employer: six months.
- Multiple independent employers or businesses: three months.
- Show the exact result, then round up to the next $1,000 for a simple buffer.
Find your retirement or financial-independence target
Estimate the annual amount you would want available in retirement or financial independence using prices you understand today. Then compound that spending by the inflation assumption through your target age. The calculator starts at 3%, but the assumption is adjustable.
Subtract reliable income at the right time
Social Security, pensions, and annuities can reduce the amount the portfolio must supply, but use a conservative estimate and the age the income actually begins. Income that starts after your target age does not cover the first years of retirement, and not every income stream increases with inflation.
Turn the remaining income gap into a portfolio target
Subtract reliable income available at the target age from inflation-adjusted lifestyle spending. Divide the remaining annual gap by the planning withdrawal rate. A lower withdrawal rate creates a larger target. The result is a planning estimate, not a guarantee, and should be reviewed as your life and assumptions change.
Know the math
Emergency fund target
Exact target = minimum monthly expenses x 3 or 6 months
Add housing, core essentials, and debt minimums, then round the exact result up to the next $1,000 for the recommended target.
Spending at the target age
Future spending = today's annual spending x (1 + inflation rate) ^ years
This preserves the purchasing power of the lifestyle estimate as prices change over time.
Retirement target
Portfolio target = (future spending - reliable income available then) / withdrawal rate
The calculator also translates the result back into today's dollars so the two values are not confused.

Number 1
Full emergency fund
Estimate the monthly costs that must continue during an income interruption.
Minimum monthly expenses
One interruption could remove most household income, so the MMA starting point is six months. Personal risks may support a larger target.
- Rounded full-fund target
- Monthly minimum
- Exact calculation
- Target months
- 6 months
Number 2
Retirement or financial-independence target
Start with a lifestyle in today's dollars, then translate it to the year you want the portfolio to support you.
Timeline and lifestyle
Reliable income and assumptions
Fixed income keeps pace with inflation
Turn this off when the expected income stays flat in nominal dollars.
- Target at age 65
- Today-dollar target
- Future annual spending
- Fixed income at target
- Portfolio income gap
Fixed income begins after the selected target age, so it does not reduce the first-year portfolio target shown here. The full retirement calculator models those bridge years and later income.

One-income household
Minimum monthly expenses are $4,250 and one primary income supports the household.
Six months equals $25,500. Round up to a $26,000 full emergency-fund target.
Key takeaways
- The full emergency fund protects required expenses, not every part of normal lifestyle spending.
- Income concentration helps determine whether the MMA starting point is three or six months.
- Today's retirement spending and the future-dollar portfolio target are different numbers with the same intended purchasing power.
- Retirement and financial-independence targets are estimates that should be reviewed as income, spending, and timelines change.
Independent-income household
Minimum monthly expenses are still $4,250, but two meaningful household incomes come from separate employers.
Three months equals $12,750. Round up to a $13,000 full emergency-fund target.
Retirement target in two kinds of dollars
At age 35, the goal is $80,000 of annual lifestyle spending at age 65. Inflation-adjusted fixed income of $20,000 begins at 65. Inflation is 3% and the planning withdrawal rate is 4%.
The $60,000 today-dollar portfolio income gap points to a $1.5 million target in today's dollars, or approximately $3.64 million at age 65.
Chapter 3.3
Make the decision
Use the Blueprint order of operations and the Decision Framework to choose a next move that fits your household.
Think through the tradeoff
Protection number
A full emergency fund covers the minimum monthly costs that keep your household operating. Income concentration determines the MMA three- or six-month planning default, while your personal risks may justify a larger target.
Retirement number
Start with the lifestyle you want in today's dollars, translate it to your target age with inflation, subtract reliable income available then, and estimate the portfolio needed to cover the gap.
