Consider having one partner retire first while the other continues working for healthcare benefits.
Budget $15-25K/year for ACA marketplace plans before Medicare at 65. Keep MAGI low for subsidies.
Coordinate claiming strategies. Having the higher earner delay to 70 maximizes survivor benefits.
Planning financial independence as a couple is not just doubling a solo plan. Shared housing, insurance, and travel mean your combined expenses are usually 60–80% of two solo budgets — which lowers your joint FIRE number. At the same time, two careers give you two savings engines, two sets of tax-advantaged accounts, and the option of sequential retirement where one partner reaches freedom first while the other keeps income and health coverage flowing.
This calculator models each partner separately — age, income, savings rate, current investments, and target retirement age — then projects your combined portfolio year by year against one household target. It highlights the sequential FIRE milestone (when the first partner can step back) and the year you both reach full financial independence.
Already coasting? If you want to know whether you could stop saving today and still retire on time, try the Coast FIRE calculator for couples instead, or use the classic FIRE calculator for a single-person plan.

Add up your combined annual expenses (including healthcare for two), then divide by your safe withdrawal rate. For example, $90,000 in combined expenses at a 3.5% withdrawal rate means a couple FIRE number of about $2.57 million. Couples often use 3.5% instead of 4% because two-person retirements tend to be longer and healthcare costs are higher.
You do not need to merge bank accounts, but you should plan against one combined FIRE number. Expenses like housing, insurance, and travel are shared, so calculating two separate solo FIRE numbers overstates what you actually need. This calculator models both partners individually while tracking one household target.
Yes — this is called sequential or staggered FIRE. When one partner keeps working, the household keeps employer health insurance and an income stream, which lowers the portfolio withdrawal needed. The calculator shows the milestone year when your portfolio can support one partner stepping back before full joint financial independence.
Most couples use 3.25% to 4%. The classic 4% rule was built on 30-year retirements; if you retire in your 40s as a couple, a 3.5% withdrawal rate adds a margin of safety for a 40-50 year horizon and for the survivor if one partner passes away first.
An age gap changes healthcare timing (each partner reaches Medicare or national coverage age separately), Social Security or pension claiming strategy, and how long the portfolio must last for the younger partner. Enter each partner’s real age in the calculator — it projects both ages through every year of the plan.
