Quantify the real cost — and benefit — of working one extra year versus retiring now on a slightly smaller portfolio.
One More Year Calculator
The One More Year Calculator helps you answer one of the hardest questions in personal finance: is it actually worth it to keep working?
It takes your current portfolio, your savings rate, your expected retirement expenses, and your investment return assumptions, then runs two parallel simulations side by side. What happens if you retire today versus what happens if you grind out one more year. The results show up as annual withdrawal income, monthly income, and how your portfolio holds up all the way to your life expectancy.
The insight that usually surprises people: the calculator frames the cost of working in daily terms. If your portfolio would generate $60,000 a year in retirement, every day you delay costs you roughly $164 in retirement income you didn't get to spend. That reframe makes the tradeoff feel real in a way that abstract portfolio numbers don't.
The chart overlays both retirement trajectories so you can see visually whether the +1 year portfolio meaningfully outlasts the retire-now portfolio, or whether the lines are close enough that the extra year just isn't worth the days.
