🚪One More Year (OMY) Decision Tool
Most calculators only show the financial upside of working longer. This one weighs that benefit against what it actually costs you in prime, high-energy retirement years.

The Financial Benefit
The Time Cost
This is a genuine, non-obvious decision: working longer meaningfully improves your numbers, but it also meaningfully eats into the active years you said you expect to have. Neither side of this trade is small enough to dismiss.
Get specific about what the improved cushion actually buys you, a lower risk of cutting spending in a bad market, more margin for healthcare costs, a more conservative portfolio. Then ask honestly whether that specific benefit is worth the specific number of prime years on the table. There's no universal right answer; there is a right answer for you, and it requires being concrete on both sides rather than reasoning in the abstract.

What Is One More Year (OMY) Decision Tool?
"One More Year" syndrome is one of the most consistently discussed problems in early retirement communities: someone hits their exact financial number, then can't actually walk away. They find one more reason to keep working, a market dip, a round-number portfolio goal, a vague sense it isn't quite enough yet, and the goalposts keep moving, sometimes for years.
Most calculators only show one side of that decision: the financial benefit of working longer, usually as a small percentage improvement in some success metric. This tool shows the other side explicitly, what working longer actually costs in the active, high-energy years you have a limited supply of, so the decision can be made with both halves of the picture in view instead of just the half that's easy to quantify.
The financial math of one more year often looks compelling in isolation. Working an extra year might add $80,000 to your portfolio, reduce your required withdrawal rate by 0.3%, and push your Monte Carlo success probability from 91% to 94%. In absolute terms, those improvements are real. What the calculator can't show in that view is that you're trading 52 weeks of your highest-energy retirement years for a 3-percentage-point improvement in a probability estimate. Put concretely: if your active retirement window is 15 years, one more year working is not 'one year less of retirement.' It's a 6.7% reduction in your available go-go years. Some people do that math and decide the financial gain is worth it. Most are surprised by how small the financial improvement looks when the time cost is displayed in the same frame. A useful question to ask yourself: if someone offered you $80,000 to give up one year of your active retirement years, would you take that trade? The answer tells you more than a success probability percentage.
How This Calculator Works
The financial side projects your portfolio forward by the number of additional years you're considering working, with your stated contributions and return, and shows how much your required withdrawal rate actually improves. The time side compares those same years against your stated "Go-Go" window, the active, high-spending, high-travel years most people experience in the first phase of retirement, to show what percentage of that finite window working longer would consume. The two are then cross-referenced into one of nine recommendations.
Personal Considerations
Be clear-eyed about what this tool is and isn't: the "Go-Go years" framework is a widely used illustrative concept in retirement planning, not a precise biological measurement, and the percentage this calculator reports is a deliberately simple ratio, years working longer divided by years of active time you expect to have, not a clinical longevity model. The point isn't false precision. The point is that most people doing this calculation in their head only count the financial side, and forcing the time side into an explicit number changes the decision in a way vague awareness doesn't.
The pattern this tool is built to interrupt is specific: people who have already hit a number that would have sounded like more than enough five years earlier, who now find that number doesn't feel like enough either. That feeling is real, but it's worth noticing that it's a feeling about safety, not a fact about your portfolio, and continuing to work past the point the math actually requires is trading a strictly limited, non-renewable resource (your healthy active years) for a financial cushion with rapidly diminishing returns. If the numbers here say the financial case is minimal and the time cost is high, the right move usually isn't to find a new number to chase, it's to ask what would actually make stopping now feel safe enough.
Loss aversion is the engine driving One More Year syndrome. Working another year feels like adding safety; stopping feels like accepting risk. But this framing is asymmetric in a way loss aversion reliably produces: potential losses from leaving (market drop, underestimated expenses) are weighted far more heavily than the certain cost of staying, which is a year of active life you cannot get back. Arrival fallacy compounds the problem. One More Year often carries an implicit promise that when the next milestone is reached, the anxiety will resolve. But the research on arrival fallacy is clear: the feeling of 'enough' is not a financial threshold. It is a psychological state that a higher portfolio balance cannot produce, regardless of how many additional years you pursue it.

Frequently Asked Questions
Yes, the Go-Go/Slow-Go/No-Go framework is commonly referenced in retirement planning to describe how retirement spending and activity levels typically decline across distinct phases. The specific number of years in each phase is an individual estimate, not a fixed rule, which is why this calculator lets you set it yourself.
A true success probability requires Monte Carlo simulation across thousands of market return sequences, which this calculator doesn't run. The required withdrawal rate is a real, transparent, calculable number that moves in the same direction, showing you concretely how much safer your numbers get, without manufacturing false precision about your odds.
Nobody knows this with certainty, which is exactly why it's worth setting deliberately rather than ignoring. A reasonable approach: use your current health and energy level, your family's longevity history, and how physically demanding your retirement plans are (extensive travel and outdoor activity favor a shorter, more front-loaded window) to pick a number, then revisit it periodically.
No, this tool is built to give an honest answer in both directions. When the financial benefit of working longer is genuinely substantial and the time cost is genuinely low, working longer is the right call, and the calculator says so. The goal is accuracy, not a predetermined conclusion that retiring sooner is always better.
