Retire early

"How much do I need?" has a surprisingly blunt answer, and it depends far more on what you spend than on what you earn.

Your target is a multiple of spending, not income

At a 4% withdrawal rate, a portfolio supports about 4% of itself per year. Invert it: you need roughly 25× your annual spending. Spending $60,000 a year sets the target below — and cutting spending moves it twice, because it lowers the target and raises the amount you save.

Saving 25% of $80k$20,000/yr
Rule of thumb25× annual spending is the shorthand for the 4% rule. It is a planning yardstick, not a guarantee — sequence of returns still matters.

Watch the savings rate do the heavy lifting

Salary changes the target slowly; savings rate changes it fast. Push the rate from 25% to 40% and the finish line moves in by years — because you are adding more and needing less at the same time.

Rule of thumbSavings rate, not investment return, is what you control. It is also the input the answer is most sensitive to.

Check what fees quietly take

A 1% annual fee sounds like nothing. Run the same twenty-year projection with and without it and the gap is not 1% — it is compounded every year against the whole balance.

Rule of thumbA 1% fee is not 1% of the outcome. Over decades it compounds into a double-digit share of the final pot.

Decide what the house does to the plan

A mortgage that ends before you do is a spending cut waiting to happen — it drops your required number permanently. One that runs into retirement has to be funded from the portfolio, which raises the target.

The number is mostly about spending

Everything in this chain points the same way: what you spend sets the target, what you save sets the speed, and fees quietly take a share of both. Put your own figures in and the tools will disagree with any round number you had in mind.
