How much do you need to retire?

There isn’t one number that fits everyone. What you need depends on what you’ll spend, what income keeps coming in, and how long your money has to last.

Start with your spending. Look at what you spend today, then at what changes once work stops. A mortgage may be paid off and commuting ends, while travel, hobbies and healthcare often grow.

Count the income that keeps coming. Social Security, a pension, part-time work, rent from a property or an annuity all cover part of what you spend.

Your savings cover the rest. The gap between spending and income is what your savings need to pay, year after year, through good markets and bad ones, for as long as you live.

Rules of thumb, like spending 70 to 80 percent of what you spend today, are a fair place to start. They can’t tell you whether your own plan holds up. Seeing your spending, income and savings together, year by year, can.
