How Long Does Retirement Usually Last?

Retirement is not a fixed number of years

Retirement does not come with a preset end date. Some people retire for 15 years, while others spend 30 or even 40 years in retirement. Planning needs to account for that uncertainty.

Life expectancy vs planning horizon

Life expectancy is an average. It does not mean most people pass away at that age. Many live well beyond it, which is why retirement plans often assume longer timelines.

Why retiring in your 60s often means decades of retirement

Someone who retires at age 65 may reasonably plan for retirement lasting into their 90s. That can mean funding 25 to 30 years of expenses, even without extreme longevity.

Why couples often plan longer

For couples, planning usually considers the longer-lived spouse. Even if one partner passes earlier, the remaining partner still needs income.

How retirement length affects withdrawals

The longer retirement lasts, the more sensitive outcomes become to withdrawal rates and market returns. Longer timelines often require more flexibility in spending.

Common scenarios

Some people plan conservatively and adjust spending later if retirement is shorter. Others assume a long timeline to reduce the risk of running out of money late in life.
