Odds a 48-year-old woman reaches each age
Life expectancy is only the average. The spread is wide: one in four 48-year-old women is expected to live past about 92, and one in ten past about 96. That is why retirement planners often plan for age 90 or later rather than the average.
| Reach age | Probability | Years from now |
|---|---|---|
| 50 | 99% | 2 |
| 60 | 95% | 12 |
| 65 | 91% | 17 |
| 70 | 86% | 22 |
| 75 | 79% | 27 |
| 80 | 67% | 32 |
What that time looks like
35.3 years is about 1,840 weeks, or 12,882 days. It also means roughly 35 more birthdays and 35 more summers on average. Enter an exact birth date in the life expectancy calculator for a result to the day.

Each year you survive, the average age you can expect to reach goes up slightly, because you have already passed the risks of the year behind you.
