RMD at age 88: divide by 13.7
At 88, the IRS Uniform Lifetime Table figure is 13.7. Divide your IRA balance at the end of last year by 13.7 to get this year's required minimum distribution. That is about 7.30% of the balance.
| Balance on December 31 last year | RMD at 88 | Per month |
|---|---|---|
| $50,000 | $3,650 | $304 |
| $100,000 | $7,299 | $608 |
| $250,000 | $18,248 | $1,521 |
| $500,000 | $36,496 | $3,041 |
| $750,000 | $54,745 | $4,562 |
| $1,000,000 | $72,993 | $6,083 |
| $2,000,000 | $145,985 | $12,165 |

How 88 compares with the years around it
At 87 the figure was 14.4. At 89 it will be 12.9, so the required share rises to about 7.75%. The figure falls every year, which is why the share you must take out keeps growing with age.
If your spouse is more than 10 years younger
When your spouse is the sole beneficiary and more than 10 years younger, the IRS uses its joint life table (Table II) instead, and the figure is larger, so the required amount is smaller. At 88:
- Spouse aged 77: divide by 14.3, about 6.99% of the balance.
- Spouse aged 73: divide by 17, about 5.88% of the balance.
- Spouse aged 68: divide by 20.8, about 4.81% of the balance.
The rest of the rules
Each year after the first, the distribution is due by December 31. If you have more than one traditional IRA, work out the amount for each one; you can then take the total from any one or more of them. Taking extra one year gives no credit toward the next. A qualified charitable distribution counts toward the amount. See the RMD rules and giving from an IRA.
