Couples can maximize benefits if the wife collects early and the husband delays.
Written by Kathryn A. Walson, Staff Writer, Kiplinger’s Retirement Report
As married couples enter their sixties, they face an important, and difficult, decision: when to start collecting Social Security. Logically, 
But a new study tosses that logic on its head. Married women generally are better off claiming benefits at the early-retirement age of 62, while their husbands generally should wait until 69, according to Boston College’s Center for Retirement Research. The study was conducted by center director Alicia Munnell and senior research associate Mauricio Soto.
The authors set out to determine how married couples can collect the 
A key to maximizing a couple’s benefits is to increase the value of the survivor benefit, the study found. The surviving spouse is eligible to receive 100% of the higher-earning spouse’s benefits. If a husband collects at 62, his benefits, and his wife’s survivor benefit, will be reduced by 25%. If he waits until his full retirement age of 66, his widow will get his full benefit. Each year he delays, until age 70, boosts his benefit, and the survivor benefit, by 8%.

The authors calculated the optimal ages to claim benefits based on various age differences and relative earnings. If the wife’s earnings produce a benefit that’s 40% or more of her husband’s, she should claim at 62 — because her own benefit is relatively high. He should claim at 69 to maximize the survivor benefit.

Finally, wives with the lowest relative earnings should collect a spousal benefit, which she can only do when her husband retires. If there’s an age difference of five or six years, he should wait until 68 and she should collect at 62. If they’re the same age, they should both collect at 66; the spousal benefit is less important because they’ll be spending most of their retirement together.

Despite the advantages of claiming benefits early, Munnell says that
