The Triple Benefit of Working One More Year

When you delay retirement by one year, three things happen to your pension simultaneously: (1) Your years of service increase by one, adding multiplier × salary to your annual benefit. (2) Your final average salary may increase if the additional year is a higher-salary year. (3) You reduce or eliminate any early retirement reduction that would have applied. The combined effect is larger than most employees realize.

📈Working to 62 vs. 57 on $75K

Waiting from 57 to 62 to retire increases this pension from $2,813/month to $4,375/month — a difference of $1,562/month. Over a 25-year retirement, that’s $468,600 more in lifetime pension income.

The Break-Even Analysis

When deciding whether to work another year, calculate the break-even point: how long does it take for the higher pension to recoup the foregone year of pension income? A social worker who delays from 58 to 59 and gains $200/month in permanent benefit forfeits 12 months × $2,900 (her benefit at 58) = $34,800 in foregone payments. At $200/month extra for life, she breaks even in 174 months (14.5 years). If she expects to live past age 73, working one more year is financially justified.
