About the Social Security Calculator
The single biggest lever in Social Security planning is your claiming age. Claim at 62 (24 months before FRA 67), your monthly benefit is cut to roughly 70% of the FRA figure — a permanent haircut. Wait to 70 and it grows to about 124% of FRA, alla lifetime of bigger checks from the same earnings record.
This tool shows monthly benefits and lifetime totals at each major claiming age, so a “62-claim, plan-sized need” can be measured honestly against delayed claiming.
The formula behind it
SSA-style adjustment factors (approximate):
At 62 (FRA 67): ≈ 70% of FRA benefit • At FRA: 100% • At 70: ≈ 124%The SSA rules state a linear reduction of 5/9% of the benefit per month for the first 36 months early and 5/12% per month beyond that (for FRA 67 retirement at 62 that is −30%); delayed-retirement credits add 8%/yr past FRA to a maximum at 70, where they have the greatest effect. FRA varies between 65 and 67 depending on birth year.
Worked example
Defaults — FRA benefit of $2,200/month with FRA of 67:
- At 62: roughly $1,540/month (70%).
- At 67 (FRA): the full $2,200.
- At 70: roughly $2,728/month (124%).
Takeaway: From that scenario, lifetime totals to age 85 differ materially: claiming at 62 collects ~$425k by 85; waiting until 70 collects ~$491k — worth every month of patience on average lifespans (and precisely where spousal and survivor strategy lives).
What moves the result
- Claiming age — the largest lever most retirees control.
- Full Retirement Age (FRA) — between 65 and 67 depending on birth year (for 1960+: it is 67).
- Marital status and survivor options — spousal and survivor benefits ride on both records and claiming strategy.
- Bread-and-butter pre-retirement earnings — each high-earnings year replaces a zero or lower year up to 35 best-earnings-year computations.
Practical tips
- If you have reliable longevity risk in your family, delaying is a longevity annuity: it converts a one-time input to an inflation-indexed, government-backed income stream.
- If you plan on taking at 62, note the earnings test: claiming before FRA and continuing to work can temporarily withhold benefit dollars.
- For couples, coordinate claiming: the survivor benefit is a function of the higher-earning spouse’s record — protecting that side of the plan matters for at least one of you.
- Your own case: create an account at ssa.gov and download your actual earnings record — estimated FRA benefit beats any web calculator.
- For spousal and divorcing scenarios, run both claiming timelines through the tool separately before choosing one.
Frequently asked questions
How much is cut by claiming at 62?
When FRA is 67, claiming at 62 gives roughly 70% of your FRA benefit — a 30% permanent reduction (SSA percentages are exact, down to the month; a rounding matters here).
What does delaying until 70 earn?
Delayed retirement credits add roughly 8% of your benefit per year past FRA — at FRA 67, that peaks at about 124% of the FRA benefit.
Do benefits continue to grow with inflation after claiming?
Yes — an annual COLA (Cost-of-Living Adjustment) protects against inflation; it compounds the value for delayed claimers. Note the COLA rate varies by year.
