Social Security break-even calculator
Show a client when waiting to claim pays off. Enter their year of birth and the benefit at full retirement age, pick two or three claiming ages from 62 to 70, and see the monthly benefit at each, the running totals and the age at which the later claim catches up. Built on SSA's own reduction and delayed credit rules.
An estimate, not tax or investment advice. It covers the worker's own retirement benefit only: no spousal or survivor benefits, no earnings test, no taxes and no Medicare premiums. Check the figures against the client's Social Security statement before acting.
How the break-even age is worked out
Everything starts from the primary insurance amount (PIA): the monthly benefit at full retirement age. Claiming earlier or later changes it by a fixed percentage that SSA sets in its rules.
- Before full retirement age, the PIA is cut by 5/9 of 1% for each of the first 36 months early and 5/12 of 1% for each month beyond 36. With a full retirement age of 67, starting at 62 is 60 months early and pays 70% of the PIA.
- After full retirement age, each month without a benefit earns a delayed retirement credit of 2/3 of 1% (8% a year) for people born in 1943 or later. Credits stop at 70, so with a full retirement age of 67 the most is 124% of the PIA.
- The running total for each claiming age adds up one monthly benefit for every month from that age on.
- The break-even ageis the first month in which the later claim's running total equals or passes the earlier one's. A client who lives beyond it collects more in total by waiting; one who dies before it would have collected more by claiming early.
Claiming is one decision among many in a retirement plan, and it depends on facts that change: health, a spouse's record, other income. Keeping those facts current for every client is the work Marloo, the AI CRM for financial advisors, is built for.
Full retirement age and benefit at 62 and 70, by year of birth
From SSA's full retirement age table and its reduction and delayed credit rules. Someone born on January 1 uses the row for the year before. Percentages are of the PIA, rounded to one decimal the way SSA's charts print them.
| Year of birth | Full retirement age | Months early at 62 | At 62 | At 70 |
|---|---|---|---|---|
| 1943 to 1954 | 66 | 48 | 75% | 132% |
| 1955 | 66 and 2 months | 50 | 74.2% | 130.7% |
| 1956 | 66 and 4 months | 52 | 73.3% | 129.3% |
| 1957 | 66 and 6 months | 54 | 72.5% | 128% |
| 1958 | 66 and 8 months | 56 | 71.7% | 126.7% |
| 1959 | 66 and 10 months | 58 | 70.8% | 125.3% |
| 1960 or later | 67 | 60 | 70% | 124% |
Methodology and sources
The rules come from SSA's Program Operations Manual System (POMS) and its regulations in 20 CFR Part 404, and each one was checked against both. The calculator is tested against every cell of SSA's published percent-of-PIA charts for starting ages from 62 to 70, and against the worked examples in the regulations. Monthly amounts use SSA's fractions and round down to the dime, as SSA does.
- SSA POMS RS 00615.003, Full Retirement Age (effective May 21, 2004; reviewed November 7, 2026). Full retirement age by date of birth, from 65 and 2 months for people born from January 2, 1938 to 67 for people born on January 2, 1960 or later. Each row runs from January 2 to January 1.
- 20 CFR 404.409, What is full retirement age? (eCFR, current as of November 5, 2026). The same full retirement age table in SSA’s regulations, used to cross-check the POMS chart.
- 20 CFR 404.102, Definitions (eCFR, current as of November 5, 2026). You reach an age on the day before your birthday. POMS RS 00615.004 (effective September 16, 2002) applies the same rule month by month.
- SSA POMS RS 00615.101, Reduced RIB (effective March 29, 2017; reviewed November 7, 2026). The early retirement reduction: 5/9 of 1% for each of the first 36 months before full retirement age and 5/12 of 1% for each month after that, applied as fractions and rounded down to the dime.
- 20 CFR 404.410, How does SSA reduce my benefits when my entitlement begins before full retirement age? (eCFR, current as of November 5, 2026). The same reduction rule in the regulations, with a worked example the calculator is tested against.
- SSA POMS RS 00615.105, Estimating Reduced Retirement Benefits (effective January 9, 2004; reviewed November 7, 2026). SSA’s chart of the percent of the PIA payable at each starting age from 62 to full retirement age. Every cell for people born after January 1, 1955 is checked against the calculator.
- SSA POMS RS 00615.690 and RS 00615.692, Delayed Retirement Credits (effective December 6, 2023 and November 14, 2014; reviewed November 7, 2026). One credit for each month from full retirement age to the month before age 70 that a benefit is not paid; 2/3 of 1% a month (8% a year) for people born after January 1, 1943; the credit is rounded down to the dime.
- 20 CFR 404.313, Delayed retirement credits (eCFR, current as of November 5, 2026). The same credit rates in the regulations, and when SSA adds credits: those earned before the year you claim are in the first benefit; those earned in the year you claim are added the next January, or at 70.
- SSA POMS RS 00615.693, Estimating the Effect of Delayed Retirement Credits (effective November 14, 2014; reviewed November 7, 2026). SSA’s chart of the percent of the PIA payable at each starting age from 67 to 70. Every cell is checked against the calculator.
- 20 CFR 404.311, When does my entitlement to old-age benefits begin and end? (eCFR, current as of November 5, 2026). Before full retirement age, benefits start with a month in which you meet every requirement throughout the month, so you must be 62 for the whole month.
Simplifications
- Ages are counted in whole months, the way SSA counts them: a person reaches an age on the day before their birthday. Each benefit is counted in the month it is for, not the day it is paid.
- Before full retirement age, a benefit can only start in a month the client is 62 for the whole month, so for most people the earliest start is 62 and 1 month. The calculator still allows 62 and 0 months, which is the starting point SSA's charts use.
- Delayed credits earned in the calendar year of claiming are added by SSA the following January (or at 70). The calculator applies them from the first month, so the first few payments may be slightly lower in practice.
- Nominal dollars by default, with no discounting and no taxes. The optional COLA is an assumption you set, not a forecast, and it applies the same rate every year from 63.
- The amount SSA pays can be slightly lower: any Medicare premium is deducted and the payment is rounded down to a whole dollar. The calculator shows the benefit before that.
What it does not cover
- Spousal, divorced spouse and survivor benefits, and how one spouse's claiming age changes the other's.
- The retirement earnings test for anyone working while claiming before full retirement age.
- Income tax on benefits, Medicare premiums, and the time value of money.
- Disability benefits, government pension offsets, and anyone born before January 2, 1938.
Social Security claiming questions advisors get asked
What is the Social Security break-even age?
It is the age at which the total benefits from claiming later catch up with the total from claiming earlier. Claiming early pays more checks; claiming later pays bigger ones. For someone with a full retirement age of 67, claiming at 70 instead of 62 catches up at about 80 and 4 months in nominal dollars. A client who lives past the break-even age collects more in total by waiting.
How much is Social Security reduced at 62?
The benefit is cut by 5/9 of 1% for each of the first 36 months before full retirement age and 5/12 of 1% for each month after that. For anyone born in 1960 or later, full retirement age is 67, so starting at 62 is 60 months early: a 30% cut, leaving 70% of the primary insurance amount (PIA).
How much does waiting until 70 add?
For people born in 1943 or later, each month a benefit is not taken after full retirement age earns a delayed retirement credit of 2/3 of 1%, or 8% a year. Credits stop at 70. With a full retirement age of 67 that is 36 credits, so the benefit at 70 is 124% of the PIA.
What is my full retirement age?
It depends on the year of birth: 66 for people born from 1943 to 1954, rising by 2 months a year for 1955 to 1959, and 67 for people born in 1960 or later. Someone born on January 1 uses the year before, because SSA treats people as reaching an age on the day before their birthday.
Is there any reason to wait past 70?
Not for a bigger retirement benefit. Delayed retirement credits stop at 70, so the monthly amount does not grow after that apart from cost-of-living adjustments. That is why the calculator stops at 70.
Does the break-even age tell a client when to claim?
No. It shows when waiting pays off in total dollars, which is one input. Health and life expectancy, a spouse’s benefits and survivor benefits, taxes, other income, and whether the client is still working all matter, and this calculator does not model them.
