The Social Security calculator gives a simplified, educational estimate of how your monthly Social Security retirement benefit changes depending on the age at which you claim it — from as early as 62 to as late as 70. It's designed to illustrate the tradeoff between claiming early and claiming late as clearly as possible, not to replace your official SSA benefit statement.
The real SSA benefit formula uses your highest 35 years of earnings, each indexed for national average wage growth, to compute your Average Indexed Monthly Earnings (AIME). This calculator simplifies that dramatically: it uses your current annual salary (capped at an illustrative Social Security taxable wage base) divided by 12 as a stand-in for AIME. It then applies a simplified version of the SSA's bend-point formula — 90% of the first slice of AIME, 32% of the next slice, and 15% of the remainder — using approximate 2024 bend points, to estimate your Primary Insurance Amount (PIA), which is your benefit at Full Retirement Age. Finally, it adjusts that PIA up or down based on your planned claiming age relative to your FRA, using the SSA's standard early-reduction and delayed-credit rules.
This tool is useful for anyone in their working years starting to think about retirement timing, people within a decade of age 62 weighing an early-claim decision, and people who simply want to see, in rough numbers, how much claiming age can move their monthly benefit. It pairs well with NeftCal's 401(k) Calculator and Retirement Calculator for a fuller picture of retirement income, since Social Security is normally only one piece of that plan.
The decision of when to claim Social Security is one of the highest-stakes, hardest-to-reverse choices in retirement planning — claiming at 62 instead of 70 can permanently reduce your monthly benefit by roughly 30% or more, and delaying to 70 can increase it by roughly 24% versus Full Retirement Age. Seeing the 62 / FRA / 70 comparison side by side, even with simplified numbers, helps illustrate the size of that tradeoff so you can dig into your real numbers — via your ssa.gov statement — with more context.
Illustrative bend points and claiming-age adjustments, simplified from actual SSA rules
The formula replaces a higher percentage of lower earnings than higher earnings — this is intentional, and makes Social Security proportionally more valuable to lower earners.
Full Retirement Age is 67 for anyone born in 1960 or later, stepping down to 66 for those born 1943–1954, with a gradual monthly increase for birth years 1955–1959 in between.
From your birth year to a claiming-age comparison in under a minute
Your birth year determines your Full Retirement Age (FRA) — the age at which SSA rules entitle you to 100% of your calculated benefit, with no early-claiming reduction or delayed-credit increase.
This is used as a simplified stand-in for your Average Indexed Monthly Earnings (AIME). The real SSA formula uses your actual 35 highest-earning years, each indexed for national average wage growth.

The calculator shows your estimated Full Retirement Age, your Primary Insurance Amount (PIA), and a side-by-side comparison of your estimated monthly benefit at 62, FRA, and 70, plus a bar chart and claiming-age table.
Using the calculator's own default scenario — a $80,000 salary, born 1985
Suppose you're 40 years old, born in 1985, earning $80,000 a year, and comparing what your estimated monthly Social Security benefit would look like at claiming ages 62, Full Retirement Age (67), and 70.
Explanation: In this scenario, waiting from 62 to 70 raises the monthly benefit by about 77% ($1,991.09 to $3,527.07) — a permanent difference of over $1,500 a month for the rest of the person's life. The "break-even age" — the point at which cumulative benefits from delaying catch up to and surpass cumulative benefits from claiming early — typically falls in the late 70s to early 80s in scenarios like this, which is why life expectancy and health are such important factors in the claiming decision, alongside the raw dollar amounts.
What your claiming-age comparison actually tells you
There's no single "good" or "bad" claiming age — but the size of the gap between your 62, FRA, and 70 estimates is a useful signal for how much weight to put on the decision.
| Situation | General Read | Typical Consideration |
|---|---|---|
| Healthy, other income available, can wait | Delaying toward 70 usually maximizes lifetime and survivor benefit | Locks in the largest permanent monthly check |
| Still working near FRA, no urgent cash need | Claiming at or near FRA is a reasonable middle ground | Avoids the early-claiming reduction and the earnings test |
| Health concerns, limited savings, need income now | Claiming at 62 may be the practical choice despite the permanent reduction | Provides income sooner when it's needed most |
For long-life-expectancy households: delaying claiming, especially for the higher earner in a couple, tends to maximize lifetime and survivor benefits — the "insurance" value of a larger guaranteed check compounds the longer you live.
For those needing income sooner: claiming at 62 isn't a mistake if it's what allows you to retire, cover expenses, or preserve other savings — the permanent reduction is a real tradeoff, not a penalty for a "wrong" choice.
Risk considerations: this calculator doesn't model spousal/survivor benefits, taxation of benefits, continuing to work while claiming early, or annual cost-of-living adjustments — all of which can meaningfully change the real numbers. Use this as a starting point, not a final answer.

| Feature | Claim at 62 | Claim at FRA (67) | Claim at 70 |
|---|---|---|---|

| Monthly benefit (example) | $1,991.09 | $2,844.41 | $3,527.07 |
