Does retiring early reduce your Social Security? How the 35-year formula works

Yes, retiring early usually lowers your Social Security a little, because your benefit is based on your highest 35 years of earnings and any year you don't work counts as a zero. But the formula counts your first dollars of earnings the most, so stopping work 10 or even 20 years early often trims your check by far less than the share of years you skipped.

This guide walks through how the formula actually works, with the 2026 figures (and the 2027 ones SSA has just announced), a made-up example of stopping at 45 or 55, and how to check your own record. It's about how big your benefit is. When you start it is a separate choice, covered in When to claim Social Security.

This is general education, not financial or tax advice. Your own record and SSA's rules decide your benefit. Check your numbers in your my Social Security account or call SSA at 1-800-772-1213 before you make a decision based on them.

Figures checked October 27, 2026 against SSA.gov: the PIA formula and bend-point tables, the benefit-amounts explainer, the contribution and benefit base table, the quarter-of-coverage table, the latest COLA page and the Quick Calculator FAQ. SSA announced the 2027 figures in October 2026.

How Social Security works out your benefit, step by step

It looks complicated, but there are only four steps.

1. You need 40 credits to qualify at all

You earn Social Security credits by working and paying Social Security tax, up to four a year. In 2026, you get one credit for each $1,890 of earnings, so $7,560 in a year earns all four. In 2027, it's $1,970 per credit, or $7,880 for four (SSA).

Most people need 40 credits for a retirement benefit (SSA), so about 10 years of work. Credits only decide whether you qualify. Having 80 credits instead of 40 doesn't raise your check; your earnings do.

2. Each year's earnings are adjusted for wage growth

A $30,000 salary in 1995 was worth a lot more, relative to everyone else's pay, than $30,000 today. So SSA "indexes" your past earnings: it scales each year up by how much average wages have grown since then (SSA).

The indexing runs up to the year you turn 60. Earnings from 60 on count at face value. For someone first eligible in 2027 (turning 62 that year), SSA indexes to the 2025 national average wage index, $72,800.33, and counts 2025 and later earnings as they are.

This matters a lot for early retirees. If you stop work at 45, your earnings from your 20s, 30s and early 40s keep being scaled up with wage growth until you turn 60. They don't shrink in value while you wait.

3. The highest 35 years are averaged, zeros included

SSA takes your 35 highest indexed years, adds them up, and divides by 420 (the number of months in 35 years). The result, rounded down to the dollar, is your average indexed monthly earnings, or AIME (SSA).

If you have only 23 years of earnings, SSA still divides by 420. The 12 missing years count as zeros. That's the part people mean when they say retiring early "costs" Social Security.

Only earnings up to each year's taxable maximum count, the same cap that limits Social Security tax: $184,500 for 2026 and $192,300 for 2027 (SSA).

4. The bend-point formula turns the average into a monthly benefit

Your average then runs through a three-tier formula that gives you your primary insurance amount (PIA), the monthly benefit you'd get at full retirement age (SSA):

Source: SSA, [PIA formula bend points](https://www.ssa.gov/oact/cola/bendpoints.html). The bend points rise each year with average wages.

The year you turn 62 fixes which bend points apply to you, and your PIA gets each year's cost-of-living increase from that year on, whether or not you've claimed (SSA). The increase for 2027 is 3.6% (SSA).

Claiming before or after full retirement age (67 for anyone born in 1960 or later) then shrinks or grows that amount. Social Security at 62, 67 or 70 covers that part.

Why zeros hurt less than you'd think

Look at the tiers again. The first $1,286 of your monthly average is replaced at 90%, the next stretch at 32%. Most people's average lands in the middle slice. That means a zero year mostly removes dollars that were only being paid at 32%, while the 90% slice stays full.

So the benefit falls more slowly than the years do. Fewer working years, and a bigger share of what's left is in the generous first slice.

A worked example: Riley

Riley is made up for this guide. Riley started working full time at 22 and earned the equivalent of $65,000 a year in today's wages every year. We'll use the 2026 bend points and SSA's rounding, and keep everything in today's dollars.

Our arithmetic, using SSA's 2026 PIA formula. Real records are messier: pay changes over the years, and future bend points will be higher. Treat this as a sketch, not an estimate.

Stopping at 55 instead of 57 costs Riley about $99 a month. Stopping at 45, with 12 zero years in the average, costs about $595 a month, roughly 24%, even though Riley skipped about a third of the 35 years.

Each extra year of Riley's pay replaces a zero and adds about $155 to the monthly average, which adds about $50 a month to the full benefit (32% of $155). Once Riley has 35 years, another year only helps if it beats Riley's lowest year.

Who feels zeros the most

The cushioning works best when your average sits in the middle slice. If your average is low enough to sit entirely in the first slice, every zero year cuts your benefit in close to direct proportion, because it's all being paid at 90%. And if you had 35 strong years already, stopping costs you nothing at all.

What this means for different early-retirement paths

• Stopping completely at 45 or 50. You'll likely have zeros. The example above is a fair picture: a noticeable cut, but much smaller than the share of years you missed.
• Coast FIRE or barista FIRE. Part-time pay replaces zeros, but slowly. A year of $20,000 instead of a zero adds about $48 to the monthly average, or roughly $15 a month to the full benefit in the middle slice. It helps; it's rarely the main reason to work. Coast FIRE vs barista FIRE covers those paths.
• A career break or mini-retirement. A year or two off in your 30s often doesn't land in your top 35 at all if you work into your late 50s. How to take a mini-retirement has more.
• Years at home with kids. Those are zeros on your own record. A spousal benefit, based on your partner's record, doesn't depend on your own years at all. See spousal Social Security benefits and the stay-at-home parent's retirement.
• Self-employment. Net self-employment earnings go on your record like wages and earn credits, and you pay self-employment tax on them. Side income and your taxes covers the tax side.
• Work that didn't pay into Social Security. Years in some state and local government jobs with their own pension don't appear on your Social Security record. The Windfall Elimination Provision, which used to reduce benefits for people with those pensions, ended for benefits from January 2024 (SSA). FIRE on a public servant salary goes further.

Starting later isn't starting too late

If you're in your 40s or 50s and worried about gaps, here's the good news in the formula: each year you work now can replace a zero or a low year from long ago, and a higher-paying year late in your career can push out a weak one from your 20s. Working until 62 or beyond often fills more of the 35 than people expect. Behind on retirement savings puts this together with the other levers.

Check your own record

1. Open a free [my Social Security](https://www.ssa.gov/myaccount/) account. It shows your earnings for every year and estimates at different claiming ages.
2. Scan your earnings record for gaps or mistakes. A year that's missing or too low counts against you the same as a real zero. Your Statement explains how to report an error (SSA).
3. Count your years. How many years do you have, and how many more will you work? If it's under 35, the difference will be zeros.
4. Check what the estimate assumes. SSA's Quick Calculator assumes you'll keep having earnings until you start benefits unless you enter an earlier retirement date, and SSA notes your benefit will generally be lower the earlier you stop (SSA). If you plan to stop at 50, run the numbers with a stop date of 50.
5. Then think about claiming age. The Social Security calculator shows your check at every age from 62 to 70.

Common questions

How is Social Security calculated?

Social Security adjusts each year of your earnings for wage growth, takes your highest 35 years, and averages them into a monthly figure called your average indexed monthly earnings. It then pays 90% of the first slice of that average, 32% of the middle slice and 15% of anything above. For people turning 62 in 2026, the slices break at $1,286 and $7,749 a month. The result is your full benefit at full retirement age, which is then reduced if you claim earlier or increased if you wait.

Does retiring early lower my Social Security?

Usually a little, if it leaves you with fewer than 35 years of earnings, because the missing years count as zero. But the formula counts your first dollars of earnings the most, so the cut is smaller than the share of years you missed. In our example, 23 years of work earns about 76% of the 35-year benefit. If you already have 35 good years, stopping early doesn't lower it at all.

What happens if I don't have 35 years of work?

SSA still divides your total by 35 years, so the missing years count as zeros in your average. You still qualify for a benefit as long as you have 40 credits, which is about 10 years of work.

Does working past 35 years increase my Social Security?

Only if the new year's earnings, after adjusting for wage growth, are higher than your lowest year in the top 35. Then the new year replaces the old one and your benefit is recalculated. SSA reviews working beneficiaries' records every year and raises the benefit automatically when a new year counts.

How many credits do I need for Social Security, and how much is a credit in 2026?

Most people need 40 credits for retirement benefits, and you can earn up to four a year. In 2026, you earn one credit for each $1,890 of earnings, so $7,560 earns all four. In 2027, it's $1,970 per credit.

Does my Social Security estimate assume I keep working?

SSA's Quick Calculator assumes you'll keep having earnings until you start benefits unless you enter an earlier retirement date. If you plan to stop work early, look at what your estimate assumes, and use a stop date so the estimate includes your zero years.
