Employer match calculator

Published August 16, 2026

A 50 percent match on the first 6 percent of pay gives 3 percent of salary when you defer 6 percent or more, and less if you defer less. On $80,000 that is $2,400 a year at a 6 percent deferral, and only $1,200 if you stop at 3 percent, leaving $1,200 unclaimed.

Employer match this year

$2,400.00

The full available match of $2,400.00 is captured. Invested for 30 years at 7 percent, the match stream grows to $243,994.20.

You put in this year: $4,800.00
Employer match this year: $2,400.00
Maximum match available: $2,400.00

Match stream after 30 years: $243,994.20

Annual salary

Gross pay the match is measured against.

You defer

Share of salary you put in. The match stops rising once this hits the cap.

Match rate

What the employer pays on each dollar inside the cap. 50 means fifty cents on the dollar.

Match cap

The slice of pay the match applies to. A 50 percent match on the first 6 percent caps at 3 percent of pay.

Years invested

How long the annual match is assumed to keep arriving and compounding.

Annual return

A constant rate, so two match schedules are comparable. Not a forecast.

The formula

M = S \times \min(d, c) \times m

$S$ is salary, $d$ the share of pay you defer, $c$ the cap the match applies to, and $m$ the match rate, all as decimals. Deferring past the cap still raises your own contribution and does not raise the match.

What the formula is actually matching

An employer match is a stated rate applied to a stated slice of pay, not a share of whatever you happen to put in. The common quote, a 50 percent match on the first 6 percent, means the plan pays fifty cents for each dollar you defer until your deferral hits 6 percent of pay, and nothing more after that.

On $80,000 of salary the cap is $0.06 \times 80000 = 4800$ of your own money. At a 50 percent match rate the plan then pays half of that, $2,400, which is 3 percent of pay. Defer 10 percent and you still get $2,400: the extra 4 percent is yours alone. Defer 3 percent and the plan matches half of 3 percent, $1,200, which is half the available match.

That leftover is the number this page exists to make visible. It is not a fee and it is not interest. It is pay the plan had already offered and that a lower deferral declined. The compound interest calculator is the next step if you want to watch a stream of those dollars grow; this page stops at naming how large the stream is.

Why deferring past the cap still changes the result

The match has a ceiling. Your own contribution does not. A 10 percent deferral on $80,000 is $8,000 of your money plus the same $2,400 of match, $10,400 combined. A 6 percent deferral is $4,800 plus $2,400, $7,200 combined. The match is identical and the totals are not, because the extra 4 percent is still going in.

What the cap changes is the return on the next dollar. Inside the cap, each dollar you defer brings fifty cents with it, a 50 percent instant return before any market does anything. Past the cap, the next dollar brings nothing extra from the employer. That is why the usual order of operations in a workplace plan is: defer enough to take the whole match, then look at the rest of the tax-advantaged picture, not the other way around.

The match is also not the same object as the contribution limit. The cap in the formula is a percent of your pay. The annual limit is a dollar figure set by statute, and it counts your deferral, not the match, in the United States. Hitting the match cap and hitting the annual limit are two different ceilings and they do not move together.

What a leftover match costs once it is invested

A match unclaimed this year is not only this year's dollars. If the same gap repeats, it is a missing deposit into a compounding stream. On the $80,000 salary, deferring 3 percent instead of 6 percent leaves $1,200 of match on the table each year. Paid in monthly and compounded at 7 percent for 30 years, that leftover stream grows to $121,997.10, the same figure the captured half of the match grows to, because the two halves are the same size.

That 7 percent is an illustration, not a forecast. A lower return shrinks the future value and a higher one raises it, and a real return sequence is uneven, so the future-value line on this calculator is the arithmetic of one constant rate. What does not depend on the rate is the first-year gap: $1,200 unclaimed is $1,200 unclaimed at every return, including zero.

Vesting sits outside the arithmetic. Some plans hand the match over as it is paid; some require years of service before it is yours to keep. The formula on this page counts the match as credited. Whether it would survive a job change is a plan-document question, not a formula one.

What this page is not doing

It is not choosing a deferral for you, and it is not modelling the tax treatment of the contribution. A traditional deferral cuts taxable income this year; a Roth deferral does not. The match, in a United States workplace plan, is typically pre-tax on the way in even when your own deferral is Roth. Those are tax facts, and they belong beside this calculation rather than inside it.

It is also a single-tier match. Some plans pay 100 percent of the first 3 percent and 50 percent of the next 2 percent. That is two applications of the same formula, not a different idea: run the first tier, run the second, add them. The calculator stays on one rate and one cap so the kink at the cap is visible rather than buried in a second slider.

For the household version of a required contribution, the savings goal calculator works backwards from a target. For the tax-deferred wrapper the match sits inside, see tax-advantaged accounts.

Worked examples

A 50 percent match on the first 6 percent, taken in full

Salary is $80,000. The plan matches 50 percent of the first 6 percent of pay. You defer 6 percent. What is the match this year, and what does that match stream grow to over 30 years at 7 percent, paid in monthly?

Your deferral: $80000 \times 0.06 = 4800$ , so $4,800.
The matched slice is the smaller of 6 percent and 6 percent, which is 6 percent. Match: $80000 \times 0.06 \times 0.50 = 2400$ , so $2,400.
Nothing is left on the table: the maximum match is the same $2,400, 100 percent captured.
Treat the $2,400 match as a monthly contribution for 30 years at 7 percent compounded monthly. The future-value annuity of that stream is $243,994.20.

The match is $2,400 this year, the full amount on offer. Invested monthly at 7 percent for 30 years, that stream reaches $243,994.20. Combined with your own $4,800, $7,200 goes in this year.

The same plan, stopping at 3 percent

Same $80,000 salary and the same 50 percent match on the first 6 percent. You defer only 3 percent. How much match is left unclaimed, and what does that leftover stream grow to over 30 years at 7 percent?

Your deferral: $80000 \times 0.03 = 2400$ , so $2,400.
The matched slice is now 3 percent, not 6. Match: $80000 \times 0.03 \times 0.50 = 1200$ , so $1,200.
The maximum match is still $2,400, so $1,200 is left on the table.
That leftover, paid monthly for 30 years at 7 percent compounded monthly, grows to $121,997.10.

The match this year is $1,200, half of the $2,400 on offer. Combined contributions are $3,600. The unclaimed half, invested on the same 30-year 7 percent path, grows to $121,997.10. That is the cost of stopping at 3 percent, measured as a missing compounding stream rather than as a single year's dollars.

Deferring past the cap

Same plan, same $80,000. You defer 10 percent. Does the match rise?

Your deferral: $80000 \times 0.10 = 8000$ , so $8,000.
The matched slice cannot exceed 6 percent, so the match is still $80000 \times 0.06 \times 0.50 = 2400$ , 100 percent of the cap.
Combined: $8000 + 2400 = 10400$ , so $10,400 goes in. The extra 4 percent of pay above the 6 percent case is yours alone.

The match stays at $2,400. Deferring past the cap raised your own contribution to $8,000 and left the employer line unchanged. Combined contributions are $10,400.

The mistake that costs the most

Reading '50 percent match' as 50 percent of salary, or as 50 percent of whatever you put in with no cap.

On $80,000, 50 percent of salary would be half the paycheck, which no ordinary match formula pays. 50 percent of a 10 percent deferral with no cap would be half of $8,000, which this plan also does not pay. The actual match is 50 percent of the first 6 percent, $2,400. The words 'on the first 6 percent' are the whole formula. Drop them and the number you get is not a rounding error, it is a different benefit.

Common questions

Does the match count toward the annual contribution limit?

In the United States, the elective-deferral limit counts what you put in, not the match. The match counts toward a higher combined limit. The two ceilings are different numbers and they are rewritten by statute, so read this year's figures from the plan, not from memory.

Is the match always 50 percent on 6 percent?

No. That is a common quote and it is the default on this calculator because it makes the cap visible. Plans also use 100 percent of the first 3 percent, 100 percent of the first 6 percent, or two tiers stacked. Enter the rate and cap your plan actually prints.

Should I always defer at least to the cap?

Inside the cap, the match is an instant return on the next dollar that no portfolio can copy. Whether that dollar is available, and whether a high-interest balance should be cleared first, is a household question this page does not answer. The arithmetic only names what the unclaimed match is worth.
