Designing an Employer 401(k) Match Formula That Fits Your Budget
A 401(k) match is an employer contribution that rises with the amount an employee defers from pay, which makes the formula a budget commitment before it is a benefits feature. This guide is for owners and CFOs at growing businesses, including professional services, healthcare, construction, manufacturing, hospitality, and restaurant employers, who are adding a match or tuning one. It covers common formulas, fixed versus discretionary designs, how cost scales with participation, the IRS limits that apply, student loan matching, and where payroll fits.
What does a typical employer match look like?
There is no single typical match. A formula combines a match rate (the cents the employer adds per dollar an employee defers) with a cap (the percentage of pay beyond which deferrals earn no additional match). The IRS offers a plain example in its 401(k) plan overview, a plan in which the employer contributes 50 cents for each dollar employees defer. Match formulas generally take one of a few shapes.
* Match dollar-for-dollar up to 3% or 4% of pay. The maximum cost is 3% or 4% of each participant’s pay, earned by deferring the same percentage.
* Match 50% of the first 6% of pay. The maximum cost is 3% of pay, and an employee must defer 6% to earn all of it.
* Use a tiered formula, such as 100% of the first 3% of pay plus 50% of the next 2%. The maximum cost is 4% of pay, reached when an employee defers 5%.
The maximum cost per participant is the number to carry into the budget.
Should the match be fixed or discretionary?
A fixed match follows a formula written into the plan document, and the employer must apply it as written. The IRS states that when a plan provides for matching contributions, the employer must follow the plan’s match formula. A discretionary match leaves the decision to the employer each year, including whether to contribute and at what rate, within what the plan document permits.
A fixed match gives employees a predictable benefit and gives the budget a firm commitment. A discretionary match gives an owner room to adjust in a slow year, at the cost of that predictability. The right choice depends on how steady your cash flow is.
How does match cost scale with participation?
In a simple model, match cost equals the total pay of eligible employees, multiplied by the share of those employees who defer enough to earn the match, multiplied by the match percentage they earn. Participation drives the total, so budget against the ceiling at full participation and treat anything lower as room under it.
Hypothetical example, for illustration only. An employer has 20 eligible employees, each paid $60,000, for $1,200,000 in total pay. Every participating employee defers enough to earn the full match.
Participating employees
50% of the first 6% of pay
100% of the first 4% of pay
10 of 20
$18,000
$24,000
15 of 20
$27,000
$36,000
20 of 20
$36,000
$48,000
For each fully deferring participant, the first formula costs $1,800 and the second costs $2,400. The tiered formula above also costs $2,400 per employee who defers 5% or more, but it pays less to employees who defer less. An employee deferring 4% earns a 3.5% match under the tiered formula and a 4% match under the second. The example ignores pay growth, turnover, and vesting.
To build your own estimate, multiply the total pay of your eligible employees by the formula’s maximum match percentage, then by the participation rate you plan for.
Which IRS limits cap what the plan can accept?
Two IRS limits bear directly on a match. Both figures below are stated as of October 6, 2026, for tax year 2026.
The first is the overall limit on annual additions. Per the IRS, the total added to one participant’s account in a year, counting employee salary deferrals (excluding catch-up contributions), employer matching contributions, employer nonelective contributions, and allocated forfeitures, cannot exceed the lesser of 100% of the participant’s compensation or $72,000 for 2026. See the IRS page on 401(k) and profit-sharing plan contribution limits and IRS Notice 2025-67.
The second is the compensation cap. A plan can take into account no more than $360,000 of an employee’s pay in 2026 when determining employer and employee contributions, and the IRS explains that a plan uses only compensation up to the cap when it applies a match formula. At the cap, a match worth 4% of pay tops out at $14,400.
Both amounts are subject to annual cost-of-living adjustments, so confirm the current figures each plan year. For the employees in the example above, the match sits far below both limits. The limits matter most for employees whose pay is high enough that deferrals plus employer contributions approach $72,000.
How does vesting affect a match?
Vesting is the point at which matching dollars become the employee’s to keep. In a traditional 401(k) plan, a vesting schedule may apply to the match. Under Internal Revenue Code section 411(a)(2)(B), the IRS lists two alternative minimum schedules for employer contributions, including matches. With three-year cliff vesting, the match is 100% vested once the employee completes three years of service. With six-year graded vesting, the match vests gradually and reaches 100% at six years. A plan may vest faster, including immediately, and an employee’s own deferrals are always fully vested.
A safe harbor 401(k) is a separate design with its own required match formulas and vesting rules, so the schedules above describe traditional plans. The tiered formula in this guide is one of the safe harbor match formulas the IRS describes.
Can an employer match student loan payments?
Yes. Section 110 of the SECURE 2.0 Act of 2022 lets a 401(k) plan make matching contributions on account of an employee’s qualified student loan payments, for plan years beginning after December 31, 2023. IRS Notice 2024-63 provides the guidance. A plan that adds the feature follows these rules.
* Add the feature to the plan document, since it is optional.
* Match loan payments at the same rate the plan matches deferrals.
* Offer the student loan match to every employee who is eligible for the regular match.
* Vest the student loan match the same way as the regular match.
* Collect an annual certification from the employee, which the plan may rely on.
* Count only payments on a qualified education loan the employee took out for education costs of the employee, a spouse, or a dependent, up to an annual cap on the amount that counts.
