401k Calculator & Guide
Learn what a 401(k) match percentage means, how percentages such as 3%, 4%, 5% and 6% affect employer contributions, and how to calculate the match under a typical plan formula.
The match percentage tells you how much your employer contributes relative to the employee contribution that qualifies under the plan's matching formula.
A 50% match means the employer contributes 50 cents for each dollar of eligible employee contributions.
The plan can limit how much of your salary or employee contribution is considered when calculating the match.
The dollar amount you receive depends on your salary, contribution percentage and the plan's matching formula.
The examples below show the difference between the employer's match rate and the salary percentage used as the match limit.
The calculation starts with the amount of your contribution that qualifies under the plan's match limit.
The IRS uses a similar example to explain how a 50% matching rate interacts with a 5% salary limit. :contentReference[oaicite:2]{index=2}
Suppose the plan matches 50% of employee contributions up to 5% of eligible salary.
The first $4,000 of employee contributions can be used for this simplified matching calculation.
The employer match on the $4,000 matchable amount is:
The resulting employer contribution in this simplified example is $2,000.
Enter your salary, contribution percentage, employer match rate and salary match cap to estimate the employer contribution.

The following examples demonstrate how different match rates can produce different employer contributions.
| Plan Formula | Salary | Employee Contribution | Matchable Amount | Employer Match |
|---|---|---|---|---|
| 100% up to 3% | $80,000 | 5% | $2,400 | $2,400 |
| 50% up to 5% | $80,000 | 10% | $4,000 | $2,000 |
| 50% up to 6% | $80,000 | 10% | $4,800 | $2,400 |
| 100% up to 5% | $100,000 | 8% | $5,000 | $5,000 |
| 50% up to 8% | $100,000 | 10% | $8,000 | $4,000 |
These two numbers are often confused when employees read their 401(k) benefits information.
This describes how much the employer contributes relative to the employee contribution that qualifies for the match.
This describes the maximum amount of employee contributions or compensation that the employer will use when determining the match.
Employer matching contributions may be subject to a vesting schedule depending on the plan.
Your own employee contributions are generally 100% vested, along with associated earnings.
Employer matching contributions can vest over time depending on the plan and applicable rules.
Your employer's plan documents are the source to use when determining the actual matching formula.
