SIMPLE IRA Employer Match Calculator
A SIMPLE IRA requires the employer to contribute, using one of two formulas. Enter your headcount, average pay, and expected participation to compare the annual cost of the 3% dollar-for-dollar match against the 2% nonelective contribution.

Estimates only, not tax advice. The 3% match is paid only for employees who defer, so its cost tracks participation. The 2% nonelective is paid for every eligible employee regardless of whether they contribute. Actual cost depends on each employee's pay and deferral. Confirm with your CPA.
How the two employer formulas work
Each plan year the employer picks one of two contribution formulas. The 3% match is dollar-for-dollar on what each employee defers, up to 3% of that employee's compensation. Because it only applies to employees who actually contribute, its total cost tracks participation: if half your team defers, you pay roughly half of the full-participation cost.
The 2% nonelective is a flat 2% of compensation for every eligible employee, paid whether or not they defer. Its cost is predictable and does not move with participation. The calculator estimates both so you can see which is cheaper for your team, and it flags the lower of the two.
A worked example
Take ten employees earning an average of $50,000, the calculator's starting inputs. At full participation the 3% match costs $15,000, at 75% participation about $11,250, and at 50% about $7,500. The 2% nonelective is $10,000 no matter what. The crossover sits at roughly two thirds participation: above it the flat 2% is cheaper, below it the match wins, which is why the participation slider matters more than any other input.
What to keep in mind
Real cost will differ from the estimate because the match is capped per employee at 3% of that employee's own compensation, not the team average. If your higher earners are the ones who defer, the cost at a given participation rate runs above the estimate. The nonelective is also calculated on pay only up to the annual compensation limit.
Frequently asked questions
How much does an employer pay for a SIMPLE IRA match?
Under the standard formula the employer matches employee deferrals dollar-for-dollar up to 3% of each employee's compensation. Because it only applies to employees who defer, the total cost depends on how many people participate and how much they earn.
Is the 3% match or the 2% nonelective cheaper?
It depends on participation. The 3% match is paid only for employees who contribute, so at low participation it costs less than the 2% nonelective, which is paid for every eligible employee regardless. The break-even is two thirds: once the payroll of participating employees passes two thirds of total eligible payroll, the 3% match becomes the more expensive formula.
Does everyone have to get the employer contribution?
Under the 2% nonelective, yes. Every eligible employee receives 2% of compensation whether or not they defer. Under the 3% match, only employees who defer receive the employer money, and only up to what they actually contribute.
Can the employer switch formulas each year?
The employer chooses the formula each plan year and must tell employees before the election period. There are limits on reducing the 3% match in a given year, so confirm the rules with a plan administrator or CPA before changing.

Methodology and sources
The cost model follows IRAPilot's plan estimator. The 3% option is a dollar-for-dollar match on employee deferrals up to 3% of compensation, paid only for employees who defer, and the calculator ranges it by participation. The 2% nonelective option pays 2% of compensation for every eligible employee regardless of participation.
