401(k) profit sharing formulas

There are several types of profit sharing formulas companies can utilize: pro-rata, flat-dollar, or new comparability.

Updated over a month ago

Profit sharing is a pre-tax contribution employers can make to their employees’ retirement accounts after the end of the year. There are several types of profit sharing formulas your company may want to utilize, depending on your business needs and situation: pro-rata, flat-dollar, or new comparability.

With a Guideline Core or Enterprise plan, you can utilize all 3 formulas. However, there is a fee for Core plans that wish to use new comparability profit-sharing.¹

Here’s how each formula works and calculation examples.

Pro-rata profit sharing formula

The pro-rata (also known as comp-to-comp) profit sharing formula takes a fixed contribution amount and allocates it to your employees in equal percentages based on their relative compensation. This formula is the default profit sharing method for Guideline 401(k) plans.

Pro-rata example:
Atmos Inc. wants to give a profit sharing contribution totaling $10,000. The amount of all eligible employee compensation is $200,000. In this case, each participant receives a contribution equal to 5% of their compensation.

Employee

Compensation

How It’s Calculated

Contribution (%)

Susan

$40,000

$40,000 * ($10,000 / 200,000)

$2,000 (5.0%)

Ian

$60,000

$60,000 * ($10,000 / 200,000)

$3,000 (5.0%)

Barbara

$100,000

$100,000 * ($10,000 / 200,000)

$5,000 (5.0%)

Flat-dollar profit sharing formula

The flat-dollar formula gives every employee the same contribution amount.

Flat-dollar example:
Atmos Inc. wants to give a profit sharing contribution totaling $10,000. Three employees share it equally, receiving $3,333 each.

Compensation

How It’s Calculated

Contribution (%)

Susan

$40,000

$10,000 / 3 (to each employee)

$3,333 (8.33%)

Ian

$60,000

$10,000 / 3 (to each employee)

$3,333 (5.55%)

Barbara

$100,000

$10,000 / 3 (to each employee)

$3,333 (3.33%)

New comparability profit sharing formula

New comparability profit sharing looks at factors such as age and compensation amount to provide more customized contributions. These calculations can be more complex and dynamic than those for other profit-sharing formulas.

New comparability profit sharing is available for Enterprise plans with a safe harbor employer contribution for the current year. Core plans interested in this profit sharing model can add this service for a fee by contacting Sponsor Support.
