Capitalized commissions

ASC 606 commission amortization calculator

Under US GAAP, sales commissions that are incremental costs of obtaining a contract are generally capitalized and expensed over time instead of all at once. This calculator lays out a straight-line schedule by fiscal year so you can see what hits the income statement and what stays on the balance sheet.

Asset

The incremental cost of obtaining the contract that you capitalize.

The period over which the related goods or services are expected to transfer.

Timing

1 = first month of the fiscal year.

  • • Renewal commissions commensurate with the initial one usually point to amortizing the initial commission over the initial contract term, and each renewal commission over its own renewal term.

What ASC 340-40 asks for

ASC 606 governs revenue; the cost side sits in ASC 340-40. Costs that an entity would not have incurred if the contract had not been obtained, such as a commission paid on signature, are incremental costs of obtaining a contract. When the entity expects to recover them, they are recognized as an asset and amortized on a systematic basis consistent with the transfer of the related goods or services.

A practical expedient allows those costs to be expensed when incurred if the amortization period would be one year or less. Salaries and costs incurred whether or not the contract is won are not incremental.

How the schedule is built

Monthly expense = capitalized amount ÷ amortization months

Months in FY1 = 13 − start month (capped at the period)

FYn expense = cumulative amount through FYn − cumulative amount through FYn−1

Cumulative amounts are rounded to the cent before taking differences, so the fiscal years always add up exactly to the capitalized amount. The remaining asset at the end of FY1 is the amount not yet expensed.

Choosing the amortization period

The period should reflect the goods or services the commission relates to. If renewals earn a commission commensurate with the initial one, the initial commission is commonly amortized over the initial contract. If not, the period often extends to cover anticipated renewals. The renewal question in the form only adjusts the guidance; you decide the months.

Not accounting advice. Policies, impairment testing and disclosures should be confirmed with your auditors. To model the commission itself, start with the SaaS commission calculator or the commission calculator.

Frequently asked questions

Does every commission have to be capitalized?

Only incremental costs of obtaining a contract that the entity expects to recover. Commissions with an amortization period of one year or less may be expensed as incurred under the practical expedient, if the entity elects it.

Why straight-line?

It is the simplest systematic pattern and a common one when services transfer evenly over the contract. If your services transfer unevenly, the pattern of amortization should follow that transfer instead.

What happens if the customer churns early?

The remaining asset may need to be assessed for impairment or written off. This calculator assumes the contract runs its full period.
