What Is Imputed Interest?

Imputed interest is “imaginary interest.”

You don’t charge it, but tax rules still count it.

The IRS says:

If your loan rate is too low, you must still report interest income.

Think of it like this:

You gave a free loan, but the law says, “interest still exists.”

Imputed Interest Formula

Here is the simple formula used in most cases:

Imputed Interest = Loan Amount × (AFR − Stated Rate) × Time

Where:

• AFR = market interest rate from IRS
• Stated Rate = your loan interest rate
• Time = loan duration in years

If no interest is charged:

Imputed Interest = Loan Amount × AFR × Time
