Imputed interest expenses are usually higher than actual interest expenses because they are calculated based on the market rate of interest, which may be higher than the actual interest rate paid on a loan.

In these cases, the imputed interest expense is calculated to reflect the true economic cost of borrowing, which may be higher than the actual interest paid. Additionally, imputed interest expenses are often used for tax purposes to ensure that the appropriate amount of interest income is reported and taxed. **
