Calculate Your Loan Per Diem Interest
Understanding Loan Per Diem Interest
When dealing with loans, especially mortgages or personal loans with daily interest accrual, understanding "per diem interest" is crucial. Per diem, Latin for "per day," refers to the amount of interest that accrues on your loan each day. This daily interest calculation becomes particularly important during specific financial events, such as paying off a loan early, refinancing, or closing on a property.
Why is Per Diem Interest Important?
Knowing your loan's per diem interest helps you in several ways:
- Accurate Payoffs: When you're ready to pay off a loan, the lender will provide a payoff amount. This amount changes daily because of the accruing interest. Understanding the per diem allows you to estimate the exact payoff amount on a future date.
- Refinancing Calculations: If you're refinancing, the new lender will need to know the precise payoff amount for your old loan. Per diem interest ensures this figure is correct, avoiding surprises at closing.
- Real Estate Transactions: In real estate, per diem interest is used to prorate interest between the seller and buyer, especially if the closing date doesn't align perfectly with the loan's payment cycle.
- Budgeting and Planning: For loans with daily interest, knowing the per diem helps you understand the true cost of delaying a payment or making an early payment.
How is Per Diem Interest Calculated Manually?
The calculation for per diem interest is straightforward. It generally involves your loan's principal balance, its annual interest rate, and the number of days for which you want to calculate the interest. The most common formula is:
Per Diem Interest = (Loan Amount × Annual Interest Rate) ÷ 365 days
If you need to calculate the interest for a specific number of days, you would then multiply this daily rate by that number of days:
Total Per Diem Interest = (Loan Amount × Annual Interest Rate ÷ 365) × Number of Days
It's important to note that the "Annual Interest Rate" must be converted to a decimal (e.g., 5% becomes 0.05) for the calculation. Some lenders might use 360 days for their calculations, but 365 is more common for consumer loans.

Important Considerations and Disclaimers
While this calculator provides a reliable estimate, always remember the following:
- Official Payoff Statements: For exact payoff amounts, always request an official payoff statement from your lender. This statement will include any additional fees, principal reductions, or specific calculation methods that might not be accounted for in a general calculator.
- Interest Calculation Methods: Different loans and lenders may use slightly different methodologies for calculating interest (e.g., simple interest, compound interest, 360-day vs. 365-day year). Our calculator uses the standard simple interest per 365-day year.
- Escrow Accounts: If your loan (like a mortgage) includes an escrow account for taxes and insurance, these components are separate from the interest calculation and won't be reflected in the per diem interest.
- Prepayment Penalties: Some loans may have prepayment penalties if you pay them off early. These are not included in the per diem interest calculation and should be factored into your overall payoff strategy.
