Borrowing Cost Snapshot

Interest rate and APR are not always the same

Upfront finance charges can increase the annualized cost even when the loan's stated interest rate stays unchanged.

Stated loan amount $0 The principal amount used to calculate the scheduled loan payment.
Net proceeds $0 Estimated amount received after the entered upfront charges.
Stated interest rate 0% The note rate used to calculate principal and interest payments.
Estimated APR 0% Annualized rate implied by the net proceeds and scheduled payments.

Understanding APR

What is annual percentage rate?

APR is an annualized measure intended to express the cost of borrowing. It can differ from the stated interest rate when certain finance charges are included in the calculation.

Interest rate

The stated interest rate is used to calculate interest on the outstanding loan principal. It directly affects the scheduled principal-and-interest payment.

Why fees can increase APR

Suppose a borrower signs a $20,000 loan but receives less than $20,000 after an upfront finance charge is deducted. If the scheduled payments are still based on the full $20,000 principal, the annualized borrowing cost is higher than the note rate alone suggests.

APR can help with comparisons

APR can provide additional context when two loan offers have different combinations of interest rates and qualifying finance charges. A loan with the lower note rate does not necessarily have the lower APR.

Official APR calculations can differ

Not every fee is necessarily included in a lender's disclosed APR. Which charges count can depend on the type of credit, transaction and applicable disclosure requirements.

APR Calculator FAQ

Frequently asked questions

What is APR?

APR stands for annual percentage rate. It is an annualized measure of borrowing cost that can reflect both interest and certain finance charges.

Is APR the same as the interest rate?

Not necessarily. The interest rate is the rate used to calculate interest on the principal balance. APR may also reflect certain eligible finance charges and can therefore be higher than the stated interest rate.

Why does an origination fee increase APR?

If a fee reduces the amount of money the borrower actually receives while the scheduled payment remains based on the full loan amount, the implied annualized borrowing cost increases.

Will the monthly payment change when I add an upfront fee here?

Not in this calculator. The payment is calculated from the stated loan amount and note interest rate. The entered upfront charges reduce the estimated net proceeds and therefore affect the APR estimate.

Can two loans have the same interest rate but different APRs?

Yes. If the loans have different qualifying finance charges or different repayment structures, their APRs can differ even when the stated interest rates are the same.

Can a lower interest rate have a higher APR?

It is possible when the lower-rate loan carries sufficiently larger finance charges. Comparing both the stated rate and APR can provide additional context.

Is this the same APR my lender will disclose?

Not necessarily. This calculator estimates APR from the loan amount, payment stream and finance charges entered. Official disclosures can depend on transaction-specific rules regarding which charges are included.

Why might my lender's APR differ slightly?

Differences can result from payment timing, fee treatment, rounding, irregular first-payment periods and the specific methodology required for the transaction.
