How to use Loan Fee and Effective Rate Calculator

Enter loan proceeds and upfront fees paid from them.
Enter the equal monthly payment and payment count.
Review monthly yield, annualized rates and the cash-flow residual.

Example: Loan Fee and Effective Rate Calculator

Loan Fee and Effective Rate Calculator: Modeled effective annual yield: 0%.

You add

Stated loan amount: 1200 Upfront fees withheld from proceeds: 0 Fixed monthly payment: 100 Number of monthly payments: 12

You get

Modeled effective annual yield: 0%. Measure Value Net proceeds 1200.00 Monthly implied yield (%) 0 Nominal annualized yield, 12r (%) 0 Effective annual yield (%) 0 Total payments 1200.00 Payments minus net proceeds 0.00 Present-value residual 0 This is a modeled cash-flow yield, not statutory APR or a lender disclosure. One positive advance less entered upfront fees is compared with equal positive payments at month end. It excludes irregular dates, financed fees, balloon payments and other charges. Legal APR and finance-charge rules depend on the jurisdiction and transaction. Net proceeds | 1200.00 Monthly implied yield (%) | 0 Nominal annualized yield, 12r (%) | 0

Options

Net proceeds: The model starts from the stated loan amount minus the fees withheld upfront. Those proceeds must remain positive.
Payment sequence: Enter equal positive payments at the end of each month. Irregular dates, extra advances and balloon payments need a different model.

Supported inputs and limits

Positive net advance followed by equal positive end-of-month payments for 1–1,200 months. Whole-cent amounts up to 1 trillion. A bounded monotonic solver finds the monthly borrowing yield, including negative yields, and reports annualizations and its residual. No irregular dates, multiple advances, balloon payments or legal fee classification. Modeled yield is not statutory APR.

Modeled borrowing yield is not a statutory APR

The solver finds a monthly rate that discounts the entered repayments to the net proceeds. Nominal and effective annualizations describe that same mathematical rate using different conventions. Fee classification and required legal disclosures vary; this page does not determine them. Review the reported residual as part of the numerical result.

Questions about Loan Fee and Effective Rate Calculator

Is this the APR a lender must disclose?

No. Statutory APR depends on applicable rules, included charges and timing. This page solves the stated cash-flow model only.

Why can the yield be negative?

If the modeled repayments are worth less than the net advance at zero interest, the corresponding cash-flow yield is negative.

What does the residual show?

It shows the difference between the modeled present value of repayments and net proceeds at the solved rate.
