  1. Number of payments

    n=30×12=360n = 30 \times 12 = 360
  2. Amount financed

    AF=300,000.00−6,000.00=294,000.00A_F = 300{,}000.00 - 6{,}000.00 = 294{,}000.00

    Fees paid at closing or deducted from the proceeds are prepaid finance charges and come off the amount financed (12 CFR 1026.18(b)).

  3. Payment each period

    P=300,000.00×0.0054166666671−(1+0.005416666667)−360=1,896.20P = \frac{300{,}000.00 \times 0.005416666667}{1 - (1 + 0.005416666667)^{-360}} = 1{,}896.20
  4. Solve the Appendix J equation for the rate per period

    294,000.00=1,896.20 1−(1+i)−360i⇒i=0.005579430791294{,}000.00 = 1{,}896.20\,\frac{1-(1+i)^{-360}}{i} \Rightarrow i = 0.005579430791

    No closed form exists; the rate is bracketed by bisection and refined by Newton's method until the two sides agree to 28 decimal places.

  5. معدل النسبة السنوية (⁨APR⁩)

    APR=12×0.005579430791=6.695%\text{APR} = 12 \times 0.005579430791 = 6.695\%

    12 CFR 1026 Appendix J (b)(1): the rate per unit-period times the unit-periods in a year.

  6. Effective annual rate

    (1+0.005579430791)12−1=6.905%(1 + 0.005579430791)^{12} - 1 = 6.905\%
  7. Finance charge

    682,633.47−294,000.00=388,633.47682{,}633.47 - 294{,}000.00 = 388{,}633.47

    Total of payments minus the amount financed: all interest plus the fees.

حول APR calculator

The APR is the yearly rate at which the loan payments are worth exactly the money you actually receive, the amount financed. Fees charged for the credit, such as origination fees and points, lower the amount financed when you pay them at closing, or raise the payments when they are added to the loan, so the APR comes out above the interest rate. The calculator solves for that rate numerically, as the actuarial method in Regulation Z, Appendix J, prescribes, and multiplies the rate per payment period by the periods in a year.

With the defaults, $300,000 at 6.5% for 30 years costs $1,896.20 a month. With $6,000 of fees paid upfront, the borrower receives $294,000, and the APR is 6.695%; the effective annual rate is 6.905%.

The APR assumes the loan runs to the end of its term with every payment on time. Paid off early, the fees are spread over fewer years and the true cost is higher.

الأسئلة

What is the difference between APR and interest rate?

The interest rate sets the payment; the APR also counts fees charged for the credit and expresses the total cost as a yearly rate. A $100,000 loan at 6% for 10 years costs $1,110.21 a month; with $2,500 of upfront fees the borrower nets $97,500 and the APR is 6.563%. Without fees the APR equals the rate.

How is APR calculated?

Find the rate per payment period at which the present value of all payments equals the amount financed, then multiply by the number of periods in a year. Regulation Z's Appendix J example: $5,000 repaid in 24 monthly payments of $230 gives a monthly rate of 0.80714%, so the APR is 9.69%. There is no closed formula, so the rate is found by iteration.

Which fees are included in the APR?

Charges that are part of the finance charge under Regulation Z: points, loan and finder's fees, and premiums for insurance that protects the lender against default, such as mortgage insurance (12 CFR 1026.4(b)). Charges of a type you would pay in a cash deal are left out, and on real-estate loans so are bona fide title, appraisal, credit-report and document fees (1026.4(c)(7)).

What is the difference between APR and effective annual rate?

The APR is the rate per period times the periods in a year, with no compounding; the effective annual rate compounds it: (1 + APR ÷ 12)^12 − 1 for monthly payments. A 6.695% APR on a monthly loan is an effective 6.905%. US disclosures use the APR; the effective rate is what the loan costs over a full year of compounding.

How accurate does a lender's APR have to be?

Within 1/8 of a percentage point of the true APR for a regular loan, and within 1/4 point for irregular ones with multiple advances or uneven payments, under 12 CFR 1026.22(a). A disclosed APR of 6.75% on the default loan, whose true APR is 6.695%, is inside the tolerance; 6.85% is not.
