How the APR Calculator Works
APR is the rate that equates the net loan proceeds (after fees) to the present value of all payments:
Loan Amount − Fees = Monthly Payment × [1 − (1+r_APR/12)^(−n)] ÷ (r_APR/12)
This equation is solved numerically (Newton-Raphson) for r_APR, then annualised: APR = r_APR × 12
Example: $30,000 loan at 6.5% for 5 years with $900 in fees
Monthly payment = $587 · Effective APR ≈ 7.03% (vs 6.5% stated rate)

APR Calculator Frequently Asked Questions
Why is APR higher than the stated interest rate?
APR includes the interest rate plus all upfront fees, spread across the loan term. Fees reduce the effective loan proceeds but don't reduce your payments, the same payments on a smaller net amount imply a higher true rate.
What fees are included in APR?
Typically: origination fees, discount points, mortgage broker fees, closing costs paid to the lender. Not always included: appraisal fees, title insurance, prepaid insurance/taxes. Regulations vary by loan type, always ask your lender for the APR disclosure.
How do I use APR to compare two loan offers?
Compare APRs directly. Loan A at 6.5% with $1,500 in fees may have a higher APR than Loan B at 6.75% with no fees, especially on a short term. APR levels the playing field by expressing the total cost as a single annual rate.
Does APR assume I hold the loan to full term?
Yes, APR calculations spread fees across the entire loan term. If you refinance or pay off early, the actual cost is higher because you paid fees for a shorter period. For loans you may pay off early, also calculate the cost at your expected actual term.
Is a lower APR always better?
Usually yes, but consider the cash flow. A loan with a slightly higher APR but lower monthly payments may suit you if cash flow is tight. Also compare total cost: a lower-rate loan with a longer term can cost more total interest than a higher-rate shorter-term loan.
Are the numbers I enter into this calculator saved or tracked?
No. Every calculation runs right inside your browser using local code. Your salary, debts, and loan numbers stay completely private. Nothing is ever saved or sent to any server.
How should I account for taxes, inflation, and unexpected fees?
Most formulas show baseline estimates. In real life, keep local taxes, inflation, and bank fees in mind so your budget matches your actual costs.
