APR is the yearly cost of a loan including interest plus certain fees. It is usually a little higher than the interest rate, it helps you compare similar offers on equal terms, and it can understate cost if you repay early.
Quick answers
What is APR?
APR (Annual Percentage Rate) is the yearly cost of a loan as a percentage — the interest rate plus certain fees. It lets you compare similar loans on equal terms and usually sits a little above the note rate.
Why is my APR higher than my interest rate?
Because APR counts fees, not just interest. Upfront fees shrink the cash you actually receive and financed fees grow the balance you pay interest on — both push the yearly cost above the note rate.
Is the lowest APR always the cheapest loan?
Only if you keep it to the end. APR spreads upfront fees over the full term, so for a short hold a low-fee loan can beat a lower-APR one with heavy fees — check the Early Payoff tab too.
Will this match my lender’s APR?
It’s a close estimate from standard amortization, ideal for comparing offers. A lender’s official APR can differ a little because fee inclusion, rounding, and payment timing follow disclosure rules — so treat this as a guide, not a disclosure.
How to use this APR calculator
Pick a mode. Choose General APR, Mortgage APR, Compare Offers, or Early Payoff using the tabs at the top.

Classify the fees. Enter financed and upfront fees (and, in advanced mode, itemise each fee as financed, upfront, or excluded from APR).
Read the APR and the gap. See the real APR, how far it sits above the note rate, the fee impact, and the cost stack of principal, interest, and fees.
Compare and export. Compare offers or model an early payoff, then download the 10-sheet Excel report built from your inputs.
The APR formula
Payment
PMT = P × r(1+r)ⁿ / ((1+r)ⁿ − 1)
P is the financed balance, r the periodic note rate, n the number of payments. At 0% it is P / n.
APR (solved numerically)
net proceeds = Σ payment / (1 + a)ᵏ
a is the periodic APR rate; APR = a × payments per year. Net proceeds = loan − upfront finance charges.
Fee treatment
financed → in balance · upfront → reduces proceeds
Excluded fees are shown but left out of APR unless reclassified.
APR vs APY
APR is nominal; EAR = (1 + a)ᵖ − 1
APR is the comparison figure; the effective annual rate is shown only as support.
A practical guide to APR
What APR means
APR — the Annual Percentage Rate — is a single number that estimates the yearly cost of a loan including both interest and certain fees. It exists because of truth-in-lending rules: lenders must disclose APR so borrowers can compare offers on a common basis rather than being misled by a low headline rate attached to high fees.
In this calculator, APR is the annual rate at which the present value of your scheduled payments equals the net amount you actually receive after upfront finance charges. When there are no fees, the APR equals the interest rate; every fee that counts as a finance charge nudges it higher.
APR vs interest rate
The interest rate (note rate) applies only to the principal — it is what generates your interest each period. APR is wider: it reflects the rate plus lender fees that are part of the cost of credit, so it is a better single measure of what a loan costs. The CFPB describes APR as the cost of credit expressed as a yearly rate, which is generally higher than the interest rate because it includes those charges.
A practical rule: use the interest rate to compute your monthly payment, and the APR to compare two loans. Two loans can share a rate but differ on APR because one charges more fees.
Real APR with fees
Fees are what separate APR from the note rate. Upfront fees are paid at closing and reduce the net proceeds you receive, so you effectively borrow less for the same payments — which raises the APR. Financed fees are rolled into the loan balance, so you pay interest on them across the amortization schedule, and your payment rises — which also raises the APR.
Because APR captures both effects, it is the most honest comparison of two similar offers — say, two car loans or two personal loans. The wider the gap between APR and the note rate, the more the fees are costing you.
Loaned fees vs upfront fees
A loaned (financed) fee is added to the amount you borrow: it does not come out of pocket today, but you pay interest on it for the whole term. An upfront fee is paid in cash at closing: no interest, but it reduces the money you walk away with. For the same dollar amount, an upfront fee usually pushes APR slightly higher than a financed one, because it hits you immediately rather than being spread out.
This tool lets you classify each fee as financed, upfront, or excluded. Excluded fees (often appraisal, title, taxes, and prepaid insurance) are shown for budgeting but left out of APR, because whether they belong in APR depends on the loan type and local rules.
Mortgage APR explained
Mortgage APR uses the same engine but adds the charges specific to a home mortgage: discount and origination points, lender fees, and PMI. Points are quoted as a percent of the loan (one point = 1%) and are an upfront finance charge, so they raise APR. PMI, where required, is generally treated as a finance charge for the period it applies, so including it lifts the APR too.
Crucially, mortgage APR is not your total cost of homeownership. It does not include property tax, homeowners insurance, HOA dues, or maintenance, and many third-party closing costs are excluded. Treat mortgage APR as a way to compare loan offers, not as your monthly housing budget.
Points and APR
Discount points are an upfront payment to lower your interest rate; origination points are an upfront lender charge. Both are finance charges, so they raise APR. The trade-off is that points lower your payment, so whether they pay off depends on how long you keep the loan: divide the points cost by the monthly saving to get a rough break-even in months.
A low rate bought with heavy points can show a low payment but a higher APR and a long break-even — so paying points only makes sense if you will hold the loan well past that point. Enter the rate you would get without points to estimate the break-even on the Mortgage tab.
PMI and APR
Private mortgage insurance (PMI) protects the lender when your down payment is under about 20%. Because it is a cost of getting the credit, PMI is generally included in mortgage APR for the months it is charged — which this calculator assumes lasts until the balance reaches 78% of the home’s value, the common automatic-cancellation point.
PMI is not the same as homeowners insurance, and it is not part of your loan principal. We show PMI as a monthly add-on and a total-monthly-with-PMI figure, and let you toggle whether to include it in APR, because PMI duration and treatment can vary.
APR vs APY / EAR
APR is a nominal rate: it is the periodic rate times the number of periods per year. APY (annual percentage yield) and EAR (effective annual rate) go further and account for compounding within the year, so they are a little higher than APR for the same periodic rate. Lenders disclose APR for borrowing; banks quote APY for savings.
We display APR as the headline and show the effective annual rate only as supporting context. When comparing loans, compare APRs; do not mix an APR from one quote with an APY from another.
Why APR can mislead on early payoff
APR assumes you keep the loan for its full term and spreads upfront fees evenly across every month. If you repay early, those fees are absorbed over fewer months, so your true annualized cost is higher than the APR implied. This is why a loan with the lowest APR is not always the cheapest if you plan to refinance, sell, or pay off quickly.
The Early Payoff tab shows the effective cost of holding the loan only to your expected payoff month. When upfront fees are high and the holding period is short, that effective cost can sit well above the headline APR.
How to compare two offers
Put both offers on the same loan amount and term, then look at three numbers: APR, total cost if held to maturity, and total cost if paid off at your expected month. For a full-term hold, the lower APR usually wins. For a short hold, the offer with lower upfront fees can win even at a higher rate.
The Compare Offers tab computes all three and highlights the lowest in each — under your entered assumptions, not as a recommendation. The headline takeaway: the lowest APR is not always the lowest cost if you repay early.
Worked examples
1. Personal loan with fees
A $20,000 loan at a 6.5% note rate over 60 months, with $500 of upfront fees, has a monthly payment of about $391. Because the $500 reduces the net proceeds to $19,500, the real APR is roughly 7.56% — about 1.06 points above the note rate, a high fee impact.
2. Mortgage with points
A $400,000 home with $80,000 down (a $320,000 loan) at 6.0% over 30 years, with 1 discount point (~$3,200) plus about $2,400 of lender fees, has a monthly principal & interest of about $1,919 and a mortgage APR near 6.15%. The points and fees lift the APR above the rate; property tax and insurance are not included.
3. Early payoff
Take the same $20,000 loan with $800 of upfront fees: its full-term APR is about 8.2%. But if you repay at month 18 of 60, those fees are absorbed over far fewer months, so the effective cost rises to roughly 9.8% — the same fees, compressed. That is why a low APR is not always the cheapest if you do not keep the loan.
4. Personal loan in India (INR)
A ₹10,00,000 (₹10 lakh) personal loan at an 11% note rate over 60 months, with a ₹15,000 processing fee deducted upfront, has a monthly payment of about ₹21,742. Because the fee reduces the net amount you receive to ₹9,85,000, the real APR works out to roughly 11.66% — about 0.66 points above the 11% note rate, a moderate fee impact. Switch the calculator’s currency to INR to reproduce these figures.
Assumptions & limitations
This calculator models a fixed-rate amortized loan with regular payments and solves APR numerically. It assumes no missed or late payments, no variable-rate changes, and no balloon payment unless you enter one. Fee treatment follows your classification, and PMI (where entered) is assumed to apply until the balance reaches 78% of the home’s value.
Not included by default: property tax, homeowners insurance, prepayment penalties, variable-rate changes, and third-party charges you classify as excluded. A lender’s official APR may differ because fee inclusion depends on loan type, jurisdiction, and disclosure rules. Use this to compare offers; rely on the lender’s disclosure for exact figures.
Frequently asked questions
Should I compare loans by interest rate or APR?
Use the interest rate to work out the monthly payment, and the APR to compare offers — it folds in the lender fees that count as finance charges, so it reflects more of the true cost. If a loan has no fees the two are essentially equal; the more fees, the wider the gap. Just do not compare one lender’s APR against another lender’s plain interest rate.
What fees are included in APR — and which are excluded?
Generally lender finance charges — origination fees, discount and origination points, processing and underwriting fees, and PMI while it is required — are included. Third-party charges that are not a condition of the loan, such as appraisal, title, taxes, and prepaid insurance, are often excluded. The exact list depends on the loan type and your jurisdiction, so this calculator lets you classify each fee as financed, upfront, or excluded.
Are mortgage points included in APR?
Yes. Discount points and origination points are upfront finance charges, so they are included in mortgage APR and lift it above the note rate. Points lower your rate and payment, so whether they pay off depends on how long you keep the loan — enter the rate you would get without points to estimate the break-even.
Does APR include PMI?
For mortgages, PMI is generally treated as a finance charge and included in APR for the period it is required. This calculator assumes PMI lasts until the balance reaches 78% of the home’s value and lets you toggle whether to include it. PMI is separate from homeowners insurance and is not part of your loan principal.
Does APR include property taxes and homeowners insurance?
Usually not. Property taxes, homeowners insurance, HOA dues, and many prepaid third-party charges are typically excluded, which is why a mortgage APR is not the same as your total monthly housing cost. This tool shows those excluded costs separately and only counts them in APR if you choose to.
What is the difference between a financed fee and an upfront fee?
A financed fee is added to the amount you borrow — no cash today, but you pay interest on it for the whole term. An upfront fee is paid at closing — no interest, but it reduces the money you actually receive. For the same dollar amount an upfront fee usually pushes APR slightly higher, because it hits you immediately rather than being spread out.
Why can APR be misleading if I pay off early?
APR assumes you keep the loan for its full term and spreads upfront fees evenly across every month. If you repay early — refinance, sell, or pay it off — those same fees are absorbed over fewer months, so your real annualized cost is higher than the APR implied. The Early Payoff tab shows that effective cost for your expected payoff month.
What is the difference between APR and APY?
APR is a nominal annual rate — the periodic rate times the number of periods per year — the way lenders disclose borrowing cost. APY (or EAR, the effective annual rate) accounts for compounding within the year and is slightly higher. APR is the figure to compare loans with; this tool shows the effective annual rate only as supporting context.
How do I compare two loan offers?
Use the Compare Offers tab: put both offers on the same amount and term, then look at three numbers — APR, total cost over the full term, and total cost if you repay at your expected month. For a full-term hold the lower APR usually wins; for a short hold the offer with lower upfront fees can win even at a higher rate. The tool highlights the lowest in each under your assumptions, not as a recommendation.
Does APR change with the loan term or payment frequency?
Yes, indirectly. For the same fees, a longer term spreads those fees over more payments, so the APR sits closer to the note rate; a shorter term concentrates them and widens the gap. Payment frequency and compounding affect how the periodic rate is annualized, so changing them can nudge the APR even when the note rate is unchanged.
Is APR a regulated, standardized figure?
In the US, the Truth in Lending Act (Regulation Z) requires lenders to disclose APR and defines which charges count as finance charges, which is why APR exists as a common way to compare credit. The exact rules — and which fees are included — vary by loan type and country, so this calculator lets you classify each fee rather than assuming a single standard. Always rely on the lender’s official disclosure for the binding figure.
