Calculate the true total cost of any loan including interest, origination fees, closing costs, and all charges. See the real price of borrowing beyond the interest rate.
The interest rate on a loan tells only part of the story. Origination fees, closing costs, insurance premiums, application fees, and other charges can add thousands to your actual borrowing cost. Two loans with the same interest rate can have very different total costs once fees are included.
The Total Cost of Borrowing Calculator gives you a unified, all-in view of what a loan really costs. Enter the principal, rate, term, and all associated fees to see the complete picture — total interest paid, total fees, cost per dollar borrowed, and effective annual cost.
This calculator works for any loan type — mortgage, personal loan, auto loan, student loan, or business loan. Use it to compare offers from different lenders on a true apples-to-apples basis. Many borrowers focus on the monthly payment alone, but the real measure of a loan cost includes all interest, fees, and charges over its full term. This calculator reveals the complete picture so you know exactly what you are agreeing to pay.
Lenders advertise interest rates but often bury fees in the fine print. An origination fee of 3% on a $30,000 loan adds $900 upfront. Monthly insurance premiums, annual fees, and processing charges compound the cost further. This calculator aggregates every cost line item so you can see the real price tag and compare lenders honestly.
Total cost = Total interest + Upfront fees + (Monthly fees × months) + (Annual fees × years). Cost per dollar = Total cost / Principal. Effective annual cost = Total cost / Years. Monthly payment = P × r(1+r)^n / ((1+r)^n − 1).
Result: $7,968 total cost ($6,018 interest + $1,950 fees)
A $30,000 loan at 7.5% for 60 months has a $601.35/month payment and $6,018 in total interest. Add a $900 origination fee, $50 application fee, and $25/month insurance ($1,500 over 60 months), and the true total cost is $7,968. That is $0.266 per dollar borrowed, or $1,594/year in borrowing costs.
Beyond interest, common hidden costs include origination fees (1-6% of the loan), mortgage insurance (PMI at 0.5-1% annually), GAP insurance on auto loans, annual account maintenance fees, and credit insurance premiums. On a $200,000 mortgage, PMI alone can cost $1,000-$2,000 per year until you reach 20% equity.
Extending a loan term from 48 to 72 months lowers your monthly payment but can increase total interest by 40-60%. A $25,000 auto loan at 6% costs $4,799 in interest over 48 months but $7,316 over 72 months — an extra $2,517 for the convenience of a lower payment.
When comparing loan offers, normalize everything to total cost. Lender A may offer 6.5% with no fees, while Lender B offers 5.9% with a 2% origination fee. On a $30,000 loan for 60 months, Lender A's total cost is $5,168 while Lender B's total cost is $5,149 — nearly identical despite the rate difference.
Armed with total cost calculations, you can negotiate more effectively. If a lender offers a low rate but high fees, show them the total cost comparison and ask them to reduce fees. Lenders often have flexibility on origination fees and processing charges.
Any expense directly tied to obtaining and maintaining the loan: interest, origination fees, closing costs, application fees, appraisal fees, credit report fees, monthly insurance premiums (PMI, GAP), annual fees, prepayment penalties, and late fees. This calculator lets you include all of these.
APR expresses the annual cost of borrowing as a percentage, including certain fees. Total cost is the actual dollar amount you pay above the principal. Both are useful — APR for comparing rates, total cost for understanding the real dollar impact on your budget.
Fees. A loan at 7% with a 3% origination fee costs more than a loan at 7% with no fees. Additionally, loan term matters — a 7% loan for 5 years costs less total interest than a 7% loan for 7 years, even though the monthly payment is higher.
Cost per dollar borrowed divides total borrowing cost by the principal. If you borrow $30,000 and the total cost is $7,968, you pay $0.266 for every dollar borrowed. This metric makes it easy to compare loans of different sizes.
Usually, but not always. A lower total cost with a much higher monthly payment may strain your cash flow. Consider total cost alongside monthly payment affordability, flexibility (prepayment options), and your time horizon (will you keep the loan to term?).
No. APR includes interest, origination fees, and some closing costs, but excludes optional fees like late fees, prepayment penalties, and some third-party fees. The total cost of borrowing calculator captures all fees you input, giving a more complete picture.
