Loan Comparison Calculator
Compare two loan offers side by side in seconds. Enter the amount, APR, and term for each loan to see the exact difference in monthly payment, total interest, and total cost.
A loan comparison calculator lets you see exactly what two competing offers cost — not just the monthly payment, but total interest and total cost over the full term. According to LendingTree's January 2026 data, personal loan APRs range from 11.81% for excellent-credit borrowers to 28.50% for poor-credit applicants — a spread that can mean thousands of dollars in extra interest on the same loan amount.
bolt Quick Answer
To compare two loan offers, enter both into this calculator with each lender's loan amount, APR, and term. The tool instantly shows monthly payment, total interest, and total cost side by side, and identifies which loan saves more money. A 1% APR difference on a $20,000 48-month loan costs $416 extra in total interest — real numbers you can act on.

Why Compare Loans Before You Borrow?
See the True Cost
Monthly payment comparisons hide the real picture. This calculator shows total interest and total cost so you know exactly what each offer really costs over time.
Save Hundreds or More
Shopping at least 3 lenders saves the average borrower 0.5–1.5% APR (CFPB, 2024). On a $25,000 loan, that's $600–$1,800 in your pocket — not the lender's.

Why Comparing Loans by Total Cost Matters More Than Monthly Payment
Most borrowers instinctively focus on the monthly payment — it's the number that hits your bank account every month and the one lenders promote in their advertising. But the monthly payment alone is a misleading metric because it says nothing about how long you'll be paying or how much interest accumulates over that time.
Consider two offers on a $15,000 loan: Loan A at 8% APR for 48 months produces a monthly payment of $366 and total interest of $2,568. Loan B at 12% APR for 60 months produces a monthly payment of $333 — $33 less per month — but total interest of $4,980. Loan B looks cheaper month to month but costs $2,412 more over its life. The monthly payment comparison actively misleads you in this scenario.
Total cost — the sum of every payment made — is the only number that fully reflects what a loan will take from you. This calculator shows total cost for both loans simultaneously so you can make an informed decision rather than one based on the most advertised figure.
How a 1% APR Difference Adds Up Over Time
A single percentage point may sound trivial, but compounded monthly over years it becomes a substantial sum. The table below shows the total interest cost difference that a 1% APR difference produces at three loan amounts and two common loan terms.
| Loan Amount | Term | Interest at 7% | Interest at 8% | Difference |
|---|---|---|---|---|
| $10,000 | 36 mo | $1,110 | $1,282 | $172 |
| $10,000 | 60 mo | $1,880 | $2,165 | $285 |
| $20,000 | 48 mo | $2,975 | $3,391 | $416 |
| $20,000 | 60 mo | $3,761 | $4,332 | $571 |
| $50,000 | 60 mo | $9,402 | $10,830 | $1,428 |
| $50,000 | 84 mo | $13,375 | $15,442 | $2,067 |
Calculated using standard amortization formula. All figures are total interest paid over the full loan term.
The impact scales with both loan size and term length. A 1% difference on a $50,000 84-month loan produces over $2,000 in extra interest — and this is just a one-point difference. In practice, the APR spread between the best and worst offers a borrower receives can be 4–6 points. At a 6% spread on a $25,000 60-month loan, that's over $4,000 in total interest difference — roughly equal to the cost of a modest vacation or three months of car payments.
What to Look For Beyond the APR When Comparing Loans
APR is the most important single number, but a complete loan comparison includes several additional factors that can meaningfully affect your total cost and flexibility:
- chevron_right Origination fees — charged upfront, typically 1–8% of the loan amount. Some lenders deduct these from the disbursement (you receive less than you borrowed); others add them to the loan balance. APR should capture this, but confirm it does.
- chevron_right Prepayment penalties — some lenders charge a fee if you pay off the loan early. If you plan to pay ahead of schedule, a loan with a prepayment penalty may end up costing more despite a lower APR.
- chevron_right Payment flexibility — some lenders allow you to defer a payment or change your due date once per year. If cash flow is variable, this feature has real value even if the APR is slightly higher.
- chevron_right Variable vs. fixed rates — if Loan B has a variable rate, today's lower rate could increase over the loan term. Always compare fixed-rate offers to each other, and factor in risk when comparing a fixed to a variable offer.
- chevron_right Disbursement speed — if you need funds quickly for an emergency or time-sensitive purchase, a lender that disburses in 1 business day may be worth a slightly higher APR compared to a lender that takes 5–7 days.
Loan Comparison Calculator FAQs
What's the best way to compare two loan offers? expand_more
The most reliable way to compare two loan offers is to look at total cost — the sum of all payments over the life of each loan — rather than just the monthly payment. Enter both loans into this calculator with the same loan amount, each lender's quoted APR, and each loan's term. The calculator shows monthly payment, total interest, and total cost side by side so you can see the true difference.
Should I choose the loan with the lower monthly payment or lower total cost? expand_more
It depends on your priorities. A lower monthly payment gives you more cash flow each month but usually means a longer term and more total interest paid. A lower total cost saves money over time but requires a higher monthly payment. If you can comfortably afford the higher payment, the lower total cost option is almost always the better financial choice. Use this calculator to see the exact dollar difference.
What fees should I consider when comparing loans? expand_more
When comparing loans, always account for origination fees (typically 1–8% of the loan amount), prepayment penalties, late payment fees, and any required insurance products. APR already incorporates most standard fees into the rate, which is why APR is always the more accurate comparison metric than the stated interest rate. Ask each lender for a full fee schedule and the APR before making a decision.
How do I compare loans with different amounts? expand_more
To compare loans with different amounts, focus on the APR and total cost relative to the amount borrowed. A larger loan at a lower APR may cost less in total than a smaller loan at a higher APR depending on the term. This calculator lets you input different loan amounts for Loan A and Loan B so you can model the exact scenario you're evaluating and see a direct dollar comparison.
Is APR or interest rate more important when comparing loans? expand_more
APR (Annual Percentage Rate) is always more important for comparison than the stated interest rate. APR includes the interest rate plus fees such as origination charges, discount points, and other lender costs, expressed as a yearly rate. Two loans with identical interest rates can have very different APRs if their fees differ. Always compare APR to APR — never interest rate to APR.
