Move the slider and pick a term and APR to see an estimated fixed monthly payment. Lenders set the real rate, fees and term, so treat the result as a planning number.
| $2,000 over 12 months at | Payment (est.) | Total (est.) |
|---|---|---|
| 14.99% APR | $180.51/mo | $2,166.12 |
| 24.99% APR | $190.08/mo | $2,280.96 |

How to use the 4 pillar funding calculator
Enter the amount you want to borrow, an APR and a repayment term, and the 4 pillar funding calculator above shows an estimated monthly payment, total repayment and total interest for a fixed-rate personal loan.
Start with the personal loan amount you actually need, not a round number. If your mechanic quotes $1,380, try $1,500 and see whether the payment fits. Then enter an APR. If you have no offer yet, test three rates: a low one near 9%, a middle one near 19.99% and a high one near 29.99%. Lenders in personal-loan markets generally quote APRs from about 6% to 35.99%, and your credit profile will decide where you land.
Finally, choose a term. Lenders often quote terms of about 6 to 36 months for smaller personal loans. Move the term up and down to see how the payment and the total cost change in opposite directions.
How the monthly payment math works
A fixed-rate personal loan uses amortization, which spreads the balance over equal payments so each one covers that month's interest first and puts the rest toward principal, until the balance reaches zero on the final payment.
The calculator uses the standard amortization formula, written here in words:
- Divide the APR by 12 to get the monthly interest rate. At 24.99% APR, the monthly rate is about 2.0825%, or 0.020825.
- Add 1 to the monthly rate and raise the result to the power of the number of months. Call this the growth factor.
- Multiply the loan amount by the monthly rate and by the growth factor.
- Divide that result by the growth factor minus 1. The answer is the monthly payment.
Put another way: payment equals the amount borrowed, times the monthly rate, times the growth factor, divided by the growth factor minus one.
Early payments on a personal loan are mostly interest because the balance is at its highest. As the balance falls, the interest portion shrinks and more of each payment goes to principal. That is why paying extra early, when a lender allows it with no prepayment penalty, saves the most interest.
Worked payment examples at 24.99% APR
At 24.99% APR with a fixed rate and no fees, $2,000 over 12 months costs about $190.08 a month and $2,280.96 in total, an estimate that includes $280.96 of interest.
The table below shows more personal loan estimates at the same 24.99% APR. Each figure assumes a fixed rate, on-time payments and no fees.
| Amount | Term | Est. monthly payment | Est. total repaid |
|---|---|---|---|
| $1,000 | 6 months | $179.02 | $1,074.12 |
| $1,000 | 12 months | $95.04 | $1,140.48 |
| $1,500 | 12 months | $142.56 | $1,710.72 |
| $1,500 | 18 months | $100.78 | $1,814.04 |
| $2,000 | 24 months | $106.73 | $2,561.52 |
| $2,500 | 12 months | $237.60 | $2,851.20 |
| $2,500 | 24 months | $133.42 | $3,202.08 |
| $3,000 | 24 months | $160.10 | $3,842.40 |
| $4,000 | 36 months | $159.02 | $5,724.72 |
Two rows show how the same payment can buy very different loans. A $3,000 loan over 24 months and a $4,000 loan over 36 months both land near $160 a month, but the $4,000 loan costs about $1,724.72 in interest, compared with about $842.40 for the $3,000 loan, both estimates.
How APR and term change the total cost
APR sets how fast interest builds and the term sets how long it builds, so a lower APR or a shorter term each reduces the total cost of a personal loan, while a longer term lowers the monthly payment.
Here is the same $2,000 borrowed over 12 months at different APRs, as estimates:
| APR | Est. monthly payment | Est. total interest |
|---|---|---|
| 8.99% | $174.89 | $98.68 |
| 14.99% | $180.51 | $166.12 |
| 19.99% | $185.26 | $223.12 |
| 24.99% | $190.08 | $280.96 |
| 29.99% | $194.96 | $339.52 |
| 35.99% | $200.91 | $410.92 |
Moving from 35.99% to 14.99% APR saves about $20 a month and about $245 over the year on this loan. Changing the term has a larger effect on the total. At 24.99% APR, $2,000 over 12 months costs about $280.96 in interest, while 24 months costs about $561.52, roughly double, even though the payment drops from $190.08 to $106.73.
A practical approach is to pick the shortest term whose payment you can make comfortably every month, with room left for groceries, gas and a small cushion. See how lenders usually price loans on our rates page.
Estimates for each loan amount
Each amount page walks through payments, typical uses and lender expectations for one loan size, so you can check the calculator's estimate against a fuller guide for the amount you plan to request.
- A $1,000 loan guide for smaller repairs and bills.
- A $1,500 loan guide for car repairs and catch-up costs.
- A $2,000 loan guide for mid-size emergencies.
- A $2,500 loan guide for home system repairs.
- A $3,000 loan guide for debt consolidation and larger repairs.
- A $4,000 loan guide for bigger costs spread over longer terms.
Borrowers often run the calculator on two neighboring amounts, such as $2,000 and $2,500, to see whether the extra $500 is worth the higher payment. Before you request, review what lenders typically look for on our eligibility page.
Limits of calculator estimates
Calculator results are estimates for planning, not personal loan offers, because a lender sets your actual APR, fees, term and payment after reviewing your credit, income, debts, state and the loan amount you request.
Keep these limits in mind:
- Fees are not included. An origination fee deducted at funding reduces the cash you receive and raises the APR on the offer.
- Rates are not guaranteed. The APR you enter is a guess until a lender quotes one in writing.
- Payment timing varies. Some lenders use biweekly payments or a first payment date that adds a few days of interest.
- State rules differ. Minimum amounts, fee caps and available terms can vary by state.
- Rounding. Lenders may round each payment differently, so the final payment may differ by a few cents.
Use the calculator to set a payment ceiling before you look at offers. Many readers also check 4pillar funding guides and borrower comments before they request, and if a lender's offer comes in above your ceiling, you can decline it with no obligation. Compare every 4pillar funding offer on its APR, total repayment and fees in writing.
Quick answers
Frequently asked questions
Does the calculator include origination fees?
No. The calculator assumes a fixed rate and no fees, so it shows the cost of interest alone. If a lender deducts an origination fee, you will receive less than the amount borrowed, and the APR on the offer will be higher than the interest rate. Compare the APR and total repayment on the written offer.
Why does a longer term cost more if the monthly payment is lower?
Interest is charged on the remaining balance every month, so stretching repayment keeps a balance outstanding for longer. At 24.99% APR, $3,000 costs about $3,421.44 over 12 months but about $4,293.36 over 36 months, an estimate. The lower payment trades off against more total interest.
Will using the calculator affect my credit score?
No. The calculator runs in your browser and does not collect or share your information. A credit check only comes into play if you submit a request, and even then the first step may involve a soft credit check, which does not affect your score.
