Personal Loan Calculator — What Will Your Monthly Payment Be?
Table of Contents
A personal loan payment depends on three numbers: the loan amount, the interest rate (APR), and the loan term. Enter these three inputs into the free loan calculator and you get your exact monthly payment, total interest paid over the life of the loan, and a full amortization schedule showing exactly how each payment breaks down between principal and interest. No signup, no credit pull, no email required.
This guide explains how personal loan payments are calculated, how interest rate and term affect your total cost, and what questions to ask before taking a personal loan. The calculator at the link above handles all the math.
How Personal Loan Monthly Payments Are Calculated
Personal loan payments are calculated using the standard amortizing loan formula. Each payment covers both interest and principal, with the ratio shifting over time: early payments are mostly interest, later payments are mostly principal.
The formula:
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
Where: P = loan amount, r = monthly interest rate (annual APR ÷ 12), n = number of monthly payments
Simple example: $10,000 personal loan at 12% APR for 36 months (3 years):
- Monthly rate = 12% ÷ 12 = 1% = 0.01
- Monthly payment = $10,000 × [0.01 × (1.01)^36] ÷ [(1.01)^36 − 1] = $332
- Total paid = $332 × 36 = $11,952
- Total interest = $11,952 − $10,000 = $1,952
The free loan calculator handles this math automatically. Enter $10,000, 12%, 36 months and you get $332/month instantly, along with the full amortization schedule.
| Loan Amount | Interest Rate | Term | Monthly Payment | Total Interest |
|---|---|---|---|---|
| $5,000 | 10% | 24 months | $230 | $524 |
| $10,000 | 12% | 36 months | $332 | $1,952 |
| $15,000 | 14% | 48 months | $409 | $4,648 |
| $20,000 | 18% | 60 months | $508 | $10,480 |
| $25,000 | 10% | 60 months | $531 | $6,861 |
How Interest Rate Affects Your Monthly Payment and Total Cost
Interest rate has a bigger impact on total cost than most borrowers realize. On a $20,000 personal loan over 5 years:
| APR | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|
| 7% (excellent credit) | $396 | $3,761 | $23,761 |
| 12% | $445 | $6,693 | $26,693 |
| 18% | $508 | $10,480 | $30,480 |
| 24% | $575 | $14,516 | $34,516 |
| 36% (bad credit) | $727 | $23,618 | $43,618 |
The difference between 7% and 36% APR on the same $20,000 loan: $331 more per month and $19,857 more in total interest. Credit score is the primary driver of the interest rate you qualify for — improving your credit before applying for a personal loan can save thousands.
Personal loan interest rates as of 2026: excellent credit (750+ FICO) qualifies for 6-10% APR at most major lenders. Good credit (700-749) typically qualifies for 10-15%. Fair credit (650-699) often gets 15-22%. Poor credit (below 650) typically sees 22-36%.

Personal loans typically range from 12 to 84 months. Here is how term length affects payments for a $15,000 loan at 12% APR:
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 24 months | $705 | $1,924 |
| 36 months | $498 | $2,940 |
| 48 months | $395 | $3,967 |
| 60 months | $333 | $5,005 |
| 72 months | $292 | $6,067 |
| 84 months | $263 | $7,148 |
Longer terms: lower monthly payment, much higher total interest. Shorter terms: higher monthly payment, much lower total interest. The optimal term depends on your cash flow situation. If you can afford the $705/month payment, the 24-month loan saves you $5,224 in interest compared to the 84-month loan. If cash flow is tight, the 60-month payment may be more manageable even though it costs more overall.
Use the free loan calculator to compare different term lengths for your specific loan amount and rate. The calculator shows you total interest for each scenario, making the cost comparison immediate.
Personal Loan Interest Rates by Credit Score (2026)
Personal loan rates vary by lender and credit profile. Here are approximate ranges from major lenders as of early 2026:
| Credit Score Range | Credit Category | Typical APR Range | Best APR Available |
|---|---|---|---|
| 800+ | Exceptional | 5.99% - 9.99% | 5.49% (credit unions) |
| 750-799 | Very Good | 8.99% - 14.99% | 7.99% |
| 700-749 | Good | 12.99% - 19.99% | 11.99% |
| 650-699 | Fair | 16.99% - 24.99% | 15.99% |
| 600-649 | Poor | 22.99% - 35.99% | 21.99% |
| Below 600 | Very Poor | 28.99% - 36%+ | Limited options |
Credit unions typically offer lower rates than banks and online lenders for qualified members. If you belong to a credit union, check their personal loan rates first. Online lenders (LightStream, SoFi, Marcus, Discover) are competitive for borrowers with good-to-excellent credit and often provide next-day funding.
Before applying: get pre-qualified at multiple lenders (soft credit pull, does not affect your score) to compare rates. Enter each rate into the free loan calculator to calculate the exact monthly payment and total interest difference between offers.
When a Personal Loan Makes Financial Sense — and When It Does Not
Good uses for personal loans:
- Debt consolidation: Combining multiple high-rate credit cards (18-29% APR) into a single personal loan at a lower rate (10-15% APR) can save significant interest. Use the calculator to compare what you currently pay in total interest vs what you would pay with a consolidation loan.
- Home improvement without home equity: If you need to make repairs quickly and lack home equity to tap, a personal loan is often more affordable than credit cards.
- Large planned expenses: Medical bills, wedding costs, or moving expenses where you know the total upfront and can budget a fixed monthly payment.
- Building credit: A personal loan adds installment credit to your credit profile, which helps diversify your credit mix and can improve your credit score over time with on-time payments.
Poor uses for personal loans:
- Discretionary spending you cannot afford (financing a vacation or luxury items)
- When you have high-cost debt that will continue to accrue (paying minimum on credit cards while adding a loan does not help)
- Business investments with uncertain returns — if the investment fails, you still owe the fixed loan payments
If you are paying off existing debt, also see the debt payoff calculator to compare the snowball vs avalanche payoff methods — sometimes a personal loan for consolidation is faster than even the avalanche method on multiple debts.

Is a 3-year or 5-year personal loan better?
A 3-year loan has higher monthly payments but significantly lower total interest. A 5-year loan has lower payments but you pay considerably more interest over the full term. Choose the shortest term you can comfortably afford each month.
