Why It Matters
The Real Cost of a Personal Loan
The APR you see advertised is not what you actually pay — it's the annual cost of borrowing expressed as a percentage. What matters is the total dollar amount leaving your pocket. A $10,000 loan at 15% APR for 5 years costs $4,274 in total interest. At 10% APR for 3 years, the same loan costs $1,616 in total interest — less than half, paid off in 60% of the time. The calculator above makes this concrete with your exact numbers.

Smart Strategies
How to Borrow Less Expensively
📊
Improve Your Credit Score First
Moving from 650 to 720 can cut your APR by 4–8 percentage points. On a $15,000 loan, that's $2,000–$4,000 in interest savings over 5 years.
🔍
Compare At Least 3–5 Lenders
APRs on the same loan profile can vary by 5–10% between lenders. Pre-qualification uses a soft inquiry that won't hurt your credit score.
⏱️
Choose the Shortest Term You Can Afford
A shorter term means higher monthly payments but dramatically less total interest. Use the comparison table above to see the difference in dollars.
🏦
Watch Out for Origination Fees
A 5% origination fee on a $10,000 loan means you only receive $9,500 but owe $10,000. Factor this into your comparison — sometimes a higher APR with no fee is cheaper.
Common Questions
Personal Loan FAQ
How is my personal loan monthly payment calculated? ▾
Personal loan payments use the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is the loan principal, r is the monthly interest rate (APR ÷ 12), and n is the number of monthly payments. Each payment covers that month's interest first, with the remainder reducing your principal balance.
What is a good APR for a personal loan in 2026? ▾
The average personal loan APR in 2026 is around 12–14% for borrowers with good credit (700+). Borrowers with excellent credit (750+) can often qualify for rates below 10%. Rates above 20–25% are typical for borrowers with poor credit. The best strategy is to improve your credit score and compare offers from multiple lenders before accepting anything.
What is the difference between APR and interest rate? ▾
The interest rate is the base cost of borrowing. APR includes the interest rate plus any fees (like origination fees), expressed as a yearly rate. For personal loans, APR is the more accurate measure of true borrowing cost. A lender advertising a 9% interest rate with a 5% origination fee can have an effective APR of 12% or more — always compare APRs, not just rates.
Is it better to choose a shorter or longer loan term? ▾
Shorter terms mean higher monthly payments but far less total interest. For a $15,000 loan at 12% APR, a 3-year term costs about $2,980 in interest. The same loan over 5 years costs $5,020 — nearly $2,000 more. If your budget can handle the higher monthly payment, the shorter term is almost always the better financial decision. Use the comparison table above to see your specific numbers.
Can I pay off a personal loan early? ▾
Most personal loans allow early payoff, but some lenders charge a prepayment penalty — typically 1–5% of the remaining balance. Always check your loan agreement. If there's no prepayment penalty, paying extra each month reduces your total interest cost significantly since personal loans are front-loaded with interest.
What credit score do I need to get a personal loan? ▾
Most mainstream lenders require a minimum score of 580–640. A score below 670 typically results in rates of 18–30%+ APR. Scores above 720 qualify for the most competitive rates. Some lenders specialize in bad-credit loans but APRs can approach the 36% legal maximum. If your score is below 670, it's often worth spending 6–12 months improving it before borrowing.

How Personal Loan Interest Works
Personal loans are fully amortizing, which means every payment covers both interest and principal, and the loan balance reaches exactly zero on the final payment. Unlike a credit card — where interest compounds on a revolving balance — a personal loan has a fixed payment schedule from day one. The downside is that interest is front-loaded: in the early months, the majority of each payment goes toward interest rather than reducing your balance. This is why paying extra early in the loan saves more than paying extra later.
APR vs. Interest Rate: Why the Difference Matters
The stated interest rate tells you the cost of borrowing before fees. APR incorporates the interest rate and fees into a single annualized number, making it a better apples-to-apples comparison between lenders. A lender offering a 9.5% rate with a 4% origination fee can be more expensive in practice than a lender offering 11% with no origination fee — particularly on shorter loan terms. The calculator above includes an origination fee field specifically for this reason. Always compare the total dollar cost, not just the APR percentage.
When a Personal Loan Makes Financial Sense
Personal loans make sense when the APR is significantly lower than the rate you'd otherwise pay — most commonly for credit card debt consolidation. If you're carrying $15,000 across credit cards at an average of 22% APR, refinancing into a personal loan at 12% APR for 3 years saves roughly $3,500 in interest. Personal loans also make sense for one-time large expenses (medical bills, home repairs, moving costs) where a fixed payoff timeline is preferable to open-ended revolving debt. They don't make sense for ongoing expenses — that's a budgeting problem, not a borrowing problem.
Origination Fees: The Hidden Cost Most People Ignore
An origination fee is a one-time charge deducted from the loan proceeds before you receive the money. A 5% fee on a $10,000 loan means you receive $9,500 but owe and must repay $10,000 plus interest. This effectively increases your APR. On a 2-year loan, a 5% origination fee adds roughly 2.5 percentage points to your effective APR. On a 5-year loan, it adds about 1 percentage point. The fee has more impact on shorter-term loans — another reason to compare total dollar cost rather than just the advertised APR.
