How is my personal loan monthly payment calculated?

Your monthly payment is calculated using the standard amortization formula M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of payments (years × 12). The origination fee is deducted from the loan proceeds upfront, so you receive less than the loan amount but repay the full amount.

What is the difference between interest rate and APR?

The interest rate is the cost of borrowing the principal, expressed as a percentage. The APR (Annual Percentage Rate) includes the interest rate plus fees like origination fees, giving you the true annual cost of the loan. For personal loans with origination fees, the APR is always higher than the stated rate. Always compare loans by APR, not just rate.

What is an origination fee?

An origination fee is a one-time charge deducted from your loan proceeds before the funds are disbursed. Typical fees range from 1% to 6% of the loan amount. For example, a $15,000 loan with a 3% origination fee means you receive $14,550 but repay $15,000 plus interest. The fee compensates the lender for processing and underwriting the loan.

What is a good interest rate for a personal loan?

As of 2026, personal loan rates for borrowers with excellent credit (740+) start around 6%–8%. Rates for good credit (670–739) range from 9%–15%. Rates for fair credit (580–669) range from 15%–20%, and rates for poor credit (below 580) can exceed 25%. Always compare offers from multiple lenders to find the best rate.

How long should my personal loan term be?

Personal loan terms typically range from 1 to 7 years. Shorter terms (1–3 years) have higher monthly payments but lower total interest. Longer terms (4–7 years) have lower monthly payments but higher total interest. The sweet spot for most borrowers is 2–4 years, balancing affordability with reasonable total cost. Avoid terms longer than 5 years unless necessary.

Can I pay off my personal loan early?

Most personal loans allow early payoff, but some lenders charge prepayment penalties (typically 1%–5% of the remaining balance). Check your loan agreement for prepayment clauses. Even with a small penalty, paying off early can save more in interest than the penalty costs. Making extra payments or rounding up your monthly payment can also reduce the term and total interest.

Is a personal loan better than a credit card?

Personal loans typically have lower rates (6%–25%) than credit cards (15%–30%) and offer fixed terms, making them better for large one-time expenses or consolidating credit card debt. However, credit cards offer flexibility (revolving balance, minimum payments) and rewards. For amounts under $10,000 that you can repay within 12–18 months, a 0% intro APR credit card may be cheaper.

How does my credit score affect my personal loan rate?

Your credit score is the primary factor lenders use to set your rate. Improving your score by 30+ points can unlock rates 2%–5% lower. Before applying, check your credit report for errors, pay down existing debt to lower your utilization ratio, and avoid applying for new credit in the 6 months before a personal loan application.

Formula

How It's Calculated

The monthly payment for a personal loan uses the standard amortization formula:

M = P × [r(1+r)^n] / [(1+r)^n − 1]

Where:
- M = monthly payment (principal + interest)
- P = loan amount
- r = monthly interest rate (annual rate ÷ 12)
- n = total number of payments (years × 12)

Origination fee is deducted upfront:
  fee = loanAmount × originationFeeRate
  netProceeds = loanAmount − fee

APR approximates the fee's effect on borrowing cost:
  APR ≈ rate + (fee ÷ months × 12) ÷ netProceeds

For example, a $15,000 loan at 9.5% APR over 3 years with 3% origination fee:
- Fee = $450 (deducted from proceeds)
- Net proceeds = $14,550
- r = 0.095 / 12 = 0.0079167
- n = 36
- M = $480.21/mo
- Total paid = $17,287.56
- Total interest = $2,287.56
- APR ≈ 11.5% (higher than the 9.5% stated rate due to the fee)
