Personal Loan Calculator
Last Updated:
Calculate your exact monthly payment, total interest, and total cost for any personal loan.
Monthly Payment
$0.00
📐 Formula
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n − 1] where P = principal, r = monthly rate, n = months
How to Use the Personal Loan Calculator
Enter the loan amount
Input the amount you need to borrow. Note that origination fees (1–8%) may be deducted from disbursement — you may need to borrow slightly more to receive the exact amount needed.
Set the interest rate
Enter your loan's APR — the legally required all-in rate including fees. Always compare APRs across lenders, not base rates, which can obscure fee structures.
Choose the term
Personal loans typically range 12–84 months. Compare total interest paid across terms, not just monthly payment — the total cost difference is significant.
Evaluate the purpose test
Would this loan's purpose generate value (debt consolidation savings, unavoidable expense) that justifies the total interest cost? If not, review alternatives.
When a Personal Loan Makes Financial Sense
Personal loans are most valuable in three scenarios. First, debt consolidation: replacing multiple 20–24% APR credit cards with a single 10–15% personal loan reduces total interest and simplifies repayment. On $15,000 of credit card debt, this rate difference can save $1,500–$2,500 in annual interest charges. Second, large necessary expenses: medical bills, emergency home repairs, or other unavoidable costs where savings do not yet cover the amount. Third, building credit: a small instalment loan repaid on time builds payment history and credit mix — both positive credit score factors.
Origination Fees: The Hidden Cost
A $10,000 loan with a 5% origination fee nets you $9,500 while requiring repayment of the full $10,000 plus interest — the effective rate is higher than the stated APR suggests. The APR calculation is legally required to include fees, so always compare APRs across lenders rather than base interest rates. Online lenders (SoFi, LightStream, Marcus) consistently offer lower APRs and fees than traditional banks for creditworthy borrowers. Getting pre-qualified with 3–4 lenders via a soft credit check (which does not affect your score) takes 15 minutes and can save hundreds of dollars in interest.
