Free Personal Loan Calculator - Calculate Loan Payments & Interest Costs
Loan payments are calculated using the loan amount, interest rate, and term length. For a $25,000 loan at 6.5% over 5 years, monthly payments would be approximately $490, with total interest of $4,380. The payment formula accounts for principal repayment and interest charges over the full amortization period.
This calculator uses the standard amortization formula PMT = P[r(1+r)^n]/[(1+r)^n - 1] and supports multiple payment frequencies to show the true cost of borrowing.
This Loan Calculator calculates payments for personal loans, car loans, and lines of credit using standard Canadian banking formulas. It provides detailed amortization schedules showing exactly how each payment is split between principal and interest over the life of the loan.

Periodic payments are calculated using the standard amortization formula, which spreads principal and interest evenly across the full term.
Actual lender schedules may differ slightly due to rounding conventions and compounding frequency.
Standard Amortization Formula
PMT = P[r(1+r)^n] / [(1+r)^n - 1]
Input the total amount you plan to borrow. This is the principal amount before any interest charges. For car loans, this is typically the vehicle price minus your down payment.
Enter the annual interest rate offered by your lender and the loan term in years. Compare different rates and terms to see how they affect your monthly payment and total interest cost.
Select monthly, biweekly, or weekly payments. Accelerated biweekly payments (paying half the monthly amount every two weeks) result in one extra monthly payment per year, saving interest.

Interest rates vary dramatically between lenders. On a $25,000 5-year loan, 5.99% vs 8.99% means $1,900 more in interest. Check banks, credit unions, and online lenders. Even 0.5% difference saves hundreds. Pre-qualification doesn't hurt credit score.
Shorter terms have lower interest rates and save thousands in total interest. A $20,000 loan at 6%: 3 years costs $1,867 interest vs 5 years at $3,199 interest. If budget allows, choose shorter terms even if payments are $100-150 higher monthly.
Pay half your monthly payment every two weeks instead of full payment monthly. This equals 13 monthly payments yearly instead of 12. Extra payment goes to principal, reducing interest and term. On a $20,000 5-year loan, saves $300+ in interest.
If your payment is $387, pay $400. Small extra amounts compound significantly. On a $20,000 loan at 6.5% for 5 years, rounding $393 to $425 ($32 extra) saves $375 interest and pays off 8 months early. Barely noticeable monthly, huge impact overall.
Skipping payments extends your loan and adds interest charges. One skipped $400 payment on a $20,000 loan at 6.5% costs an extra $260 in interest over the loan's life. Only skip if absolutely necessary. Never skip just for convenience.
If interest rates drop 1%+ or your credit improves significantly, refinance. On a $25,000 loan with 3 years remaining, refinancing from 8% to 6% saves $750+ in interest. Watch for prepayment penalties on your current loan before refinancing.
Low monthly payments seem attractive but often mean longer terms and much higher total interest. A $20,000 loan with $200/month payment might cost $8,000+ in interest over 10 years. Always calculate total cost, not just monthly payment. Lower payment isn't always better.
Some loans charge fees for early payoff (3-6 months interest). A $25,000 loan with 3-month penalty costs $500-800 if paid early. Always ask about prepayment penalties before signing. Avoid loans with these penalties if you plan to pay extra or refinance.
Don't risk your car or home for a vacation or wedding. Secured loans (car loans, home equity loans) have lower rates but you lose the asset if you default. Use secured loans only for necessity purchases or investments that justify the risk.
Lenders approve more than you should borrow. Approved for $30,000 doesn't mean you need it. Borrow minimum necessary. Every extra $5,000 at 7% over 5 years costs $950 in interest. Less debt means more financial flexibility and security.
The original amount borrowed, not including interest. On a $20,000 loan, $20,000 is principal. Each payment reduces principal and pays interest. Early payments are mostly interest, later payments are mostly principal due to amortization.
Annual percentage charged to borrow money. A 6% rate on $20,000 costs $1,200 first year (decreases as principal reduces). Your rate depends on credit score, income, loan type, and lender. Lower rates save thousands over loan life.
Length of time to repay the loan, typically 1-7 years for personal loans, 3-7 years for car loans. Longer terms mean lower monthly payments but much more total interest. Shorter terms save money but require higher monthly payments.
Fixed amount paid each month including both principal and interest. Payment stays same throughout loan (in most cases) but the split between principal and interest changes. Early payments are mostly interest, later payments are mostly principal.
True cost of borrowing including interest rate plus fees, expressed as yearly rate. Always higher than stated interest rate when fees exist. Use APR to compare loans accurately. A 5.99% rate with $500 fees might be 7% APR.
Process of paying off loan with regular payments over time. Amortization schedule shows how each payment splits between principal and interest. Early payments pay mostly interest, later payments pay mostly principal. This is why extra payments early save most interest.
Loan backed by collateral (car, home, savings). Lower rates because lender can seize asset if you default. Car loans and mortgages are secured. Missing payments means losing your asset. Lower risk for lender = lower rate for you.
Loan not backed by collateral. Personal loans and credit cards are unsecured. Higher rates (7-15%+) because lender has higher risk. Approval based entirely on creditworthiness. Default hurts credit but lender can't seize assets directly.
