Car loan vs personal loan
A car loan is usually secured by the vehicle. Rates tend to be lower than unsecured personal loans because the lender can repossess the car if you default. Use the car loan calculator when you're buying or refinancing a vehicle. Try our car loan with trade-in or affordability calculator for more specific scenarios.
A personal loan is typically unsecured. You can use it for almost anything—debt consolidation, home improvements, medical bills, or even a car if you prefer not to use dealer financing. Rates are often higher than secured auto loans but may beat credit card APRs. Use our debt consolidation or bad credit calculators for specialized cases.
Mortgage vs other loans
Mortgage calculators handle long terms (10, 15, 20, or 30 years) and large amounts. The math is the same amortization formula, but mortgages involve property taxes, insurance, and often PMI—our tool shows principal and interest only. Compare 15-year vs 30-year to see payment and interest trade-offs.
When to use the general loan calculator
Our main loan calculator works for any amount and term. Use it when you want flexibility across currencies and scenarios, or when your loan doesn't fit neatly into car, personal, or mortgage buckets. It also supports down payments, extra payments, and interest breakdown.
Country-specific calculators
We offer localized guidance for USA, UK, Canada, Australia, UAE, and more. These use the same payment math but include regional context on rates and terms.
