US Loan Calculators 2026

Whether you're buying a home, financing a car or paying down credit card debt, understanding the true cost of borrowing is essential. US interest rates are influenced by Federal Reserve monetary policy, the prime rate, your credit score and the type of loan.

Mortgage loans typically range from 15 to 30 years. The 30-year fixed mortgage offers the lowest monthly payment but costs significantly more in total interest. A 15-year mortgage costs more per month but builds equity faster and has a lower rate.

Auto loans in 2026 average 5–9% APR for new vehicles and 7–14% for used vehicles, depending on credit score. Most auto loans run 48–72 months. A longer term reduces monthly payments but increases total interest and raises the risk of being underwater on the vehicle.

Credit card debt carries the highest rates of any common consumer debt, averaging 20–28% APR in 2026. Prioritising credit card payoff — especially with the avalanche method — has the highest guaranteed return of any financial move available to most Americans.
