Enter your loan amount, annual interest rate, and term. The calculator shows your monthly payment, total interest, and true APR (which includes any origination fees). Add an extra monthly payment to see how much you can save.
The interest rate is the base cost of borrowing. APR (Annual Percentage Rate) includes the interest rate plus fees and other costs, expressed as a yearly rate. APR is the best number to compare across different loan offers.
Three main strategies: (1) Make extra principal payments — even $50/month saves significant interest over time. (2) Choose a shorter loan term — higher payments but far less total interest. (3) Refinance at a lower rate if your credit improves. The calculator shows the impact of extra payments clearly.
Most lenders offer their best rates (below 12%) to borrowers with credit scores above 720. Scores 680–719 typically qualify for mid-range rates. Below 680, rates rise significantly, and below 580, options become limited to secured loans or specialist lenders.
