FHA vs Conventional Loan Calculator

The FHA vs conventional loan calculator builds a complete cost model for each loan type, accounting for the different down payment requirements, mortgage insurance structures, and interest rates to show you which option is more affordable over time. For the conventional loan scenario, the calculator uses your chosen down payment percentage and conventional interest rate. If the down payment is below 20 percent, it adds private mortgage insurance at a rate based on your credit score and loan-to-value ratio. Conventional PMI can be removed once you reach 20 percent equity, so the calculator factors in the date when PMI drops off and adjusts the total cost accordingly. For the FHA loan scenario, the calculation is different because FHA mortgage insurance has two components. First, there is an upfront mortgage insurance premium of 1.75 percent of the loan amount, which is typically financed into the loan. Second, there is an annual mortgage insurance premium that ranges from 0.45 to 1.05 percent depending on the loan amount, term, and loan-to-value ratio. For most borrowers putting less than 10 percent down, FHA mortgage insurance lasts for the life of the loan and cannot be canceled without refinancing. The calculator computes the monthly payment for each loan type including principal, interest, and the applicable mortgage insurance. It then calculates the total cost over a specified period, typically 5, 10, or 30 years, so you can see which loan is cheaper depending on how long you plan to keep it. FHA loans often have lower interest rates and more lenient credit requirements, but the permanent mortgage insurance can make them more expensive over the long run. Conventional loans may have higher rates for borrowers with lower credit scores, but the ability to remove PMI at 20 percent equity can result in lower total costs for buyers who plan to stay in the home.
