Understanding FHA Loans and This Calculator
An FHA loan is a mortgage insured by the Federal Housing Administration. These loans are popular among first-time homebuyers because they require lower minimum credit scores and down payments than many conventional loans. This calculator helps you determine the full cost of homeownership under FHA guidelines.
Key FHA Mortgage Components
- Down Payment: The minimum down payment for an FHA loan is currently 3.5% for borrowers with a credit score of 580 or higher.
- Upfront Mortgage Insurance Premium (UFMIP): FHA requires a one-time upfront premium, usually 1.75% of the loan amount. This calculator automatically adds this to your base loan amount, as most borrowers finance this fee.
- Monthly Mortgage Insurance Premium (MIP): Unlike conventional private mortgage insurance (PMI), FHA MIP is required for the life of the loan if you put down less than 10%. This calculator uses the standard 0.55% annual rate for 30-year loans.
- PITI: This stands for Principal, Interest, Taxes, and Insurance—the four main components of a monthly mortgage payment.
FHA Loan Example Calculation
Suppose you purchase a home for $300,000 with a 3.5% down payment ($10,500):
- Base Loan Amount: $289,500
- Upfront MIP (1.75%): $5,066.25
- Total Loan Balance: $294,566.25
- Monthly Principal & Interest (at 6.5%): Approximately $1,861.85
- Monthly MIP (0.55% annual): Approximately $132.69
- Total: Adding taxes and insurance, your total monthly commitment would be roughly $2,394.54.
FHA Loan Requirements 2024
To qualify for an FHA loan, you typically need a debt-to-income (DTI) ratio below 43%, though some lenders allow higher with compensating factors. The property must also serve as your primary residence and meet specific safety and habitability standards during an FHA appraisal.
