What is FHA Loan Calculator?
An FHA loan calculator models financing backed by the Federal Housing Administration (HUD). FHA loans require an Upfront Mortgage Insurance Premium (UFMIP, typically 1.75% financed into the loan) and an Annual Mortgage Insurance Premium (MIP, typically 0.55% for 30-year loans).
How to Use This Calculator
- Enter home purchase price.
- Choose down payment (minimum 3.5% with 580+ FICO score).
- Input interest rate.
- The calculator auto-finances 1.75% upfront MIP and adds monthly MIP to debt service.

Step-by-Step Worked Example
Scenario: $300,000 home with 3.5% down ($10,500) at 6.25% interest for 30 years.
- Base Loan = $300,000 - $10,500 = $289,500.
- Upfront MIP (1.75%) = $289,500 * 0.0175 = $5,066.25.
- Total Financed = $289,500 + $5,066.25 = $294,566.25.
- Monthly P&I on $294,566.25 at 6.25% = $1,813.56.
- Annual MIP (0.55%) = ($294,566.25 * 0.0055) / 12 = $135.01/month.
- Estimated Taxes & Insurance = $366.23/month.
- Total Monthly Outlay = $2,314.80.
Result: Total monthly payment is $2,314.80 including P&I and FHA MIP.
Frequently Asked Questions
Does FHA mortgage insurance ever go away?
For loans initiated with less than 10% down payment, FHA MIP remains for the entire life of the loan. The only way to remove it is to refinance into a conventional loan once you have 20% equity.
What credit score is needed for 3.5% down on an FHA loan?
HUD guidelines require a minimum FICO credit score of 580 for 3.5% down. Borrowers with scores between 500 and 579 are eligible with a 10% down payment.
