FHA Loan Calculator

The FHA loan calculator estimates the payment pieces that make an FHA-insured mortgage different from a plain conventional loan estimate. It separates principal and interest from mortgage insurance, shows the upfront mortgage insurance premium, and displays the total FHA loan amount for context. That makes it especially useful for borrowers comparing a low down payment with the cost of mortgage insurance. For a conventional-style estimate, use the mortgage calculator. For a veteran or service-member scenario, compare the VA loan calculator. For income fit, use the debt-to-income calculator.

How the calculator works

Enter the home price, down payment percentage, interest rate, loan term, annual MIP rate, and upfront MIP rate. The calculator converts the down payment percentage into dollars, subtracts it from the home price to find the base loan amount, and amortizes that base loan amount over the term. It then calculates upfront MIP as a percentage of the base loan amount and monthly MIP as the annual MIP rate divided into 12 monthly pieces.

The calculator displays total FHA loan amount as base loan amount plus upfront MIP, but the principal-and-interest payment is calculated on the base loan amount. Many real FHA loans finance upfront MIP into the mortgage, so a lender’s final principal-and-interest payment can be higher than this model if the financed upfront MIP is included in the amortized balance. The worked example below uses the same base-loan assumption shown in the result labels.

Formula

Down payment:

$\text{down payment} = \text{home price} \times \text{down payment percent}$

Base loan amount:

$\text{base loan amount} = \text{home price} - \text{down payment}$

Principal and interest:

$\text{principal and interest} = \frac{\text{base loan amount} \times \text{monthly rate}}{1 - (1 + \text{monthly rate})^{-\text{number of payments}}}$

Upfront mortgage insurance premium:

$\text{upfront MIP} = \text{base loan amount} \times \text{upfront MIP rate}$

Monthly mortgage insurance premium:

$\text{monthly MIP} = \frac{\text{base loan amount} \times \text{annual MIP rate}}{\text{12}}$

Estimated monthly payment with MIP:

$\text{monthly payment with MIP} = \text{principal and interest} + \text{monthly MIP}$

Worked example matching the default inputs

The default scenario uses a $350,000 home price, 3.5% down payment, 6.5% interest rate, 30-year term, 0.55% annual MIP, and 1.75% upfront MIP. The down payment is:

$\text{down payment} = \text{350,000 dollars} \times \text{3.5\%} = \text{12,250 dollars}$

The base loan amount is $337,750. Amortizing $337,750 at 6.5% for 360 payments gives principal and interest of $2,134.81 per month. Upfront MIP is:

$\text{upfront MIP} = \text{337,750 dollars} \times \text{1.75\%} = \text{5,910.63 dollars}$

The total FHA loan amount displayed by the calculator is $343,660.63. Monthly MIP is:

$\text{monthly MIP} = \frac{\text{337,750 dollars} \times \text{0.55\%}}{\text{12}} = \text{154.80 dollars}$

The primary result is therefore $2,289.61 per month, which equals $2,134.81 of principal and interest plus $154.80 of monthly MIP. The number of payments is 360, and total scheduled payments in the calculator are $824,260.26.

Eligibility, MIP, and costs

FHA loans are insured by the Federal Housing Administration and are often used by borrowers who want a low down payment or more flexible credit standards than some conventional programs. HUD and FHA rules still matter. A borrower may need to meet credit, income, occupancy, property-condition, appraisal, and loan-limit requirements, and lenders may add overlays. The calculator does not check any of those requirements.

Mortgage insurance is the main cost distinction on this page. FHA’s annual MIP rate and duration can depend on loan term, loan amount, and loan-to-value. The default rates are editable assumptions, not a guarantee. Ask the lender for the current MIP schedule and compare the result with official disclosures. If a conventional loan with private mortgage insurance is available, compare the total monthly payment and how long insurance may last. If military service makes VA eligibility possible, the VA loan calculator can show the funding-fee structure that replaces monthly mortgage insurance in many VA scenarios.

Tips before choosing FHA

• Add taxes, homeowners insurance, HOA dues, repairs, and utilities outside this calculator before deciding affordability.
• Test a larger down payment if it reduces MIP costs or improves approval odds.
• Check FHA loan limits for the county and property type.
• Keep cash reserves; low down payment does not remove moving, repair, and maintenance costs.
• Compare APR and total payment, not only the advertised interest rate.

Also ask the lender to show the same purchase price under more than one loan program. FHA can be the practical path for a borrower with limited cash, but a slightly higher down payment, a different property price, or improved credit may change the comparison. A clean side-by-side quote helps separate the benefit of getting approved from the long-term cost of insurance.

Informational note

This calculator is educational and reflects the form’s current compute method. It is not an FHA approval, lender quote, appraisal review, or official MIP schedule. Use HUD resources, lender disclosures, and qualified professional guidance for program rules and final payment obligations.
