How to Use Our FHA vs. Conventional Calculator
Use the calculator above to compare FHA and conventional mortgage payments using the same basic home and loan assumptions.
Keep in mind that FHA and conventional mortgage rates can vary based on your unique financial situation.
| Input |
What It Means |
Why It Matters |
| Home price and down payment |
The shared purchase assumptions |
These determine the base loan amount for both options. |
| FHA and conventional rates |
The interest rates entered for each loan type |
These affect the principal-and-interest payment. |
| Taxes and insurance estimate |
1.6% of home price annually, split monthly |
These costs are held constant in both scenarios. |
| Mortgage insurance |
FHA MIP or conventional PMI |
This is often where the comparison changes direction. Keep in mind that both are estimates, and your actual MIP or PMI will depend on your unique financial situation. |
How The FHA Vs. Conventional Calculator Works
This calculator compares two financing paths using the same home price, down payment, loan term, and shared estimate for property taxes and insurance.
That keeps the comparison focused on the financing structure rather than changing multiple assumptions at once.
FHA and conventional loans both have mortgage insurance requirements that are factored into our calculator.
On the FHA side, the model starts with the base loan amount and adds a 1.75 percent upfront mortgage insurance premium if you choose to finance it. Monthly principal and interest are then calculated at the FHA rate, and the model adds annual MIP of 0.55 percent divided by 12.
On the conventional side, monthly principal and interest are calculated at the conventional rate on the base loan amount. If the down payment is below 20 percent, the model also adds PMI at 0.5 percent per year divided by 12.
What The Comparison Is Really Showing
The main result is the estimated monthly cost difference under the assumptions built into the tool. It can highlight how upfront FHA mortgage insurance and monthly MIP compare with conventional PMI and the conventional interest rate you entered.
This is useful because the better option is not always the one with the lower nominal rate. Mortgage insurance, financed upfront charges, and down payment size can all shift the comparison.
The calculator is not making an approval decision. It is showing how the estimated monthly payment components line up when the loan structures are held side by side.
When FHA May Look Stronger
FHA can look more favorable when the FHA rate is materially lower, when the borrower has a smaller down payment, or when conventional pricing is less competitive for the scenario being tested.
Because FHA allows the upfront mortgage insurance premium to be financed, the out-of-pocket cash picture may also look different from conventional, even if the total financed balance is higher.
When Conventional May Look Stronger
Conventional can look stronger when the borrower has a larger down payment, when the conventional rate is close to the FHA rate, or when the PMI burden is lighter than FHA’s mortgage insurance structure.
Borrowers also often look at the long-term exit path. Depending on the loan and equity position, conventional mortgage insurance may drop off sooner than FHA mortgage insurance, which can change the longer-term cost picture.
What The Calculator Can And Cannot Tell You
This tool is good for side-by-side payment estimates. It is not a full underwriting model and it does not capture every real-world variable, such as credit-score-based pricing, county loan limits, financed closing costs, or changing insurance premiums.
It also does not tell you which loan you qualify for. It simply gives you a cleaner framework for comparing estimated monthly cost under consistent assumptions.
The Bottom Line
Our FHA-vs.-conventional calculator gives you a clean way to compare two common loan structures without changing the house, down payment, or term. Use it to understand the payment tradeoffs, then confirm the real numbers against actual quotes and disclosures.
Frequently Asked Questions
Is FHA Or Conventional Cheaper?
It depends on the rate, down payment, and mortgage insurance assumptions. This calculator is designed to show which option looks lower-cost on a monthly basis under the numbers you enter.
What Is Included In The FHA Calculation?
The model includes principal and interest at the FHA rate, annual MIP divided monthly, and the option to finance the 1.75 percent upfront MIP into the loan amount.
What Is Included In The Conventional Calculation?
The model includes principal and interest at the conventional rate and adds PMI of 0.5 percent per year divided monthly when the down payment is below 20 percent.
Why Are Taxes And Insurance Kept The Same?
Keeping taxes and insurance constant makes it easier to isolate the financing differences between FHA and conventional.
