FHA vs Conventional Mortgage
When a buyer does not have a large down payment, the choice often narrows to an FHA-insured loan or a conventional mortgage. Both can get you into a home with less than 20 percent down, but they are structured differently. An FHA loan is insured by the Federal Housing Administration and carries its own mortgage insurance: an upfront premium and an annual premium paid monthly. A conventional loan is not government-insured, but most lenders require private mortgage insurance (PMI) when the down payment is below 20 percent. The cheapest monthly payment is not always the lowest long-term borrowing cost, so the comparison has to look at the whole payment structure.
This page compares the two calculators. It is informational, not a loan offer, approval, or underwriting decision.
What each calculator does
The FHA loan calculator estimates the payment pieces that make an FHA-insured mortgage different: down payment, base loan amount, principal and interest, upfront mortgage insurance premium, annual mortgage insurance premium paid monthly, and total scheduled payments. It deliberately excludes property taxes, homeowners insurance, HOA dues, and repairs so the program-specific costs are easy to see.
The home mortgage calculator is the conventional-style buyer’s estimate. It starts from the purchase price and down payment percentage, computes the fixed-rate principal-and-interest payment, then layers on property tax estimated from a rate, monthly homeowners insurance, monthly HOA dues, and PMI — which is included only when the down payment is under 20 percent.
Side-by-side comparison
| Feature | FHA loan calculator | Home mortgage (conventional-style) calculator |
|---|---|---|
| Typical down payment | 3.5% common default assumption | Percentage you enter; PMI triggers below 20% |
| Mortgage insurance | Upfront MIP plus annual MIP paid monthly | PMI only when down payment is under 20% |
| Upfront insurance charge | Modeled separately | Not modeled |
| Property tax | Not included | Estimated from an annual tax rate |
| Insurance and HOA | Not included | Monthly amounts entered by the user |
| Total scheduled payments | Shown | Monthly all-in estimate shown |
| Input style | MIP rates entered from quotes | PMI rate entered from quote, tax as a rate |
When to use which
Start with whichever financing path you are actually pursuing. If you are shopping FHA, use the FHA calculator to see how the upfront and annual mortgage insurance change the total scheduled payments — those program-specific costs are the reason an FHA payment estimate differs from a plain conventional one. If you are comparing a conventional purchase, use the home mortgage calculator to see how taxes, insurance, HOA dues, and PMI turn a listing price into a monthly ownership estimate.
To compare the two paths fairly, keep the assumptions aligned: same home price, rate, and term, and remember that the FHA page excludes taxes and insurance while the conventional-style page includes them, so the raw numbers are not directly comparable until you add the missing pieces. Also compare total scheduled payments and cash due, not just the monthly payment — a lower monthly number can come with higher total cost. FHA eligibility can depend on credit, debt-to-income ratio, occupancy, appraisal, loan limits, and lender overlays, so confirm program details with current HUD and lender guidance.
