What the FHA Loan Calculator does
An FHA loan is a mortgage insured by the Federal Housing Administration, part of the U.S. Department of Housing and Urban Development (HUD). Because HUD backs the loan against default, lenders can accept lower credit scores and down payments as small as 3.5% — but in return every FHA loan carries government mortgage insurance. This calculator turns a home price, down payment, interest rate and term into the numbers that actually land on your closing statement and your monthly bill: the base loan, the financed upfront mortgage insurance premium (UFMIP), the correct annual MIP rate from HUD's table, and the full monthly principal, interest and MIP payment.
It is a payment estimator, not an underwriting tool — it does not check credit, debt-to-income limits or your county's FHA loan limit. For the amortization mechanics behind the monthly payment, see our amortization calculator, and to sanity-check how much house the payment implies you can afford, the house affordability calculator.
How the FHA payment is built, step by step
- Down payment = home price × down-payment %. FHA's floor is 3.5% (credit score 580+) or 10% (scores 500–579).
- Base loan = home price − down payment.
- Upfront MIP (UFMIP) = base loan × 1.75%, financed into the loan, so the amount actually amortized is total loan = base loan + UFMIP.
- Monthly P&I is the standard level payment on the total loan.
- Annual MIP rate is read from HUD's table by term, loan-to-value (LTV) and conforming limit; monthly MIP = base loan × annual MIP rate ÷ 12.
- Total monthly payment = monthly P&I + monthly MIP (before property tax, insurance and HOA).
monthlyPI = totalLoan × r × (1+r)ⁿ / ((1+r)ⁿ − 1), r = annualRate/100/12, n = termYears × 12
Worked example — a $350,000 home, 3.5% down, 6.5% for 30 years
Every figure below comes from the same engine that powers the calculator above, so the article can never drift from the tool.
| Step | Value |
|---|---|
| Home price | $350,000.00 |
| Down payment (3.5%) | $12,250.00 |
| Base loan (price − down payment) | $337,750.00 |
| Upfront MIP (1.75%, financed) | $5,910.63 |
| Total amortized loan | $343,660.63 |
| Loan-to-value ratio | 96.50% |
| Annual MIP rate (HUD table) | 0.55% |
| Monthly principal & interest | $2,172.17 |
| Monthly MIP | $154.80 |
| Total monthly payment (P&I + MIP) | $2,326.97 |
| Total interest over 30 years | $438,320.19 |
| Total P&I + MIP over 30 years | $837,709.57 |
Financing the $5,910.63 UFMIP pushes the amortized balance just above the base loan, and the 0.55% annual MIP adds roughly $155 a month on top of principal and interest. Because this borrower put less than 10% down, that MIP continues for the life of the loan unless they refinance — the single biggest long-run cost difference versus a conventional loan.
The HUD annual MIP rate table (Mortgagee Letter 2023-05)
These are the annual mortgage insurance premium rates the calculator applies, effective for FHA case numbers assigned on or after March 20, 2023. The rate is divided by 12 and charged monthly on the base loan amount.
| Loan term | Base loan vs. conforming limit | LTV | Annual MIP |
|---|---|---|---|
| More than 15 years | At/below limit | ≤ 95% | 0.50% |
| More than 15 years | At/below limit | > 95% | 0.55% |
| More than 15 years | Above limit | ≤ 95% | 0.70% |
| More than 15 years | Above limit | > 95% | 0.75% |
| 15 years or less | At/below limit | ≤ 90% | 0.15% |
| 15 years or less | At/below limit | > 90% | 0.40% |
The 1.75% upfront premium (UFMIP) is separate and unchanged since 2015. To model paying the loan down faster — which shortens how long you carry MIP if you started above 90% LTV — try the mortgage payoff calculator, or add taxes and insurance to see your full escrowed payment with the mortgage calculator with taxes and insurance.
FHA vs. conventional at a glance
| Feature | FHA loan | Conventional loan |
|---|---|---|
| Minimum down payment | 3.5% (score 580+) | 3% (strong credit), else more |
| Minimum credit score | 500–580 | Typically 620+ |
| Mortgage insurance | Always (UFMIP + monthly MIP) | PMI only under 20% down |
| Cancel the insurance? | Only if ≥10% down (after 11 yrs); else life of loan | PMI drops off at 78–80% LTV |

Assumptions and limitations
- The UFMIP is assumed financed into the loan (the common default), not paid in cash at closing.
- Monthly MIP is approximated as base loan × annual MIP rate ÷ 12 held constant for the term. Lenders technically recompute annual MIP off the average outstanding balance each year; this standard online-calculator convention overstates MIP only slightly late in the term.
- The total-cost figure assumes MIP runs for the whole term. It does not model the 11-year MIP cancellation available when the initial down payment was 10% or more (LTV ≤ 90%), which lowers real-world lifetime MIP for those borrowers.
- MIP rates and the $726,200 MIP-table threshold come from HUD Mortgagee Letter 2023-05 and remain in effect for 2026; they are periodically revised, so confirm the current HUD figures before relying on the output for a real transaction.
- The total monthly payment excludes property tax, homeowners insurance and HOA dues, and the tool assumes a fixed-rate, single-family, principal-residence FHA 203(b) loan.
Frequently asked questions
What is an FHA loan and how is it different from a conventional loan?+
An FHA loan is a mortgage insured by the Federal Housing Administration (a part of HUD), which lets lenders offer more lenient credit and down-payment requirements — as little as 3.5% down with a credit score of 580 or higher. In exchange, every FHA loan carries mandatory mortgage insurance (UFMIP + monthly MIP) regardless of down payment size, unlike a conventional loan where private mortgage insurance (PMI) can be avoided entirely with 20% down and cancelled once you reach 78-80% LTV.
What is the minimum down payment for an FHA loan?+
FHA requires 3.5% down for borrowers with a credit score of 580 or above, and 10% down for scores between 500 and 579. Below 500, most lenders won't approve an FHA loan. This calculator's down-payment field defaults to and floors at 3.5%, the standard minimum.
What is UFMIP and do I have to pay it in cash?+
The Upfront Mortgage Insurance Premium (UFMIP) is 1.75% of your base loan amount, charged once at closing on every FHA loan. Most borrowers finance it into the loan rather than paying cash — that's what this calculator assumes, which is why the amortized total loan is slightly larger than your base loan. You can also pay UFMIP in cash to keep your amortized balance (and monthly P&I payment) lower.
How is the monthly FHA mortgage insurance premium (MIP) calculated?+
Monthly MIP = base loan amount x annual MIP rate / 12. The annual MIP rate itself comes from a HUD table keyed by three things: your loan term (more or less than 15 years), your loan-to-value ratio, and whether your base loan is at/below or above the national conforming loan limit. For the common case — 30-year term, more than 95% LTV, loan at/below the conforming limit — the current annual rate is 0.55%.
Can I ever stop paying FHA mortgage insurance?+
Yes, but only if your initial down payment was 10% or more (LTV 90% or lower) — in that case, MIP is automatically cancelled after 11 years. If you put down less than 10% (which most FHA borrowers do), MIP continues for the life of the loan. The only ways out at that point are refinancing into a conventional loan once you have enough equity, or paying off the loan.
What's the difference between UFMIP and monthly MIP?+
UFMIP is a one-time 1.75% charge on your base loan amount at closing, usually financed into the loan. Monthly MIP is an ongoing charge — a percentage of your base loan (looked up from the HUD MIP table) divided by 12 — added to every monthly payment for as long as MIP applies. Both exist on virtually every FHA loan; conventional loans only charge an ongoing PMI and only when the down payment is under 20%.
What is the FHA conforming loan limit and why does it matter?+
The conforming loan limit is the maximum base loan amount HUD treats as 'standard' for the annual MIP table each year (a fixed $726,200 nationwide, set by Mortgagee Letter 2023-05 and unchanged since — still $726,200 in 2026, and separate from the FHFA conforming loan limit that rises each year). Loans above that limit pay a slightly higher annual MIP rate (e.g. 0.75% instead of 0.55% for the >95% LTV, >15-year-term row). This calculator applies the above-conforming row automatically once your base loan amount crosses that threshold.
Why is my loan-to-value (LTV) ratio based on the base loan, not the amount I'm actually financing?+
FHA's MIP table keys off LTV = base loan amount / home price — the loan before UFMIP is added. This is intentional: UFMIP is a financing charge, not part of the property-secured risk HUD is pricing MIP against. So a 3.5% down payment gives you a 96.5% LTV for MIP-table purposes even though your amortized loan balance (after financing UFMIP) is a bit higher than 96.5% of the home price.
How does the loan term (15 vs 30 years) affect FHA mortgage insurance?+
HUD uses two separate MIP tables — one for terms of 15 years or less, one for terms longer than 15 years — and the shorter-term table charges meaningfully lower annual MIP rates at the same LTV (for example, 0.15% vs 0.55% at low LTV). Combined with a shorter amortization period, a 15-year FHA loan carries both less total interest and less lifetime mortgage insurance than an equivalent 30-year loan, at the cost of a higher monthly payment.
Are FHA mortgage insurance rates the same every year?+
No. HUD periodically revises annual MIP rates and the conforming loan limit through Mortgagee Letters — the rates used here reflect Mortgagee Letter 2023-05 (effective March 20, 2023), whose annual MIP rates and $726,200 MIP-table threshold still apply in 2026. Always check the current HUD Mortgagee Letter before finalizing a loan, since HUD can revise them.
Is an FHA loan cheaper than a conventional loan over the life of the mortgage?+
It depends on your credit score and down payment. FHA's mandatory MIP (both upfront and monthly, often for the life of the loan at low down payments) can make it more expensive long-term than a conventional loan with strong credit and 20% down, which pays no mortgage insurance at all. But for borrowers with a lower credit score or a smaller down payment, FHA's lenient qualification and lower monthly MIP rates (versus conventional PMI at the same credit tier) can make it the more affordable — sometimes the only available — path to homeownership.
What's the difference between the FHA loan limit and the conforming loan limit this calculator uses for MIP?+
These are two separate HUD figures that get confused often. The FHA loan limit is the maximum loan size HUD will insure in a given county — it varies county by county and has nothing to do with your MIP rate. The national conforming loan limit is a single, separate nationwide threshold that only decides which row of the annual MIP table applies to your base loan amount (the calculator's 'above-conforming' rows). A loan can sit comfortably under your county's FHA loan limit while still crossing the lower national conforming threshold and paying the higher MIP rate — check both figures with your lender, not just one.
Does this calculator cover FHA 203(k) renovation loans?+
No — this tool models a standard fixed-rate FHA 203(b) purchase loan, the most common FHA product. An FHA 203(k) loan lets you finance renovation costs into the mortgage based on the home's as-repaired value, and it carries its own upfront/annual MIP treatment and underwriting rules that this calculator doesn't reproduce. If you're planning to roll renovation costs into an FHA loan, treat these numbers as a starting point for the purchase-only math, not the full 203(k) picture.
Can I qualify for an FHA loan if my debt-to-income ratio is above the usual guideline?+
Possibly. FHA's standard guideline caps debt-to-income around 31% for housing costs and 43% overall, but lenders can approve higher ratios when 'compensating factors' offset the risk — things like several months of cash reserves, little change from your current housing payment, or strong residual income after expenses. This calculator only estimates the payment itself; it doesn't evaluate your income, debts, or whether a lender would approve you at a higher ratio.
