FHA vs Conventional Loan: Which One Actually Costs You Less?

Most people compare an FHA loan and a conventional loan by looking at two monthly payments and picking the smaller one. That comparison is not wrong, exactly. It is just answering a much smaller question than the one you are actually asking.

The two loans are not priced the same way, and the difference is not really the interest rate. FHA frequently carries the lower note rate of the two. What FHA does instead is charge you an insurance premium that, on most modern FHA loans, you will still be paying in year 29 — long after you owe less than half of what the house is worth. Conventional mortgage insurance, by contrast, is designed to die. You can demand its cancellation at 80% loan-to-value and the servicer must switch it off by itself at 78%.

That single structural asymmetry is worth more money than any rate shopping you will ever do. Below is what it looks like in dollars.

The two loans, side by side

Everything here is structure, not pricing. The exact premiums and loan limits change; the mechanics have been stable for years.

Read the “how long the insurance lasts” row twice. It is the entire article.

Mortgage insurance is the whole ballgame

Both loans make you insure the lender against your own default when you put down less than 20%. They just collect the money in almost opposite ways.

FHA: an upfront fee, then a premium that usually never ends

FHA charges two premiums. The upfront mortgage insurance premium (UFMIP) is a percentage of the base loan amount, paid at closing — and almost everyone finances it, meaning it gets added to the loan balance and you then pay interest on it for 30 years. The annual MIP is a percentage of the outstanding balance, billed monthly.

Here is the part that decides the whole comparison: on a 30-year FHA loan with less than 10% down, the annual MIP is charged for the entire loan term. Not until 80% LTV. Not until you have equity. For the life of the loan. Put 10% or more down and it drops off after about 11 years — which is a real benefit, and also a strange one, because a borrower with 10% to spare should usually be looking hard at conventional anyway.

Do not take a specific MIP percentage from an article, including this one. The premiums have been adjusted several times and are tiered by loan size, term and LTV. Get the current figures in writing from your lender.

Conventional: PMI you can actually kill

Private mortgage insurance is priced on your credit score and your LTV, which is why it swings so wildly — a cheap rounding error for a 760 borrower and a punishing monthly charge for a 640 one. But it has an expiry date built into federal law: you may request cancellation at 80% LTV of the original value, and the servicer must automatically terminate it at 78% provided you are current on payments. Many servicers will also cancel early on a new appraisal if the home has appreciated, which in a strong market can end PMI in 4–6 years instead of 11.

The worked comparison: one house, two loans

Everything below is illustrative. The rates and premiums are plausible for a mid-2020s market but they are assumptions, not quotes.

Assumptions: purchase price $350,000; 5% down ($17,500) on both loans, so the down payment is not doing any of the work; 30-year fixed; no extra payments; no home appreciation; taxes, hazard insurance and HOA excluded because they are identical on both sides. Borrower has a 740 credit score — that is, they can genuinely choose.

• FHA: note rate 6.25%. Base loan $332,500, plus a financed UFMIP of $5,819, giving a starting balance of $338,319. Annual MIP assumed at 0.55% of the balance. MIP runs all 30 years, because the down payment is under 10%.
• Conventional: note rate 6.375% — a quarter point worse than FHA, which is realistic. Loan $332,500. PMI assumed at 0.35% annually, which is what a 740 file buys you. PMI ends when the loan amortizes to 78% LTV.

Look at what the interest column is doing. FHA’s lower rate genuinely works: over 30 years the FHA borrower pays about $2,700 less interest than the conventional borrower, despite starting with a bigger balance. FHA wins the rate fight.

And then loses the war by $29,100, because that is how much more mortgage insurance it collects.

$42,000

After ten years, the loans have already diverged

Ten years in — roughly when the average buyer sells or refinances anyway — the FHA borrower has paid about $10,700 more to borrow the same money, owes about $4,000 more (they financed the UFMIP), and is facing another 20 years of MIP. The conventional borrower’s PMI is about to switch itself off, taking $97 a month with it, permanently.

That $10,700 is not the headline number. The $26,400 lifetime gap is not really the headline number either. The headline is that one of these costs has an end date and the other one doesn’t.

When FHA is genuinely the right loan

Now run the same house for a borrower with a 640 score. FHA’s premium barely moves. Conventional’s does — violently — because PMI and conventional rate adjustments are both priced off the score.

FHA wins by roughly $63,900 over the life of the loan and by $307 a month right now. It is not close. And this understates the case, because at a 640 score with 95% LTV, the mortgage insurance companies may simply decline to write the policy at all — in which case the conventional column does not exist and FHA is the only door.

So the honest rule is not “FHA is expensive.” The honest rule is:

• Thin file, low score, recent derogatories, or a debt-to-income ratio conventional won’t stomach — FHA is doing exactly the job it was built for, and it is doing it cheaply.
• 720+ score, clean file, stable income — you are volunteering to pay tens of thousands of dollars for an insurance policy you didn’t need.

Since the whole decision hinges on a three-digit number, it is worth understanding what actually moves it. Our guide to borrowing with bad credit covers what lenders read in a thin file and what genuinely repairs it. And because debt-to-income is the second gate — the one that quietly kills more mortgage applications than credit score does — anyone carrying education debt should look at how their federal student loan repayment plan reports a monthly payment. Moving to a plan with a lower reported payment can change your DTI and, with it, your approval.

When FHA is a trap

The trap is not FHA itself. It is FHA chosen by default, on autopilot, by someone who never priced the alternative — usually because the FHA payment came back lower and the conversation ended there.

Watch for these:

• You would qualify conventional but nobody checked. If your score is above 700, insist on seeing both quotes with the mortgage insurance broken out as a line item, not folded into a single monthly number.
• You put 10% or more down on FHA. You just bought the loan whose MIP expires after 11 years — but a 10% down payment is often enough to get respectable conventional pricing with PMI that dies at 78% LTV. Price it.
• You are counting on refinancing. See below. It is a plan, not a guarantee.
• You financed the UFMIP without noticing. It went into the balance. You will pay interest on it for 30 years, and it made your starting LTV worse, which pushes your PMI-equivalent milestones further out.

The “FHA now, refinance to conventional later” play

This is a real strategy and it is not a bad one. It goes: take the FHA loan today because your credit or your DTI can’t clear the conventional bar, spend two or three years fixing both, then refinance into a conventional loan — which kills the MIP dead and, if rates cooperate, cuts the rate too.

When it works, it works well. In the illustration above, refinancing out of FHA at year 3 would eliminate roughly $36,000 of remaining MIP. That is a genuine, large number and it justifies a lot of effort.

What has to be true for it to work

Four things, all at once, on a day of the market’s choosing:

1. Your credit has to have actually improved. Not “I’ve been paying on time.” Improved enough to clear conventional’s pricing tiers, which is a different and higher bar.
2. Your home has to have held or gained value. A conventional refinance is priced off an appraisal. If the appraisal comes in low, you either bring cash or you stay on FHA — still paying MIP.
3. Rates have to be tolerable. You are not entitled to today’s rate in three years. If rates are 2 points higher, the MIP saving gets eaten alive by the new note rate and the refinance stops making sense.
4. You have to be able to pay for it. A refinance is a new loan with new closing costs — realistically several thousand dollars. Rolling them into the balance is possible and it is not free.

The mechanics of running that break-even properly — new payment, new amortization clock, costs recovered over how many months — are laid out in our complete guide to refinancing a mortgage. Do that arithmetic before you take the FHA loan, not after.

The risks nobody prices in

Resetting the clock. Refinancing into a fresh 30-year loan at year 4 means you have signed up for 34 years of payments on this house. The monthly payment drops; the total interest can quietly go up. Interest is a function of balance and time, and you just bought more time.

Your DTI can get worse, not better. People do not spend three years standing still. They buy a car, they consolidate something, they take a new card. Any of it can push your DTI back over the line on the day you apply — including moves that look financially responsible in isolation. If you are stacking a car payment on top of a mortgage you intend to refinance, pre-approval on the auto loan at least tells you what the payment will be before it lands on your credit report.

Consolidation is not always a fix. A debt consolidation loan can lower your monthly obligations and help your DTI — or it can add a new installment payment and hurt it, depending on what it replaces. Model it before you assume it clears the path.

How to decide, in about ten minutes

Ask your lender for both quotes on the same property, on the same day, and demand that the mortgage insurance appears as its own line — upfront and monthly. Then do three things:

1. Add the upfront fee to the loan cost. FHA’s UFMIP is real money and financing it does not make it disappear; it makes it expensive.
2. Multiply the monthly mortgage insurance by the number of months it will actually run. For FHA at under 10% down, that number is 360. For conventional, it is however many months it takes to amortize to 78% — usually somewhere around 130, sooner if the home appreciates and your servicer accepts a new appraisal.
3. Compare total interest plus total mortgage insurance. Not the payment. Never the payment.

If FHA still wins after that, take it without a shred of guilt — it is a well-designed program and for a large group of borrowers it is the cheapest mortgage in the country. If it loses, you have just found the most expensive $67 a month you were ever offered.
