Choosing between an FHA and a conventional loan is one of the first decisions a buyer faces, and it is rarely as simple as picking the lower rate. FHA loans, backed by the Federal Housing Administration, are designed for buyers with modest down payments and credit profiles, while conventional loans follow private-market standards and reward stronger applications with better terms. The right choice depends on your down payment, your credit score, how long you will stay, and how the two loans' insurance structures affect your total cost over time.
The Core Difference in a Sentence
FHA loans are government-insured and accept smaller down payments and lower scores but charge mortgage insurance for most of the loan's life; conventional loans are private and reward larger down payments and stronger credit with lower costs and cancellable insurance. That single structural difference drives almost every comparison between them. Our loan guides and calculators let you see the actual monthly and lifetime cost of each for your situation rather than guessing from the headline rate.
Both loan types can be fixed or adjustable, both require taxes and insurance in escrow, and both are widely available. The divergence is in eligibility and insurance, not in the basic mechanics of the mortgage. Understanding that the decision is really about the insurance and the entry barrier — not about the rate alone — prevents the common error of choosing FHA for its low down payment without counting the insurance it carries for years.
Down Payment Minimums
FHA requires as little as 3.5% down with a 580 score, and sometimes 10% down with a 500 score, which is the lowest barrier among mainstream loans. Conventional loans go as low as 3% for certain first-time programs but more commonly 5%, and they price more harshly below 20% via mortgage insurance. For a buyer with almost no savings, FHA is often the only door into ownership, which is its core strength and the reason it exists.
The low FHA minimum is attractive, but it comes with a catch: the smaller the down payment, the larger the loan and the more permanent the insurance. A 3.5% FHA down payment means a 96.5% loan-to-value that carries mortgage insurance for the life of the loan in most cases. A 5% conventional down also carries PMI, but it cancels at 20% equity, so the long-run cost can be far lower despite the slightly higher entry barrier. The calculator compares the two payments so the trade is explicit.
Credit Score Requirements
FHA is more forgiving of credit history. Scores down to 580 qualify at 3.5% down, and some lenders go lower with a larger down payment. Conventional loans generally want 620 or higher, and the best rates require 740 plus. For a buyer rebuilding credit, FHA is often the realistic path, while a buyer with a strong score gains little from FHA and usually does better with conventional pricing and cancellable insurance.
The score also affects the insurance cost on each. On FHA, the mortgage insurance premium is set by the program and barely moves with your score, whereas conventional PMI is priced by credit band and can be much cheaper for high scorers. So a strong-credit buyer pays relatively more for FHA insurance than a weak-credit buyer does, making conventional the better deal as your score rises. The PMI Estimator shows the conventional premium at your band so you can see the gap.
The Mortgage Insurance Divide
This is the crux. FHA charges an upfront mortgage insurance premium plus an annual premium that, for most loans with small down payments, cannot be removed for the life of the loan. Conventional PMI cancels at 20% equity by request and automatically at 22%. Over a long stay, FHA's permanent insurance can cost tens of thousands more than conventional PMI you drop after a few years, which often flips the cheaper choice toward conventional even with a higher rate.
The upfront FHA premium is financed into the loan, so you pay interest on it too, adding to the long-run cost. Conventional loans have no upfront premium; the monthly PMI is the only insurance cost, and it ends. For a buyer planning to stay decades, this structural difference usually dominates the rate comparison. Our guides spell out the FHA premium rules, and the calculators show the all-in monthly and lifetime cost so the insurance divide is quantified, not just described.
Total Cost Over Your Stay
Because the insurance behaves so differently, the total cost depends heavily on how long you keep the loan. For a short stay of a few years, FHA's low entry can win because you do not keep the loan long enough for the permanent insurance to outweigh the easier qualifying. For a long stay, conventional's cancellable insurance almost always wins. The calculator lets you model both at your expected tenure, turning a rate-only comparison into a true cost comparison that respects your timeline.
There is also a hybrid path: use FHA to get in with a tiny down payment, then refinance to conventional once you reach 20% equity and drop the insurance. This captures FHA's low entry and conventional's low long-run cost, but it costs refinance fees and assumes rates and values cooperate when you refinance. The refinance calculator models the break-even on that strategy, so you can decide whether the FHA-then-refinance plan beats going conventional from the start given your savings and stay.
Rate and Fee Comparison
FHA rates are often competitive with conventional rates at the same term, but the total cost differs because of the insurance and the upfront premium. A lender might quote a lower FHA rate that looks better, yet the annual premium makes the effective monthly cost higher for a long stay. Always compare the full payment — principal, interest, and all insurance — not the rate alone. The mortgage calculator shows the FHA payment with its premium versus the conventional payment with PMI so the real difference is clear.
Fees also differ. FHA's upfront premium is unique to that program; conventional loans may have an upfront fee only if you choose lender-paid mortgage insurance via a higher rate. Title, appraisal, and closing fees are similar across both. The calculator isolates the insurance and premium pieces, and the Loan Estimate from each lender shows the fees, so you can stack the rate, the insurance, and the fees into one comparison that reflects what you will actually pay, not the marketing rate.
Which Should You Choose?
Choose FHA if your score is below conventional thresholds, your down payment is very small, and you may not stay long enough for the insurance to outweigh the easier entry. Choose conventional if you have at least 5% down, a 620-plus score, and expect to stay long enough for cancellable PMI to beat FHA's permanent premium. For a 20%-plus down payment, conventional is almost always better. The calculators make the call with your numbers rather than a rule of thumb.
The decision also depends on your plan to build equity. If you intend to pay down the loan or the home will appreciate so you reach 20% equity fast, conventional's cancellable insurance rewards that progress, while FHA's insurance ignores it. The PMI Estimator projects conventional cancellation; the FHA rules are fixed. Pairing the two views shows whether your equity plan makes conventional clearly cheaper, which for most steady owners it does, even when FHA's entry looks easier today.
Frequently Asked Questions
Is FHA or conventional better for a small down payment?
FHA allows 3.5% down and is easier to qualify for, but its mortgage insurance often lasts the life of the loan, costing more over time. Conventional at 3% or 5% down drops PMI at 20% equity. For long stays, conventional often wins on total cost; for low scores, FHA may be the only option.
Can I avoid mortgage insurance with FHA?
Generally no. FHA charges an upfront and annual mortgage insurance premium that typically cannot be removed for the life of the loan if the down payment is small. This is a key drawback versus conventional PMI, which cancels at 20% equity. Our PMI Estimator and guides explain the difference in total cost.
Which loan has lower credit requirements?
FHA accepts scores as low as 580 with 3.5% down and sometimes 500 with 10% down, while conventional loans usually want 620 or higher. For buyers with thinner credit, FHA is often the accessible path, though the rate and insurance may be higher.
Are FHA loans more expensive overall?
Upfront, FHA can be cheaper to enter, but the permanent mortgage insurance often makes it more expensive over a long hold. The total cost depends on your stay, score, and down payment. Comparing both with our calculators shows which is cheaper for your specific numbers.
Can I refinance out of FHA later?
Yes. Many borrowers use FHA to get in, then refinance to a conventional loan once they have 20% equity to drop the mortgage insurance. This is common, but it costs refinance fees and assumes rates and values cooperate. The refinance calculator models the break-even on that move.
Which is better for a large down payment?
With 20% or more down, conventional is usually better: no mortgage insurance, often a lower rate, and simpler rules. FHA's advantages shrink as the down payment grows, so conventional becomes the clear choice once you clear 20% equity.
