You're probably tired of seeing that monthly FHA mortgage insurance premium (MIP) eat into your bank account. It’s frustrating. You’ve been paying on time, your home value has likely ticked up over the last few years, and yet, there’s that extra $150 or $250 basically going into a black hole every single month. Honestly, for most people, the fha to conventional refinance calculator is the only tool that actually matters when trying to figure out if they're being ripped off by staying in their current loan.
But here’s the thing. Most people use these calculators wrong because they focus entirely on the interest rate.
A lower interest rate is great, don't get me wrong. But if you’re moving from an FHA loan to a conventional one, the real prize is the removal of the Life-of-Loan mortgage insurance. With FHA, unless you put down 10% or more at the start, that insurance sticks around until the day you pay off the house or sell it. Moving to a conventional loan lets you drop that weight the second you hit 20% equity. It's a massive shift in how your monthly payment is structured.
Why the fha to conventional refinance calculator is more than just a math tool
When you pull up a calculator, you’re looking for a "break-even point." That’s the fancy way of saying "how long until the money I save on my monthly payment covers the thousands of dollars I just spent on closing costs."
If your closing costs are $6,000 and you save $200 a month, you need 30 months just to get back to zero. If you plan on moving in two years? You just handed the bank a gift. You lost money.
The complexity comes from the Private Mortgage Insurance (PMI) on the conventional side. Unlike FHA, where everyone pays roughly the same rate for MIP regardless of their credit score, conventional PMI is incredibly sensitive to your FICO score. If your credit is a 640, your conventional PMI might actually be more expensive than your FHA insurance. If you’re at a 760? It’ll be pennies by comparison.
The phantom costs people forget to plug in
Let’s talk about the appraisal. You can’t just tell the bank "I think my house is worth more." They’re going to send someone out, and you're going to pay $500 to $800 for the privilege. If the appraisal comes back low and shows you only have 15% equity instead of 20%, you’re still stuck paying PMI on that new conventional loan.
It might still be cheaper than FHA MIP because conventional PMI eventually falls off automatically, but the calculator needs to reflect that reality.

Another big one? Escrow resets. When you refinance, your old lender sends you a check for your old escrow balance, but you have to fund a brand new escrow account with the new lender upfront. It’s not a "cost" per se—it’s your money—but it’s a massive cash-out-of-pocket moment that catches people off guard.
Understanding the 20% equity threshold
The magic number is 20. If you have 20% equity, you skip PMI entirely. This is the "Holy Grail" of the fha to conventional refinance calculator results.
How do you get there? Two ways. Either you’ve paid down the principal, or the market has done the heavy lifting for you. In many parts of the country, home prices have appreciated so rapidly that people who bought with 3.5% down just two or three years ago suddenly find themselves sitting on 25% equity.
Wait.
Check your math before you jump. If you have a 3% interest rate on your FHA loan and current market rates are 6.5%, dropping the $150 mortgage insurance might not save you money. You’d be trading a low-interest rate for a high one. In that specific case, even with the "annoying" MIP, the FHA loan is actually the better deal. You have to look at the total "effective rate."
The FICO factor
Conventional loans love high credit scores. FHA loans don't really care. This is a fundamental divide in the mortgage world.
- FHA (Federal Housing Administration): They are the "insurers of last resort" for people with dings on their credit. They charge you a flat rate for insurance because they’re taking a bigger risk.
- Conventional (Fannie Mae/Freddie Mac): These are private-sector driven. They use "risk-based pricing."
If your credit score has jumped from a 620 to a 720 since you bought your house, a conventional loan will reward you with a much lower PMI rate and a better interest rate. If your score stayed low, the conventional loan might actually penalize you. It’s weird, but it’s true. A conventional loan with mediocre credit can sometimes be more expensive than an FHA loan.

Real world scenario: The "Is it worth it?" test
Let's look at a hypothetical. You owe $300,000 on a house that is now worth $380,000.
Your current FHA loan has an interest rate of 4.5%. Your monthly MIP is $210.
Total principal, interest, and insurance = $1,730 (excluding taxes/homeowners insurance).
You look at a conventional refinance. The current rate is 5.5%.
Since you have about 21% equity ($80,000 / $380,000), you won't have any PMI.
The new payment for principal and interest is $1,703.
On paper, you're saving $27 a month.
Wait. $27?
That's it?
If the closing costs for that refinance are $5,000, it would take you 185 months—over 15 years—to break even. In this scenario, the fha to conventional refinance calculator would screaming at you to stay put. Even though the FHA loan has "scary" mortgage insurance, the lower interest rate makes it the winner.
Now, change one variable. If your FHA rate was 6.5% and you could refinance into a 5.5% conventional loan, the savings would be massive—likely $400+ a month. That’s a "no-brainer" move.
Steps to take before hitting "Calculate"

- Check your current mortgage statement: Find exactly what you pay for "MIP" or "Mortgage Insurance." Don't guess.
- Estimate your home's value: Look at recent sales of similar houses in your specific neighborhood. Not Zillow "Zestimates," which can be wildly off, but actual sold prices.
- Check your credit score: Use a free tool to see your FICO 2, 4, or 5 scores. These are the "mortgage scores" and they are usually lower than the "VantageScore" you see on apps like Credit Karma.
- Call a local broker: Ask for a "Loan Estimate" (LE). This is a standardized federal form that breaks down every single penny of the proposed refinance.
The "Net Tangible Benefit" rule
Lenders are actually legally required in many cases to prove that a refinance helps you. This is called the "Net Tangible Benefit." They shouldn't be moving you into a loan that puts you in a worse position just to make a commission. However, their definition of "benefit" might be different than yours. They might see "lowering the monthly payment by $10" as a benefit, even if it adds 10 years to your mortgage term.
Be careful.
If you are 5 years into a 30-year mortgage and you refinance into a brand new 30-year mortgage, you just reset the clock. You'll be paying interest for a total of 35 years. A good fha to conventional refinance calculator should show you the total interest paid over the life of the loan, not just the monthly savings. Sometimes, it's smarter to refinance into a 20-year or 15-year conventional loan to make sure you're actually building wealth, not just chasing a lower monthly bill.
Moving forward with the data
Refinancing isn't a "set it and forget it" thing. It’s a tactical move. If the numbers don't work today, they might work in six months if rates drop or your home value climbs another 5%.
The most actionable thing you can do right now is find your "Loan-to-Value" (LTV) ratio. Divide your current loan balance by the estimated value of your home. If that number is 0.80 (80%) or lower, you are in the prime zone for a conventional refinance. If it's 0.90, you'll still have PMI, but it might be cheaper than what you have now.
Check the "Upfront Mortgage Insurance Premium" (UFMIP) as well. When you got your FHA loan, you likely paid 1.75% of the loan amount upfront. You don't get that back. It’s a sunk cost. Don't let the "I already paid for FHA" feeling stop you from switching if the conventional math makes sense today.
Focus on the math, ignore the sales pitches, and remember that the goal isn't just a lower payment—it's more equity in your pocket.
Actionable Next Steps:
- Pull your actual credit report: Ensure there are no errors that could artificially inflate your conventional PMI quotes.
- Calculate your LTV: If you are at 78-82%, an appraisal is the "swing" factor that determines your success.
- Compare the "Total Cost over 5 Years": Ask lenders to show you the total spend (payments + closing costs) for both your current loan and the new one over a five-year window. This is usually the most honest way to see if a refinance is actually a win.
