FHA vs Conventional Loan With 20% Down: Payment Comparison
When comparing an FHA vs conventional loan with 20% down, the loan with the lower interest rate may not have the lower total monthly payment. Many borrowers assume that the mortgage with the lowest interest rate must be the best option. However, the interest rate is only one part of the loan’s total cost.
Consider this analysis I prepared for one of my borrowers:
Loan detail | Scenario |
Purchase price | $575,000 |
Down payment | 20%, or $115,000 |
Base loan amount | $460,000 |
Credit score | 700 |
Debt-to-income ratio | 45% |
Loan term | 30-year fixed |
The borrower was offered a lower interest rate on the FHA loan, but the conventional loan still produced the lower initial monthly payment.
FHA versus conventional payment comparison
FHA financing
Interest rate: 5.710%
Principal and interest: $2,719.53
Monthly FHA mortgage insurance: $190.74
Total financing payment: $2,910.27
Conventional financing
Interest rate: 6.324%
Principal and interest: $2,854.48
Private mortgage insurance: $0
Total financing payment: $2,854.48
Based on the payments shown, the conventional loan saves the borrower $55.79 per month, or approximately $669.48 during the first 12 months.
Although the FHA interest rate is more than half a percentage point lower, FHA mortgage insurance causes the total payment to be higher.
Why conventional financing is the better fit in this scenario
1. A 20% down payment eliminates conventional mortgage insurance
Private mortgage insurance is generally associated with conventional loans exceeding 80% loan-to-value. Because this borrower is making a full 20% down payment, the conventional loan begins at an 80% LTV and does not require monthly PMI.
This is one of the main financial advantages of putting 20% down.
FHA financing works differently. FHA generally charges mortgage insurance regardless of whether the borrower puts down 3.5%, 10% or 20%.
2. FHA adds an upfront mortgage insurance premium
Most FHA purchase loans require a 1.75% upfront mortgage insurance premium, commonly called UFMIP. HUD permits this premium to be financed into the mortgage balance.
In this example:
Base FHA loan: $460,000
Upfront FHA premium: $8,050
FHA loan after financing UFMIP: $468,050
The conventional loan starts with a principal balance of approximately $460,000, while the FHA borrower begins with approximately $8,050 more debt when the upfront premium is financed.
That additional amount also accrues interest as part of the FHA loan.
3. FHA still requires monthly mortgage insurance
For a qualifying FHA mortgage with a term longer than 15 years and an original LTV of 90% or less, the annual mortgage insurance premium is generally assessed for 11 years. The applicable annual MIP rate for a loan of this size is currently 0.50% of the applicable outstanding balance.
Therefore, even though this borrower is putting down 20%, the borrower could still pay FHA mortgage insurance for approximately 11 years.
Building additional equity does not automatically cancel the FHA insurance ahead of that scheduled period. The borrower could potentially refinance into a conventional mortgage later, but refinancing would require a new qualification, appraisal and closing costs.
4. A 700 credit score is generally considered good credit
FHA financing can be especially valuable for borrowers who need:
A smaller down payment
More flexible credit requirements
Greater underwriting flexibility
Assistance qualifying after previous credit challenges
However, those advantages may be less valuable to a borrower with a 700-credit score, a 20% down payment, and an approvable conventional loan.
In this scenario, the borrower would incur FHA mortgage insurance even though the borrower is contributing substantial equity at closing and has a solid credit profile. By comparison, a conventional loan at 80% loan-to-value generally does not require monthly private mortgage insurance.
The borrower’s 45% debt-to-income ratio must still be evaluated through automated underwriting and a complete review of the loan application. However, when the borrower qualifies for both programs, conventional financing may provide a more cost-efficient structure despite having a higher interest rate.
Do not compare mortgage rates by themselves
The FHA rate in this example is lower, but the FHA loan also includes:
An $8,050 upfront insurance premium
A higher loan balance if the premium is financed
Approximately $190.74 in initial monthly mortgage insurance
A higher initial monthly financing payment
The Consumer Financial Protection Bureau explains that the interest rate does not include all loan expenses. APR provides a broader measurement because it incorporates the interest rate and certain additional charges. Borrowers should also compare the five-year cost shown on Page 3 of each Loan Estimate.
A proper loan comparison should evaluate:
Interest rate and APR
Discount points
Lender fees and credits
Monthly mortgage insurance
Upfront mortgage insurance
Beginning loan balance
Cash required at closing
Five-year borrowing cost
Expected length of homeownership
Could FHA still make sense?
Possibly. The FHA loan has a significantly lower note rate in this example. After the scheduled FHA mortgage insurance period ends, its continuing principal-and-interest payment will remain lower than the conventional payment, assuming the borrower keeps the original loan.
Therefore, the final decision should also account for how long the borrower expects to own the property and retain the mortgage.
FHA may also be appropriate when its underwriting flexibility is necessary for approval. But a borrower should not select FHA solely because its advertised interest rate is lower.
The Titanium Mortgage approach
At Titanium Mortgage, we do not simply recommend a loan with the lowest rate. We compare the complete financing structure to determine which option provides the borrower with the best overall result.
In this scenario, the conventional loan offers:
No monthly mortgage insurance
No FHA upfront insurance premium
A lower beginning loan balance
A lower initial monthly payment
Approximately $669 in first-year payment savings based on the quoted figures
For a borrower with a 700-credit score and 20% down, conventional financing is likely the stronger initial option provided the borrower and property satisfy conventional underwriting requirements.
The best mortgage is not necessarily the one with the lowest rate. It is the one that best supports the borrower’s payment, equity, financial goals and expected ownership period.
