What is a mortgage prepayment penalty?

A prepayment penalty is a fee charged by some lenders when you pay off your mortgage early — whether by refinancing, selling, or making a large lump-sum payment. It compensates the lender for lost interest income. Most conventional loans originated after 2014 do not have prepayment penalties.

How is a prepayment penalty calculated?

Common methods: (1) Percentage of remaining balance — e.g., 2% of $280,000 = $5,600. (2) Months of interest — e.g., 6 months × monthly interest at 5.5% on $280,000 = $7,700. (3) Declining scale — starts at 5% in year 1 and decreases 1% per year until zero.

Should I pay a prepayment penalty to refinance?

Calculate the break-even: divide the penalty plus closing costs by your monthly savings from the lower rate. If you'll keep the new loan longer than the break-even period, it makes financial sense. Generally, break-even under 3 years = worth it; over 5 years = think carefully.

Is a prepayment penalty tax deductible?

Yes, prepayment penalties on your primary or secondary residence are deductible as mortgage interest in the year paid, just like regular mortgage interest. For investment properties, it may be deductible as a business expense. Consult a tax advisor for specifics.

What is the difference between hard and soft prepayment penalties?

A hard prepayment penalty applies to all payoffs — selling, refinancing, or early paydown. A soft penalty only applies to refinancing, not to selling the home. If you have a soft penalty and plan to sell rather than refinance, you may owe nothing.

How to Use This Prepayment Penalty Calculator

Enter your loan details and penalty structure to calculate the exact cost of paying off your mortgage early:

Current Balance: Your remaining loan balance — not the original amount. Check your most recent mortgage statement.
Penalty Type: Review your loan documents or contact your servicer to confirm which type applies. Three main types exist.
% of Balance: A flat percentage applied to your remaining balance. Common in commercial loans and some adjustable-rate mortgages.
Months of Interest: A set number of months of interest at your current rate. 3 and 6 months are most common.
Declining Scale: The penalty percentage decreases each year until it reaches zero. Most favorable to borrowers who can wait.

Three Types of Prepayment Penalties

Penalty Comparison on a $280,000 Balance at 5.5%

Type	Structure	Penalty Amount
% of Balance	2% of remaining balance	$5,600
Months of Interest	6 months of interest	$7,700
Declining Scale (Yr 3)	5-4-3-2-1-0%, currently year 3 = 3%	$8,400

The "cheapest" penalty depends on your loan balance and interest rate. Always calculate all three if you're unsure which applies.

Step-Down / Declining Penalties Explained

A declining prepayment penalty (also called "step-down") is common in USDA loans, some FHA loans, and commercial mortgages. It might read: "5-4-3-2-1" — meaning 5% in year 1, 4% in year 2, down to 0% after year 5.

If you're approaching a penalty reduction date, even waiting 1-2 months can save thousands. A $300,000 loan dropping from 3% to 2% saves $3,000.

Do Conventional Mortgages Have Prepayment Penalties?

Most conventional mortgages originated after the 2014 Qualified Mortgage (QM) rules do not have prepayment penalties. Dodd-Frank restrictions significantly limited prepayment penalties on QM loans:

No prepayment penalties on fixed-rate QM loans after 3 years
Penalties capped at 2% in years 1-2 and 1% in year 3 for adjustable-rate loans
Many lenders eliminated penalties entirely to qualify for the QM safe harbor

Where prepayment penalties still appear:

USDA and some FHA loans (declining penalties)
Commercial real estate loans
Hard money loans
Some non-QM or portfolio loans
Older loans originated before 2014
Some adjustable-rate mortgages

When Does It Make Sense to Pay the Penalty?

The decision to pay a prepayment penalty comes down to the break-even calculation:

Break-Even Months = (Penalty + Closing Costs) / Monthly Savings

Example:
Penalty = $5,600 · Closing costs = $4,000 · Total = $9,600
Monthly savings from refinancing = $250/month
Break-even = $9,600 / $250 = 38.4 months (3.2 years)

If you plan to stay 5+ years: Pay the penalty and refinance
If you'll move in 2 years: Keep the current loan

As a rule of thumb, paying the penalty makes sense if your break-even period is under 3 years and you plan to hold the new loan for at least that long.

Frequently Asked Questions

Check your original loan documents — specifically the Note and the Prepayment Rider, if any. Most conventional loans originated after 2014 do not have prepayment penalties. If your loan is FHA, VA, or USDA, check with your servicer. Commercial loans almost always have some form of prepayment penalty.

Prepayment penalties are contractual obligations — you cannot typically "negotiate" out of them after the fact. However, if you're originating a new loan, you can ask lenders to remove the prepayment penalty clause, sometimes in exchange for a slightly higher rate. Always negotiate this upfront.

A hard prepayment penalty applies to ALL forms of payoff — refinancing, selling, or paying off early. A soft prepayment penalty applies only to refinancing, not to selling the home. If you have a soft prepayment penalty and are planning to sell (not refinance), you may not owe anything.

Yes — for your primary or secondary residence. The IRS allows prepayment penalties to be deducted as mortgage interest in the year paid. For investment properties, it may also be deductible as a business expense. Consult a tax advisor for your specific situation.

Yield maintenance is a type of commercial prepayment penalty designed to compensate the lender for lost interest income. The penalty = the present value of remaining payments discounted at a treasury rate. It can be very large when interest rates drop significantly, and it protects lenders more than simple percentage-based penalties.
