Calculation Method:

Many loan agreements—especially mortgages, corporate loans, and bonds—include a prepayment premium (sometimes called a prepayment penalty). This is a fee charged when a borrower pays off all or part of a loan before the scheduled maturity date.

While prepayment helps borrowers save on future interest costs, lenders may lose expected income. To offset this, they impose a prepayment premium.

The Prepayment Premium Calculator makes it simple to determine how much a borrower would owe if they decide to repay early. By entering the loan balance, penalty rate, and other key inputs, the calculator instantly shows the cost of prepaying—helping you make better financial decisions.

What Is a Prepayment Premium?

A prepayment premium is a financial charge imposed by a lender when a borrower pays off part or all of a loan earlier than agreed.

It is common in:

Corporate debt agreements
Commercial real estate loans
Mortgage contracts
Bond indentures

Prepayment premiums are designed to protect lenders from losing out on expected interest income.

Formula for Prepayment Premium

The most common calculation is: Prepayment Premium=Outstanding Loan Balance×Prepayment Penalty Rate\text{Prepayment Premium} = \text{Outstanding Loan Balance} \times \text{Prepayment Penalty Rate}Prepayment Premium=Outstanding Loan Balance×Prepayment Penalty Rate

For example:

Loan balance = $100,000
Penalty rate = 2%

Prepayment Premium=100,000×0.02=2,000\text{Prepayment Premium} = 100,000 \times 0.02 = 2,000Prepayment Premium=100,000×0.02=2,000

The borrower would pay $2,000 as a prepayment premium.

Practical Examples

Example 1 – Mortgage Loan

Outstanding balance: $150,000
Prepayment penalty rate: 3%

Prepayment Premium=150,000×0.03=4,500\text{Prepayment Premium} = 150,000 \times 0.03 = 4,500Prepayment Premium=150,000×0.03=4,500

Example 2 – Corporate Loan Agreement

Remaining debt: $1,000,000
Prepayment premium: 2%

Prepayment Premium=1,000,000×0.02=20,000\text{Prepayment Premium} = 1,000,000 \times 0.02 = 20,000Prepayment Premium=1,000,000×0.02=20,000
