Prepayment Premium Calculator
Paying off a loan early often sounds like the best way to save money on interest. However, many loan agreements include a prepayment premium (or prepayment penalty). This fee compensates lenders for the lost interest they would have earned had the loan remained active until maturity.
The Prepayment Premium Calculator helps borrowers and businesses calculate the extra cost of paying off a loan early. By using this tool, you can make informed financial decisions about whether prepaying a loan or refinancing is beneficial.
What Is a Prepayment Premium?
A prepayment premium is a charge imposed by lenders when borrowers repay a loan before the scheduled due date.
- For borrowers – It’s an added expense when closing a loan early.
- For lenders – It offsets lost future interest earnings.
- For financial planners – It’s a critical factor when comparing refinancing vs. continuing a loan.
Formula for Prepayment Premium
The formula varies depending on the loan contract. A common calculation is: Prepayment Premium=Outstanding Loan Balance×Prepayment Premium Rate\text{Prepayment Premium} = \text{Outstanding Loan Balance} \times \text{Prepayment Premium Rate}Prepayment Premium=Outstanding Loan Balance×Prepayment Premium Rate
Where:
- Outstanding Loan Balance = Remaining principal at the time of prepayment.
- Prepayment Premium Rate = Percentage charged by the lender (e.g., 2%).
Some contracts may use interest differentials or yield maintenance methods.
