What Is a Home Loan Refinance?
A home loan refinance means replacing your existing mortgage with a new one — usually with better terms such as:
- Lower interest rate
- Reduced monthly payment
- Different loan duration
- Better repayment structure
People refinance when market interest rates drop or when their credit score improves, allowing them to qualify for better loan conditions.
Financial institutions and lenders often evaluate loan affordability using standardized mortgage formulas similar to those used in this calculator.

It compares:
- Your current loan payment
- Your new refinance payment

The calculation is based on:

It then shows a clear financial comparison to help you decide if refinancing is beneficial.

- Daily expenses
