Mortgage Refinancing Formula Explained
The calculator uses a standard loan payment formula to determine your monthly payments:
Monthly Payment =
P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
Where:
- P = Loan amount
- r = Monthly interest rate
- n = Total number of payments
This formula ensures accurate projections for both current and new loan scenarios.
Practical Example
Let’s say you currently have:
- Loan balance: $200,000
- Interest rate: 6.5%
- Remaining term: 20 years
You are considering refinancing to:
- New interest rate: 5.0%
- New term: 20 years
- Closing costs: $4,000
Results:
- Current monthly payment: ~$1,491
- New monthly payment: ~$1,320
- Monthly savings: ~$171
- Break-even point: ~23 months
This means after about 2 years, your savings will start exceeding the refinancing costs.
When Should You Refinance?
Refinancing is beneficial in several situations:
1. Lower Interest Rates
If market rates have dropped significantly, refinancing can reduce your monthly payment.
2. Improve Cash Flow
Lower payments free up money for other expenses or investments.
3. Shorten Loan Term
Switching from a 30-year to a 15-year loan helps you pay off your home faster.
4. Switch Loan Type
You may move from an adjustable-rate mortgage (ARM) to a fixed-rate loan for stability.
