Formula Used
The calculator uses the following formulas to compare your current loan with potential refinanced terms:
Monthly Payment Calculation:
P = L × (r × (1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Monthly payment
- L = Loan amount
- r = Monthly interest rate (annual rate / 12)
- n = Number of payments (loan term in months)
Total Interest Paid:
Total Interest = (Monthly Payment × n) - L
Savings Calculation:
Savings = (Current Total Interest) - (Refinanced Total Interest)
Worked Example
Let's compare a current loan with a potential refinance scenario:
Current Loan Details
- Loan Amount: $20,000
- Current Interest Rate: 6.5% APR
- Remaining Term: 48 months
- Monthly Payment: $432.87
- Total Interest Paid: $5,191.44
Refinanced Loan Details
- Loan Amount: $20,000
- New Interest Rate: 4.5% APR
- New Loan Term: 60 months
- New Monthly Payment: $362.48
- Total Interest Paid: $3,148.80
Comparison Results
- Interest Savings: $1,942.64
- Total Savings: $1,942.64
- Time Saved: 12 months
In this example, refinancing saves $1,942.64 in interest and reduces the monthly payment by $70.49 while extending the loan term by 12 months.
