This calculator provides estimates only. Actual savings may vary based on specific loan terms and conditions.
Key Terms to Know
- Original Loan Amount: The total amount you originally borrowed.
- Original Interest Rate: The annual percentage rate (APR) of your current loan.
- Original Loan Term: The length of your current loan in months.
- Refinance Amount: The amount you're refinancing (usually the same as original loan amount).
- Refinance Interest Rate: The new APR you're proposing to refinance at.
- Refinance Term: The new loan term in months.
Formula Used
The calculator uses the standard loan payment formula to calculate monthly payments and total interest paid:
Monthly Payment = P * (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (Annual Rate / 12)
- n = Number of payments (Loan Term in Months)
The total interest paid is calculated by subtracting the original loan amount from the total amount paid over the life of the loan.
Worked Example
Let's say you have a $20,000 auto loan with a 5% APR and a 60-month term. You're considering refinancing to a 3.5% APR with a 72-month term.
| Term | Original Loan | Refinanced Loan |
|---|---|---|
| Loan Amount | $20,000 | $20,000 |
| Interest Rate | 5% | 3.5% |
| Loan Term | 60 months | 72 months |
| Monthly Payment | $376.49 | $303.17 |
| Total Interest Paid | $1,127.84 | $1,534.48 |
| Total Amount Paid | $21,127.84 | $21,534.48 |
In this example, you would save $127.84 in total interest by refinancing, but your monthly payment would decrease by $73.32. The longer term means you'll pay more in total but less per month.
