Either the dealer offers to refinance the same by charging some commission or borrower wishes to lower his periodical installment or as discussed credit score has improved.

Auto Refinance Calculator Example
Mr. Jain had purchased a luxury bike around 3 years ago for $45,000. The loan financed for 90% and the rate of interest that was applicable initially was 9.00% and he had taken the loan for 5 years. His monthly installment was $840.71, and he repaid his installments without making any default and on a timely basis.

Mr. Jain has repaid installments until the end of 3 years and hence the outstanding balance shall be:
The new monthly rate of interest will be 7.50%/12 which is 0.63% and the outstanding principal balance is 18,402.50 with a loan tenure of 2 years remaining which is 24 months.
At end of 3 years
= [$18,402.50 x 0.63% x (1 + 0.63%)^24 ] / [ (1 + 0.63%)^24 – 1 ]
= $828.10
Monthly Savings
- Savings monthly = Existing EMI – New EMI
- = $840.71 – $828.10
- = $12.61 per month
Total Savings During Rest of Tenure
- Total savings during rest of tenure = savings per month x remaining loan tenure in months
- = $12.61 x 24
- = $302.60
