Total interest calculator
See what the loan costs beyond principal.
Compare APR and loan length to understand total interest and how quickly the remaining balance changes.
Decision inputs
Build the estimate.
Change any assumption. The result updates immediately.
State selection applies a base statewide sales-tax estimate; local and vehicle-specific rules can differ. Title and registration fees stay editable when no verified estimate is available. Credit-tier defaults use Q1 2025; APR remains an assumption, not a lender quote or approval decision.

BalanceCompare the lifetime cost of APR and term
Enter the same principal under multiple APR and term combinations. The monthly payment may fall when the term grows, while total interest and negative-equity exposure can rise.
Use a lender's final disclosures for a decision. Advertised APRs may require specific credit, vehicle, term, amount, membership, or automatic-payment conditions.
Decision checklist
- Compare equal principal amounts.
- Review total payments, not only the monthly amount.
- Ask whether early payoff changes fees or interest treatment.

Take the estimate into a lender comparison.
These estimates are a planning starting point.
Actual approval, APR, taxes, and fees depend on the borrower, vehicle, lender, and location. Compare a written offer using the same principal and term.
