The Truth in Lending Act (TILA), enforced by the CFPB via Regulation Z, requires lenders to disclose your loan's key costs in a standard box before you sign. The four figures that matter most: APR (the yearly cost as a rate), Finance Charge (total dollar cost of credit), Amount Financed, and Total of Payments. Always compare loans by APR, not the monthly payment — a lower payment can hide a longer term and far more interest.
The TILA disclosure box
| Disclosure | What it tells you |
|---|---|
| APR | Yearly cost of the loan as a percentage — the key comparison number |
| Finance charge | Total dollars the credit will cost you |
| Amount financed | The credit provided (price minus down payment/trade, plus financed items) |
| Total of payments | Amount financed + finance charge over the full term |
| Payment schedule | Number, amount and timing of payments |
What TILA is and why it exists
The Truth in Lending Act standardizes how lenders disclose credit costs so borrowers can compare offers on equal footing. For auto loans it means the dealer or lender must give you a clear disclosure of the APR and dollar costs before you commit, implemented through the CFPB's Regulation Z.
The four numbers to read first
- APR: the annualized cost including interest and certain fees — the single best figure for comparing loans.
- Finance charge: the total dollar cost of borrowing over the life of the loan.
- Amount financed: how much credit you're actually receiving.
- Total of payments: what you'll have paid by the end — amount financed plus the finance charge.
APR vs interest rate vs monthly payment
The interest rate is the base cost of the money; the APR folds in certain fees, so it's usually slightly higher and more comparable across offers. The monthly payment is the least reliable comparison — a dealer can lower it simply by extending the term, which increases total interest. Judge deals on APR and total of payments.
Watch the amount financed
The amount financed grows when add-ons — extended warranties, GAP, service plans, dealer fees — are rolled into the loan, and you then pay interest on all of it. Check that everything in the amount financed is something you actually chose and want to finance at the loan's APR.
How to use the disclosure
- Get the TILA disclosure in writing before signing anything.
- Compare APR and total of payments across at least two or three offers.
- Question any add-ons inflating the amount financed.
- Confirm the term, number of payments and any final/balloon payment.
- Check for prepayment penalties; prefer a simple-interest loan you can pay down early.
