TILA requires lenders to disclose the APR, finance charge, and payment schedule before you sign. Replay one $28,000 auto loan — and three missed-deadline endings.
The Truth in Lending Act is the 1968 federal law, carried out through Regulation Z, that requires lenders to disclose the true cost of credit before a consumer is bound: the annual percentage rate, the total finance charge in dollars, the amount financed, and the full payment schedule. Missing or mis-timing those disclosures opens a lender to damages on any consumer loan — and on refinances and home-equity loans it can stretch the borrower's three-day right to cancel all the way to three years under 15 U.S.C. § 1635: the right extends up to three years when the notice and material disclosures are missing (§ 1635(a)) and cannot be extended past that outer limit (§ 1635(f)).

One model $28,000 auto loan, timestamped from application to payoff, shows where every Truth in Lending Act disclosure lands — then the file rewinds to three missed-deadline endings, each with different consequences.
This resource helps readers connect what is the Truth in Lending Act to classroom practice, standards-aware implementation, and responsible next steps for schools and sponsors.
The Truth in Lending Act (TILA) is a 1968 federal law — Title I of the Consumer Credit Protection Act — that requires lenders to tell consumers the true cost of credit before the deal binds them. Through its implementing regulation, Regulation Z, it mandates a standardized set of disclosures for most consumer loans: the annual percentage rate (APR), the total finance charge in dollars, the amount financed, the payment schedule, and the total of all payments.
Congress's goal was not to cap prices but to make them comparable — the statute describes its purpose as meaningful disclosure of credit terms so shoppers can compare costs and avoid being surprised by them. This report replays one model $28,000 auto loan from application to payoff, showing where every required disclosure lands, then rewinds the same file to three missed-deadline endings. Every dollar figure here is illustrative model arithmetic, not a real transaction.
In the compliant timeline, the model file is quiet early: the borrower applies Monday, receives a conditional quote Tuesday, and gets the full disclosure box Thursday afternoon — APR 7.4%, amount financed $28,000, sixty monthly payments of about $559.73, total of payments about $33,584, finance charge about $5,584 — every number delivered before the borrower signs. That ordering is the legal requirement itself: for closed-end loans like auto financing, disclosures must come before consummation, not after.
The replayed timeline breaks one clock at a time, and each broken clock produces a different failure. An auto lender that hands over the disclosure box after signing faces civil liability under 15 U.S.C. § 1640 — actual damages, inflation-adjusted statutory damages, and attorney's fees on a successful claim. A mortgage lender that delivers the Closing Disclosure late — Tuesday 10:00 a.m. for a planned Thursday closing — must slide consummation to Friday, until the disclosure has been in the borrower's hands for three business days. A lender that never delivers the notice of right to rescind on a refinance can leave the borrower's cancellation window open for up to three years under 15 U.S.C. § 1635(f). One file, rewound: each run breaks a single clock, and each break flips the file to a different state.
TILA became law in 1968 as Title I of the Consumer Credit Protection Act, enacted after Congress found that credit costs were disclosed unevenly — if at all — making meaningful comparison shopping nearly impossible. The Federal Reserve initially carried the law out through Regulation Z; since the Dodd-Frank Act of 2010, the Consumer Financial Protection Bureau has held primary authority to write, update, and interpret it, and it supervises many lenders for compliance.
The law reaches most consumer credit, closed-end and open-end, including dealer-arranged auto financing where the dealer plans to assign the contract to a lender. It is a disclosure statute, not a price cap: TILA never tells a lender what interest to charge, only what must be said about the charge. It pairs naturally with the Equal Credit Opportunity Act, which governs fairness in who receives credit — one law governs what borrowers are told, the other governs how they are treated.
The model file funds a $28,000 auto purchase at a 7.4% note rate over 60 months with no down payment. Rounded illustrative arithmetic puts the monthly payment at $559.73, the total of payments at $33,584, and the finance charge at $5,584; a real disclosure box would show the lender's own exact figures, computed under Regulation Z's Appendix J actuarial method. Notice what is missing from this timeline: a waiting period. Unlike mortgages, auto loans carry no federal three-day cool-off before funding.
That asymmetry is the first teaching point of the replay. The federal protection an auto buyer gets is not a delay after signing — it is the ordering before it. Nothing the borrower signs may precede the disclosure box, because consummation cannot lawfully outrun the numbers.
Regulation Z's § 1026.18 checklist defines what a closed-end disclosure must contain, and § 1026.17 sets its timing: before consummation. The box is standardized on purpose, so a shopper can place two lenders' offers side by side and compare them line by line. For the model file, the box reads:
On the clean file, the two numbers match: a 7.4% note rate and a 7.4% APR, because the only finance charge is interest itself. Now the replay introduces one fee — a $500 documentation charge financed into the same $28,000 note. The note rate stays 7.4% and the payment stays about $559.73, but Regulation Z subtracts the prepaid fee from the amount financed, which falls to $27,500, while the total finance charge grows to about $6,084 and the APR climbs to about 8.1–8.2%. Those are rounded model figures — but the mechanism is exactly what the APR disclosure exists to reveal.
The rate prices the money; the APR prices the deal. That is why Regulation Z's Appendix J prescribes the precise actuarial computation: the number a lender may not massage is the number Congress placed at the top of the box.
TILA runs on clocks, and they differ by product. Auto loans: disclosures before consummation, no rescission right. Most mortgage applications: a Loan Estimate within three business days of application and a Closing Disclosure at least three business days before consummation under Regulation Z § 1026.19. Rescindable loans — refinances and home-equity lines secured by a borrower's principal dwelling: a three-business-day cancellation window that opens at midnight after consummation, delivery of the notice, or delivery of all material disclosures, whichever comes last.
The Disclosure Clock Replay rewinds the file to the same Thursday afternoon and breaks one clock per run, and the file's status changes state with each failure — from clean, to curable, to delayed, to liable, to cancelable for years. That rewind-and-state-change mechanic is what separates this replay from the rest of the cluster: one clock, one flip, no branching storyline. The three tracks walk the endings below, and in the Run the Replay Yourself console that follows, the badges flip on screen exactly as they do here.
The Disclosure Clock Replay Console runs the same file you just read on the same replay week. Three tracks — auto, mortgage, refinance — each carry one breakable clock, and each run breaks exactly one: the badge flips once, and the flip is the lesson. The auto track moves clean → curable → liable as the § 1640(b) cure window opens and closes; the mortgage track moves clean → delayed — a delay state, not a cure window — when the Closing Disclosure lands inside its three-business-day window; the refinance track moves clean → cancelable-for-years when the rescission notice never arrives. Every badge carries the timestamp that triggered it.
This rewind-and-state-change mechanic is the differentiator: the file always returns to the same Thursday afternoon, one clock breaks per run, and no branching storyline dilutes the result — timing, not terms, decides which state the file ends in.
For bank training teams, the file works as onboarding practice: new lending staff trace which clock governs which product — disclosure-before-consummation for auto credit, the Loan Estimate and Closing Disclosure rhythm for mortgages, the rescission window for refinances and equity lines — and practice rewriting a failed timeline into a compliant one. In the Run the Replay Yourself console, trainees can break one clock per track first, watch the badge land on curable, delayed, liable, or cancelable-for-years, then rewrite the timeline back to clean. Paired with the ECOA Scenario Checker, the same staff cover both rails of lending law in one sitting: what borrowers are told, and how they are treated.
For classrooms, the disclosure box is a reading exercise with stakes: students learn to separate APR from interest rate, finance charge from amount financed, and total of payments from total sale price — consumer-credit skills the National Standards for Personal Financial Education place in the credit strand. The replay format turns memorized vocabulary into a timeline students can narrate from memory, and the console lets them do the rewinding themselves: one clock broken per run, one badge flipped per failure.
Where the model stops: this file contains no real borrower, lender, or transaction, and every dollar figure is rounded illustrative arithmetic. Rules vary by product type, lender type, and state overlay, and dollar figures change over time, so institutions should verify current requirements in Regulation Z and consult qualified counsel; this page is educational, not legal or compliance advice. The public sources behind every legal claim — the statute, Regulation Z, and the rescission and liability provisions — appear in the source list below.
No. The federal right of rescission applies only to certain loans secured by a borrower's principal dwelling — typically refinances and home-equity lines — not to auto purchases. An auto buyer's federal protection is the pre-signing disclosure: Regulation Z requires all key closed-end disclosures before the borrower is contractually bound, with no post-signing cancellation window attached.
The interest rate prices the borrowed principal; the APR prices the whole deal, folding the interest rate plus most required fees into one standardized yearly figure computed under Regulation Z's Appendix J. Two lenders quoting the same rate can have different APRs once fees differ — which is why TILA puts the APR in the disclosure box in the first place.
Before consummation — the moment the borrower becomes contractually obligated on the deal. Unlike mortgages, auto loans carry no federal requirement to disclose at the application stage and no three-day waiting period before funding; the entire obligation is that the standardized numbers reach the borrower before signing.
The lender faces civil liability under 15 U.S.C. § 1640: actual damages, statutory damages the statute set between $100 and $1,000 per violation (adjusted upward over time by CFPB inflation adjustments), and attorney's fees on a successful claim. On rescindable mortgage loans, missing material disclosures or the rescission notice can extend the borrower's cancellation window: under 15 U.S.C. § 1635 the right of rescission extends up to three years (§ 1635(a)) and cannot be extended past that outer limit (§ 1635(f)). If the error was unintentional and resulted from a bona fide error despite procedures reasonably adapted to avoid it, a creditor that notifies the borrower within 15 days of discovering it and makes appropriate adjustments to the account can limit liability under § 1640(b).
The Loan Estimate is the standardized three-page form most mortgage lenders must send within three business days of receiving a completed application, under the TILA-RESPA Integrated Disclosure rules in Regulation Z. Auto loans and other closed-end consumer loans do not use the Loan Estimate; they rely on the closed-end disclosure box with the same core numbers — APR, finance charge, amount financed, and payment schedule — delivered before signing.
Yes. TILA has been in force since 1968 and is implemented through Regulation Z, 12 CFR Part 1026. Since the Dodd-Frank Act of 2010, the Consumer Financial Protection Bureau has had primary authority to write and update the regulation, while other federal regulators supervise the institutions within their jurisdictions and state attorneys general can bring certain enforcement actions.
No. TILA is a disclosure statute, not a usury law: it requires lenders to state the cost of credit clearly and comparably, but it does not limit what that cost may be. Rate caps come from separate state and federal laws that govern specific products.
