Contracts are written in vocabulary most people don’t use twice a year — and payday agreements use more of it per square inch than most. Here are the 24 terms that actually change decisions, each in plain English. No term on this list is legal advice; each is the definition a borrower needs before signing one.
The Money Terms
APR (Annual Percentage Rate). The cost of credit expressed as a yearly rate, including interest and mandatory fees. A $15-per-$100 two-week fee annualizes to ~391% — the APR doesn’t change what you owe; it lets you compare loans of different lengths.
Finance charge. The total dollar cost of the loan: interest plus mandatory fees. This is the number that leaves your wallet. See it worked per state in the cost table.
Principal. The amount you actually received. Fees are charged on it, and every rollover keeps it whole while adding charges.
Total of payments. Principal plus all finance charges — what you’ll have paid when the contract ends. Federal law requires it on the disclosure.
NSF fee. “Non-sufficient funds” — the charge when the repayment debit bounces. Your bank may charge one too. State caps control the lender’s version.
The Mechanics
ACH authorization. Your written permission for the lender to pull the repayment electronically from your checking account. The standard repayment mechanism for online advances.
Post-dated check. The storefront-era equivalent: a check dated for payday, held by the lender. A repayment instrument, not collateral — secured vs unsecured explains why.
Rollover / extension. Paying a fee to push the due date back. The fee recharges on the untouched balance — the mechanics of the debt cycle. Banned outright in some states, capped in others.
EPP (Extended Payment Plan). A no-extra-fee repayment schedule some states force lenders to offer after repeated rollovers. Free money if you’re eligible — ask for it by name.
Balloon payment. One lump sum covering everything at the end — the payday model itself. The alternative is amortized installments.
Rescission right. A state-law window to cancel the loan at no cost, typically one to three business days. Listed on every state page here.
The Credit-Check Terms
Soft check (soft inquiry). A verification that doesn’t affect your credit score. The request stage of every network on this site.
Hard check (hard inquiry). A full bureau pull that can ding your score a few points. Some lenders run it before final approval — they must disclose which.
Alternative underwriting. Approval based on bank transaction data and income regularity instead of FICO — how bad-credit borrowers get approved at all.
Credit bureau. Equifax, Experian, TransUnion. Most payday lenders don’t report on-time payments to them; collections usually do (details).
The Industry Terms
Direct lender. The company that actually makes the loan and funds it. The one whose name should be on your agreement.
Lead aggregator / referral service. A company (like this site) that forwards your request to lenders. Honest ones say “we are not a lender” plainly and never charge applicants.
Pingtree. The routing system that sends one request to multiple lenders in sequence or parallel — why one form produces several offers.
CSO / CAB (Credit Access Business). Texas’s broker model: a licensed intermediary that arranges the loan and charges its own fee on top of the lender’s. See the Texas page.
Tribal lender. A lending company chartered by a federally recognized tribe, operating under sovereign authority rather than state license — legal, federally disclosed, priced above state-regulated credit (full explainer).
The Legal Terms
State cap. The legal ceiling on loan amount, fee, or both — the single biggest driver of what a loan costs (your state).
Statute of limitations. The deadline after which a creditor generally can’t win a lawsuit over a debt — separate from the debt itself and from credit reporting (how the clocks work).
Secured / unsecured. Whether property backs the loan. Payday advances are unsecured; title loans are secured by your car.
Underwriting. The lender’s review of whether you can repay — income, account history, identity. The step scams skip.
