APR (annual percentage rate) — APR is the yearly cost of borrowing money expressed as a percentage, including interest plus standard fees, used to compare consumer-credit products on a like-for-like basis under the Truth in Lending Act.
APR is required disclosure on consumer credit (credit cards, personal loans, auto loans, mortgages) in the US under TILA. It folds interest and certain mandatory fees into a single annualised rate.
A payday loan with a $15 fee on $100 over 14 days has an APR around 391%. The same dollar fee structured as Earned Wage Access does not require APR disclosure because there is no underlying loan.
Kronos pay advances are 0% APR — there is no interest, no late fee, no mandatory tip. The advance is structured as Earned Wage Access (EWA), so APR disclosure under TILA is not required (we still display "0% APR" prominently because users expect to see it).
On Kronos, yes — no hidden fees, no spread, no mandatory tip. The Pro subscription ($9.99/mo) is the cost of the higher cap, not of the advance itself.
