Approval ≠ payout
00:33 · EP01-C01Authorization is the issuer’s approval response; a merchant payout need not have arrived when approval appears.
Visa Developer ↗Acquirer / network / issuer
00:39 · EP01-C02A Visa-style purchase involves the merchant/acquirer, network and issuing bank. The cardholder repays the issuer.
Visa merchant explanation (Canada; structural roles only) ↗Authorization → clearing → settlement
01:08 · EP01-C03For the illustrated process, submission/capture enables clearing and settlement after authorization. Other payment configurations can differ.
Visa Developer ↗No single payout deadline
01:23 · EP01-C04Merchant access to funds depends on the payout arrangement. Square offers differing transfer/access options; this is not a universal timing promise.
Square Transfers ↗Pending / posted
01:35 · EP01-C05A pending authorization can hold available credit; the final amount may change, including for a tip. Pending status is not proof of merchant funds availability.
Capital One Help Center ↗2.6% + $0.15
02:09 · EP01-C06The example uses Square Free, U.S. tap/dip/swipe pricing for a domestic-issued card, with no additional fees. Rechecked November 1, 2026. Other plans and payment types differ.
Square Support ↗$2.75 fee / $97.25 remainder
02:19 · EP01-C07Our arithmetic on that $100 example gives $2.60 plus $0.15 in fees and $97.25 left for the merchant before other costs. Penny still owes the modeled $100 purchase.
Cash Splained calculation from Square pricing ↗Exact split not established
02:44 · EP01-C08Interchange is one component of merchant pricing and generally flows from acquirer to issuer. Published Square pricing does not establish its private issuer/network/provider split.
Mastercard ↗Statement snapshot
03:11 · EP01-C09Statement balance is the amount at billing-cycle close; subsequent activity can change current balance. The modeled statement has only one $100 charge and no other activity.
Capital One ↗$25 paid → $75 remains, in our example
03:33 · EP01-C10Minimum payment and full statement balance are different amounts. Paying the minimum does not itself guarantee no interest. The $25 minimum is invented for teaching, not an issuer quote.
Chase; grace conditions separately supported by CFPB ↗Eligible grace + full timely payment
03:57 · EP01-C11Purchase grace is conditional. The example assumes an eligible account on a card offering it, with full statement balance paid by the due date.
CFPB ↗No guaranteed immediate grace reset
04:29 · EP01-C12Not paying in full can remove purchase grace; new purchases may then accrue interest from purchase dates. Restoration and cash-advance treatment require the actual terms.
CFPB ↗25% hypothetical APR
04:51 · EP01-C13APR expands to annual percentage rate. The 25% shown is a made-up example, not a current average or offer.
CFPB ↗About $0.07 for one day
04:58 · EP01-C14For this separate unchanged, interest-bearing $100 balance, our 365-day calculation is 0.25 ÷ 365 × $100 = $0.068493…, rounded to seven cents for one day. Actual methods differ, including 360/365 day conventions.
Cash Splained calculation; CFPB daily-rate definition ↗Amount + date + successful payment
05:21 · EP01-C15Autopay can use minimum, statement-balance or other settings. Check scheduled amount/date and account terms. The example assumes adequate funds and a successfully processed payment; autopay does not override grace conditions.
