Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • A reconciled credit-card transaction register and statement check.
  • A billing-cycle timeline with current balance, statement balance and applicable payment action.
  • A balance-days interest worksheet with rate units and calculation limits.
  • A payment-allocation ledger with category balances and a total-debt check.
  • A promotional repayment calendar with a full-payoff check and offer-type comparison.
  • A next-statement audit with credited payments, new charges and an exception note.

Review and revise

Use these criteria to check your work and choose what to improve.

  • All supplied records reconcile and the decision uses the named case rules.
  • Calculations show units, intermediate values and a second check.
  • Changed-input practice revises the affected result and identifies uncertainty.
  • The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life

This is an original fictional practice case. No account, payment, personal record or outside participation is required. Balances: cash advance $300 at 30%; purchases $700 at 18%. Payment $150, minimum $40. Case issuer allocates the $40 minimum to purchases; excess goes to higher-rate debt. Ignore new interest. For the covered U.S. credit-card accounts, the general Regulation Z rule directs amounts above the required minimum to higher-APR balances first. It does not prescribe how the issuer allocates the minimum. Special provisions can apply, including deferred-interest balances near expiration and certain secured balances; verify the actual agreement and applicable rule before real use. This ordinary mixed-rate case contains no such special balance, and its minimum allocation is supplied only for this exercise.

The idea

Separate the issuer’s minimum-payment allocation from the general higher-rate-first rule for amounts above the minimum.

Allocate a mixed-rate card payment — worked practice

Separate the issuer’s minimum-payment allocation from the general higher-rate-first rule for amounts above the minimum.

Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Balances: cash advance $300 at 30%; purchases $700 at 18%. Payment $150, minimum $40. Case issuer allocates the $40 minimum to purchases; excess goes to higher-rate debt. Ignore new interest. For the covered U.S. credit-card accounts, the general Regulation Z rule directs amounts above the required minimum to higher-APR balances first. It does not prescribe how the issuer allocates the minimum. Special provisions can apply, including deferred-interest balances near expiration and certain secured balances; verify the actual agreement and applicable rule before real use. This ordinary mixed-rate case contains no such special balance, and its minimum allocation is supplied only for this exercise.

  1. 1. Step 1: Separate minimum and excess

    Separate minimum and excess.

    You should see: $40 minimum and $110 excess.

    Separate the issuer’s minimum-payment allocation from the general higher-rate-first rule for amounts above the minimum.

  2. 2. Step 2: Apply the supplied minimum allocation

    Apply the supplied minimum allocation.

    You should see: Purchases become $660.

    Keep this intermediate result so the final decision can be checked.

  3. 3. Step 3: Apply excess to the higher-rate category

    Apply excess to the higher-rate category.

    You should see: Advance becomes $190.

    Keep this intermediate result so the final decision can be checked.

  4. 4. Step 4: Reconcile remaining debt

    Reconcile remaining debt.

    You should see: 660+190=$850, equal to 1000−150.

    Keep this intermediate result so the final decision can be checked.

Now change one thing

Payment rises to $180 with the same $40 minimum allocation. Remaining advance?

Your work

What to finish

A payment-allocation ledger with category balances and a total-debt check.

Common mistake

Watch for this

Applying the higher-rate rule to the minimum without checking the issuer’s treatment.

How can I tell I understand it?

Allocate a payment between minimum and above-minimum portions under specified mixed-rate rules on a new supplied case, with a visible intermediate check and no unsupported real-world promise.
