Why This Matters
A payoff date can look precise while hiding the minimum-payment rule or assuming extra cash that is not consistently available. Keeping those inputs visible makes it easier to understand what a change in payment actually changes.
How It Works
For each debt, record the balance, APR, minimum, due date, and any fees. Apply the minimum to every account, then model the extra amount under one stated allocation method. Recalculate after each payment or new charge. CFPB materials explain that interest may accrue daily and that paying more than the minimum can shorten the payoff period.
Example
Illustrative example: a $2,400 balance at 24% APR with a $75 minimum and $125 of extra monthly cash has a total planned payment of $200. The exact payoff date depends on the issuer’s minimum formula, daily interest, fees, and whether new purchases are added, so the example is a method demonstration rather than a promised result.
Start With the Required Payments
Minimum payments are not a detail to add after a payoff strategy is chosen. They are the baseline obligation for each account. A timeline that assigns all available extra cash to one balance but does not reserve the required minimums for the other balances is not modeling the account terms that exist.
Make one row for each debt. Include the balance, APR, required minimum, due date, and any known fee or promotional condition. Then add the total of all minimums before deciding what, if any, extra amount belongs in the illustration. That sequence prevents a payoff date from relying on money that was already needed elsewhere.
What the Extra Payment Actually Changes
In the example, $75 is the required minimum and $125 is the additional amount. Together they make a $200 planned payment. If the additional amount falls to $50 in a later month, the timeline changes; it is not a failure of the plan. It is a new input.
Interest timing matters too. The CFPB explains that many card issuers calculate interest daily, and account terms can affect how payments are applied across balances. That is why a clean spreadsheet estimate should not be presented as the same thing as an issuer's payoff quote or statement balance.
Choose a Method, Then Keep the Assumptions Visible
People often compare different payment-order methods, such as sending extra cash toward the smallest balance or the highest APR. The article does not prescribe one. A useful comparison identifies the method, keeps every minimum payment in place, and shows the same extra-cash amount across each scenario.
Once the method changes, the result changes. Once a new purchase, fee, missed payment, rate change, or income shift changes the inputs, the result changes again. A payoff timeline is valuable because it makes those changes visible, not because it can guarantee a calendar date.
Basis Angle
Basis can keep minimum obligations, extra cash, and goal funding in the Financial Plans section. It can show how a changed payment affects projected progress, and in the Decision Lab you can model payoff outcomes based on what contribution amounts you choose for each debt.
Key takeaways
- CFPB explains that the minimum payment is required by the due date and that paying more can reduce interest and payoff time.
- APR and daily interest mechanics affect how quickly a balance falls.
- A timeline is a projection, not a promise; new charges and missed payments change it.
Frequently asked questions
Why include minimum payments if I plan to pay extra?
Minimums are the required baseline that keeps each account current. The extra amount is the variable that changes the projected timeline.
Does APR alone determine the payoff date?
No. Balance, minimum-payment formula, payment timing, fees, and new charges also affect the result. APR is one input in the model.
Can Basis choose a debt payoff strategy for me?
No. Basis can compare user-entered scenarios and projected tradeoffs. It does not provide a personalized debt recommendation.
