Business Credit Card Monthly Interest Calculator (20 Years)

Estimate monthly interest on a card balance. This business version uses a 20-year planning term as its starting point.

In real terms, the Monthly interest figure is the cost of carrying the balance for one month, so a payment equal to it does not reduce the balance, and only a larger payment brings the balance down.

Formula

Monthly interest equals balance times annual rate divided by 100 divided by 12.

How it works

Paying only interest leaves the balance unchanged. Paying more than interest reduces the balance.

Worked example

Balance $5,000, annual rate 18%, term 20 years. Monthly interest is $5,000 times 18, divided by 100, divided by 12, which is $75.00 a month. That is the calculator's own output, and it is the same every month because the balance and rate do not change. If the business pays only interest, after 20 years it has paid $18,000 in interest, which is 360% of the balance, and it still owes the original $5,000. Paying more than $75.00 in any month is what finally reduces that balance.

Who this term suits for a business: a business audit or turnaround review, where a card balance that has lasted 20 years is treated as a warning sign: $18,000 of interest, 360% of the balance, for a debt that never shrank.

FAQs

Why is card interest high?
Card rates are usually higher than loan rates, so balances grow quickly if only minimum payments are made.

Is this business calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Is it ever sensible for a business to pay card interest for 20 years?
Almost never as a plan: 20 years of interest-only payments cost $18,000 on a $5,000 balance, far more than most term loans would cost for the same borrowing.

How much profit must a business make just to cover $75 a month?
At least $75 a month of profit before other costs, every month, just to stand still, because that payment does not reduce the $5,000 owed.

What should a business do first if its card balance has lasted 20 years?
Stop adding new spending to that card, pay more than interest, and compare a consolidation loan or overdraft with a qualified adviser.
