Home Credit Card Monthly Interest Calculator (5 Years)

Estimate monthly interest on a card balance. This home version uses a 5-year planning term as its starting point.

The result, labelled Monthly interest, is the interest charged on the balance in a single month at the entered annual rate, so paying only this amount leaves the balance unchanged, while paying more than this amount reduces the balance.

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 percent, term 5 years. Using the page formula, monthly interest equals $5,000 times 18 divided by 100 divided by 12, which is $75.00 per month. That is the calculator's own result for these defaults, and it is the same on every page in this group because the term is not an input.

As an illustration only, if only the $75 interest is paid every month and the balance never falls, then over 5 years the interest paid totals $75 times 12 times 5, which is $4,500. At the end of that term the balance would still be $5,000, because paying only interest leaves the balance unchanged. That total is an illustration, not the output of this page: it assumes the balance stays at $5,000 and the rate stays at 18 percent for the whole term, which will not happen if new home spending is added to the card or the rate changes.

Who this term suits for a home household: a home household that had to put an urgent home cost on a card, such as a broken boiler, a leaking roof repair, or a replacement fridge, and has a firm plan to clear the balance well inside 5 years. Five years is already a long time to carry card debt, so this term only makes sense if every month pays well more than the $75 interest.

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 home 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.

If I pay only $75 a month for 5 years, is the card cleared?
No. Paying only the interest for 5 years costs $4,500 in interest and leaves the full $5,000 balance still owed, because paying only interest leaves the balance unchanged.

What home purchase makes a 5-year card plan worth it?
Only an urgent, planned home cost with a firm payoff plan, such as an emergency repair that could not wait. A 5-year card plan only works if the household pays well more than $75 every month, so the balance itself falls.

How much above $75 a month starts to clear $5,000 in 5 years?
As a simple illustration, $5,000 divided by 60 months is $83.33 of principal a month, on top of the interest due that month. In practice the interest falls as the balance falls, so the exact payoff payment depends on the card's own terms.
