Interest-Free Period
Also known as: Grace period, Interest-free days
In simple terms
An interest-free period is the time you get to pay off credit card purchases before any interest is charged. Clear your balance in full within it and those purchases cost you nothing extra.

What does interest-free period mean?
An interest-free period is the gap between making a purchase on a credit card and the date the payment is due, during which no interest is charged — provided you pay the balance in full. On many cards this can be up to around 56 days.
It applies to purchases when you clear the statement each month. It does not usually apply to cash advances, and it can be lost if you carry a balance forward.
How an interest-free period works
The interest-free window runs from the start of your statement cycle to the payment due date. Buy something early in the cycle and you get the longest interest-free stretch; buy just before the statement date and you get much less.
The catch: the interest-free benefit generally only applies if you pay the statement balance in full every month. Carry a balance over and interest can be charged on new purchases straight away, wiping out the interest-free period until you clear it again.
How could this affect me?
Used well, the interest-free period lets you use a credit card for everyday spending and pay nothing in interest, while keeping useful protections like Section 75. It effectively gives you a short, free loan each month.
Used badly — by paying only the minimum or carrying a balance — you lose the interest-free benefit and start paying interest on purchases. The single most valuable habit is clearing the statement balance in full each month.
Things to watch out for
- The interest-free benefit usually only applies if you pay the balance in full each month.
- Carry a balance forward and new purchases can be charged interest immediately.
- Cash advances do not normally get an interest-free period.
- The length of the free period depends on when in the cycle you buy.
