X Percentage Value
How this coupon works
Here
Percentage Value (D) is the fixed percentage discount
Maximum Discount Amount (MD) (optional) is a maximum limit to the discount
Minimum Cart Value (MCV) (optional) is the minimum price of the cart items
Example
A 30% discount on a shirt worth Rs. 1000
Formula
Coupon Discount = Min(MD, (CV*D/100))
Where
CV = Cart value D = Percent Discount MD = Maximum discount limit
In this example
CV = 1000 D = 30% MD = 400
Therefore
Min(400, (1000* 30/ 100)) = 300
Cart value
1000
