I want to share discount formula with you.
I used to eyeballing prices, like if 1 item costs $40, I can give 2 for $70.
Later, I started using an automated formula that gives bulk discounts:
discounted price = unit price * n^f
Where n is the total number of units purchased and f is a scaling factor between 0 and 1.
So, for example, if my unit price is $24.95 and f is 0.8, the discounted price for 10 units is $24.95 * 100.8 = $157.42, which you can then round to a more aesthetically appealing number.
I'm interested to see if there is a better formula out there.
What formula do you use?
