You have $25 worth of X but spent $20.
So you've now received 125% of what you payed for.
We can now drop the 1 as insignificant, leaving us with 25% remaining! I'm not sure where *your* math went wrong

That's not how you calculate discounts.
You spent $20 for $25 worth of items.
Discount:
($25 - $20) / $25 = 20%
Alternately:
(125% - 100%) / 125% = 20%
You did get 25% "cash back" though.
