- Eligible spend = 1200
- Cashback rate = 5
- Fee paid to earn it = 0
- Cashback before fees = 1200*5/100 = 60
- Net cashback = max(60-0,0) = 60
- Net purchase cost = 1200-60 = 1140
- Effective reward rate = 1200>0?60/1200*100:0 = 5
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
