- Profit = S.P. − C.P. | Loss = C.P. − S.P.
- Profit % = (Profit / C.P.) × 100 | Loss % = (Loss / C.P.) × 100
- S.P. at profit p% = C.P. × (1 + p/100) | S.P. at loss l% = C.P. × (1 − l/100)
- Discount % = (Discount / M.P.) × 100, where Discount = M.P. − S.P.
- Successive discount shortcut: net discount = x + y − (xy/100)
- If CP of n articles = SP of m articles ⇒ Profit% = ((n−m)/m)×100
