Math Formulas: Profit and Loss

Cost Price:

The price, at which an article is purchased, is called its cost price, abbreviated as C.P.

Selling Price:

The price, at which an article is sold, is called its selling prices, abbreviated as S.P.

Profit or Gain:

If S.P. is greater than C.P., the seller is said to have a profit or gain.

Loss:

If S.P. is less than C.P., the seller is said to have incurred a loss.

IMPORTANT FORMULA

1. Gain = (S.P.) - (C.P.)
2. Loss = (C.P.) - (S.P.)
3. Loss or gain is always reckoned on C.P.
4. Gain Percentage: (Gain %)
        Gain % = (Gain x 100)/C.P.
5. Loss Percentage: (Loss %)
        Loss % = (Loss x 100)/C.P.
6. Selling Price: (S.P.)
        SP = ((100 + Gain %)/100) x C.P
7. Selling Price: (S.P.)
        SP = ((100 - Loss %)/100 x C.P
8. Cost Price: (C.P.)
        C.P. = ((100/(100 + Gain %) x S.P.
9. Cost Price: (C.P.)
        C.P. = ((100/(100 - Loss %) x S.P.
10. If an article is sold at a gain of say 35%, then S.P. = 135% of C.P.
11. If an article is sold at a loss of say, 35% then S.P. = 65% of C.P.
