Is gross profit comparable to contribution margin?

Its different. Gross profit (Sales Revenue - Cost of Goods Sold); It is the amount available to cover the company's operating expenses. Contribution Margin (Sales Revenue - variable costs); it is the amount available to cover fixed costs.

SALES REVENUE - ( DIRECT MATERIAL+ DIRECT LABOR + VARIABLE FACTORY OVERHEADS) = CONTRIBUTION MARGIN,        I.E  MARGIN  TO MEET THE FIXED EXPENSES

Gross profit (GP) is different from Contribution margin (CM).

GP is the difference between Sales and Cost of Sales under Absorption costing/full costing while CM is the difference between Sales and Variable manufacturing costs under  Variable costing. The difference results from different treatment of fixed manufacturing cost under both costing method.

No.

NO The basic difference B/W

G.P = SALES -CGS

CM= REVENUE - V .MANUFACTURING COST

TREATMENT IS DIFFERENT

No....

Both are difference in every sense 

If you compare both and make a decision on the basis of it, it will lead to trouble 

No Sir GP and CM are totally different.

contribution margin = sales minus variable cost 

gross margin = sales - COGS ( both fixed and ( variable )
