Buying ‘extra’ paint is expensive twice — once to buy, once to dispose
Sq ft / can is the label number — varies 250–400 sq ft. Read your specific can; the formula falls apart on assumed coverage.
Coats column flags primer + 2 finish coats vs the optimistic ‘one coat’ marketing — most rebates require the actual coat count.
Pair with Room Measurement Worksheet — Area column there is the input here. Different from a budget sheet: this is the conversion, not the tally.
