Use this calculator to find the price for any number of pages. Do one book at a time, or many.
Calculate Paper Price - Use as "d" in the formula below.
Cost of the paper you bought ÷ number of sheets you bought = Price per sheet
Calculate Toner Price - Use as " f " in the formula below.
(Toner/drum replacements should say how many pages they print. A page means one side of a page filled with text at 5% coverage. A toner coverage meter shows an average of 10% coverage for RC and wordprocessor books, so we multiply toner cost by 2 in this formula.)
Cost of toner cartridge ÷ number of pages it will print × 2
+Cost of drum unit (if separate) ÷ number of pages it will print
Total toner price per page (1 side).
a = # of pages in book
b = # of pages per sheet you will print
Full size = 2 (because you print one on each side, and there are two sides)
Half size = 4 (because you print two on each side, and there are two sides)
c = # of sheets of paper you will use for this book [a ÷ b = c]
d = cost per sheet of paper [figured above]
e = total price of paper for this book [c × d = e]
f = cost of toner per (1 side of) page [figured above]
g = total price of toner for this book [2 × c × f = g]
h = total price to print this book [e + g = h]
P = # of pages to print
Q = price to print 1 page (same as "h" above, when calculated for 1 page)
R = total price to print this book [p × q]
