Enter the number of pages of paper used and the rate of recycling into the calculator to determine the number of trees saved. This calculator can also evaluate any of the variables given the others are known.

Paper To Tree Formula

The following formula is used to calculate the number of trees saved by using recycled paper.

T = (P * R) / S

Variables:

  • T is the number of trees saved
  • P is the number of pages of paper used
  • R is the rate of recycling (decimal)
  • S is the number of pages a single tree can produce

To calculate the number of trees saved, multiply the number of pages of paper used by the rate of recycling. Then divide the result by the number of pages a single tree can produce.

How to Calculate Paper To Tree?

The following steps outline how to calculate the number of trees saved using the Paper To Tree formula.


  1. First, determine the number of pages of paper used (P).
  2. Next, determine the rate of recycling (R) as a decimal.
  3. Next, determine the number of pages a single tree can produce (S).
  4. Next, gather the formula from above = T = (P * R) / S.
  5. Finally, calculate the number of trees saved (T).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

number of pages of paper used (P) = 250

rate of recycling (R) = 0.75

number of pages a single tree can produce (S) = 5000
