How to Use This Calculator
  1. Enter the number of experiments per week and average pages per experiment.
  2. Set the notebook size in pages to determine how long it will last.
  3. Input the number of researchers sharing notebooks if applicable.
  4. Review the projected notebook lifespan in weeks and annual notebook consumption.
  5. Use the estimate to purchase an adequate supply of lab notebooks for the year.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Experiments per week = 5, Pages per experiment = 3, Number of researchers = 4, Pages per notebook = 200 = 6 input(s) provided
  2. Calculate Notebooks per year
    Notebooks per year = notebooksPerResearcherPerYear * numResearchers
    14.4 = 14.4
  3. Calculate Annual notebook cost
    Annual notebook cost = totalNotebooksPerYear * notebookCost
    360 = $360
  4. Calculate Pages/week/researcher
    Pages/week/researcher = experimentsPerWeek * pagesPerExperiment
    15 = 15
