Lab Notebook Page Calculator

Notebooks per year is calculated as pages consumed divided by pages per notebook, so a notebook with more usable pages lasts each researcher longer before it needs replacing -- moving from an 81-page notebook to a 200-page notebook, for example, roughly cuts annual notebook consumption by more than half, holding experiment frequency and documentation depth fixed.

No -- notebook consumption is determined entirely by how many pages the team's experiments generate divided by pages per notebook; the price of each notebook never enters that calculation. Notebook cost only scales the resulting dollar figure -- a more expensive notebook raises annual notebook cost proportionally without changing how many notebooks are actually consumed.

Experiments per week is a direct positive multiplier on pages consumed per researcher per week (alongside pages per experiment), so running more experiments each week raises total page consumption proportionally throughout the input's range, before any other factor -- team size, notebook size, or weeks worked per year -- comes into play.

The calculator compares projected annual paper notebook cost against a mid-range ELN subscription estimate of about $200 per researcher per year, as a rough directional reference point -- not a specific vendor quote. Real ELN pricing varies substantially by vendor, feature tier (e.g., regulatory compliance modules), and contract volume, and the comparison does not account for ELN's other benefits like searchability and simultaneous multi-user access.

Total notebooks per year is calculated as notebooks-per-researcher times the number of researchers, so adding a researcher who documents experiments at the same typical pace adds their own notebook consumption on top of the team's existing total, throughout the input's declared range. A team of eight researchers consumes roughly twice the notebooks of an otherwise-identical team of four.
