Campaign Cost Calculator

One-time costs like books and miniatures are purchased once regardless of how long the campaign runs, so they represent a fixed upfront investment, while recurring costs like subscriptions and snacks accumulate the longer and more often you play. Separating them shows how much of your total spend is a fixed startup cost versus an ongoing commitment tied to session frequency.

Total cost keeps climbing the longer a campaign runs, since recurring costs accumulate with every additional month and session, but cost per session tends to fall over a long campaign because the one-time upfront costs get spread across more and more sessions. A short campaign carries a higher effective cost per session simply because there are fewer sessions to absorb the initial book and miniature purchases.

Four hours is a commonly cited typical session length for tabletop RPG groups, used here as a standard conversion factor to translate total cost into an hourly entertainment cost that's easy to compare against other activities like movies or streaming subscriptions. If your group's sessions run notably longer or shorter, the actual cost per hour of play will differ from this estimate.

This calculator reports the group's combined total spend rather than assuming any particular split, so how costs get divided is a separate decision — some groups have the GM cover shared resources like terrain and books while players bring their own dice and snacks, while others split everything evenly. Dividing the cost-per-session figure by the number of regular players is a straightforward way to work out an even split.

Since recurring costs — subscriptions and snacks — accumulate every month and session regardless of the one-time purchases already made, trimming those two line items has the biggest impact on a long campaign's total cost. Sharing a single digital subscription across the group instead of individual accounts, or rotating snack duty among players, are common ways groups reduce the recurring side of the budget.
