Method
Projects next-month demand from your growth assumption, calculates runway and safety-adjusted runway, and sets reorder point to lead-time demand plus safety stock.
Assumptions and limits
Enter measured values or your own documented assumptions. This planning tool does not replace a printer, manufacturer, fulfillment partner, or shipping quote.

Plan the decision before stock reaches zero
Current stock divided by projected monthly demand gives runway. The reorder point combines lead-time demand with safety stock; it is a planning trigger, not a sales forecast.
Use the result in a design decision
If a game sells 100 units per month and a reprint lead time is six months, waiting until only 100 copies remain creates an avoidable stockout risk. Update demand after promotions, distribution changes, or a campaign.
