Test uptime, costs, revenue deductions and ±20% sale-price scenarios.

Formula and assumptions
Assumes constant saleable-liquid rate on operating days and constant price/costs. Fixed costs accrue every calendar day, including downtime. The deduction is a user-selected share of gross revenue, not a jurisdictional tax rule. Include water handling in your costs if relevant. Capital, financing, tax, decline and closure liabilities are excluded; this is an operating scenario, not an investment valuation. Zero output or 100% deduction makes break-even undefined.
V = rate × days × uptime / 100; R = V × price × (1 − royalty / 100); C = V × variableCost + fixedCost × days; margin = R − C; breakEven = C / (V × (1 − royalty / 100))Method references
