Saved startup cashflow arithmetic
Read the explanation
Saved retail price sixty divided by unit cost fifteen gives four times markup. Bars compare price and cost at ten pixels per modeled dollar. Source four-times rule is a heuristic, not a guarantee of profit or viable business. Sixty less fifteen gives forty-five per unit before overhead. Twenty-five monthly sales times forty-five gives eleven hundred twenty-five gross contribution. Bars compare price and unit contribution at ten pixels per dollar; source calls this gross inflow although it already subtracts product cost. Modeled full-velocity contribution eleven hundred twenty-five less monthly burn four hundred fifty gives six hundred seventy-five net cashflow. Bars share zero at point four pixels per monthly dollar. Early months ramp sales linearly to month four, while displayed runway divides reserve by burn without sales. Raw native blueprint/reset/resize preserved; actual profitability unproved.
