Fixed vs variable cost split API

Total cost = fixedCosts + variableCostPerUnit x units, decomposed into fixed/variable ratios and cost per unit — the cost-structure breakdown behind CVP analysis. Answers 'what's my total cost at this volume', 'what's my cost per unit', 'how much of my cost is fixed vs variable'.
