The decision
A seller charges ₹900 and sells 1,000 monthly units with ₹540 variable cost. A ₹990 option is projected to sell 850 units. Monthly fixed cost is ₹2.5 lakh.
Which price is more profitable, and where does the choice reverse?
Worked solution
Reveal the visual and solution
- Base profit is (₹900 − ₹540) × 1,000 − ₹2.5 lakh = ₹1.1 lakh. New profit is ₹450 × 850 − ₹2.5 lakh = ₹1.325 lakh.
- At the new margin, 800 units match baseline contribution. The observed forecast implies base-period elasticity of −15% ÷ 10% = −1.5.
- Pilot the new price and compare retained volume and refunds. Revert if sustained unit volume falls below 800 and no other economics change.
