Festive Discounts Can Lift Orders and Still Reduce Earnings

A festive promotion can increase orders while reducing the money left to cover fixed costs. The extra volume needed to offset a discount depends on contribution per unit, not on the discount percentage alone.

That is why a headline about record orders is not a complete account of a Diwali sale. The questions are how many orders became completed sales, who funded the offer and what costs changed with the volume.

The examples in this article are invented teaching cases. They are not actual retailer results, Altys database observations or forecasts for the 2026 festive season. This is business-economics education, not a security recommendation.

First identify who pays for the offer

A customer might see a lower checkout price because the merchant cut its selling price, a brand supported the promotion, a marketplace funded a coupon or a bank offered cashback. Several arrangements can be combined in one advertisement.

The customer’s saving is not automatically the retailer’s entire loss of revenue. Commercial funding, reimbursements and accounting presentation matter. Equally, a payment-provider offer should not be assumed to cost the merchant nothing without checking the agreement.

Read the net realization and funding disclosures where available. If the split is undisclosed, label it unknown rather than making a precise margin adjustment from the banner’s discount percentage.

Contribution is what remains before fixed costs

For this teaching example:

Contribution per unit = net selling price − product cost − variable fulfilment cost

Contribution is not net profit. It excludes fixed overheads, financing costs and taxes in the example. Real businesses can classify costs differently, so the definition belongs beside the calculation.

Imagine a product normally sells for ₹1,000, costs ₹700 to purchase and incurs ₹50 of variable fulfilment cost. It contributes ₹250 per completed sale.

During a promotion, the seller funds a 10% discount. The net selling price falls to ₹900, while purchase and fulfilment costs stay unchanged. Contribution becomes ₹150.

Per completed unit	Normal sale	Promotional sale
Net selling price	₹1,000	₹900
Product cost	₹700	₹700
Variable fulfilment	₹50	₹50
Contribution	₹250	₹150
Contribution as a share of net sales	25%	16.67%

The selling price fell 10%, but contribution per unit fell 40%. The denominator is different: a ₹100 reduction is a large share of the ₹250 that was previously left.

Forty percent more units can still leave less contribution

Suppose the business normally sells 100 units. Total contribution is 100 × ₹250 = ₹25,000.

The promotion lifts completed sales to 140 units, a 40% increase. Total contribution is now 140 × ₹150 = ₹21,000, a 16% reduction. Net sales rise from ₹1,00,000 to ₹1,26,000, even as total contribution falls.

Hypothetical rupees of contribution before fixed costs, financing and taxes. Normal: 100 × ₹250. Promotion: 140 × ₹150. Not reported company data.

To preserve ₹25,000 of contribution at ₹150 a unit, the business needs approximately 166.67 units, or 66.67% more volume. With whole units, at least 167 are required to meet that amount.

The spreadsheet formula is =old_contribution/new_contribution-1. It applies only when both amounts are positive and fixed costs are unchanged. If each extra order makes a negative contribution, scaling the same economics does not solve the loss.

Added marketing changes the hurdle again

If the promotional campaign also incurs ₹5,000 of additional fixed marketing expenditure, it needs ₹30,000 of contribution to leave the original ₹25,000 after that added cost.

At ₹150 per unit, that requires 200 units, double the original volume. This is a separate scenario: do not deduct the ₹5,000 twice by putting it into both variable unit costs and fixed campaign costs.

A promotion can still serve other purposes, such as clearing ageing stock or acquiring repeat customers. Those possibilities should be evaluated separately. Future repeat purchases are assumptions until observed, not earnings already earned by the current campaign.

Count completed sales after expected returns

Orders placed, parcels dispatched and products retained by customers are different counts. Returns can reverse sales and create recovery costs; cancellations can prevent an order from becoming a sale at all.

For entities applying Ind AS 115, ICAI’s teaching material explains that expected product returns affect recognised revenue and involve a refund liability and a separate recovery asset. The details depend on the transaction and estimates, not a universal rule to subtract a fixed return percentage. ICAI material, pages 100–104.

Do not describe the full value of newly placed orders as realised revenue. Wait for the applicable disclosures and distinguish estimated returns from completed returns.

What a useful festive review contains

Preserve the number of completed sales, net realization, offer-funding split, return assumptions and cost definition. Compare like products and periods. A move into cheaper categories can alter average prices even without deeper discounts.

Keep margin percentage and absolute contribution separate. A lower margin can coexist with higher total earnings if enough profitable volume is added; a higher revenue figure can coexist with lower earnings if unit economics deteriorate.

Altys helps researchers organise source-linked financials, operating disclosures and evidence for these reviews. Where the business has not disclosed a cost or funding split, the workflow should preserve the gap. It should not replace it with an AI-generated certainty.

Continue with Diwali sales versus quantities, calendar alignment and inventory and cash collections.
