Festive Season Ads Budget Plan 2026: Amazon, Flipkart and Quick Commerce

The Indian festive season is not one event but a ten-week run from Navratri to Diwali, across three kinds of channel: Amazon's Great Indian Festival, Flipkart's Big Billion Days and the quick commerce apps that take the last-minute basket. Most brands set one festive ad budget and then let the platforms take it in the order they ask for it. This playbook is the alternative: a way to split rupees across September to November by phase and by channel, with ACoS and ROI targets that loosen and tighten as the season moves, plus the countdown, sale-week and post-season checks that keep the plan honest. It is a 2026 playbook refreshed yearly; every date is in the "This year's dates" note. See our marketplace ads management service if you would rather the season were run for you, and our Amazon fees guide for the fee stack that sets your break-even.

How do you split the festive budget by phase?

Take a brand that normally spends ₹3,00,000 a month across Amazon, Flipkart and quick commerce ads, and has set aside ₹12,00,000 for the ten weeks from mid-September to the week after Diwali. The phases below follow the shape of demand: a run-up where clicks are cheap and rank is built, the twin marketplace sales in the second week of October where clicks are dearest, a middle stretch through Navratri and Dussehra, the Dhanteras and Diwali week where quick commerce peaks, and a cool-down.

The targets are expressed relative to break-even because break-even is the only number that is yours. A product netting 25% after fees breaks even at a 25% ACoS on Amazon and a 4x ROI on Flipkart; loosening by five points in phase two means accepting a 30% ACoS on that product for one week to hold rank, and tightening in phase five means demanding 20%. Our Amazon ads guide and Flipkart ads guide explain the metrics on each platform. Use TACoS for the season as a whole: total ad spend against total sales including organic, because the point of loosening in the sale week is the organic lift afterwards.

How do you split the budget by channel?

These are starting shares for a brand that sells across all three. If your category is smartphones or large appliances, weight the marketplaces; Redseer found those categories contributing 60% to 65% of festive 2025 GMV. If it is food, gifting, home or personal care, weight quick commerce, where Redseer saw growth above 120% through the season and Storyboard18 quoted conversion rates of 3% to 8% against 1.5% to 3% on traditional digital. Whatever the split, reallocate weekly on stock and efficiency, not on the plan.

What does the four-week countdown to the marketplace sales look like?

What do you check during the season?

• Every two to three hours on early-access days and day one: spend against the day's plan by platform, deal status, Buy Box or winning offer, stock cover.
• Daily: ACoS, ROI and quick commerce ROAS by campaign against the phase target for that SKU; cut placements below threshold; move budget with stock across platforms.
• Weekly: re-cut the channel split on actual efficiency and availability; a channel that is out of stock gets no budget however good its plan share looked.
• Stock rule: pause ads on any SKU under three days of cover on marketplaces, or under 80% store availability on quick commerce.
• Phase changes: tighten or loosen targets on the dates in the plan, not when the numbers feel good; the plan exists so that the sale-week ACoS does not become the season's ACoS.

What does the post-season week look like?

1. Restore bids and budgets within 48 hours of Diwali on every platform; festive bids on normal traffic are the most common margin leak of November.
2. Reconcile ad spend against settlements. Match invoiced ad spend and its 18% GST against the platform statements; claim input credit; check that deal fees and coupon costs are in the same ledger as ad spend so the season's true TACoS is visible.
3. Returns and clearance. Budget around 15% returns on fashion and lifestyle (Techqueto's checklist number); clear festive packs through the platforms' own post-festive offers with a tight phase-five ACoS rather than deep bids.
4. Retro by phase. Spend, sales, ACoS or ROI, and TACoS by phase by channel, against the plan; stock-out hours; the organic lift in the four weeks after. This page is next year's plan with the numbers filled in.

What went wrong for brands last year?

• One budget, no phases. Brands that set a single festive budget spent most of it in the opening week of the marketplace sales at peak CPCs and had little left for Dhanteras, when gifting and quick commerce peaked. The phase plan above is the fix.
• Quick commerce budget arrived late and paid the premium. Storyboard18 reported brands shifting 15% to 20% more digital spend to quick commerce for the season and placement rates up 30% to 40% in the Diwali weeks; the brands that booked in the last week paid the premium for shelves that were already short.
• Fashion planned to the headline number. Redseer's first-leg read put overall growth at 20% to 22% but fashion in low single digits; fashion brands that budgeted ads to the headline over-spent into a category that was not growing.
• The GST change mid-preparation. Medianama reported that the September 2025 GST rate merger left sellers repricing stock and delaying decisions in the run-up; ad plans built on old prices had to be redone in the busiest fortnight.

Software or agency for the season?

A ten-week plan with five phases and three channels is a lot of daily bid and budget edits. Below roughly ₹50,000 a month of spend, the platform consoles and a weekly routine are enough. Above that, rule-based software such as BlooprintAI (Flipkart and Shopsy ads at ₹12,999 a month, Amazon India and UAE ads at ₹14,999 a month, 7-day trial; other marketplaces coming soon) automates the phase changes and search-term work, and a managed service owns the outcome across every channel including quick commerce. Either way the method is the same: break-even per SKU, targets by phase, budget that follows stock.

FAQ

How much should I budget for festive ads? There is no published benchmark. A workable rule is three to four times normal monthly spend spread across the ten weeks, weighted to the marketplace opening week and the Dhanteras to Diwali week, and never spent on SKUs without stock.

What ACoS should I accept during the sale week? Up to about five points above your break-even on hero SKUs for the opening week only, to hold rank; back to break-even in mid-season and five points below in the cool-down.

How should I split between Amazon, Flipkart and quick commerce? For a brand on all three, roughly 40%, 35% and 25% across the season, with quick commerce taking up to 45% of the Dhanteras and Diwali week. Weight by category and reallocate weekly on stock.

Do quick commerce ads really cost more at Diwali? Storyboard18 reported premium placements at 30% to 40% above normal months in the Diwali weeks, with brands moving 15% to 20% more digital budget to the channel.

When do I restore normal bids? Within 48 hours of each sale ending, and within 48 hours of Diwali for the season; festive bids on normal traffic are the most common November margin leak.

Should I measure the season on ACoS or TACoS? Both: ACoS by phase for daily decisions, TACoS for the season, because the organic lift after the sale week is the return on the loosened targets.
