TACoS Benchmarks by Category — India 2026 Report
TACoS — Total Advertising Cost of Sales — is the single most important metric for a scaling Amazon India brand, and the one most sellers do not track. Where ACoS measures ad campaign efficiency, TACoS measures whether your ad spend is growing your business or just replacing sales you would have made organically. This report presents the first TACoS benchmark study for Amazon India, aggregated across eVanik's active seller base, broken down by 10 major categories.
📊 Methodology
Data aggregated from Amazon Advertising API feeds across eVanik's active Indian seller base, anonymized at the account level. Rolling 12-month window. Brands with less than ₹50,000 monthly ad spend or less than 90 days of active advertising excluded. Sales totals include organic + advertising-attributed revenue as reported by Amazon Seller Central.
TACoS = (Total Ad Spend ÷ Total Revenue) × 100. Lower is typically better — but what counts as “good” depends heavily on the brand's growth stage (see section 5).
1. Executive Summary
- Median TACoS across all Amazon India categories: 11.8%
- Best-performing category (lowest TACoS): Books & Media — 6.2% median
- Most expensive category (highest TACoS): Beauty & Personal Care — 17.4% median
- Top-quartile brands run TACoS 35-50% lower than category median — driven by organic review velocity, brand search dominance, and disciplined negative keyword hygiene.
- TACoS spikes 28-45% during festival sales (October-November) as every seller competes for the same shoppers.
2. Overall TACoS Distribution
| Percentile | TACoS | Interpretation |
|---|---|---|
| P10 (top decile) | 3.4% | Strong organic; ads are pure scale lever. |
| P25 | 6.8% | Mature brand with efficient paid motion. |
| P50 (median) | 11.8% | Mixed paid + organic, typical scaling brand. |
| P75 | 18.6% | Heavy paid dependence; brand-building phase. |
| P90 | 27.9% | New launch or distressed account — red flag above 90 days. |
3. TACoS by Category
| Category | P25 | Median | P75 |
|---|---|---|---|
| Books & Media | 3.1% | 6.2% | 11.8% |
| Grocery & Gourmet | 4.4% | 8.1% | 14.0% |
| Home & Kitchen | 5.5% | 9.4% | 15.1% |
| Electronics & Accessories | 5.9% | 10.2% | 16.3% |
| Toys & Games | 6.6% | 11.4% | 17.8% |
| Baby Products | 7.0% | 12.6% | 19.2% |
| Apparel & Fashion | 8.1% | 13.7% | 21.4% |
| Health & Nutrition | 9.2% | 15.3% | 23.7% |
| Sports & Fitness | 9.6% | 16.1% | 24.2% |
| Beauty & Personal Care | 10.8% | 17.4% | 26.5% |
4. Why TACoS Varies So Much by Category
Books and Grocery run low TACoS because search volume is high, competition is moderate, and customers often search by specific title or brand. Ad spend is a small lever — most sales come from organic ranking.
Beauty and Personal Care run highest TACoS for the opposite reason: new-brand launches are constant, shoppers are loyal to brands they already know, and breaking through organically takes 6-12 months. New entrants pay heavily for visibility through the first year.
Apparel sits in the middle because of the RTO drag — 20-30% of apparel sales return, which inflates effective TACoS by 25-40% beyond headline numbers.
5. TACoS Targets by Brand Stage
| Stage | Target TACoS | Why |
|---|---|---|
| New launch (0-90 days) | 20-35% | Buy impressions aggressively to build review velocity and rank. |
| Scaling (3-18 months) | 12-20% | TACoS should decline month-over-month as organic picks up. |
| Mature (18+ months) | 6-12% | Ads are a scale lever, not the primary revenue source. |
| Defensive (category leader) | 3-8% | Mostly branded search spend to defend top-of-funnel. |
6. Seasonal Patterns
Amazon India TACoS is not flat across the year. Three patterns we see consistently:
- Great Indian Festival (October-November) — TACoS jumps 28-45% above annual median as every brand competes on the same keywords. Revenue spikes too, but ad efficiency degrades.
- Jan-Feb lull — TACoS typically drops 15-20% below annual median as ad competition falls off post-festivals. A good time to test aggressive scaling.
- Prime Day (July) — Less volatile than festival sales in India but still elevates TACoS by 15-25% for 10-14 days.
7. What “Good” TACoS Looks Like — 3 Brand Trajectories
Three anonymized eVanik customer trajectories illustrate healthy vs problematic TACoS patterns:
✅ Brand A — Home & Kitchen (healthy)
Month 1: TACoS 28%. Month 6: TACoS 14%. Month 12: TACoS 8%. Ad spend doubled; revenue grew 6x. Organic share of revenue climbed from 35% to 72%. Ads were a scale lever that paid back through organic lift.
⚠️ Brand B — Apparel (flat)
Month 1: TACoS 22%. Month 6: TACoS 21%. Month 12: TACoS 20%. Ad spend grew 3x; revenue grew 3.2x. Organic share barely changed. Ads were replacing organic rather than lifting it — review velocity and A+ content both lagged.
❌ Brand C — Beauty (unhealthy)
Month 1: TACoS 24%. Month 6: TACoS 31%. Month 12: TACoS 38%. Revenue growth stalled while ad spend climbed — classic cannibalization signal. Root cause: over-reliance on branded search and no category-keyword expansion.
8. How to Reduce TACoS
- Build organic review velocity. TACoS correlates inversely with review count at -0.72 across our dataset. Every 50 reviews tend to drop TACoS by 1-2 percentage points.
- Harvest exact-match winners aggressively. Exact-match campaigns run 40-60% lower TACoS than broad. See the search term report guide.
- Own your branded keywords with tight bids. A ₹4 bid on your own brand name should capture 90%+ impression share at 2-3% TACoS.
- Invest in A+ content and better main images. A 1-percentage-point conversion rate lift typically translates to 1.5-2 points lower TACoS.
- Negate waste terms weekly. See our 50 negative keywords for Indian sellers.
