"What's the minimum budget for Google Ads?" I hear this weekly. The answer depends on your industry, competition, and goals. But I can give you numbers grounded in what Indian businesses actually spend and what produces results.
The minimum viable budget
Below Rs 10,000/month, Google Ads is unlikely to generate enough data to optimize effectively. At typical Indian CPCs, that's 100-300 clicks per month — barely enough to test two or three keywords.
Rs 10,000-25,000/month: Enough for a focused local campaign targeting 5-10 keywords in a single city. You'll get 200-800 clicks and can generate 10-40 leads depending on your conversion rate. Good for testing whether Google Ads works for your business.
Rs 25,000-75,000/month: A proper working budget for most local service businesses. Enough to target multiple keyword groups, test different ads, and optimize based on data. Expect 30-150 leads per month.
Rs 75,000-2 lakh/month: Multi-campaign territory. You can target different services, run retargeting, test display ads alongside search, and cover broader geography.
Industry-specific benchmarks (India, 2026)
Average cost per click varies dramatically by industry:
- Dental clinics: Rs 15-40 per click
- Coaching institutes: Rs 10-30 per click
- Real estate: Rs 30-100 per click
- Restaurants: Rs 5-20 per click
- Law firms: Rs 40-120 per click
- IT services: Rs 25-80 per click
- Beauty/wellness: Rs 10-30 per click
Multiply your expected CPC by 20-30 to estimate your cost per lead (assuming a 3-5% conversion rate on your landing page). Then multiply by your desired number of monthly leads to get your budget.
Example: A dental clinic at Rs 25 CPC, 4% conversion rate, wanting 30 leads per month: 30 leads ÷ 0.04 = 750 clicks needed. 750 × Rs 25 = Rs 18,750/month.
Calculating your break-even
Here's the math that actually matters: how much can you spend per lead and still make money?
If your average customer is worth Rs 10,000 in revenue, and your profit margin is 40%, each customer generates Rs 4,000 in profit. If 20% of leads become customers, you can afford to spend up to Rs 800 per lead and break even (Rs 4,000 × 20% = Rs 800).
Any CPA below Rs 800 is profitable. This calculation — not industry benchmarks — should determine your budget.
Scaling budget wisely
Don't double your budget overnight. Increase by 20-30% every two weeks, monitoring whether cost per lead stays stable. Sudden large increases often spike CPCs because Google's algorithm hasn't learned how to spend the additional budget efficiently.
If cost per lead increases as you scale, you've likely hit a ceiling for your current keyword set. Add new keywords or expand geography instead of just increasing bids on existing terms.
When to increase spend
Your current campaigns are profitable with stable CPA. You have capacity to handle more leads. You've optimized your landing page and follow-up process. Your Quality Scores are 6 or above on most keywords.
When to decrease spend
Your CPA is above break-even and hasn't improved after four weeks of optimization. Lead quality is poor (many leads but few conversions to customers). You don't have capacity to handle current lead volume.
The right Google Ads budget isn't a number you set once. It's a number you adjust monthly based on performance data, business capacity, and ROI. Start conservative, prove it works, then scale what's profitable.
