One of the first questions clients ask us is: *"How much money do we need to start Google Ads in Mysuru or Bengaluru?"*
Some agencies say: *"Give us ₹10,000 and we'll bring you 100 leads."* Others demand a minimum of ₹1,00,000 per month just to manage the account.
Neither answer is helpful without understanding the unit economics of your business. Setting a digital ad budget is not guesswork—it is a straightforward mathematical calculation based on your industry's cost-per-click and customer deal size.
Here is a practical, honest framework to set a realistic Google Ads budget in India.

The Formula: How to Calculate Your Minimum Testing Budget
To know if a Google Ads campaign works, you need enough data to generate statistically meaningful conversions.
In local search, a well-built landing page typically converts **8% to 15% of clicks** into an enquiry (phone call, form fill, or WhatsApp chat). That means you need approximately **10 to 12 clicks to generate one qualified enquiry**.
To generate 20 to 30 enquiries per month—enough to keep a local sales team busy and measure real sales closures—you need between **200 and 300 targeted clicks**.
The Math:
$ ext{Monthly Budget} = ext{Target Clicks (250)} imes ext{Average Cost-Per-Click (CPC)}$
Let's apply this to real Karnataka market rates:
| Industry & Region | Est. Cost-Per-Click (CPC) | Clicks for 25 Leads | Minimum Monthly Ad Spend |
|---|
|---|---|---|---|
| **Residential Interior Design (Mysuru)** | ₹40 – ₹70 | 250 clicks | ₹12,000 – ₹18,000 |
|---|---|---|---|
| **Commercial Solar EPC (Karnataka)** | ₹60 – ₹110 | 250 clicks | ₹18,000 – ₹28,000 |
| **Specialized Healthcare / Clinic (Mysuru)** | ₹30 – ₹60 | 300 clicks | ₹12,000 – ₹18,000 |
| **B2B Industrial Machinery / Tooling** | ₹75 – ₹140 | 200 clicks | ₹18,000 – ₹28,000 |
| **Corporate Legal / Accounting (Bengaluru)** | ₹120 – ₹220 | 200 clicks | ₹30,000 – ₹45,000 |
For most service businesses in Tier-2 cities like Mysuru, a **monthly ad spend of ₹15,000 to ₹30,000** (plus management fees) is the ideal testing threshold. In competitive metros like Bengaluru, plan for **₹35,000 to ₹60,000**.

How to Measure Your Real Return on Ad Spend (ROAS)
Do not judge advertising success by likes, clicks, or raw enquiry counts. Measure the **Closed Deal Value**:
Real-World Example: Modular Furniture Manufacturer in Mysuru
- **Monthly Ad Spend:** ₹22,000
- **Agency Management Fee:** ₹15,000
- **Total Monthly Investment:** ₹37,000
- **Clicks Generated:** 380 clicks at ₹58 avg. CPC
- **Enquiries Received:** 34 phone calls & WhatsApp chats (8.9% conversion rate)
- **Qualified Site Visits Conducted:** 12 homeowners
- **Orders Closed:** 2 complete interior projects
- **Total Revenue Generated:** ₹7,40,000
- **Gross Profit Margin (30%):** ₹2,22,000
- **Net Return:** ₹2,22,000 profit - ₹37,000 marketing cost = **₹1,85,000 net gain**.
When the numbers are clear, marketing stops feeling like an expense and becomes an investment.

3 Budget Traps to Avoid
1. **Starting with ₹200 per day:** Spending ₹200 a day in an industry where clicks cost ₹60 means your budget runs out after 3 clicks at 9:30 AM. You never collect enough data to optimize. 2. **Ignoring Management & Creative Costs:** Running ads requires landing page design, copywriting, tag tracking, and weekly optimization. Budget for professional execution, not just raw platform spend. 3. **Pausing After 4 Days:** Google's smart bidding takes 7 to 10 days to learn which search times and user demographics produce conversions. Pausing after 4 days guarantees you pay the learning cost without reaping the optimization benefits.

Frequently Asked Questions
Can I reduce my ad budget once SEO starts working?
