Google Ads Planning
How much should a small business spend on Google Ads? Not ₹10,000, ₹50,000, or ₹1 lakh — your ideal budget depends on expected CPC, required clicks, conversion rate, target customers and the acquisition cost you can afford.
Expected CPC × Required Clicks × Conversion Rate × Target Customers × Acceptable CAC
Short Answer
Don't pick a budget — derive it: required customers ÷ lead-to-customer rate ÷ landing-page conversion rate × average CPC = estimated ad budget.
The biggest budgeting mistake is choosing an arbitrary round number and spreading too little spend across too much — budget must be evaluated against your business economics, not spent and hoped for.
No Universal Number
There is no universal minimum budget. A realistic starting point depends on your industry, location, average cost per click, search demand, website conversion rate, lead-to-customer conversion rate, customer lifetime value, target cost per acquisition, and campaign objective. A local service business operating in one neighbourhood may need a very different budget from a B2B company targeting customers across India — the correct budget should be calculated from expected acquisition economics, not copied from a competitor.
The Formula
Example: you want 20 new customers. Your sales team converts 20% of qualified leads → you need 100 leads. Your website converts 10% of clicks into leads → you need 1,000 clicks. At ₹30 average CPC, that's roughly ₹30,000. This is a planning estimate, not a performance guarantee — actual results depend on competition, targeting, account quality, tracking and sales performance.
How many new customers do you want this month?
What share of qualified leads does your sales process close?
What share of clicks does your page turn into leads?
What do you expect to pay per click in your market?
A planning estimate — not a performance guarantee.
Illustrative Ranges
These are planning ranges to orient your thinking, not guaranteed performance benchmarks. Your actual budget should be calculated from your CPC and conversion economics.
| Business Type | Illustrative Monthly Budget | Approx. Daily Budget |
|---|---|---|
| Hyperlocal Service Business | ₹15,000–₹40,000 | ₹500–₹1,300 |
| Competitive Local Service Business | ₹30,000–₹1,00,000 | ₹1,000–₹3,300 |
| Multi-Location Business | ₹75,000–₹3,00,000+ | ₹2,500–₹10,000+ |
| B2B Lead Generation | ₹50,000–₹5,00,000+ | ₹1,700–₹16,500+ |
| E-commerce | Determined by revenue and ROAS targets | Variable |
Biggest Mistake
The most common mistake is choosing an arbitrary monthly budget — “let's spend ₹10,000 and see what happens.” That ignores CPC, conversion rate, acquisition cost, and required conversion volume.
Suppose your average CPC is ₹100. A ₹10,000 monthly budget generates roughly 100 clicks. At a 5% landing page conversion rate, that's approximately five leads. If your sales team closes 20% of leads, the expected outcome is roughly one customer. That may be acceptable for a high-value service — it may be completely uneconomical for a low-margin business. Budget must be evaluated against your business economics, not spent and hoped for.
Ad Spend vs Fees
Your advertising budget and agency management fee are different costs. Ad spend is money paid to Google for advertising inventory. Management fee is money paid to an agency to manage campaigns. Deltanoid uses a zero-markup-on-ad-spend model — we don't increase our fee simply because you increase your budget, which removes the incentive to recommend unnecessary spend.
Budget by Goal
Estimate expected CPC, lead conversion rate, lead-to-customer rate and customer value. Local businesses should also consider whether GBP optimisation and Local SEO can reduce long-term dependence on paid acquisition.
Spas, clinics, home services and other local service companies should measure qualified phone calls, WhatsApp inquiries, appointments and actual customers — not just clicks.
B2B campaigns often have higher CPCs and longer sales cycles. Budget planning should account for lead quality, sales-qualified leads, opportunities, close rates and customer lifetime value.
E-commerce budgets should be calculated using contribution margin, conversion rate, average order value, repeat purchase rate, target ROAS and customer acquisition cost.
