The short answer: most small businesses in India should start somewhere between ₹30,000 and ₹1,00,000 a month. But that range is close to useless on its own, because the right number is not a budget at all — it is an outcome worked backwards.
Why “what should I spend” is the wrong question
Almost every owner who calls us opens with a budget. It is the wrong starting point, because a budget is an input and you are being judged on an output. The question that actually matters is: what is a customer worth to you, and how much of that are you willing to pay to acquire one?
Once you know that, the budget calculates itself.
Work backwards from what a customer is worth
Start with three numbers you already have:
- Average order value. What a customer spends with you in one transaction.
- Gross margin. What is left after the cost of the product or service.
- Repeat rate. How often they come back in a year.
If your average order is ₹3,000 at 40% margin, each sale leaves you ₹1,200. If one in three customers buys again within a year, your real value per customer is closer to ₹1,600.
Now decide what share of that you are prepared to spend on acquisition. Most healthy businesses land between 20% and 30%. At 25% of ₹1,600, your target cost per acquisition is ₹400.
If you want twenty-five new customers a month, your budget is ₹10,000 — not because that is a comfortable number, but because that is what twenty-five customers cost at a price you can afford.
The minimum that actually buys you data
There is a floor below which advertising stops being advertising and becomes guessing. Meta and Google both need a volume of conversion events before their optimisation has anything to learn from. Somewhere around fifty conversions a month is where a campaign starts behaving predictably rather than randomly.
If your target cost per acquisition is ₹400, fifty conversions means ₹20,000 a month. Spend ₹5,000 instead and you will not get a quarter of the result — you will get noise, because the algorithm never gathered enough signal to optimise against.
This is the single most common mistake we see. A business spends ₹8,000 a month for three months, concludes “ads do not work for us,” and stops. Ads did not fail. The budget never reached the threshold where the system could learn.
Fix the plumbing before you scale the spend
Here is the part nobody wants to hear: if your conversion tracking is wrong, every rupee above the minimum makes things worse, not better. You are paying the platform to optimise towards bad data, and it will do exactly that, very efficiently.
Before increasing any budget, confirm three things:
- Your conversion event fires on the actual conversion — the thank-you page or the purchase, not the page load.
- Events are deduplicated between the browser pixel and the server-side API, or you are counting the same sale twice and your reported cost per acquisition is half what you are really paying.
- The value passed back is real revenue, not a static placeholder.
We have audited accounts spending ₹4,00,000 a month where the pixel was firing on every page view. Every optimisation decision the platform made for a year was built on that. The fix cost nothing and changed everything.
A sensible starting structure
For a business starting at ₹50,000 a month, we would generally split it roughly:
- 60% to what already works — search intent or retargeting, where demand exists and you are capturing it.
- 30% to prospecting — finding people who do not know you yet.
- 10% to testing — new creative, new audiences, things that will mostly fail.
That last 10% is not optional. Creative fatigue is real and arrives faster than most people expect. If you are not testing while things work, you have nothing ready when they stop.
What good looks like after ninety days
Do not judge a campaign in week two. Give it ninety days and look for three things: a cost per acquisition trending towards your target, a stable or rising conversion rate, and enough volume that the numbers mean something. Two conversions at a brilliant cost per acquisition is luck. Sixty is a pattern.
On a recent D2C apparel account, rebuilding the product feed before touching budget took return on ad spend to 3.2x and cut cost per purchase by 61%. The spend barely moved. The data underneath it did.
The honest summary
Start at the minimum that buys you fifty conversions a month at your target cost per acquisition. Fix your tracking before you scale. Hold 10% back for testing. Judge it at ninety days, not ninety hours.
If you would like someone to check whether your tracking is telling you the truth before you increase anything, send us the account. We will look at pixel health, campaign structure and conversion setup and tell you what we find. If it is all working, we will say that too.
