Your startup needs customers. Your bank balance needs breathing room. Somewhere between those two realities sits a question every founder eventually asks: “How much should I actually spend on marketing?”
Five per cent? Ten? Whatever is left after paying the bills?
A useful budget gives every rupee a job. It should help you learn what brings the right customers in, without spending so much that you cannot serve them well when they arrive.
Start with a percentage, then check your stage
For a startup already making sales, 5–10% of net revenue is a reasonable planning range to explore, provided margins and cash flow support it. Use that range to start a plan, then adjust it for your business. It is not a target every startup needs to reach.
For context, the Business Development Bank of Canada’s small-business marketing guidance suggests broad rules of thumb of 2–5% of revenue for businesses selling to other businesses, and 5–10% for consumer-facing businesses. Those are Canadian small-business guidelines, not a study of Indian startups.
Your circumstances matter more than the headline number. A consulting startup winning clients through referrals may need a different budget from a new consumer brand competing for attention online.
No revenue yet? Use a fixed learning budget
Ten per cent of zero still gives you zero. Before revenue, choose a cash amount you can afford to test, after protecting essential operating expenses.
For example, a founder might cap one month’s experiment at ₹10,000 to test a landing page, customer interviews and a small campaign. That is an illustration, not a recommended minimum. The right amount depends on what you need to learn and how long your cash must last.
Pick one question: “Will this audience enquire about this offer?” A small, focused experiment can be more useful than launching five channels with no clear way to judge them.
Make the maths visible
Suppose your startup generates ₹5 lakh in monthly revenue after discounts and returns, excluding GST collected. At 8%, your monthly marketing budget would be ₹40,000.
At 5%, it would be ₹25,000. At 10%, ₹50,000.
Now ask which amount your business can sustain across several months. Use a realistic recent revenue average if sales fluctuate. Do not build recurring commitments around one unusually strong month or a hoped-for funding round.
Write down the cap before the month begins. It is much easier to make sensible decisions when each attractive new opportunity has to fit an existing plan.
Include more than the advertising bill
If you spend ₹20,000 on ads and another ₹15,000 on creative, tools and agency support, your marketing spend is ₹35,000.
Count the relevant costs: content, design, website work, email software, events and the marketing share of salaries or freelance fees. Separate one-time setup costs from ongoing activity so you can compare months fairly.
Here is one illustrative split of that ₹40,000 budget: ₹20,000 for customer acquisition, ₹10,000 for useful content and creative, ₹6,000 for customer communication and retention, and ₹4,000 for experiments.
That is 50%, 25%, 15% and 10% of the marketing budget—not of revenue. Change the allocation when your evidence changes.
Check whether a new customer pays you back
Reach, likes and enquiries can tell you something. Paying customers and contribution margins tell you more about whether you can keep spending.
Imagine an acquisition campaign costs ₹15,000, including its allocated creative and tool costs, and brings 25 new paying customers. Customer acquisition cost is ₹600.
If a ₹1,000 order leaves ₹450 after its variable fulfilment, payment and service costs, that first order has not recovered the ₹600 acquisition cost. Fixed overheads still need covering too.
Repeat purchases might improve the economics, but use observed retention rather than an optimistic lifetime-value guess. A campaign that produces sales can still consume cash faster than your startup can replace it.
Increase spending after evidence improves
If an offer converts consistently, customers stay satisfied and you can fulfil more orders, test a measured budget increase. Watch whether acquisition costs worsen as you reach a wider audience.
If enquiries arrive but sales do not, inspect the offer, follow-up and buying experience before buying more traffic. If customers purchase once and disappear, investigate retention.
Keep room for trust-building work: useful explanations, customer stories, clear case studies and accurate recognition. Our article on how “award-winning” can transform your business explores that last idea. None replaces a good product or guarantees demand.
Leave your next review with three decisions
At month-end, decide what to continue, what to stop and what to test next. Check spending, new customers, contribution and cash remaining alongside your original goal.
Your marketing budget should buy useful learning today and support a business you can still afford to run tomorrow.
