How Much Should I Spend on Meta Ads?
Short answer
Enough for each ad set to reach roughly 50 conversions per week, which is what Meta's delivery system needs to exit the learning phase reliably. Work it out from your own numbers: 50 multiplied by your current cost per conversion, multiplied by 4.3, gives a realistic monthly minimum. For most Indian D2C brands that lands between ₹1.5L and ₹5L per month.

Start from the learning phase, not from what you can afford
Meta's delivery optimisation improves as it accumulates conversion events. The widely used benchmark is around 50 conversions per ad set per week before delivery stabilises. Below that, the system keeps exploring, costs stay volatile, and the results you see are only weakly related to whether your creative or targeting is any good.
So the first budget question is not what you want to spend. It is what spend is required for the account to produce a readable signal at your current conversion cost.
The calculation
Take your current cost per purchase or per lead. Multiply by 50 for the weekly requirement, then by about 4.3 for the month. If you do not have a cost per purchase yet, estimate it from your average order value and an assumed conversion rate of one to two percent.
A brand with a ₹600 cost per purchase needs roughly ₹1.3L a month for one ad set to learn cleanly. A brand at ₹2,000 per purchase needs around ₹4.3L. This is why high-ticket categories cannot test on small budgets, and why they often optimise on an earlier event such as add-to-cart or lead instead.
If the number is out of reach
Three legitimate options, in rough order of preference. First, optimise for a cheaper event higher in the funnel (add-to-cart, initiate checkout, a lead) which generates more volume for the algorithm, accepting that it is a proxy rather than the real goal.
Second, consolidate. One ad set with the full budget will learn; four ad sets splitting the same budget will not. Fragmentation is the most common self-inflicted budget problem in small accounts.
Third, narrow scope. One product, one geography, one offer. Concentration produces signal; spreading a small budget across a catalogue produces noise.
How to scale without breaking it
Large sudden budget changes push a campaign back into learning. The conventional guidance is to increase by no more than about 20 percent at a time, then allow two to three days to stabilise before increasing again. In practice, well-established campaigns with a lot of conversion history tolerate larger jumps than newer ones.
Watch cost per result and frequency together as you scale. Rising cost with rising frequency is creative fatigue, not a budget ceiling: the answer is new creative, not a smaller budget.
When to stop increasing
When incremental spend stops producing incremental profit. If moving from ₹5L to ₹7L brings the blended CAC above what your margin and repeat rate can support, you have found the current ceiling of the account rather than a temporary dip.
Raising that ceiling comes from better creative, better conversion rate or better retention economics, not from bidding harder into the same audience.

What is the absolute minimum to run Meta Ads?
Technically a few hundred rupees a day will run. Practically, for a business trying to learn anything reliable, ₹1,000 to ₹1,500 a day is a realistic floor in most Indian consumer categories, and lower budgets need to optimise for a cheaper event to generate enough volume.
Should we increase budget on a winning campaign?
Yes, but in steps of roughly 20 percent with two to three days between increases, so the campaign does not re-enter learning. Doubling a budget overnight frequently destroys the performance you were trying to scale.
Why did our results get worse after increasing spend?
Usually one of three things: the campaign re-entered the learning phase after too large a jump, frequency rose and the creative fatigued faster, or you exhausted the most responsive part of the audience and are now reaching colder people. The diagnosis differs and so does the fix.
Should budget be at campaign or ad set level?
Campaign budget optimisation is the sensible default for most accounts. It lets Meta move money to whichever ad set is performing. Ad set budgets make sense when you need to guarantee spend on a specific audience for testing or business reasons.
