Your Amazon ads daily budget should be the ad sales you want each day multiplied by your target ACoS. Enter both and this calculator returns the daily budget, the monthly total, and, if you add your average CPC, how many clicks a day that budget buys. It turns a sales goal into a number you can type into Campaign Manager.
Target daily ad sales is the revenue you want ads to bring in per day, not total sales. Target ACoS should come from your margin (see the target ACoS calculator).
Worked example: you want ₹10,000 of ad sales a day at a 25% target ACoS. The daily budget is 10,000 × 25% = ₹2,500, about ₹76,000 a month. At a ₹10 CPC that buys 250 clicks a day; at a 10% conversion rate and a ₹400 average order, that is 25 orders and ₹10,000 of sales, which confirms the plan hangs together.
If the check does not add up, the target is unrealistic at current CPC and conversion, not the budget. Either the ACoS target, the sales goal or the conversion rate has to move.
A total daily budget still has to be divided. A split many sellers start with, then adjust to results:
| Campaign type | Share to start with | Why |
|---|---|---|
| Exact-match proven keywords | 40 to 50% | Most predictable ACoS; never let them run out |
| Auto and broad discovery | 20 to 25% | Finds new search terms to harvest |
| Product targeting | 15 to 20% | Competitor and complementary ASINs |
| Sponsored Brands or Display | 10 to 15% | Brand visibility and retargeting |
The shares are a starting point, not a benchmark. After two weeks move budget towards the campaigns with the lowest ACoS that run out of budget before evening.
BlooprintAI lists every campaign's spend against budget, ACoS and sales in one table, so the ones that run out early and convert well are easy to find. You change budgets in bulk, with a summary first and a log after. Budgets are never changed automatically.

Amazon lets you start low, but a budget that buys fewer than about 20 clicks a day at your CPC gives too little data to judge a campaign within a couple of weeks.
For your best campaigns, yes. If a low-ACoS campaign runs out before evening, it is losing sales; raise its budget before raising bids.
Amazon can exceed a campaign's daily budget on some days while keeping the month within daily budget × days in the month. Check the monthly total, not one day.
No. Campaign budgets are before GST; Amazon Ads invoices in India add 18% GST on top.
