Google names no fixed minimum
Google's budget guides give no fixed rupee amount you must spend. You choose an average daily budget for each campaign, based on your goals and what you are comfortable spending each day. Google's own tip is to start small, and to check your account daily after you set a new budget. That freedom helps, but it also means nothing stops you from setting a budget too small to learn anything. A tiny budget buys too few clicks to show whether the ads work. The right number comes from your costs and your margin, not from a rule. The sections below show how to work it out.
How the average daily budget works
The average daily budget is an average over the month, not a hard cap for each day. Google spends more on days when clicks and conversions are more likely, and less on quiet days. For most campaigns, one day can cost up to two times the average daily budget. Over a month, you are never charged more than 30.4 times it. That figure is simply the average number of days in a month. So a busy Saturday may spend double and a slow Tuesday may spend little, but the month stays inside your limit.
Example: daily budget to monthly limit
| Average daily budget | Most it can spend in a day | Most you pay in a month |
|---|---|---|
| ₹300 | ₹600 | ₹9,120 |
| ₹500 | ₹1,000 | ₹15,200 |
| ₹1,000 | ₹2,000 | ₹30,400 |
Work back from cost per click
Start from the order, not the budget. Here is a made-up example, not a benchmark, so use your own numbers. Say a click costs you ₹10, and 2 in every 100 visitors buy. You need 50 clicks for one order, so each order costs ₹500 in ads. If you want 30 orders a month, you need 1,500 clicks, or ₹15,000. Divide that by 30.4 and you get an average daily budget of about ₹493. With cost-per-click bidding, you pay for each click. Your actual cost per click is often lower than your maximum bid.
Check the order cost against your margin
A budget only works if each order pays for itself. Work out your margin before you open Google Ads, not after. In the example, one order costs ₹500 in ads. If you keep ₹400 after the product, packing and shipping, every sale loses money, however many you get. Then you need a cheaper click, a better product page or a bigger order before you spend more. On COD, count only delivered orders, because a returned parcel earns nothing. Your real cost per order is your ad spend divided by your delivered orders, not by the orders placed.
Start small, then scale what works
Begin with one campaign on your best sellers, with a budget you can hold for a few weeks. Maximize Clicks is Google's simplest automated bid strategy. You set the average daily budget, and Google sets the bids. Later, your budget settings can show a recommended budget, based on your results, typically from the past 15 days. Raise the budget only when your cost per delivered order sits below your margin. Increase it in steps, check results weekly, and pause what loses money.
Keep one view of the results
Google Ads reports clicks and conversions, but your store knows what was delivered and paid for. Check both each week. The Storemate's sales report shows your revenue trend and order status in one place. So you can set each week's ad spend against the orders that actually landed. If a campaign cannot reach a cost per order you can afford after a fair test, stop it and try another product. Let the numbers, not a guess, decide when the budget grows.
