At this pace, where does the month close?

Short answer: going over budget is rarely a decision. It is usually a pace that continued. A simple calculation on the twelfth of the month tells you what the month will close at if spending continues at the same rate, which gives you two weeks to act instead of discovering the number after the money has gone.

Why overspend happens unnoticed

Because budgets are set monthly and spending happens daily. You see today’s number and yesterday’s, and both look reasonable. The total is the thing you do not see until the month ends.

Three things raise the pace without any decision from you:

• Daily budgets rise automatically under some settings, or a new campaign was added on top of an old one rather than replacing it.
• Competition rises in a season, so cost per click rises and the same budget is consumed faster.
• A holiday or an occasion lifts two days of spend, which you treat as an exception. The total does not know about exceptions.

The calculation, and its limits

The idea is deliberately simple: take what has been spent since the start of the month, divide by the days elapsed, multiply by the days in the month. That is the projection at the current pace.

Its limit is worth stating plainly: this is a linear extrapolation, not a seasonality model. It assumes the rest of the month resembles the start of it. If your season begins next week, or you have a promotion planned, it will understate reality. Its value is early warning, not prediction.

And for it to mean anything, it is compared against last month over the same number of days, not against all of last month. Comparing twelve days against thirty is a meaningless comparison, and it is a common one.

Where MIQAS comes in

MIQAS runs this per platform and shows the month-end projection next to last month’s spend over the same number of days, so you know whether you are running faster or slower, and by how much.

The per-platform split is the part that matters. A total can look normal while one platform spends double its usual rate and another sits paused, the two cancelling each other out in the headline number.

And because revenue is calculated from your actual orders in the same dashboard, the question stops being only “how much will I spend” and becomes “how much will I spend against how much will I sell”.

What to do today

• Take month-to-date spend, divide by days elapsed, multiply by days in the month.
• Compare it against your planned budget. If it is higher, you now know by how much, with time left.
• Compare it against the same period last month, not the whole of last month.
• If the gap comes from one platform, deal with that one rather than cutting everything evenly.

An overrun is not discovered at the end of the month. It is discovered in the middle of it, if somebody is doing the arithmetic.
