Why cutting marketing at year-end seems to work until the following quarter

A marketing budget cut made at the end of the year seems to work because the revenue of the following months still comes from leads generated before the cut. The expense drops in the same month, and revenue stays similar for a while. The effect shows up later, within the sales cycle, when the emptied pipeline (the portfolio of open opportunities) reaches closing and nobody connects the drop to the November decision.

The risk of reading the result too early was already pointed out by Les Binet and Peter Field in the study The Long and the Short of It, published by the IPA, the British institute of advertising agencies. The authors warn that using very short-term metrics as the main measure of performance has dangerous implications for long-term results.

Why today's revenue is the marketing of a few months ago

A month's revenue comes, in large part, from leads that entered one sales cycle earlier. Sales cycle is the average time between a lead's entry and the signed contract. If it is 90 days in your operation, February's sale almost always began in a November campaign.

• In the month of the cut: spending drops, and sales close with the leads that were already in the funnel.
• During the cycle: fewer leads come in, but closing still lives off the old opportunities, and the report shows lower cost with similar revenue.
• After the cycle: the old opportunities run out, the new ones are few, and revenue falls.

That is why the cut seems to have worked. The margin in November and December improves, and the drop only arrives when the cycle ends, often in another quarter and another discussion. In long sales, the same lag distorts the cost of acquisition, as we showed in the calculation of CAC in complex sales by cohort.

How to estimate when the marketing budget cut will show up

To estimate when the cut will show up, you need two numbers: the average sales cycle and the conversion rate of each funnel stage. The cycle tells you when the drop arrives. The conversion tells you how big it will be.

1. Calculate the average sales cycle by channel, from lead entry to contract.
2. Estimate how many fewer leads the cut will generate per month, using the current cost per lead of each channel.
3. Multiply those leads by the end-to-end conversion, from lead to sale.
4. Shift the result by the average cycle: the loss of sales begins in the month of the cut plus the cycle.

Imagine a hypothetical operation with an average cycle of 90 days and a 2% conversion from lead to sale. If the cut removes 500 leads per month starting in November, the calculation indicates 10 fewer sales per month starting in February. That is the number that needs to enter the decision, next to November's savings, using the same logic as revenue forecasting with funnel data.

What to look at before cutting

Before cutting, look at the open opportunities by source channel and the time each channel takes to reach a sale. These two cuts of the data show which channels sustain closing in the coming months.

• Open opportunities by channel: how many are in the funnel today and at which stage. The channel with the most opportunities at an advanced stage is the one that weighs most in the next quarter.
• Time to sale by channel: long-cycle channels, such as events and referrals, take longer to show the effect of a cut, and also longer to recover from it.
• Cost per sale, next to cost per lead: the cheap-lead channel may be the one that sells the least, and the expensive one may be the one that sustains revenue.

With these numbers, you can cut first where the cost per sale is high and the funnel is empty, preserving the channels that feed closing in the coming months. It is the same comparison that supports the split of the 2027 marketing budget by channel.

How to bring this calculation to the 2027 budget meeting

In the 2027 planning meeting, present the marketing budget cut in two lines: the month's savings and the revenue that stops coming in after the sales cycle. That way, leadership compares the two things on the same page.

1. The expected savings from the cut, month by month.
2. The estimate of fewer sales and revenue, shifted by the average cycle.
3. The month in which the drop should show up in closing.
4. The indicator that will show beforehand whether the estimate is right: new opportunities per month, by channel.

The fourth item is what protects the decision. If new opportunities fall sooner than expected, there is still time to correct the budget before the quarter closes.

To organize the conversation, it is worth following the five blocks for presenting marketing results. A guide to marketing planning 2027 helps fit this calculation into the year's review calendar. In the same meeting, write the marketing goal in opportunities and sales, as we explain when covering marketing and sales goals, so that the effect of any cut appears in the right report.

Frequently asked questions

Does cutting the marketing budget reduce revenue right away?

Most of the time, revenue does not fall in the same month. The revenue of the following months comes from leads generated before the cut, and the drop appears after one sales cycle, when the old opportunities run out.

How do I find out my operation's sales cycle?

Calculate the average number of days between lead entry and signed contract, across the sales of recent months. The calculation requires the CRM to store the lead's entry date and the sale date.

Is there a safe way to cut the marketing budget?

The safest cut starts with channels that have a high cost per sale and few open opportunities. Track new opportunities per month, by channel, to see the effect before closing.
