Small-business marketing budget: a monthly template and example

Build a small-business marketing budget with a worked €3,000 example. Track commitments, forecast overspend and decide what to fund next without guesswork.

A useful marketing budget separates what you approved, what you spent and what you are still committed to pay. A channel split alone cannot tell you whether you can afford the next campaign.

This template is for a small business planning its next month. It deals with spending control and reallocation; use our 90-day marketing plan to choose the wider commercial priorities. The €3,000 example below is fictional, not a recommended minimum, an agency price or a client result.

1. Set a cash ceiling before dividing the budget

Choose the amount the business can commit without compromising payroll, delivery or existing obligations. Include payment timing: customers paying in 60 days will not fund an invoice due next week. Ask the person responsible for finances to validate the ceiling.

Then write one purpose for the month, such as testing demand for one service. List the people available to produce the work and handle enquiries. A budget that buys attention without enough capacity to respond can create an operational problem.

Avoid copying a universal percentage of revenue. A launch, a seasonal business and an established service company have different constraints. Use your own baseline and write uncertain assumptions down.

2. Make costs visible before assigning channels

Separate media, management, production, website work, measurement and tools. Record internal hours beside cash expenses so a supposedly free activity does not hide workload. Keep one-time setup separate from recurring work, and document the scope of each supplier invoice to prevent double counting.

The Australian government's marketing-plan guidance connects objectives, activities and budget. Our application here is a row for each deliverable with a named owner and a spending limit. This is an operating template, not a required accounting format.

Use a consistent tax basis agreed with your finance owner. Keep actual payment dates in a separate cash view if they differ from the period in which work is delivered.

3. Copy the monthly budget table

This hypothetical business approves a €3,000 ceiling. The review takes place partway through the month. “Committed” means unpaid work or spend already agreed; “remaining estimate” means additional work still needed and not already committed. Never count the same invoice in both columns.

Forecast total = spent + committed unpaid + remaining estimate. Over / under = forecast total − approved. Positive variance means that row is above plan. Negative variance is headroom, not automatically permission to spend.

The example has spent only €1,300, but its expected final cost is €2,800. It has €200 of forecast headroom, not €1,700 available for a new experiment. Search is €100 above its original allocation; the owner must approve using part of the reserve or reduce its remaining spend.

The government budgeting guide distinguishes a spending plan from a forecast based on current information. Keep the approved column intact and update the forecast: overwriting the plan would hide the variance you need to explain.

4. Attach a decision to each spending row

Add an owner, objective, evidence and review date beside the financial table. Use our CPC, CPA and CAC guide to keep click costs separate from full customer acquisition costs. Use the same cost scope when comparing periods.

These are decision prompts, not automatic stop rules. Set the actual evidence threshold around the business's economics and sales cycle. A useful experiment has one question, an affordable limit, an owner and a review date; it does not need a fixed percentage of the overall budget.

5. Review weekly, then rebuild next month's forecast

Check delivery problems promptly and update actual spend, commitments and remaining estimates weekly. For performance decisions, allow time for enquiries to mature into customer outcomes. Compare acquisition cohorts rather than dividing this week's spend by customers generated months earlier.

At month end, explain variances, carry unpaid commitments forward and separate reusable setup work from ongoing activity. Choose what to maintain, repair, test or stop. The weekly marketing scorecard supports this review; the budget table records what the resulting decision costs.

Before you approve the next month

• Confirm the cash ceiling and payment dates with the finance owner.
• Include media, production, management, tools and internal capacity.
• Reconcile every commitment so it appears once.
• Keep approved amounts separate from the latest forecast.
• Link each major expense to an owner and a useful decision.
• Check sales capacity and mature customer outcomes before scaling.
• Record who approved any reserve use or spending increase.

How much should a small business spend on marketing?

There is no single amount this template can establish. Start with affordable cash, the outcome you need to investigate and the resources required to deliver the test. If those do not fit, narrow the scope rather than invent a revenue promise.

Should the whole reserve be spent?

No. A reserve can remain unused. Release it only for a specific approved purpose after checking the revised total and cash timing.
