How to Create a Small Business Marketing Budget That Pays Back

Two ways to set the number

Use a percentage of revenue as a starting guardrail, then check it against a bottom-up estimate based on the customers you need.

The top-down method sets marketing at a share of revenue. The right share depends on your industry, growth stage and margins, so ask your accountant or industry association for typical ranges rather than relying on a general rule. A business that wants fast growth will spend a higher share than one that wants to hold steady.

The bottom-up method is more useful. Decide how many new customers you want, estimate the cost to win each one, and multiply. Compare both numbers. If they are far apart, find out which assumption is wrong before spending a dollar.

Work backward from your goal

Start with the revenue you want, divide by average customer value to get customers needed, then apply your conversion rates to find the leads required.

This illustrative example uses round numbers. A cleaning company wants $120,000 of new yearly revenue. A typical new customer is worth $1,200 over a year. That means 100 new customers.

1. Customers needed: 100.
2. If 25 percent of leads become customers, leads needed: 400.
3. If 10 percent of website visitors become leads, visitors needed: 4,000.

Now price the route to 400 leads. If your paid channels cost about $30 per lead, the lead budget is $12,000. That is 10 percent of the new revenue goal. If it costs $60 per lead, the number doubles and the plan may not be worth it. Adjust the offer, the channel or the goal.

Know what a customer is worth

Customer lifetime value, not the first sale, tells you how much you can spend to acquire someone.

A customer who buys once at $150 is worth far less than one who returns four times a year. Estimate average order value, number of purchases per year and years retained, then multiply by gross margin to see the profit a customer brings.

If a customer brings $600 in lifetime gross profit, spending $100 to win one is a good deal. Spending $500 is not. Without this figure, budgets turn into guesses. Our marketing payback math article walks through the formula. Also see new vs. old customers, because keeping a customer often costs less than finding a new one.

Split the budget across channels

Put most of the money into channels with proven results, a smaller share into tests and a fixed portion into customer retention.

A practical split for a small business is roughly:

• Proven channels: most of the budget, covering what already brings customers, such as local search, referrals or an email list.
• Tests: a modest share to try one new channel at a time, with a defined end date and success measure.
• Retention: some money for email, loyalty offers and follow-up, since existing customers are the cheapest to sell to.
• Assets: the website, photography and review collection that make every other channel work better.

Review marketing channels to see options, and marketing strategy to pick among them.

Set tracking before you spend

Use a unique phone number, link or code for each channel and ask every new customer how they found you.

A budget you cannot measure is a hope. Set up simple tracking:

• Website analytics, with form submissions and calls counted as goals
• A distinct tracking link or code for each campaign
• A 'how did you hear about us?' question on every form and in every first call
• A monthly sheet: spend, leads, customers and revenue by channel

Calculate cost per lead and cost per customer for each channel. Stop channels that fail your test and add to those that work. This takes an hour a month and prevents months of waste.

Review monthly, adjust quarterly

Check results monthly, but make big shifts only after enough data, usually a quarter. Keep a little room to act on opportunities.

Short-term swings are noisy. A bad week does not mean a channel failed. Give new efforts at least two to three months, depending on your sales cycle, before judging them. Meanwhile, watch leading indicators: leads, calls, traffic and conversion rate.

Keep a small unallocated reserve, perhaps 10 percent, for opportunities such as a local event or a seasonal surge. Review the whole plan each quarter. Our small business budget guide shows how marketing fits into the whole.

When to fund a bigger push

If you have a channel with proven returns and the cash to scale it is missing, funding the spend can make sense when the payback is clear.

Suppose a channel brings a customer for $200 and each customer yields $700 of gross profit within six months. Spending $20,000 would bring about 100 customers and $70,000 of gross profit. In this illustrative case, even with $2,500 of financing cost, the return is strong. The risk is that returns fall as you scale, so grow in steps and watch the numbers.

ROI Funder starts with this payback math. Working capital can fund a proven campaign for businesses with 500+ FICO, 6+ months in business and $20,000+ monthly revenue. Do not borrow to test an unproven channel.
