Eight percent. That is the median share of recurring revenue that private B2B SaaS companies put into marketing, from a March 2026 survey of more than 1,000 of them, alongside 15% going into selling 1. It is a real number and a poor target, because the companies inside it are running two different businesses, and only one of them looks like yours.
Who is inside that median
The same survey found equity-backed companies spending roughly twice what bootstrapped ones spend on marketing, and it found bootstrapped companies growing a median 20% a year against 25% for the venture-backed 1. Double the marketing budget, five extra points of growth.
That is a deliberate trade, and it is a rational one when the money came from investors who are measuring speed and have already priced in the losses. It is a terrible trade when the money came from your own customers, because you are paying double for growth you then have to finance out of cash flow while the funded company finances it out of the last round.
So the first question in setting a SaaS marketing budget is not what percentage to spend. It is whose balance sheet you are copying when you spend it.
Payback is the constraint the percentage hides
Median payback on customer acquisition in B2B SaaS now runs 16 months, down from 18, with the top quartile recovering in six months or less 2. In owner terms, the median company spends a dollar today and finishes getting it back a year and a half from now. Everything in between is a hole in the bank account that has to be funded by something.
Price sets most of that. Companies selling under $5,000 a year per customer get their money back in about 11 months, while companies in the $50,000 to $100,000 range wait 22 2. A cheap product returns cash faster and needs less of it working at once. An expensive one takes nearly two years to repay each sale, which is survivable with a round in the bank and fatal without one.
Here is the calculation worth putting on a whiteboard. Take your planned monthly marketing spend, multiply it by your payback in months, then halve it. That is roughly how much of your cash is out in the field, unrecovered, at any given moment once the machine is running. Five thousand a month at a 14-month payback means about $35,000 permanently outstanding. If that number is larger than what you can lose without changing your hiring plan, the budget is too big, whatever the percentage says.
Run it on your own product before you run it on a benchmark
Our published band for SaaS puts a lead between $40 and $110 with a median of $67, and 18% of those leads typically become customers, which puts a customer at about $372 in advertising at the median and $611 at the top of the band. Those are the numbers behind the lead cost calculator, and they are the input most founders skip straight past.
Now a worked version, with the assumptions named so you can swap in your own. Say the product is $39 a month and 70 cents of every subscription dollar survives hosting and support, so each customer contributes $27.30 a month. At the $372 median acquisition cost, that customer pays you back in 13.6 months. Assume 6% of customers cancel each month, which gives an average life around 17 months, and the whole relationship returns about $456 against $372 spent. You made $84 per customer, and you waited a year and a half to make it.
That is a business that cannot buy growth. It can be a fine business, but the money has to come from somewhere other than paid acquisition until either the price goes up or the cancellations go down. Change one variable and it flips: at $199 a month with the same margin and the same $372 lead cost, the customer is paid for in under three months and paid advertising becomes the cheapest thing on your list. Nothing about the marketing changed. The price did.
Below about $1 million in recurring revenue, don’t hire a paid media agency
Including us. Eight percent of $1 million is $80,000 a year, or roughly $6,700 a month for all of marketing. Our Starter tier is $2,500 a month on the services page, which would take 37% of that budget before a single ad runs, and our own marketing cost calculator shows that below about $1,500 a month in ad spend any competent management fee consumes more than half the money. There is no fee structure that repairs those ratios, and a cheaper agency at $900 a month is still taking a quarter of your marketing budget to run an account nobody senior will open.
The deeper reason is timing. At a 16-month median payback, a company with nine months of runway cannot afford a paid acquisition channel at all, because the money leaves this quarter and comes back after the fundraise you are trying to avoid needing. Paid media is a cash-flow instrument before it is a growth instrument, and early-stage SaaS has the least cash flow of any business we work with.
Put the money into two things instead. Founder-led selling to a named list of accounts you can research by hand, which is how you discover the language buyers use before you pay to broadcast the wrong version of it. And activation: the gap between a signup and a customer who has done the thing your product is for. Every point you gain there lowers what a customer costs you without buying anything. Come back to agencies when you know who buys, why they buy, and what a customer is worth over a year, which is usually somewhere past $1 million in recurring revenue and past $5,000 a month in ad spend.
The bigger budget line is the one nobody calls marketing
Selling takes 15% of recurring revenue at the median against marketing’s 8% 1. Nearly two dollars of people who follow up for every dollar of demand created. Founders who move money between those lines as though they were interchangeable end up with a full pipeline and nobody working it, which shows up in the ad account as a rising cost per customer and gets blamed on the ads.
The higher your price, the more this matters. At $50,000 to $100,000 a year per customer, payback stretches to 22 months 2 precisely because those deals are closed by humans over months of conversation. In that world the job of a paid channel is booking qualified meetings for people who are paid to close, and judging it on signups will get a working channel killed. That distinction shapes how we structure the accounts we run for B2B software companies.
Sixteen months is the median and six months or less is the top quartile 2. Until you can say which of those two numbers your own company is nearer, every percentage of revenue you read, the 8% included, is a description of someone else’s bank account.
