How much does it cost a marketing agency to win a new client?

Multiply your cost per first meeting by the meetings it takes to win one retainer. For most agencies that is somewhere between four and eight meetings. At eight, a £410 meeting makes a £3,280 client and a £1,200 meeting makes a £9,600 client.

How do I calculate my agency's client acquisition cost?

Take everything you spent on new business last quarter, including ads, the hire, the deck and the senior hours in pitches. Divide it by the first meetings that actually happened, then by the clients you won. Most agencies that do this find the biggest cost is senior time in pitches they were never going to win.

How much does a new business hire cost an agency?

About £4,100 a month on the Indeed UK average BDM salary of £42,625, with employer NI and pension. The Bridge Group puts ramp at about three months, so the first quarter costs £12,000 and produces very little. From month four it works out at about £410 a meeting, with median attrition of around 40% a year.

What a new client really costs a marketing agency

Most agencies know their average retainer. Almost none know what the first meeting with a new client cost them. Four ways of getting it, costed, and the number to put in your own spreadsheet.

Part of Lead generation for marketing agencies →

An agency owner who can tell you their average retainer to the pound will usually have no idea what it costs them to get a first meeting with a new client. Which is odd, because the second number decides whether the first one is any good.

Here it is, worked out four ways, with the sources underneath. Then the two multiplications that turn it into your acquisition cost.

Option one: referrals

Free, apparently. In practice the cost is the time spent keeping a network warm and the revenue lost in the months nobody refers. RSW/US found three in four agencies call referrals their primary source. Nobody has costed waiting.

Option two: paid ads

Agency terms are among the most expensive in Google Ads, because every agency bids on them. WordStream's 2025 benchmarks for business services put a form fill at £100 to £150 at the upper end. Most form fills from agency ads are students, suppliers and people shopping around.

At 10 to 20% of leads becoming a real conversation, with a 15 to 20% management fee on top, a meeting with an actual marketing director costs £500 to £1,200. And the phone stops the day the budget does.

Option three: a new business hire

The Indeed UK average salary for a business development manager is £42,625. With employer National Insurance and pension, roughly £4,100 a month before commission, data or a phone.

The Bridge Group's 2025 benchmark puts ramp at about three months and the median at ten held meetings a month once ramped. So about £410 a meeting from month four, and a first quarter that costs £12,000 and produces very little. Median attrition in the same report is around 40% a year.

Option four: outbound in your voice, run for you

A list rebuilt weekly from the brands showing a buying signal. Messages in the founder's voice on LinkedIn, carried to email and text. A British caller who rings every interested reply within 24 hours. On one LinkedIn seat at three to five qualified meetings a month, that models at £98 to £197 a qualified meeting. A model, not a promise: your market and your offer decide the result.

Our own campaign, which we ran on ourselves before any client, reached 5,950 people over three months, started 752 conversations and booked 65 meetings. We are an agency too. We priced this on our own numbers.

The two multiplications

Cost per meeting is not acquisition cost. Two more numbers get you there.

Meetings to client. How many first meetings does it take to win one retainer? For most agencies it is somewhere between four and eight. If it is eight, a £410 meeting is a £3,280 client and a £1,200 meeting is a £9,600 client.

Client value. Monthly retainer times the months a client stays. AgencyAnalytics' 2026 report found industry expertise is the single biggest factor in winning new business, named by 59% of agency leaders, and specialist agencies tend to keep clients longer. If your average client is £4,000 a month for 18 months, that is £72,000. Against that, the difference between a £400 meeting and a £150 meeting is not the point. The point is whether you are getting meetings at all, every month, including the months you are busy.

Work out your own number

Take everything you spent on new business last quarter: ads, the hire, the deck, the senior hours in pitches. Divide by first meetings that actually happened. Then divide by the clients you won. Most agencies that do this for the first time find that the real cost is not the ads or the hire. It is the senior time in pitches they were never going to win, which is why being in before the brief matters more than pitching better.

Then decide

If your number is under £200 a meeting and the diary is full, keep doing what you are doing. If it is £500 and up, or if the honest answer is "we do not get meetings in busy months", that is the gap lead generation for marketing agencies fills.

Book a 1-to-1. Bring your average retainer and your meetings last quarter, and we run your numbers live.
