Short answer: Marketing contribution to pipeline is the share of your open sales opportunities, by value, that marketing created or helped create. It is usually reported two ways: marketing sourced pipeline, where marketing produced the first contact, and marketing influenced pipeline, where marketing touched the deal at some point. There is no correct percentage. The right share depends on what you sell, who you sell to, and how your company splits the work between marketing and sales.
- Sourced: marketing created the opportunity.
- Influenced: marketing touched an opportunity someone else created.
- The trap: comparing your share with another company’s without comparing definitions.
This guide contains no benchmark percentages. We looked for one with a named study, a sample and a year behind it, and did not find one we could verify, so we have explained what drives the number instead.
What does marketing contribution to pipeline mean?
Your pipeline is the total value of deals your sales team is currently working. Marketing contribution asks a simple question about that total: how much of it exists because of marketing?
The question matters because marketing spends money long before revenue shows up. Counting leads rewards volume, and counting closed revenue takes months to report. Pipeline sits in the middle. It shows whether marketing is producing real sales conversations, soon enough to act on.
Two versions of the measure are in common use, and they give very different numbers.
| Measure | What counts | Weakness |
|---|---|---|
| Marketing sourced pipeline | Deals whose first contact came from marketing | Ignores later help |
| Marketing influenced pipeline | Deals with any marketing touch | Can count nearly everything |
Sourced is strict. If a prospect read your articles for a year and then replied to a salesperson’s email, sourced credit goes to sales. Influenced is generous. If a prospect who was already in talks opened one newsletter, the whole deal can count as influenced. Most companies that report on this track both and keep them apart.
How is marketing sourced pipeline measured?
The formula is short. Add up the value of opportunities created in a period where marketing was the source. Divide by the value of all opportunities created in that period. The work is in agreeing what the words mean. Four decisions set the number:
- What counts as an opportunity. Marketing contribution only makes sense if a deal enters the pipeline by a written rule. See our guide to B2B sales pipeline stages.
- Which sources belong to marketing. Website forms, events and content are usually marketing. Referrals, partner introductions and outbound prospecting are where companies disagree.
- Which touch gets the credit. First touch credits whatever started the relationship. Last touch credits whatever came right before the opportunity. Multi-touch models split the credit. Each is defensible and each gives a different answer.
- How far back you look. A buyer who downloaded a guide two years ago and came back through a referral last week could be either. Pick a window and keep it.
None of these has a right answer. What matters is that the rules are written down, sales and marketing both accept them, and they stay the same from quarter to quarter. A number that moves because the definition moved tells you nothing.
It also depends on clean source data. If salespeople create opportunities without recording where the lead came from, the gaps tend to be counted as sales sourced by default, and marketing’s share is understated.
How much should marketing contribute to sales pipeline?
People search for how much marketing should contribute to sales pipeline hoping for one percentage. You will find percentages quoted online. The ones we checked either named no study or pointed to a roundup that named none, so we are not repeating them. Even a well sourced figure would be an average across companies that define “sourced” differently.
What you can reason about is which direction your own share should lean:
| Factor | Marketing share tends higher | Tends lower |
|---|---|---|
| Deal size | Small, frequent deals | Large, rare deals |
| Number of possible buyers | Thousands | A named list |
| Buyer awareness | Buyers search for it | Buyers do not know it exists |
| Who owns outbound | Marketing | Sales |
| Existing customers | New business focus | Growth from renewals and referrals |
A company selling a low-priced product to a huge market, where buyers search for a solution, should expect marketing to source most of its pipeline. A company selling a six-figure service to two hundred known accounts will get most of its pipeline from salespeople and referrals, and that is healthy.
So set the target from your own plan. Start with the pipeline you need to hit revenue, subtract what sales, referrals and existing customers reliably produce, and the remainder is what marketing has to source. Our page on sales pipeline conversion rates shows how to work out the total pipeline you need.
Where does outbound sit between sales and marketing?
Outbound is the line item that most often changes a company’s marketing contribution without anything real changing. Cold email, cold calls and direct messages to people who have not asked to hear from you can sit in either department.
- Under sales. Sales development reps report to a sales leader, and the opportunities they create count as sales sourced.
- Under marketing. The same reps report to marketing because they work the same lists and messages as campaigns, and their opportunities count as marketing sourced.
- Outside both. An agency or outsourced SDR team runs it, and someone has to decide which column it lands in.
Move outbound from one department to the other and marketing’s share of pipeline can swing sharply overnight. This is another reason cross-company comparisons mislead.
The practical fix is to report outbound as its own source: inbound marketing, outbound, referrals and partners, and existing customers. Then the argument over who gets credit matters less, and you can see what each channel costs and produces. Our guides to inbound vs outbound lead generation and B2B marketing channels compare how the channels behave.
How do you count pipeline from an outside provider?
The same way as any other source, with its own label. Before the first campaign, agree on three things: what the provider hands over (a reply, a qualified reply or a booked meeting), at what point that becomes an opportunity in your CRM, and who records it. Tag every one of those deals with the provider as the source.
Then compare the pipeline value from that source with what you pay for it, over a period long enough to cover your sales cycle. The outbound ROI calculator does that sum with your own numbers.
For clarity on what we cover: Next Reply does cold email only. We do not run paid ads, SEO, LinkedIn outreach or cold calling, and we do not manage your CRM or attribution. We build the list, send and follow up, and report monthly on what came back. Whether that pipeline is labelled sales or marketing in your reports is your call.

Frequently asked questions
What is marketing contribution?
Marketing contribution is the share of pipeline or revenue that can be credited to marketing activity. It is reported as marketing sourced, marketing influenced, or both.
What is the difference between marketing sourced and marketing influenced pipeline?
Sourced means marketing created the first contact that led to the opportunity. Influenced means marketing had at least one touch with a deal, whoever created it. Influenced is always the larger number.
Is there a benchmark for marketing sourced pipeline?
Figures circulate, but we could not trace one to a study with a disclosed sample, and definitions vary too much between companies for a single figure to be useful. Set your target from your own revenue plan.
Does outbound count as marketing sourced pipeline?
It depends on who owns it at your company. Some count it under sales, some under marketing. Reporting outbound as its own source avoids the argument and makes the cost easier to judge.
Should marketing be measured on pipeline or on leads?
Pipeline is the harder test, because a lead only counts once sales accepts it as a real opportunity. Lead counts are still useful as an early signal, as long as nobody treats them as the goal.
