Attribution Spend-Waste Finder
Calculate the share of your marketing spend going to channels you can't attribute properly — and how much you could reallocate to top-performing channels by improving attribution accuracy.
Total monthly across paid channels, content, and outbound
Most B2B teams sit at 50-70% (Forrester 2024)
Typical recoverable after better attribution: 20-30%
Estimated annual marketing spend on under-attributed channels you could reallocate
$24,000
At 60% attribution accuracy, roughly $120,000 of your annual spend goes to channels you can't measure properly. Better attribution typically lets teams reallocate 20% of that to top-performing channels.

How to Use This Calculator
The calculator starts from your monthly marketing spend, then applies your current attribution accuracy to estimate how much spend is going to channels you can't measure properly. It then applies a recoverable percentage (typically 20-30%) to show what could be reallocated to top performers after attribution improves.
Most B2B teams sit at 50-70% attribution accuracy (Forrester 2024) — meaning 30-50% of spend is going to channels with unclear performance. 40-60% of B2B buying influence happens in dark-social channels untracked by most setups (Demandbase 2024). Better attribution typically lets teams reallocate 20-30% of mis-attributed spend without changing the total budget.
Frequently Asked Questions
What's "attribution accuracy" exactly?
The percentage of your marketing spend you can confidently tie to revenue or pipeline outcomes. A team running pure last-click attribution on UTM-tagged channels has high accuracy on those channels but 0% accuracy on dark-social, referral, and word-of-mouth — so their overall accuracy is often 40-60%.
How do I estimate my current attribution accuracy?
Take the share of revenue your attribution model can confidently source to a specific channel. If 60% of closed-won deals have a clear first-touch channel in your dashboard, you're at ~60% accuracy. The rest is mis-attributed or unattributed.
Why is 20-30% the recoverable share?
Most teams have meaningful but recoverable waste — channels that look like they're working but actually aren't (over-credited because of last-touch bias), and channels that look weak but actually drive influence (under-credited because they touch buyers early in dark channels). Better attribution usually recovers 20-30% of waste; above that requires structural changes.
What about Apple Mail Privacy Protection and iOS 14.5?
Real concern. ATT dropped paid-social attribution accuracy 30-50% (AppsFlyer 2023). Modern attribution tools compensate via server-side tracking, first-party data, and marketing-mix modeling. AMW Attribution uses all three to maintain accuracy under privacy constraints.
What's "dark-social" / "dark-funnel"?
Marketing influence happening in untracked channels — Slack DMs, WhatsApp groups, podcasts, conferences, word-of-mouth. Estimated 40-60% of B2B buying influence happens here. Modern attribution attempts to surface these signals through buyer surveys, self-reported source fields, and predictive modeling.
Does this require switching attribution platforms?
Often yes — basic UTM-based dashboards can't handle the dark-funnel and multi-touch math required for meaningful recovery. AMW Attribution is built into AMW Suite and handles this natively. Talk to us for a setup that matches your current channel mix.
