Key takeaways

• Track CAC variants separately: blended, paid-only, and incremental for better budget decisions.

• Calculate CAC by cohort and channel, adjust for refunds and chargebacks, then tie targets to LTV and payback.

• Fix measurement first, then reduce CAC with creative systems, funnels, affiliates, and offer design.

• Use a 90-day plan and weekly governance to keep CAC trending down without hurting volume.

Define CAC scope for prop firms

Define CAC once, document it, and keep it consistent across reporting so your decisions are comparable month to month and market to market.

• Checklist: what to include in CAC

  • Media spend and platform fees (for example Google Ads, Meta Ads, TikTok Ads)

  • Agency or contractor fees for ads, creative, and CRO

  • Creative production costs tied to acquisition campaigns

  • Affiliate and influencer commissions, and network/platform fees (for example Impact, PartnerStack, Tapfiliate)

  • Tracking, analytics, and landing page tool costs proportionally allocated to acquisition (for example Google Analytics 4, Mixpanel)

  • Discounts or promo credits used solely to acquire first-time customers (treat as CAC or as revenue reduction, but document and apply consistently)

  • Refunds, chargebacks, and payment processor fees tied to the first purchase

• What to exclude or track separately

  • General brand PR and community management without acquisition intent

  • Product development, payout operations, and support not directly tied to acquisition

  • Ongoing retention or reactivation campaigns for existing customers

• Definitions for prop firms

  • Customer definition: a first-time paid evaluation purchaser

  • Acquisition window: 7 to 30 days post-click or post-view per policy, chosen once and documented

  • Geography and product line separation: track CAC per market and per evaluation tier, as the mix drives both cost and LTV

Build your CAC data foundation

Before optimizing, ensure you can trust your numbers and reconcile spend to customers and revenue.

• Tracking stack recommendations

  • Web and app analytics: Google Analytics 4, Mixpanel

  • Tag orchestration: Google Tag Manager, and consider server-side tagging

  • Attribution and link tracking: platform pixels in Google Ads, Meta Ads, TikTok Ads, and trackers like RedTrack or Voluum if you run affiliates or multi-geo

  • Affiliate platforms: Impact, PartnerStack, Tapfiliate

  • Mobile and cross-channel attribution at scale: Adjust, AppsFlyer

  • CRM and revenue: HubSpot, Salesforce

  • Reporting: Looker Studio

• Data model principles

  • A single unique customer ID across analytics, CRM, checkout, and affiliate systems

  • Cohort by first purchase month and market (for example, US-Apr-2026)

  • Channel and campaign naming conventions that encode geo, funnel stage, product tier, and creative angle

  • Monthly cost ingestion and reconciliation to platform invoices and bank debits

• Measurement checklist

  • First-purchase events capture the revenue amount, coupon code, and refund or chargeback flags

  • Persist UTMs and affiliate IDs through checkout and into CRM

  • QA attribution links and pixels weekly, including test orders

  • Run daily cost and conversion sanity reports to catch anomalies early

The CAC formula matrix with examples

Standardize your formulas so teams speak the same language when planning and reviewing.

• Core definitions

  • Paid CAC = total paid acquisition costs in the period divided by number of new customers in the period

  • Blended CAC = all acquisition costs (paid and organic content, affiliate, platform tools allocated) divided by all new customers

  • Incremental CAC = change in cost divided by change in new customers versus a control or prior period, useful for budget increments

• Adjustments

  • Net CAC after refunds and chargebacks (remove refunded customers from the denominator, include payment processing and chargeback fees in costs)

  • CAC by cohort, by market, and by evaluation tier, because mix shifts can mask problems

• Worked examples with clear assumptions

  • Example A: Paid Social US, April

    • Spend 80,000; new customers 1,000; gross paid CAC = 80.

    • Refunds 8 percent on an evaluation fee of 100, so 80 refunds. Processor fee 3 percent on charge volume (100 x 1,000 x 3 percent = 3,000).

    • Net customers = 1,000 minus 80 = 920. Adjusted cost = 80,000 plus 3,000 = 83,000.

    • Net CAC = 83,000 divided by 920 = 90.22.

  • Example B: Affiliates EU

    • Commission 25 percent per first purchase of 200, so 50 per customer. 400 customers, platform fee 5 percent of commission = 2.50 per customer.

    • CAC per customer = 50 plus 2.50 = 52.50. Total cost = 52.50 x 400 = 21,000.

• Monthly cohort CAC example

Numbers above are illustrative. Use your own cohorts and actual processor and refund data.

Attribution choices and channel CAC

Choose the simplest attribution model that gives you stable directional insights, then layer complexity as you scale.

• Model options overview

  • Last non-direct click, easy to implement and aligns to analytics tools

  • Position-based, credits first and last touch more heavily

  • Data-driven attribution within platforms, good for optimizing in-channel

  • Multi-touch models in analytics tools for cross-channel visibility

  • Media mix modeling for larger spend levels and longer cycles

• Pitfalls and guardrails

  • Double-counting across walled gardens when you sum platform reports

  • View-through inflation on display and social without strict windows

  • Affiliate and paid social overlap, use de-duplication and clear rules

• Attribution models comparison

Baseline and diagnostics in 14 days

Create a current CAC baseline and isolate the biggest leaks before rebuilding your stack.

• Day 1 to 3

  • Confirm definitions and inclusion rules, QA pixels and conversions, align naming conventions

• Day 4 to 7

  • Pull last 90 days by channel and market, compute paid, blended, and net CAC

• Day 8 to 10

  • Break down the funnel: click to landing page, landing page to checkout, checkout to purchase

  • Identify the top three drop-offs by absolute lost customers and by rate

• Day 11 to 14

  • Prioritize five fixes by impact and effort, define owners and deadlines

Example baseline snapshot

• US Paid Social: CAC 95, landing page CVR 2.0 percent, LCP 4.5 seconds

• DE Affiliates: CAC 62, average commission 22 percent, refund 5.5 percent

Targets: LTV, payback and risk guardrails

Tie CAC targets to realistic LTV, payback periods, and your risk tolerance, not just channel averages.

• Define LTV for prop firms

  • Components: evaluation revenue net of refunds, repeat evaluations, funded account fee revenue where applicable, performance fee share from profitable traders over a defined horizon, minus payment and payout costs

• Payback and caps

  • Target payback period on a contribution basis (for example within 2 to 3 months on core markets)

  • Set CAC to LTV thresholds by market risk and cash flow needs (for example CAC no more than 35 to 45 percent of expected LTV on base assumptions)

• Scenario planning (illustrative)

  • Inputs: average evaluation fee 200, pass rate 8 percent, average repeat evaluations 1.4 per customer over 6 months, net performance fee contribution per funded trader 350 over 6 months, payment costs 3 percent on purchases, refund rate 7 percent.

• Unit economics scenarios

Replace with your own data, and revisit targets at least quarterly. Numbers above are examples, not benchmarks.

Quick wins to reduce CAC in 30 days

Channel playbooks to drive down CAC

Use repeatable, standards-based setups to avoid constant reinvention and to scale learnings across markets.

Paid social: Meta, TikTok, YouTube

Balance reach and control with simple structures and a creative engine.

• Structure checklist

  • Separate prospecting and retargeting with clear budgets

  • Use broad and interest stacks to test scale, and keep geos and tiers separated

  • Creative taxonomy by angle (rules clarity, payouts, platform UX) and format (UGC, motion, static)

• Creative system

  • Angles: platform walkthroughs, rule summaries, trader interviews with compliant framing

  • Weekly creative scorecard tracking thumbstop, CTR, and landing page CVR

• Bidding and measurement

  • Optimize to the purchase event on 7-day click attribution

  • Monitor blended CAC vs platform-reported CPA to avoid over-crediting

• Example numbers

  • Goal CTR above 1.2 percent, landing page CVR above 3.0 percent, target CAC under 85 for a US tier example

Paid search: Google and Bing

Capture active intent, and police waste relentlessly.

• Structure checklist

  • Separate brand, competitor, and non-brand themes with distinct budgets

  • Use tight theming for high-intent terms and SKAG-like groupings where volume allows

• Negative keywords and exclusions

  • Exclude coupon, free, crack, torrent terms to prevent affiliate cannibalization and low-quality clicks

• Ads and extensions

  • Compliance-safe copy with sitelinks to program rules, payout timelines, and FAQs

• Example metrics

  • Brand CPC under 0.60 example, non-brand CVR above 4 percent example with strong landing pages

Affiliates and influencers

Design partner economics and controls to keep CAC predictable and fraud low.

• Program design

  • Define new-customer attribution, cookie window, and last-click rules that de-duplicate against paid search

  • Commission tiers with LTV-based caps, plus clawbacks for refunds and chargebacks inside 30 days

• Compliance and fraud checks

  • Disallow trademark bidding, forced clicks, incentivized traffic

  • Manual review and sandbox testing for high-velocity partners

• Sample affiliate commission tiers

Organic search, content and PR

Build compounding, lower-cost demand that reduces blended CAC over time.

• Content roadmap

  • Evaluation model explainers, funding rules, payout timelines, and firm comparisons using neutral, factual language

• Technical SEO

  • Page speed, structured data, and internal linking hubs to rules and pricing

• Digital PR

  • Thought leadership on risk management, payouts, and trader education initiatives that attract links and press mentions

Partnerships and communities

Meet prospects in trusted spaces and make attribution clean.

• Work with trading educators, Discord communities, newsletters, and webinars

• Use unique codes and UTMs, pay per new customer, and retarget post-event attendees with tailored LPs

Funnel and onsite conversion improvements

Improving conversion rate reduces CAC without raising bids, since your cost per click buys more customers.

• Speed and UX checklist

  • Target LCP under 2.5 seconds and CLS under 0.1, and simplify pricing blocks and rule summaries

• Social proof and clarity

  • Payout timelines, rule summaries, Trustpilot review counts, and calculator widgets for account size and fees

• Checkout optimization

  • Short forms, guest checkout, and local payment methods increase completion rates

• Example math

  • If paid CAC is 100 at a 2 percent CVR, increasing CVR to 3 percent with the same CPC reduces CAC to about 67

International and localization effects on CAC

Local market economics can change CAC materially. Validate before scaling spend.

• Market selection

  • Assess CPMs and CPCs, language coverage, local regulations, and payment rails and acceptance

• Localization checklist

  • Native-language landing pages, localized proof points and examples, local currency and payment methods

• Example decision gate

  • Require CAC within 15 percent of your target for two consecutive weeks and refund rates within guardrails before scaling budget

Compliance, fraud and policy risk

Staying compliant reduces CAC volatility, ad account risk, and refund-driven net CAC creep.

• Ad policy

  • Follow platform rules on earnings claims and financial promotion policies, and use balanced risk language and disclosures

• Fraud controls

  • Implement velocity checks, VPN detection, device and card fingerprinting, and affiliate click-injection monitoring

• Chargeback mitigation

  • Clear refund terms, pre-purchase confirmations of program rules, 3DS where supported by your payment processor

FAQ

Addressing common questions we hear from prop firm founders and operators.

What is a good CAC for a prop firm?

A good CAC is one that fits your LTV and payback constraints by market and tier. Many firms target CAC at or below 35 to 45 percent of realistic 6-month LTV with a 60 to 90 day payback on a contribution basis, but you should set targets using your cohorts, refund rates, and performance fee contribution rather than generic benchmarks.

Should refunds, chargebacks and payment fees be included in CAC?

Yes, include direct costs tied to acquiring a first-time customer, including processor fees and chargeback fees. For refunds, remove refunded first-time purchases from the new customer count to calculate net CAC and track the refund rate by channel to avoid scaling traffic that erodes margins.

How often should we recalculate CAC targets and review attribution?

Revisit CAC targets quarterly and after major offer or pricing changes. Review attribution models when you add new channels, scale budgets materially, or see divergence between platform-reported CPA and blended CAC that persists for two or more weeks.

What CAC payback period is reasonable in this category?

Most firms we see aim for a contribution payback within 60 to 90 days on core markets, with longer allowances for new geos or channels during testing. Shorter payback reduces cash risk but can limit scale, so align it with your capital availability and LTV confidence.

How do we avoid double-counting between affiliates and paid ads?

Set last-click attribution rules across paid search and affiliate, use de-duplication in your affiliate network, and suppress branded search and coupon terms for partners. Require partners to disclose traffic sources and block trademark bidding and forced clicks.

How should we structure affiliate commissions to keep CAC predictable?

Use tiered CPA caps tied to your LTV guardrails and apply clawbacks for refunds and chargebacks within a defined window. Pay uplifts for premium placements after quality is proven, not in advance, and require unique UTMs or coupon codes for tracking.

Which attribution model is most practical for a firm under 5 million in annual ad spend?

Last non-direct click in GA4 plus platform optimization to the purchase event is usually sufficient, supplemented by a blended CAC view for sanity. As you add channels and scale, consider position-based or a lightweight multi-touch tool once taxonomy and data hygiene are in place.

How do we factor repeat evaluations into LTV and CAC targets?

Model repeat evaluations as additional purchase events per customer over a fixed horizon, net of refunds and payment fees. Recompute cohort LTV quarterly using actual repeat rates and adjust CAC targets and affiliate caps accordingly.
