Turn marketing spend into clear acquisition insights. Choose your industry, model, and primary channel first. Get benchmark status, payback estimate, and improvement tips instantly.
Use consistent attribution rules across periods. Include only costs that directly support acquisition for the selected period.
Use this as a template for tracking periods and comparing performance.
| Period | Marketing | Sales | Total acquisition cost | New customers | CAC | Primary channel |
|---|---|---|---|---|---|---|
| Jan | $11,200 | $5,800 | $18,900 | 38 | $497.37 | Paid Search |
| Feb | $12,000 | $6,000 | $20,000 | 40 | $500.00 | Mixed |
| Mar | $10,500 | $5,200 | $17,300 | 44 | $393.18 | SEO (Organic) |
Track acquisition costs by the same period as new customers. In many teams, paid media and sales labor represent most spend, while tooling and agency fees add a smaller but persistent layer. This calculator separates marketing, sales, contractors, and software so you can see which bucket drives changes. A 10% spend rise with flat customers increases CAC by 10%.
Benchmarks vary by model, price point, and buying friction. B2B motions often carry higher CAC because of longer cycles and salesperson time, while ecommerce can be lower but sensitive to seasonality. The built‑in ranges here are adjusted with channel multipliers because outbound and paid social frequently cost more than referrals or lifecycle email. Use custom ranges when your segment is niche.
As you scale budgets, the same channel typically gets less efficient. Higher frequency raises costs, and broader targeting lowers conversion. Compare your CAC to the benchmark midpoint, then watch funnel metrics like cost per lead and lead‑to‑customer rate. If CAC rises while CPL stays stable, your conversion is likely slipping. If CPL rises first, your targeting or auction competitiveness may be changing.
CAC is only healthy when margin and retention support it. The calculator estimates LTV using ARPA, gross margin, and lifespan months, then derives payback months from monthly gross profit. For subscription businesses, many operators aim for a payback under 12 months and an LTV:CAC ratio above 3. If payback is long, focus on activation, onboarding, and early expansion revenue.
Always use the same attribution window and conversion definition across periods. Mixing first‑touch and multi‑touch reporting will distort trend lines. If you enter attributed conversions, you can compute a comparable CPA alongside CAC, which helps isolate attribution shifts. Keep promotions and discounts in the cost base when they are required to win the customer, otherwise CAC will look artificially low.
Run the calculator for each month and export the CSV for reporting. Sort by status, then list the top drivers: spend changes, customer volume changes, and conversion changes. Use the chart to communicate where you
Include costs that directly generate new customers in the selected period: ads, sales outreach, agencies, and required tools. Exclude long‑term brand initiatives unless they are measured as acquisition drivers for the same period.
High CAC is usually caused by weak conversion rates, expensive traffic, or a longer sales cycle. Check cost per lead, lead‑to‑customer rate, and payback months. Then test tighter targeting, stronger offers, and better landing pages.
Yes. Use the custom benchmark option to enter a range that matches your geography, pricing tier, or audience. Keep the range stable over time so your monthly comparisons remain meaningful.
It is a simplified model using ARPA, gross margin, and average lifespan months. It is useful for quick comparisons and planning, but you should replace it with cohort retention and expansion analysis when available.
Targets vary by business model and cash constraints. Many subscription teams aim for payback under 12 months, while fast‑moving ecommerce may target much shorter windows. Use your gross margin and retention reality to set the threshold.
Use the same attribution rules, include the same cost categories, and match the time window for spend and customers. Export CSV monthly and review trends in CAC, conversion rates, and benchmark status together.
