Calculate CAC from sales and marketing spend and the number of new customers won.
CAC = Acquisition spend ÷ New customers.
Spend 90,000 and 120 new customers. CAC = 750.
Blended CAC divides all sales and marketing cost by all new customers, including organic. Paid CAC uses only paid spend and paid-attributed new customers. Both are useful. Do not mix them in one chart.
A 750 CAC is cheap if contribution LTV is 3,000 and slow-pay if LTV is 800. Use the LTV calculator next and compare LTV:CAC, not CAC in isolation.

Use any currency as long as every input uses the same one. The math does not depend on a currency code.
CAC = Spend ÷ New customers.
Estimate simple LTV from AOV, purchase frequency and gross margin.
Calculate return on ad spend from attributed revenue and ad cost.
Calculate return on investment from net profit and the amount invested.
Define the store metrics that matter, run a simple reporting cadence, stay humble about attribution, and connect numbers to decisions — not to dashboards for their own sake.
Improve store conversion with research, hypotheses and honest changes to product pages, cart, checkout, trust and shipping promises — without dark patterns.
CAC is what you spend to win a customer. Blended and paid CAC answer different questions. This article lists what belongs in that spend—and what does not.
LTV estimates future contribution from a customer. Simple averages hide cohorts. Use a contribution model and treat precision as a range, not a forecast.
ROAS measures media efficiency. ROI measures return after costs. Use this comparison to pick the right question for ads, margin and contribution profit.
ROAS is ad revenue divided by ad spend. Useful for media, incomplete for profit. Learn the formula, break-even ROAS from margin, and attribution limits.
