CAC, LTV & SaaS Growth Calculators for US Businesses
Currency-aware calculators in USD ($) for United States businesses. Model your customer acquisition cost, lifetime value, ROAS, and more — with example scenarios in your local currency.
The United States remains the largest SaaS market globally, with venture-backed startups and scaled companies alike competing on unit economics. Founders pricing in $ need to track customer acquisition cost alongside lifetime value to benchmark against well-funded competitors. High ad-spend markets like Google and Meta in the US mean CAC discipline is critical from seed stage onward.
American SaaS buyers expect transparent, self-serve pricing — which makes metrics like MRR, ARR, and NRR essential for tracking subscription health. Whether you are bootstrapping in Austin or raising a Series B in San Francisco, understanding your LTV:CAC ratio in real dollar terms tells investors (and yourself) whether growth is sustainable.
These calculators let you model scenarios in USD so you can compare your numbers directly against US-market benchmarks, plan budgets in familiar dollar amounts, and present investor-ready metrics without manual currency conversion.
Example Scenarios in USD
These are illustrative examples using realistic numbers in USD — not benchmarks. Use the calculators below with your own data.
- A DTC SaaS startup spending $50,000/month on paid search to acquire 100 customers has a CAC of $500. If monthly ARPU is $120 at 78% margin with 3% churn, LTV comes to roughly $3,120 — a 6.2:1 LTV:CAC ratio.
- An e-commerce brand running $20,000 in Meta ads that drives $88,000 in revenue achieves a 4.4:1 ROAS. With 45% gross margin, break-even ROAS is 2.2:1, so the campaign is profitable.
- A mid-market SaaS at $2M ARR with $80K net new ARR last quarter on $65K S&M spend has a Magic Number of 1.23 — signaling efficient growth worth scaling.
