How The Calculator Works (Simple Math, Serious Clarity)

  1. We turn your goal into a monthly target. Annual Revenue Goal ÷ 12 = Monthly Revenue Target (if you choose annual).
  2. We divide by your ROAS to get your ad budget. Monthly Revenue Target ÷ ROAS = Required Monthly Ad Spend.
  3. We use Offer Price and CPA (if provided) to model customers. Monthly Revenue Target ÷ Offer Price = Orders/Clients Needed. Monthly Ad Spend ÷ CPA = Customers You Can Acquire.

No hacks. No hype. Just the same math top advertisers use to plan profitable growth.

Who Should Use This Calculator

  • Service businesses doing $1M–$10M+ who want a predictable growth plan.
  • Founders tired of guessing ad budgets every month.
  • Teams who need to justify ad spend to leadership or investors.
  • Business owners who want to scale to $1M, $5M, or $10M in paid-driven revenue with confidence.

What’s A “Good” ROAS For Your Business?

Every industry is different, but here’s a simple rule of thumb:

  • 2–3 ROAS: Early stage or higher-cost industries.
  • 4–7 ROAS: Strong offer, dialed-in funnel, solid creative.
  • 8–10+ ROAS: World-class execution and/or high margins.

If your current ROAS is below target, you don’t necessarily need to spend less. You need better strategy, better offers, and better creative.
