Note: This checks token economics only. It does not account for infrastructure, support, retries, refunds, chargebacks, or other overhead. Treat SAFE as a necessary-but-not-sufficient condition for profitability.

Frequently asked questions
How do I price token usage for my AI SaaS?
Compute your blended cost per 1M tokens from your input/output mix, then set a plan price whose net revenue (after Stripe/platform fees) covers the included quota with at least 15% margin. Overage should be 1.6x or more above blended cost. The calculator above does all of this instantly.
What blended cost should I use for an AI SaaS in 2026?
At a typical 4:1 input:output ratio: budget models (Flash/Lite tiers) ~$0.40/1M tokens, smart mid-route ~$1.00/1M, Sonnet-tier ~$3.60/1M, flagship Opus-tier ~$9.00+/1M. Use the calculator's input fields to match your actual routing mix.
Why do AI SaaS plans lose money even with usage caps?
Three common reasons: (1) blended cost is higher than assumed because users route to the most expensive model, (2) overage price is below blended cost so heavy users cost you more than they pay, (3) payment fees (Stripe ~2.9% + 30¢) and platform fees eat margin on low-priced plans. The calculator flags each.
How much can I safely include in a $19/month AI plan?
At a $0.40/1M blended cost (budget routing), a $19 plan nets ~$18.14 after payment fees and can safely include ~45M tokens with 15% margin. At $3.60/1M (Sonnet-tier), the same plan only fits ~1.5M tokens safely — that's a 30x difference.
