Frequently asked questions
What is gross margin for an AI agent SaaS?
Gross margin is monthly revenue minus the direct variable costs of serving each user. For AI agent products, those direct costs usually include LLM/API calls, hosting/compute, vector storage, customer support, payment processing, and other per-user COGS.
Should I include LLM API costs in gross margin?
Yes. LLM API spend is typically the largest variable cost for an AI agent product and should be included in cost of goods sold (COGS), not operating expenses.
What is a healthy gross margin for a SaaS or AI agent business?
Most SaaS businesses target 70–80%+ gross margins. AI agent products often start lower because of API costs; anything above 60% is usually acceptable to investors, while below 40% signals a need to raise prices or reduce per-user costs.
How do payment processing fees affect margin?
Payment processors typically charge a percentage plus a fixed fee per transaction. For low ARPU products, the fixed fee can be meaningful, so this calculator includes both components.
How do I improve gross margin per user?
Raise prices, switch to cheaper models or local inference, reduce context length, cache prompts, lower support cost through better self-serve, or negotiate lower payment processing rates at scale.
Gross margin here is revenue minus direct variable costs (LLM/API, hosting, support, payments, and other COGS). It excludes fixed R&D, sales, and G&A. Use this calculator to set pricing and target margins before scaling paid acquisition.
