Price your AI feature with a healthy margin over its API cost.
Traditional SaaS has near-zero marginal cost; AI features don't. A heavy user can erase your margin. Cap usage, tier pricing, or meter it. Model the underlying cost on the AI app cost estimator.
Free AI SaaS margin calculator — your AI cost per user and target margin to the price you should charge.
Price = total cost per user ÷ (1 − target margin). Include the AI API cost plus your other per-user costs, then mark up to your desired gross margin. Usage-based AI cost makes this trickier than fixed-cost SaaS.
Because your cost per user is variable — a power user can burn far more tokens than a light one. Flat pricing on variable AI cost can turn your best customers into loss-makers unless you cap or tier.
