Calculate with explicit assumptions
Coding-agent costs are easy to underestimate because a single user task may trigger many model requests. Large input contexts, retries, evaluator passes, and tool-result summaries accumulate across a session. Prompt caching can materially change the total, so the estimator separates cached and uncached input before projecting daily, monthly, and annual spend.
Review model pricing before committing budget
Provider prices, cache rules, batch discounts, context tiers, and regional availability can change. Treat the result as a planning estimate, verify the selected rates against the current provider documentation, and use custom pricing when your contract differs from the public list price.
