Serverless Function Cost Calculator

Lambda bills requests plus GB-seconds of compute. The defaults price 100 million requests at 200 ms and 512 MB, which lands at $179.80 a month after the free tier. Compute is about 89 percent of that, so memory and duration decide the bill.

Every result is pre-rendered with the default inputs, so the numbers are readable with JavaScript off. Results update as you type and nothing leaves your browser. Part of the Buildopsy engineering calculators.

Price a function from request volume, duration and memory, then apply the monthly free tier of one million requests plus 400,000 GB-seconds.
