Built for engineers who hate surprise invoices.

APICalculators is a free, privacy-first hub of cost calculators for modern developer infrastructure — from LLM tokens to payment-processor fees.

Why we built this

Cloud and AI pricing pages are a maze of per-million-token rates, read units, pod-hours, and percentage fees. A "cheap" model can quietly become a four-figure monthly bill at scale. We wanted one fast place to sanity-check the numbers before shipping to production — without spreadsheets, signups, or sending data anywhere.

Our methodology

Every calculator uses published, public pay-as-you-go pricing, which we review monthly. Where providers price on complex dimensions, we use transparent simplified models and clearly label them as estimates. We'd rather give you an honest order-of-magnitude number than a falsely precise one.

How we stay free

The site is supported by display ads and affiliate partnerships with infrastructure providers we'd recommend anyway. Affiliate links are always marked, and they never change the math in the calculators.
