About InkPrices
What is this?
InkPrices is a free, no-frills comparison tool that ranks printer ink cartridges and toner by cost per page — the only metric that actually matters when choosing consumables. Inspired by diskprices.com.
Where does the data come from?
Prices and product details are sourced from the Amazon Product Advertising API (PA-API 5.0). Page-yield figures are parsed from manufacturer-published ISO yield ratings embedded in product titles and descriptions (ISO/IEC 24711 for inkjet, ISO/IEC 19752 / 19798 for laser). Yields for multi-packs are aggregated across all cartridge slots included in the pack.
How often is it updated?
A GitHub Actions workflow runs the data pipeline automatically every 24 hours, commits the regenerated static page, and deploys it to GitHub Pages. You can watch the run history in the Actions tab.
How is ¢/page calculated?
Cost per page = (total price ÷ total page yield) × 100 cents. For combo / multi-packs the denominator is the sum of yields across all included cartridges, so the price is amortised fairly over every page those inks will print. Values below 1¢ are displayed with extra decimal places, the same way diskprices.com shows fractions of a cent per gigabyte.
Why are some listings missing?
Listings are automatically dropped if they have no parseable price, no stated or estimable page yield, or a calculated ¢/page outside the plausible range (0.001¢ – 50¢). The build log records every drop and its reason.
