Cost Per Use

Cost Per Use helps you judge a purchase by estimating how much each expected use will cost. Enter a price, expected ownership period, and usage frequency to calculate cost per use. You can also include resale value and recurring maintenance costs, compare up to three products, and save calculations for later. Optional page auto-fill can read the product title and price from the active shopping page after you enable the feature and open the extension. This processing happens locally in Chrome. Page data, settings, and calculations are never sent to the developer or any third party. Features: - Cost-per-use and net-cost calculations - Product comparison - Optional active-page title and price auto-fill - Local calculation history with JSON import and export - USD, TRY, EUR, GBP, and custom currencies - English and Turkish interface - Light and dark themes - No accounts, analytics, ads, or cloud service Cost Per Use is free and open source. A voluntary Patreon link is available in the extension's Support section; it does not unlock features and is not required to use the extension.
