Calculator Toolkit is a private, browser-based set of calculators for restaurant tips and split bills. Enter the bill, choose a tip, decide whether tax belongs in the tip basis, and split the final amount with clear per-person totals. Calculations run locally in your browser, and the current version does not require an account.
I built Calculator Toolkit to make common restaurant-payment decisions easier to check. A tip percentage can be clear while the final split is not, especially when people disagree about whether tax belongs in the tip basis. The tool keeps the bill, tip, total, and per-person amounts visible together and runs the calculation locally in the browser.
