Accessible, transparent arithmetic

Every cash calculator runs in your browser, shows its formula, and uses data you can inspect and edit.

Calculations run locally with plain HTML, CSS, and vanilla JavaScript inside each tool. Inputs never leave the page, so salary, loan, and budget figures stay in your browser. Each tool states the formula it uses, such as the loan EMI formula, so you can verify the arithmetic yourself.

Rates, consumer price data, and cost-of-living indexes are stored in editable datasets with a stated source and date. Where data is missing for a selection, the tool says so instead of estimating. All results are informational reference estimates, not financial advice.
