Taxes
Income Tax Calculator
Calculate income tax owed by applying a flat tax rate to total income β a simplified shortcut for estimating tax burden in flat-rate jurisdictions or for back-of-envelope marginal-rate math. Use it for quick gut-checks; for real US federal tax which uses progressive brackets, use a dedicated tax-bracket calculator instead.

Ecommerce
Sales Tax Calculator
Calculate the sales tax owed on an ecommerce purchase given the pre-tax order amount and the applicable tax rate. Use it for collecting the right tax from customers at checkout, estimating tax liability for a sale, or verifying that your store's tax calculation matches the destination jurisdiction's rate.
