How this works and common questions
About this tool
Each payment times the percent you type. The result is the running total. A simple estimate, not advice. Not tax advice. Nothing you type leaves this device.
How it works
Each payment is multiplied by the percent you type and rounded half up to the cent. The running total adds those amounts in order. 25 percent of 1000.00 is 250.00. 25 percent of 400.00 is 100.00. The running total is 350.00. The result sentence and the CSV list every payment.
Rules
You type the percent. This page does not look up a tax rate or an instalment. It is an estimate of the percent you type, not tax advice. Verify with the official source.
