How it works
Invoice Total Calculator is the page for the moment a output stops being a guess: enter the real Subtotal, Tax Rate %, and Discount % and follow the working down to the last operation.
Using the Invoice Total Calculator
- Subtotal — independent among the invoice total fields — changing it alone moves the result.
- Tax Rate % — used once on invoice total, and worth a second glance if the figure looks off.
- Discount % — the Career & Freelance field that most often arrives from another document; re-check its scale.
- Compare the result from Invoice Total Calculator with the figures above it; the intermediate values are where a wrong unit usually shows up first.
- Switch one field at a time in Invoice Total Calculator and note the change each time; that short list of movements is a sensitivity check you can explain.
The formula behind the result
The order of operations on the invoice total page is fixed by the Career & Freelance convention, which is why two runs with identical Subtotal, Tax Rate %, and Discount % cannot disagree.
Worked example: with subtotal of 1,000, tax rate % of 10, discount % of 5, this invoice total calculation returns Total: $1045.00. The same run reports Subtotal: $1000.00 | Discount: -$50.00 (5%) | Tax: $95.00 (10%).
Understanding the result
The total answers the question you asked, not the one you meant; if it reads oddly, re-check what the Subtotal, Tax Rate %, and Discount % describe.
