Quote line calculation with discount and tax

Freelancers and small businesses can calculate a quote when a discount or tax must be reflected in the amount shown on its line items.

Price every quote line with its discount and tax, producing a coherent calculation for the amount that will be presented to the customer.

How to use

Enter the overall discount percentage first, then the tax rate percentage, keeping each value on its own line.
Add one line per item using the label, semicolon, quantity, semicolon, unit price pattern.
Check the line order and punctuation, then run the calculation to produce the amounts.
Read the result line by line and confirm that the discount and tax match the quote you intend to send.
Clear the form to start over, or import a supported text file if your data is already prepared.

Example

The sample starts with a 10 percent overall discount and a 20 percent tax rate, followed by two service lines with quantity and unit price. After calculating, look at how each line is priced and how the total reflects the discount and tax without copying those values into your own quote.

Input

Consulting service ; 3 ; 150
Maintenance ; 1 ; 80

Limits and formats

The tool calculates amounts, but it does not create a signed commercial document or a legally compliant invoice.
It does not choose a currency and may not round exactly like your billing software, so review the result before presenting it.
Each item line must follow the requested pattern; a misplaced comma or semicolon can distort the calculation.
Imports can include text, CSV, JSON, MD, XML, and YAML files, but a poorly structured file may be rejected.

Where processing happens

The whole calculation runs in your browser, so the percentages, line items, and totals remain on your device and are not sent anywhere. You can test several pricing scenarios without transmitting your rates to an outside service.

Frequently asked questions

How do I enter a discount that applies to every line?

Put the overall discount on the first line, before the item lines. The tool then applies it to the calculation according to the expected format, and you can inspect each amount in the result.

Can I import an existing quote instead of typing everything again?

Yes, the tool accepts a prepared text or tabular file in the listed formats. Put the same information in the required order, import the file, and review the output before using it.

Is tax calculated after the overall discount?

The form expects the global discount, then the tax rate, followed by the item lines. To avoid a surprise, compare the total with your own pricing rule and change the input if your business logic differs.
