1) Does the calculator calculate gross or net?
You enter items as net. VAT is added optionally at the end – you get both net and gross.

2) How do Overhead & Profit work?
Both markups are calculated based on the (discounted) subtotal. This ensures the discount is accounted for correctly.

3) Percent or Dollar discount – which is better?
Percent is ideal for variable sums, Dollar discount for fixed promotions (e.g., "$100 off").

4) Is this a legally binding offer?
No – it is a calculation tool. You must add legal texts, service descriptions, payment terms, etc. separately.

5) Can I export items?
Yes: "Copy as Text" creates a clean summary including amounts. For spreadsheet export, you would need an advanced version.

6) Why does the Hourly Rate Check show "—"?
Because no hours are entered. As soon as you enter hours > 0, you will see the effective net hourly rate.

This Offer Calculation Tool helps you quickly calculate a professional offer from individual line items – without Excel chaos. You start with the items: Each position consists of a description, quantity, and unit price (net). The calculator automatically sums the item total (Quantity × Unit Price) and adds all items to the subtotal. This gives you a clean basis, whether you offer craft services, agency packages, consulting, events, or maintenance.

Next come the conditions: You can enter a discount as a percentage or as a fixed Dollar amount. Percent is useful if you want to remain flexible (e.g., 5% on larger orders). A fixed amount is suitable for clear promotions (e.g., "$200 discount on bookings by end of month"). The calculator subtracts the discount from the subtotal so that all subsequent calculations remain fair and traceable.

Now it gets truly calculatory: Overhead and Profit Markup. Overhead costs are all indirect costs that are often "invisible" in projects: Administration, communication, tools, software, rent, insurance, or your own project coordination. Many offers fail because these costs are forgotten. With the Overhead Markup, you can price them in by percentage – transparently and consistently. Additionally, you can set a Profit Markup, i.e., your desired margin. Both markups are calculated on the discounted subtotal, so that discount and margin fit together logically.

Optionally, you can add a Travel or Material Flat Fee. This is practical if you don't want to list fixed arrival costs, logistics, or small parts individually. Then you select the Sales Tax / VAT (0%, 7%, or 19%). The calculator shows net, VAT, and gross separately – ideal to immediately see the number that will be on the offer at the end, without losing the net logic.

The Hourly Rate Check is the bonus for true profitability: Enter planned hours (e.g., 12 hours) and the calculator calculates the effective net hourly rate (Net Offer / Hours). If you also store a target hourly rate, you get a note whether your offer is "green" (above target) or "red" (below target). This way, you recognize immediately if you should recalculate – before you send the offer.

For practical use, there is the Text Output: With one click, you generate a compact summary that you can copy into an email, a PDF offer, or your proposal tool. The calculator runs completely in the browser – no data is sent to servers, making it ideal for data-thrifty websites. If you want more later, you can add features like item VAT, tiered pricing, PDF export, or offer numbers. For the start, this calculator delivers a strong, understandable calculation and ensures that you create offers faster, cleaner, and more profitably.
