Need to send professional invoices with tax calculated automatically? Excel is a powerful tool for small business owners and freelancers who need customizable, tax-ready invoice templates.

This step-by-step guide will show you how to create an Excel invoice template with automatic VAT or sales tax calculation built in.

1. Layout Your Invoice Template

Start with a clean layout. Use the top of the sheet for company details and the client’s information.

• A1–A3: Your business name, address, phone
• C1–C3: Client name and address
• A5: Invoice number
• C5: Invoice date

2. Create the Itemized Section

Add column headers:

• B7: Item Description
• C7: Quantity
• D7: Unit Price
• E7: Total (Quantity × Unit Price)

In cell E8, use this formula:

=C8*D8

Drag the formula down to support more rows.

3. Add Tax Calculation

Below the items list, include:

• Subtotal: =SUM(E8:E20)
• Tax Rate (%): Enter manually or link from another cell (e.g., F22)
• Tax Amount: =Subtotal * Tax Rate
• Total Amount: =Subtotal + Tax

💡 Example:

F22 (Tax Rate) = 0.20  (for 20% VAT)
F23 (Subtotal) = SUM(E8:E20)
F24 (Tax)      = F23 * F22
F25 (Total)    = F23 + F24

4. Make It Reusable

• Use data validation to prevent input errors in quantity and price
• Format totals as Currency
• Lock formula cells and protect the sheet
• Save as Excel Template (*.xltx)

5. Optional: Add Currency or Multi-Tax Support

For international use, add dropdowns to select currency symbols or multiple tax rates. You can use named ranges and VLOOKUP for dynamic tax handling.

With just a few formulas and formatting tweaks, you can build a powerful tax-ready invoice in Excel.

Manipulating dates and times in Excel using VBA opens up a world of automation and custom functionality that goes far beyond what standard worksheet functions can offer. While Excel itself is quite good with dates (storing them as serial numbers), VBA gives you programmatic control to parse, calculate, format, and interact with dates and times in powerful ways. Let’s see how you can wield this capability.

Imagine you and your friends decide to rent a vacation home for a weekend. The total cost for the stay is $600. However, not everyone can stay for both nights. You need to figure out how much each person should pay, ensuring it’s fair, based on the number of nights they’re staying. This is a perfect scenario for using pro rata calculations, and Excel is our tool of choice to solve this puzzle.

Adding a zero before numbers or text in Excel is a common requirement, especially for data that needs to maintain a certain format, like ZIP codes, phone numbers, or numerical codes. Excel, by default, might not display leading zeros since it interprets the data as numbers. Here are several methods to achieve this, ensuring your data is displayed exactly as needed:

You know, in the world of research, it’s so common to fixate on that p-value. That tiny number, often below 0.05, signals “statistical significance!” It tells us, loud and clear, that the difference we found in our data probably isn’t just random chance, which is awesome. But here’s the thing, and it’s a critical point in modern research: “statistically significant” doesn’t automatically mean “practically important” or “a big deal”. A microscopic, almost trivial difference can show up as significant if your study has a huge number of participants. And conversely, a really meaningful difference might not quite hit that magic p-value if your sample is on the smaller side.

So, what’s often missing when we only look at p-values is the magnitude of that difference, the “how much does it actually matter?” question. That’s precisely where Cohen’s d steps in. It’s a powerhouse tool that lets you quantify the effect size – basically, how big and meaningful the difference between your two group averages really is, in a way that’s standardized and makes sense regardless of what you measured. It truly helps you answer that “so what?” question, and the cool part is, you can calculate it right there in your everyday Excel spreadsheet. Let’s just walk through it.
