Tax on a list for prices.

Tax calculations are based on percentage rates.
Let’s start by setting the tax rate:

Go to menu  Calculation ▸ Tax & Rates… 2. Change the name if you like. It’s purely for presentation and does not affect the result.
3. Pick a keyboard shortcut that suits you.

You can also set the tax rate directly at any time.

 Example To set the tax rate to 25% Enter tax  =  25%

Other rates work the same way as tax. Let’s learn how to access them.

# Via mouse

Hold down the tax button until its menu appears. (Tax and rate names may differ as they are customizable.)

# Via keyboard

If V is your tax shortcut, pressing V repeatedly will cycle through the rates.

VTax

VVRate 1

VVVRate 2

VVVVRate 3

(Pressing V again after Rate 3 would cycle back to Tax)

For example, to set Rate 1 to 25%, press:

VV  =  25%

For illustration, we use the tax rate of 10%.

# Price with tax

 Example What is \$200 with tax? Display Enter 200 + tax Result 220

( 200 + tax  =  200 + 10%  =  220 )

So the price 220 is inclusive of tax.

# Tax subtraction

 A  General case Display Enter 220 – tax Result 198

( 220 – tax  =  220 – 10%  =  220 )

# Tax amount

We begin with the original price of \$200.

 Example What is the tax on \$200? Display Enter tax × 200 Result 20

Alternatively, you can enter:  200 ×

And you can leave out ×:  200

# Tax amount (from price inclusive of tax)

Given the price inclusive of tax is \$220, what is the tax amount?

 Hint Need to indicate 220 is inclusive. Display Enter tax × 220 inc Result 20

Alternatively:  220 ×

Or simply:  220

# Expenses, invoices, book-keeping etc.

Imagine we have a list of prices: 10, 20, 30, 40.
We want to calculate:

• Subtotal  (i.e. the sum)
• Tax amount of subtotal
• Subtotal + Tax amount  (i.e. the total)

The List drawer can help us.

# Using the List drawer

1. Open the drawer. (Shortcut: ⌘4)
2. To add the price 10 to the drawer:
Enter 10 and press return (↩).
3. Repeat for prices 20, 30, 40. 4. From the summary menu, choose ‘+ Tax’.
If the tax rate is 10%, we would have this: 5. You can also see tax for selected prices.
When you select the first price: Let’s talk about the other tax functions. The subtotal is always the sum of prices.

+ Tax’ calculates the tax amount and adds it to the subtotal.

– Tax’ is similar to ‘+ Tax’.
It subtracts the tax amount from the subtotal instead.

○ without Tax’ calculates the tax amount, assuming the prices are inclusive of tax. It then subtracts it from the subtotal. We get the total price without tax.

## Example

Knowing that 10, 20, 30, 40 with 10% tax are 11, 22, 33, 44.
Let’s enter these numbers and use ‘○ without Tax’. # Using other rates

To do so, choose More from the summary menu and select the rate you want. The summary menu now has the Rate 1 functions. # 2 nice features ## A Copy Summary
