Finance tips

💰

VAT / sales tax: "X% of Y" gives the tax amount. 20% VAT on £100 = £20 tax, total = £120. Or find the pre-tax price: total ÷ 1.20.

📈

Investment return: use "percentage change" from initial investment to current value. $1,200 → $1,500 = +25% return.

💡

Commission: 5% commission on a $4,000 sale = 5% of $4,000 = $200. Use "X% of Y" mode with X=5 and Y=4000.

🏠

Property price change: use "percentage change" to calculate how much a property has appreciated or depreciated since purchase.
