Money Calculators

Margin, markup, discount, tips and loan payments. Three of these get confused with each other constantly, and one of them costs more than people expect — each page shows which is which.

• Discount CalculatorEnter the original price and the discount to see the sale price and the saving.
• Margin CalculatorEnter what an item costs you and what you sell it for.
• Markup CalculatorEnter your cost and the markup you want to apply to get the price to charge.
• Tip CalculatorEnter the bill and the percentage. Tax is kept separate, because tipping on tax is a choice.
• Loan Payment CalculatorEnter the amount, the annual rate and the term. The interest total is the part a monthly figure hides.
• Sales Tax & VAT CalculatorEnter a price and a rate. The tax-exclusive and tax-inclusive figures are both shown.
• Compound Interest CalculatorEnter a starting amount, a rate and a term. What compounding adds is shown as its own figure.
