Free invoicing calculators

Small calculators for the sums that come up when you invoice. You type every figure; nothing is stored or sent anywhere.

• Invoice due date calculatorPick the invoice date and the payment terms and see the date the invoice is due, and which day of the week it falls on.
• Discount calculatorEnter a price and a percentage off to see how much the discount is and what is left to pay.
• Late fee calculatorEnter what is overdue, the fee rate you state on your invoices and how many periods it has been late.
• Sales tax calculatorEnter a price and the tax rate that applies to you. The calculator does the arithmetic; it does not know any rates.
• Markup and margin calculatorEnter what something costs you and the markup you want to see the price to charge, your profit and your margin.
• Hourly rate to project price calculatorEnter the hours you expect, your hourly rate, any expenses and a buffer for the unexpected to get a price you can quote.
