Invoicing & Payment Calculators

Get invoices right, understand your payment terms and see what slow payers are costing you.

• Invoice Late Fee CalculatorWork out interest and flat fees on an overdue invoice.
• Invoice Total CalculatorAdd labor, materials, discounts, tax and deposits for the amount due.
• Early Payment Discount CalculatorFind the real annual cost of terms such as 2/10 net 30.
• Payment Processing Fee CalculatorSee what card fees take, and what to charge to net a set amount.
• Days Sales Outstanding CalculatorMeasure how long customers take to pay and the cash it ties up.

Getting paid accurately

Use the invoice total calculator to check an invoice before you send it. If you take cards, the payment processing fee calculator shows what you keep. When an invoice goes overdue, the late fee calculator applies the terms you agreed with your customer.

Getting paid faster

The days sales outstanding calculator shows how long customers really take to pay. If it is well beyond your terms, an early payment discount may help, though the annual cost is higher than it looks.

These tools use the rates and terms you enter. They do not supply tax rates or check legal limits on fees, since those differ by location and change over time. Check your local requirements or ask a professional.
