Building up a freelance invoice with multiple work items — different tasks each billed at their own hours and rate — means summing several line items individually, which this calculator handles automatically as you add each one.
Add a line item for each piece of work with its hours and hourly rate, and the tool multiplies and sums them into a running subtotal, then applies any tax or fee percentage to calculate your final invoice total.
This is useful for freelancers building an itemized invoice with mixed billing rates across different types of work, or anyone wanting a quick running total before formatting the final invoice document to send to a client.

Frequently asked questions
Can different line items have different hourly rates?
Yes, each line item has its own independent hours and rate fields, so you can bill different tasks at different rates within the same invoice.
Does this generate an actual formatted invoice document?
No, this calculates the total only; you'd still need to format the final line items into your invoice template or document for sending to the client.
