What does Net 30 mean on an invoice?

Net 30 means the full invoice amount is due within 30 calendar days of the invoice date. So an invoice dated June 1 with Net 30 terms is due by July 1. Net 15, Net 45 and Net 60 work the same way with their respective day counts.

What is a 2/10 Net 30 early payment discount?

2/10 Net 30 means the client can take a 2% discount if they pay within 10 days; otherwise the full amount is due in 30 days. The early payment discount is an incentive for faster payment, and the due date calculator shows exactly when the discount deadline falls.

Is this calculator free?

Yes, completely free. It runs in your browser with no account and nothing uploaded. There is no paid version.

Can I save past invoice due dates?

Yes. The calculator saves your recent calculations locally so you can recall them quickly.

Know exactly when to expect payment

Payment terms like "Net 30" or "2/10 Net 30" sound simple, but when you send a lot of invoices to different clients on different dates, keeping track of when each one is due — and whether you can still offer the early-payment discount — takes effort. This calculator removes the arithmetic.

Enter the invoice date and pick a payment term. The calculator shows the exact due date with the day of the week, how many days remain from today, the early-payment discount deadline if you offer one, and a four-date cash-flow timeline: invoice sent, early-payment deadline, due date, and a follow-up reminder.

What it shows

Exact due date

The full date including day of the week — "Monday 6 July 2026" — so there is no ambiguity.

Days remaining

Positive = future; zero = today; negative = overdue, shown with a red warning.

Net 7 to 90 + custom

All common payment terms plus a custom-days input for non-standard arrangements.

Early-payment discount

Set a discount % and days (e.g. 2/10) to see the discount amount and the exact deadline.

Cash-flow timeline

Four key dates in one view: sent, early-pay deadline, due date, and 30-day follow-up.

Save recent calculations

Recall the last few calculations from local storage — no re-entry needed.
