Invoice Due Date Calculator
Calculate invoice due dates based on issue date and payment terms.
Payment terms like "Net 30", "2/10 Net 30", and "Due on receipt" are industry standard but require date arithmetic to determine the actual due date. This calculator converts any payment term into a specific calendar date from your invoice date, including early payment discount deadlines.

Frequently Asked Questions
What do Net 30, Net 60, and Net 90 mean? ▼
These are standard payment terms. Net 30 means payment is due within 30 calendar days of the invoice date. Net 60 = 60 days, Net 90 = 90 days. "Net" refers to the full amount owed. Some terms include early-payment discounts like "2/10 Net 30" (2% discount if paid within 10 days).
What payment terms should I use for invoices? ▼
Net 30 is the most common for business-to-business invoices. Small businesses and freelancers often use Net 15 or "Due on Receipt" for faster cash flow. Larger contracts may use Net 60 or Net 90. Choose terms that balance client relationships with your cash flow needs.
What happens if an invoice is paid late? ▼
Late invoices disrupt cash flow and may incur late fees (typically 1–2% per month). Many businesses send reminders at 7 days past due, a formal notice at 30 days, and escalate to collections at 90+ days. Always state late payment penalties clearly on your invoices.
How do I improve invoice payment times? ▼
Offer early-payment discounts (e.g., 2% off for payment within 10 days), send invoices promptly, use online payment options, set clear terms upfront, and send friendly reminders a few days before the due date. Automated invoicing software also helps significantly.
Do weekends and holidays count in payment terms? ▼
Standard Net payment terms count calendar days, including weekends and holidays. If the due date falls on a weekend or public holiday, payment is typically expected on the next business day, though this varies by contract.
