What is the Net Terms Calculator?

The Net Terms Calculator is a free tool that instantly computes invoice due dates based on your chosen payment terms. Whether you use standard Net 30, early payment discount terms like 2/10 Net 30, or End of Month billing, this calculator gives you the exact due date and a visual payment timeline.

Understanding and correctly applying payment terms is essential for maintaining healthy cash flow. Miscalculating a due date can lead to missed payments, strained client relationships, or unnecessary late fees. This tool eliminates guesswork and ensures both you and your clients are on the same page.

Here is what the Net Terms Calculator helps you do:

Step-by-Step Guide

1

Select your payment terms type

Choose from the dropdown menu of common payment terms. Options include Due on Receipt, Net 15, Net 30, Net 45, Net 60, Net 90, End of Month (EOM), 2/10 Net 30, or Custom. If you select Custom, an additional field appears where you can enter any number of days. The calculator defaults to Net 30, the most common business payment term.

Enter the invoice date

Select the date the invoice was issued using the date picker. The calculator automatically sets today's date as the default. If you are calculating terms for a past invoice, simply change the date to match the original invoice date. You can also optionally enter the invoice amount to calculate early payment discount savings.

View the calculated due date and early payment deadline

The results panel updates instantly, showing the exact due date, the number of days remaining (or overdue), and the payment terms label. If you selected 2/10 Net 30 and entered an invoice amount, you will also see the early payment discount deadline, the discount amount (2%), and the discounted total. A visual timeline bar shows where today falls between the invoice date and the due date.

The glossary covers Net 30, Net 60, 2/10 Net 30, Due on Receipt, End of Month, COD, CIA, and more. There is also an advice section that recommends which terms to use based on your business type and client relationships.

Tips & Best Practices

Start with shorter terms for new clients

Use Net 15 or Due on Receipt until a client has established a reliable payment history. You can always extend terms later as trust builds, but shortening terms after they have been set can damage the relationship.

Offer early payment discounts

Terms like 2/10 Net 30 incentivize clients to pay faster. A 2% discount for paying 20 days early equates to roughly 36.7% annualized return, making it a worthwhile trade-off for improved cash flow.

Clearly state terms on every invoice

Never assume clients remember your terms. Print the payment terms, due date, and any discount deadlines directly on every invoice you send. Ambiguity leads to late payments.

Use automated reminders as due dates approach

Send a friendly reminder a few days before the due date, then follow up promptly if payment is late. TapDue can automate this entire workflow so you never have to chase payments manually.

Frequently Asked Questions

What does Net 30 mean?
Net 30 means the full invoice amount is due within 30 calendar days from the invoice date. It is the most common payment term in business-to-business transactions. For example, an invoice dated January 15 with Net 30 terms would be due by February 14. Net 30 gives clients a reasonable window to process payment while keeping cash flow relatively predictable for the seller.
What is 2/10 Net 30?
2/10 Net 30 is a discount payment term. The buyer receives a 2% discount if they pay within 10 days of the invoice date. If they do not take the discount, the full amount is due within 30 days. On a $10,000 invoice, paying within 10 days would save $200. This structure incentivizes early payment and significantly improves cash flow for the seller.
Which net terms should I offer?
It depends on your business type and client relationship. Freelancers and solopreneurs should start with Net 15 or Due on Receipt for new clients. Small businesses selling B2B typically use Net 30 as the standard. For high-value or custom projects, consider requiring a deposit upfront. You can always adjust terms as trust develops. Use our calculator to model different scenarios.
Can I change terms for different clients?
Absolutely. Tailoring payment terms to each client is a common and recommended practice. Offer shorter terms (Net 15) for newer or higher-risk clients, and extend terms (Net 30 or Net 60) for established, reliable clients. Just ensure the agreed-upon terms are clearly documented on every invoice and in any contracts.
How do EOM terms work?
End of Month (EOM) terms mean payment is due by the last day of the month in which the invoice was issued. An invoice dated March 5 with EOM terms is due March 31. An invoice dated March 28 is also due March 31. EOM simplifies accounting by consolidating all payments to a single date each month. Variations include EOM + 15, meaning payment is due 15 days after month-end.

Stop chasing payments manually

TapDue calculates due dates, sends reminders on a smart schedule, and helps you get paid faster. Set your terms once and let automation handle the rest.
