Net Terms Due Date Calculator
Enter the invoice date and the terms. The calculator counts calendar days, which is how net terms work unless a contract says otherwise.
How net terms are counted
The clock starts on the invoice date, not the date goods arrive and not the date you open the envelope. Net 30 means the full balance is due 30 calendar days later. Weekends and public holidays are included in the count unless your agreement says business days.
| Terms | Days to pay | Commonly used for |
|---|---|---|
| Net 7 / Net 10 | 7 / 10 | New accounts, small orders, higher-risk buyers |
| Net 15 | 15 | Services, freelancers, short-cycle suppliers |
| Net 30 | 30 | The common standard, and the usual starter vendor tradeline |
| Net 45 | 45 | Larger buyers negotiating longer cycles |
| Net 60 | 60 | Established relationships, bigger order values |
| Net 90 | 90 | Enterprise and government buyers |
If your terms build business credit
Paying on the due date is the whole point of a vendor tradeline. A supplier that reports your payment history turns each settled invoice into a record on your business credit file. A supplier that offers terms but reports to nobody gives you the cash-flow benefit and no credit file at all, so ask which bureaus and how often before you open an account.

Worked examples
The arithmetic is simple but the edge cases catch people out, so here are the ones that come up most:
| Invoice date | Terms | Due date | What to watch |
|---|---|---|---|
| Mon 5 January | Net 30 | Wed 4 February | Thirty days lands mid-week, no complication. |
| Thu 15 January | Net 30 | Sat 14 February | Falls on a weekend. Pay the Friday before rather than the Monday after. |
| Sat 31 January | Net 30 | Mon 2 March | Short months shift the date. February is why net 30 is not “the same date next month”. |
| Fri 20 February | Net 60 | Tue 21 April | Longer terms cross more month boundaries, so count days rather than months. |
Note the third row. Net 30 is thirty days, not one month. An invoice dated 31 January is due 2 March in a normal year, not 28 February, and that two-day difference is a late payment if you assume the month rule.
Variations you will meet in contracts
Most suppliers use plain net terms, but a few conventions change what the calculator’s answer means:
| Term | What it means |
|---|---|
| 2/10 net 30 | 2% off if you pay within 10 days, full balance due at 30. Taking the discount is usually a strong return for paying twenty days early. |
| 1/10 net 30 | The same structure with a 1% discount. |
| Net 30 EOM | Thirty days from the end of the invoice month, not from the invoice date. An invoice dated 3 March is due 30 April, not 2 April. |
| Net 30 ROG | Thirty days from receipt of goods. The clock starts on delivery, which can be days or weeks after the invoice. |
| Due on receipt | Not a net term at all. Payment is expected immediately and nothing is being financed. |
The calculator above counts plain calendar days from the invoice date, which covers the large majority of B2B invoices. If your agreement says EOM or ROG, adjust the start date before entering it.
Why the due date matters more on a young credit file
If your supplier reports to the business credit bureaus, the due date is not just a cash-flow deadline, it is the thing being measured. A tradeline records whether terms were met as agreed, so the difference between paying on the due date and paying three days later is the difference between a positive entry and a negative one.
That gap costs disproportionately on a thin file. A business with two years of history absorbs one late mark; a business with three months of history does not, because there is almost nothing else recorded to weigh against it. If your payment run is weekly, the safe habit is to pay the run before the due date rather than the one after, and to treat a weekend due date as falling on the preceding Friday.
It is also worth knowing that paying early does not score better than paying on time. On-time is the standard being measured, so there is no credit advantage in settling on day two rather than day thirty. What early payment does buy you is a discount where one is offered, and a clear line for the next order.
Questions about net terms
Does net 30 mean 30 business days or calendar days?
Calendar days, unless the contract explicitly says business days. Thirty calendar days from a Monday invoice lands roughly four weeks and two days later, weekends included. If a supplier means business days they have to say so, because the default reading is calendar.
When does the clock start — invoice date or delivery date?
The invoice date in almost all cases. Some contracts specify receipt of goods or receipt of invoice instead, which can shift the due date by several days, so it is worth checking rather than assuming.
What happens if the due date is a weekend or holiday?
Practice varies. Many suppliers accept the next business day; others count the calendar date strictly. If your payment run is weekly, pay the business day before rather than after, because a late mark on a thin credit file costs far more than paying two days early.
What is 2/10 net 30?
It means a 2% discount if you pay within 10 days, with the full balance due at 30. Worth taking when your cash allows, because 2% for paying 20 days early is a strong effective return.
Is net 60 or net 90 better than net 30?
Better for your cash flow, harder to get. Longer terms are usually offered to established buyers with a trading history. If you are building a credit file, net 30 accounts are the standard entry point and report exactly the same as longer terms.
Does paying early improve my business credit more?
No. On-time is what gets reported and on-time is the standard measured against. Paying early frees the account for your next order sooner, but it does not create a stronger entry than paying on schedule. What genuinely damages a young file is paying late.
This calculator counts calendar days from the invoice date. Your own supplier agreement takes precedence. Nothing here is financial or legal advice.
