Net 60 Days Calculator

Net 60 gives a buyer 60 calendar days to pay an invoice in full, and the only hard part is landing on the right date: count wrong by one day and a payment looks late when it is not, or overdue charges start a day early. Enter the invoice date below and this calculator adds exactly 60 calendar days, weekends and holidays included, and names the due date.

Quick Answer

How to use the Net 60 calculator

Pick the invoice date, click Calculate due date, and read the date payment is due. One input is all the term needs, because Net 60 fixes the length of the credit period at 60 days.

1. Enter the invoice date: use the date printed on the invoice, pre-filled here with August 1, 2025 from the worked example below. If your contract starts the term on delivery or on receipt, enter that date instead.
2. Click Calculate due date: the tool adds 60 calendar days, rolling correctly across month ends and leap years, and shows the result as a weekday and date.
3. Read the weekend badge: a green badge means the due date is a weekday. An amber badge means it falls on a Saturday or Sunday, which is worth a line in the invoice notes because many accounts payable departments only run payments on business days.
4. Copy or share the result: the Copy and Share buttons send the due date with its working, handy for pasting into the invoice itself or an email to the buyer.

Leaving the date blank is the only way to get no answer: the tool asks you to select an invoice date rather than guessing at today. That is deliberate. A due date computed from the wrong start date is worse than no due date at all.

The Net 60 formula and the counting rule behind it

Due Date = Invoice Date + 60 calendar days. The invoice date itself is day zero, the next day is day 1, and the 60th day is the due date.

Three counting details decide whether you land on the right day. First, the days are calendar days: Saturdays, Sundays and public holidays all count, which is the standard reading of net terms in trade practice. It is also the reading behind the European rules on combating late payment in commercial transactions, where 60 days is the general ceiling for business payment periods unless both sides agree otherwise. Second, the start date is excluded from the count: you count forward starting the day after the invoice date, which is why October 15 plus 60 days is December 14 and not December 15. Third, month lengths and leap years are handled by real calendar arithmetic, so a February 29 invoice in a leap year still lands 60 true days later.

Why does a written term matter at all? Because the legal default is far shorter. For the sale of goods, UCC Section 2-310 makes payment due on delivery when the contract says nothing about credit. Net 60 is the agreed exception to that default, which is why it has to be agreed before the invoice goes out, not argued about after.

Worked example: an August 1 invoice, checked three ways

The example is an invoice dated Friday, August 1, 2025, due Tuesday, September 30, 2025. You can check it by hand, by month, or against the other common terms in the table below.

The same invoice under the neighbouring terms shows how much the term itself moves the date. Net 30 pulls payment a full month earlier; Net 90 pushes it into late October.

Sellers feel that spread in cash, not just on the calendar. Waiting 60 days instead of 30 ties the money up twice as long, which is why your days payable outstanding on the buying side and the receivables equivalent on the selling side both move when a big customer negotiates Net 60. If you are the seller, the practical defences are boring but effective: invoice on the day of delivery, name the due date on the invoice, and send the first reminder before the date, not after it.

What 60 days of waiting actually costs the seller

Net 60 is two months of interest free credit handed to the buyer. On a $25,000 invoice, a business funding that gap at an 8 percent annual borrowing cost pays roughly $329 in financing cost for the 60 days ($25,000 × 8% × 60 ÷ 365), before counting any chasing time.

That cost is the reason discount terms exist. Under 2/10 Net 60, the buyer can take 2 percent off for paying on day 10 instead of day 60. Skipping that discount to use the full 60 days costs the buyer an effective annual rate of about 14.9 percent on the money, a figure that follows straight from the discount arithmetic: 2 percent for 50 days of earlier payment, annualised. Buyers with cheap credit lines take the discount; sellers offer it because day 10 cash is worth more than day 60 cash. Either way, both dates come off the same invoice date, and the day 60 date is the one this page computes.

The public sector shows the contrast. Federal prompt payment rules generally pay within 30 days, and the FAR prompt payment clause builds interest penalties around that window. Private Net 60 terms carry no automatic penalty at all: whatever happens after day 60 is whatever your contract says, which is why the late fee and interest wording matters as much as the due date itself. When a payment does slip past the date, a late payment calculator turns the overdue days into an interest figure you can put on the statement.

A reminder schedule that fits a 60 day term

Most Net 60 invoices are paid by whoever gets reminded at the right moments. Four touches cover the term without nagging.

1. Day 0: send the invoice with the term and the named due date on it, and confirm the buyer has the right address for remittance questions.
2. Day 45: a short courtesy note: the invoice is due in 15 days, on the named date. This is the reminder that catches invoices stuck in an approval queue.
3. Day 55: restate the amount and the due date, and ask the buyer to flag any dispute now, while there is still time to fix paperwork before day 60.
4. Day 61: the invoice is overdue. State the number of days late and any interest or fee the contract provides for, and track the ageing alongside your days sales outstanding so one slow payer does not hide inside a healthy average.

None of this changes the due date. It changes whether the due date is the day the money arrives or the day the arguing starts.

What competing calculators miss

Due date tools cluster into a few types, and each leaves a gap this page closes:

• Multi-term tools (TapDue, PerfectParser, MZTechPro): they handle Net 15 through Net 90, EOM and discount terms from one dropdown, which is flexible, but the extra modes are also extra ways to get the wrong answer: pick Net 30 out of habit on a Net 60 contract and the date is a month early. They also tend to report only the date, with no weekend warning. This page does one term, on purpose, and flags the weekend case.
• Spreadsheet templates: a VLOOKUP over a terms table plus invoice date arithmetic works until someone fills the formula down wrong or types the term differently from the table. The arithmetic is right; the process around it is fragile.
• Guides with no tool (payment terms explainers): accurate definitions and a worked example or two, but you still count the days yourself for your own date, which is the step where off-by-one errors happen.
• The quiet time zone bug: tools that parse a typed date as UTC midnight and display it locally return a due date one day early for users in the Americas. An August 1 invoice shows September 29 instead of September 30. This calculator parses the date in local time, and the fix is documented in the worker notes for this page: the answer is September 30 in every time zone.
• The gap this page fills: one term done exactly, the count shown step by step, a weekend badge on the result, a reminder schedule matched to the 60 day window, and copy and share buttons so the date travels with its working.
