Net 60 Calculator
Enter your invoice date and get the Net 60 due date plus a full reminder schedule for follow-up emails. Everything runs in your browser — no data is stored or sent to any server.
The Net 60 Calculator is a free, browser-based tool that turns an invoice date into its Net 60 due date, a six-step reminder schedule, and — if you enter the amount — the late fee your contract accrues per day once payment is overdue. Everything is calculated locally in your browser. Updated 2026-09-10.
How It Works
The Net 60 Calculator takes your invoice date and instantly computes the payment due date 60 calendar days later. It also generates a structured follow-up reminder schedule including a 21-day reminder, a 14-day reminder, a 7-day reminder, a 3-day reminder, a due-date reminder, and an overdue follow-up for invoices that go past due.
Net 60 is a longer payment term that gives the buyer 60 calendar days from the invoice date to pay the full amount. This term applies to calendar days, not business days, so weekends and holidays are included. Net 60 is common in enterprise contracts, government procurement, large-scale manufacturing, and industries with complex accounts payable processes that require extended processing time.
Formula
Due Date = Invoice Date + 60 calendar days
21-Day Reminder = Invoice Date + 39 days
14-Day Reminder = Invoice Date + 46 days
7-Day Reminder = Invoice Date + 53 days
3-Day Reminder = Invoice Date + 57 days
Due Date Reminder = Invoice Date + 60 days
Overdue Follow-Up = Invoice Date + 67 days
When to Accept Net 60 Payment Terms
Net 60 terms are typically imposed by large corporations and government entities that have lengthy internal approval workflows. As a vendor, accepting Net 60 means you need the financial reserves to cover two months of operating expenses before receiving payment. Before agreeing to Net 60, evaluate whether the contract value justifies the extended payment window and whether your business can sustain the cash flow gap.
For freelancers and small businesses, Net 60 can be challenging. If a client insists on Net 60 terms, consider negotiating for milestone payments, a deposit, or a higher total project fee to compensate for the longer wait. Alternatively, some businesses use invoice factoring to receive immediate cash against outstanding Net 60 invoices.
Strategies for Managing Net 60 Receivables
- Require deposits or milestone payments. Break the project into phases with partial payments along the way to reduce the final Net 60 balance.
- Offer early payment discounts. Terms like 2/10 Net 60 (a 2% discount for payment within 10 days) can incentivize faster payment from clients who have the budget flexibility.
- Maintain a cash reserve. Have at least 60-90 days of operating expenses in reserve when working with Net 60 clients.
- Use multiple reminder touchpoints. With 60-day terms, you have more opportunities to send structured reminders that keep payment on the client's radar.
- Consider invoice factoring. For large invoices, factoring companies will advance you 80-90% of the invoice value immediately, collecting the full amount from your client later.
Net 60 Late Fees: What an Overdue Invoice Is Actually Worth
A due date on its own does not tell you what a late Net 60 invoice costs, which is why this calculator takes an optional invoice amount and your contract's monthly late-fee rate. The common commercial default is 1.5% per month (18% a year), so a $4,500 invoice accrues about $2.25 a day once it passes the due date — $67.50 after 30 days late. Enter your own percentage if your contract states a different figure, and check your state's usury cap before charging above 1.5% per month. Federal contracts work differently: under the Prompt Payment rule (5 CFR Part 1315) an agency that pays a proper invoice late owes interest automatically, at a rate the Treasury sets every six months, with no need for the vendor to ask.

Net 60 vs Net 30 vs Net 90: What the Longer Term Really Costs
Payment terms are a price, not a formality — every extra day is money you have financed for the client for free. Net 30 is the small-business default and the term most freelancers should quote first. Net 60 is what large enterprises and public bodies impose because their approval chains are long, and it doubles the working capital you must hold to cover the same workload. Net 90, common in retail, media buying and some construction supply chains, triples it. The practical test before accepting a longer term: could you cover payroll and your own bills for that many days with nothing coming in? If not, the right answer is not to refuse the contract but to price the delay in — add a few percent to the rate, ask for a deposit, or offer an early-payment discount such as 2/10 Net 60, which pays the client to settle in ten days. Note that the term only ever sets the due date; a late fee still needs a clause in the signed contract to be chargeable. Source: U.S. Small Business Administration — managing business finances.

Examples
Example 1: Invoice dated January 1
If you issue an invoice on January 1 with Net 60 terms, the due date is March 2 (or March 1 in a leap year). Your 21-day reminder goes out on February 9, the 14-day reminder on February 16, the 7-day reminder on February 23, the 3-day reminder on February 27, and the overdue follow-up on March 9 if payment has not been received.
Example 2: Invoice dated April 15
An invoice dated April 15 is due on June 14. Send the first reminder on May 24 (21 days before), followed by reminders on May 31, June 7, and June 11. The overdue follow-up would go out on June 21 if needed.
Example 3: Invoice dated August 1
An invoice issued on August 1 has a Net 60 due date of September 30. The 21-day reminder falls on September 9, the 14-day reminder on September 16, the 7-day reminder on September 23, the 3-day reminder on September 27, and the overdue notice would go out on October 7.
Frequently Asked Questions
Is Net 60 better or worse than Net 30 for a freelancer?
Worse for your cash flow, and it is worth saying so before you sign. Net 30 is the small-business default; Net 60 doubles the number of days you finance the work for the client out of your own pocket, and Net 90 triples it. That does not make a Net 60 contract a bad contract, but it should be priced: ask for a deposit, quote a slightly higher rate, or offer an early-payment discount such as 2/10 Net 60 so the client has a reason to pay sooner.
How much cash reserve do I need to work on Net 60 terms?
Enough to cover roughly 90 days of your own costs, not 60. The 60 days runs from the invoice date, the invoice usually goes out at the end of the work, and payment runs frequently settle a week or two after the due date. Work out your monthly fixed costs, multiply by three, and treat that as the floor before you take on a client whose standard terms are Net 60.
What is Net 60?
Net 60 is a payment term that means the full invoice amount is due within 60 calendar days from the date the invoice is issued. The "Net" refers to the total amount owed, and "60" is the number of calendar days the buyer has to pay. It is a longer payment term typically used by large enterprises, government agencies, and organizations with complex procurement processes.
Does Net 60 include weekends and holidays?
Yes. Net 60 is calculated using calendar days, which means weekends, public holidays, and non-working days are all included in the 60-day count. If the due date falls on a weekend or holiday, payment is typically expected on the next business day, though the contractual obligation remains on the calculated date.
Why do some companies require Net 60 terms?
Large corporations and government entities often require Net 60 terms because their accounts payable processes involve multiple levels of approval, budget verification, and compliance checks. These internal workflows take time, and Net 60 provides sufficient buffer for the payment to be processed without delays. Some industries, such as manufacturing and construction, also use Net 60 as a standard because of the large transaction values and complex supply chains involved.
How can I reduce the impact of Net 60 on my cash flow?
Several strategies can help: request a deposit or upfront payment before starting work, negotiate milestone-based payments throughout the project, offer early payment discounts (e.g., 2/10 Net 60), use invoice factoring to get immediate cash against outstanding invoices, or maintain a cash reserve of at least 60-90 days of operating expenses. You can also try negotiating shorter terms like Net 30 with new clients.
When should I send payment reminders for a Net 60 invoice?
For Net 60 terms, best practice is to send reminders at multiple intervals: 21 days before the due date (an early heads-up), 14 days before (a standard reminder), 7 days before (an escalated reminder), 3 days before (an urgent reminder), and on the due date itself (a final confirmation). If payment is not received, send an overdue notice 7 days after the due date.
How much late fee can I charge on an overdue Net 60 invoice?
Whatever your signed contract states — a late fee is a contract term, not an automatic right. The common commercial default is 1.5% per month (18% per year), which on a $4,500 invoice is about $2.25 per day, or $67.50 after 30 days late. Enter the amount and your contract rate in the calculator above to see the daily and 30-day figures. Check your state usury cap before charging more than 1.5% per month, and note that federal agencies pay Prompt Payment interest automatically at a Treasury-set rate instead of your contract rate.
When does the Net 60 clock start — invoice date or delivery date?
By default it starts on the invoice date, which is what this calculator uses. Some enterprise and government contracts instead start the count from receipt of a proper invoice, or from acceptance of the goods, which can push the real due date days or weeks later than you expect. Read the payment clause before you commit: if it says "60 days from receipt of a valid invoice", date your invoice the day you send it and keep proof of delivery, because that date is what the 60 days runs from.
