কী Invoice Payment Terms Calculator?

▾

The Invoice Payment Terms Calculator analyzes early-payment discount offers (commonly notated 2/10 Net 30 — meaning '2% off if paid within 10 days, otherwise full amount due in 30 days') to compute the effective annualized return of taking vs declining the discount. The standard formula: Effective APR = (Discount% / (1 − Discount%)) × (365 / (Net Days − Discount Days)). For a 2/10 Net 30 invoice, that's (2/98) × (365/20) = 37.24% effective APR — extraordinarily attractive vs typical capital costs of 8–15%. Freelancers and B2B sellers use this in two directions. As an issuer offering terms: the discount cost (revenue forgone) is real but accelerated cash flow improves working capital and reduces collection risk. As a buyer evaluating an incoming discount offer: compare the 37% effective APR to your cost of capital (credit line rate, opportunity cost of cash sitting in operating account, or what you'd earn investing the money during the 20-day extension). If your capital cost is below the effective APR, taking the discount is positive expected value; if above (e.g., you're on a 50% APR credit card), declining is better. Common payment terms and their effective APRs: 2/10 Net 30 = 37.24% (strong incentive), 1/10 Net 30 = 18.43% (moderate), 2/10 Net 60 = 14.90% (weaker), 1/15 Net 45 = 12.29% (weak), 3/10 Net 30 = 56.44% (very strong, rare). The math heavily favors short discount windows + long net terms. Some industries use seasonal discounting (5% off in slow months) which calculates differently. The broader cash flow lesson: late-paying clients impose a hidden cost on freelancers. Net 60 vs Net 15 means working with 4× more outstanding receivables; at typical SMB credit line rates of 12% APR, every $10k of receivables held an extra 45 days costs $148 in interest. Aggressive payment terms (or factoring/invoice financing) preserve liquidity and reduce reliance on debt. This calculator gives the precise framework for making these tradeoffs quantitative rather than gut-feel.

উদাহরণ 1Standard 2/10 Net 30

প্রদত্ত:$10,000 invoice, 2% discount in 10 days, Net 30, 12% CoC

ফলাফল:$200 discount value, 37.24% effective APR — take it (37.24% >> 12%)

(2/98) × (365/20) = 37.24%. Pay $9,800 by day 10 instead of $10,000 by day 30 — yields 37% annualized.

উদাহরণ 2Weak 1/10 Net 30

প্রদত্ত:$10,000, 1% in 10 days, Net 30, 12% CoC

ফলাফল:$100 discount, 18.43% APR — still take it (18% > 12%)

(1/99) × (365/20) = 18.43%. Modest but still beats most capital costs.

উদাহরণ 3High-cost credit card buyer

প্রদত্ত:$10,000, 2/10 Net 30, but you'd put it on 24% APR credit card to pay early

ফলাফল:Decline — 37% discount APR doesn't beat 50% effective card cost

If you must borrow expensively to take the discount, decline

উদাহরণ 4Issuer perspective — offer or not?

প্রদত্ত:Selling Net 30; consider offering 2/10

ফলাফল:Cost: 2% of revenue. Benefit: 20 days faster cash, fewer late receivables. Offer if collection costs / write-offs exceed 2%

সচরাচর জিজ্ঞাসা

▾

What does 2/10 Net 30 mean?

Standard B2B invoice notation: '2% discount if paid within 10 days, otherwise full amount due in 30 days from invoice date.' Other examples: 1/10 Net 30 (1% in 10 days), 2/15 Net 45 (2% in 15 days, full in 45). The first number is the discount %, after the slash is the discount window in days, then 'Net' followed by the full-payment due date.

Why is 2/10 Net 30 such a strong incentive (37% APR)?

You're effectively paying 2% to save 20 days. 20 days is 1/18th of a year, so 2% × 18 = ~36% if you simply scaled linearly — and compounding pushes it slightly higher to 37.24%. The math is just unfavorable to declining for any buyer whose capital costs less than 37% annualized.

Should I always offer early-payment discounts on my invoices?

Depends on your collection risk and cash flow. If clients pay reliably at Net 30, you're giving up 2% revenue for marginal benefit. If you have late-payers, write-offs, or are personally taking on debt to bridge gaps, the 2% buys real protection. Run the numbers: if more than 2% of receivables become problematic, offer the discount.

What if my client pays late despite the terms?

Late payment is industry epidemic — average B2B invoice in the US is paid 7–14 days late. Strategies: charge late fees (1.5% per month is standard, but check state usury caps), tighten terms (Net 15 instead of Net 30), require deposits, or use factoring services to sell receivables for immediate cash at 1–3% discount.

Are these terms common in freelance work?

Less common than in pure B2B wholesale. Most freelancers operate Net 15 or Net 30 without early-pay discounts because invoice sizes are smaller and clients are less sophisticated about cash management. Large freelance engagements ($10k+) sometimes negotiate terms similar to B2B. SaaS and recurring services typically bill monthly upfront, bypassing this dynamic entirely.

এড়ানোর সাধারণ ভুল

▾

!Comparing nominal discount % to APR directly (2% vs 12% APR feels close but 2/10 Net 30 is actually 37% APR)
!Ignoring cash flow value of faster payment beyond the headline interest comparison
!Forgetting that taking discount uses cash that could be invested elsewhere (opportunity cost)
!Offering discounts to clients who pay reliably on time — pure revenue loss
!Not charging late fees on overdue invoices — leaves money on the table

💡

প্রো টিপ

For clients who chronically pay late, consider Net 15 with no discount instead of Net 30 with 2/10 discount — gives cleaner cash flow with less margin sacrifice. Late fees of 1.5%/month (18% APR) on overdue amounts often motivate the slow-pay clients without losing revenue from on-time payers.
