Formula and Logic
This calculator uses standard B2B trade finance formulas to evaluate open account terms:
- Early Payment Discount Amount = Invoice Amount ร (Discount Percentage / 100)
- Daily Cost of Capital = (Annual Cost of Capital / 100) รท 365
- Opportunity Cost of Waiting = Invoice Amount ร Daily Cost of Capital ร Credit Term Days
- Expected Bad Debt Loss = Invoice Amount ร (Bad Debt Risk / 100)
- Net Profit After Bad Debt = (Invoice Amount ร Profit Margin / 100) - Expected Bad Debt Loss
- Buyer Effective APR (for early payment discounts) = (Discount % / (100 - Discount %)) ร (365 / (Credit Term Days - Discount Period Days)) ร 100
All calculations assume standard 365-day years and do not account for compounding interest.
Practical Notes
Open account terms are a common B2B trade practice, but require careful evaluation to protect margins:
- Typical bad debt risk for open account terms ranges from 1-5% for established buyers, up to 10% for new partners.
- Most small businesses use an annual cost of capital between 6-15%, reflecting average business loan rates.
- Common early payment discount terms like 2/10 Net 30 offer buyers an effective APR of ~37%, which can incentivize faster payment.
- Always set credit terms shorter than your own accounts payable terms to avoid cash flow gaps.
- Profit margins below 15% may not cover opportunity costs and bad debt risk for long credit terms (60+ days).
Why This Tool Is Useful
Offering open account terms can help you win more B2B clients, but poorly structured terms can hurt cash flow:
- Quantify the true cost of tying up capital in unpaid invoices.
- Evaluate if early payment discounts are cost-effective for your business.
- Set minimum invoice amounts to ensure profitability even with bad debt losses.
- Compare different credit term options to find the right balance between client incentives and financial risk.
- Make data-driven decisions instead of relying on guesswork for trade agreements.
Frequently Asked Questions
What is an open account term?
An open account term is a B2B payment agreement where the buyer receives goods or services first, then pays the seller at a later date (typically 15-90 days after delivery). This is different from cash-in-advance or letter of credit terms, which require payment before delivery.
How do I set a fair bad debt risk percentage?
Review your historical invoice data: divide total unpaid invoices over the past year by total invoice volume to get your baseline bad debt rate. For new buyers, use industry benchmarks (1-3% for established industries, 5-10% for high-risk sectors) until you have your own data.
When should I offer early payment discounts?
Offer early payment discounts if your annual cost of capital is higher than the effective APR the discount offers to buyers. For example, if your cost of capital is 10% and a 2/10 Net 30 discount offers buyers a 37% APR, the discount is cost-effective if faster payment reduces your capital costs more than the discount amount.
Additional Guidance
Use this calculator to align your open account terms with your business goals:
- For e-commerce sellers: Keep credit terms to 15-30 days to match platform payout cycles.
- For wholesalers: Use 60-90 day terms for large volume buyers, but require credit checks first.
- Always include late payment fees in your contracts to offset delays beyond the credit term.
- Re-evaluate your terms quarterly as your cost of capital and bad debt risk change.
