đź’ˇ Tip: Enter your business's annual cost of capital to see if the discount's effective rate beats your capital costs.
How to Use This Tool
Start by selecting your calculation perspective: choose "Seller" if you’re offering payment terms to customers, or "Buyer" if you’re evaluating early payment discounts from suppliers.
Enter the total invoice amount for the transaction, then input the cash discount rate (e.g., 2 for 2% off), the number of days customers have to pay to get the discount, and the full net terms period (e.g., 30 days for standard net 30).
Add your business’s annual cost of capital: this is the interest rate you pay to borrow funds, or your opportunity cost for tied-up cash. Click "Calculate Comparison" to see detailed results, or "Reset" to clear all fields.
Use the "Copy Results to Clipboard" button to save your comparison for records or team discussions.
Formula and Logic
This calculator uses two core formulas to compare cash discounts and net terms:
- Effective Annual Percentage Rate (APR) of the cash discount: (Discount Rate / (1 - Discount Rate)) * (365 / (Net Terms Period - Discount Period)) * 100. This converts the early payment discount into an annualized rate to compare against your cost of capital.
- Discounted Payment Amount: Total Invoice Amount * (1 - (Discount Rate / 100)). This is the amount you receive (or pay) if you take the early payment discount.
The tool compares the discount’s effective APR to your annual cost of capital: if the effective APR is higher than your capital cost, the discount is financially beneficial. If not, standard net terms are better for cash flow or margin preservation.
Practical Notes
For small business owners and e-commerce sellers, cash discounts are most useful for improving short-term cash flow, even if the effective APR is slightly lower than your capital cost, if you have immediate operational expenses.
Traders and B2B sellers should align discount periods with their own accounts payable terms: if you have to pay suppliers in 15 days, offering a 2/10 net 30 discount lets you get paid before your own bills are due.
Avoid offering discounts with effective APRs above 50% unless you have severe cash flow constraints: high discount rates can erode margins quickly for low-margin products.
Buyers should only take cash discounts if the effective APR is higher than their own cost of capital, or if they have excess cash on hand with no higher-yield investment options.
Why This Tool Is Useful
Most businesses default to standard net 30 terms without calculating the true cost of early payment discounts. This tool eliminates guesswork by quantifying the exact tradeoff between getting paid early and waiting for full payment.
It helps sales teams set competitive yet profitable payment terms, and lets procurement teams evaluate supplier discount offers to reduce costs without hurting cash flow.
By showing the annualized impact of discounts, it helps business owners make consistent, data-driven decisions across all B2B transactions, rather than ad-hoc choices per invoice.
Frequently Asked Questions
What is a typical cash discount for net terms?
Common terms are 2/10 net 30 (2% discount if paid in 10 days, full amount in 30 days) or 1/10 net 30. These equate to effective APRs of ~37% and ~18% respectively, which are often higher than small business loan rates, making them attractive for sellers to offer if they need cash fast.
Should I offer cash discounts to all customers?
Only offer discounts to customers with a history of on-time payments: late-paying customers may take the discount and still pay late, costing you both the discount and the wait time. You can also limit discounts to high-volume or high-margin customers to preserve profitability.
How do I calculate my annual cost of capital?
Your cost of capital is the weighted average of all your funding sources: if you have a business credit card at 15% APR and a loan at 8% APR, with 60% of funds from the loan and 40% from the card, your cost of capital is (0.6*8) + (0.4*15) = 10.8%.
Additional Guidance
Test different discount rates and periods to find the sweet spot for your business: a 1% discount for 10 days net 30 has a much lower effective APR than 2/10 net 30, which may be enough to incentivize early payment without hurting margins.
For e-commerce sellers using third-party payment processors, factor in transaction fees when calculating discounted amounts: if you pay 3% in fees, a 2% discount would leave you with only 95% of the invoice amount if paid early.
Review your payment terms quarterly: as your cost of capital changes (e.g., you pay off a high-interest loan), adjust your discount offers to match current financial conditions.
