Invoice factoring is a financial arrangement in which a business sells its unpaid invoices to a factoring company in exchange for immediate cash. Rather than waiting for customers to pay, the business receives a percentage upfront—known as the advance rate—while the remaining balance is settled after the invoice clears. An invoice factoring calculator estimates the cash available, associated fees, and the final amount a business can expect to receive. This calculation allows companies to understand the cost of factoring with precision, making it easier to compare offers and plan working capital.
Detailed Explanations of the Calculator’s Working
An invoice factoring calculator operates by applying industry formulas to determine how much funding a business receives and what fees it must pay. First, the user enters the invoice amount and selects the advance rate, which represents the percentage provided upfront. Next, the calculator applies the daily discount rate and the number of days until payment to determine the factoring fee. Afterward, the calculator estimates the rebate, which is the portion returned to the client after deducting fees. Finally, it computes the net amount the business receives and the effective APR to analyze the true cost of factoring. This systematic process ensures clarity and transparency.
Formula With Variables Description
Formula
Advance Amount = Invoice Amount × Advance Rate (as decimal)
Factoring Fee = Invoice Amount × (1 – Advance Rate) × Daily Discount Rate (as decimal) × Number of Days Outstanding
Rebate = Invoice Amount × (1 – Advance Rate) – Factoring Fee – Other Fees
Net Amount to Client = Advance Amount + Rebate – Other Fees
Effective APR (%) = (Total Fees / Advance Amount) × (365 / Number of Days Outstanding) × 100
Variable Descriptions
- Invoice Amount: Total value of the invoice being factored.
- Advance Rate: Percentage of invoice paid upfront.
- Daily Discount Rate: Cost charged per day by the factoring company.
- Number of Days Outstanding: Estimated days until the customer pays.
- Other Fees: Processing, service, or transaction fees.
- Total Fees: All fees combined, including factoring fee and additional charges.

Example
Assume a business factors a $10,000 invoice at an 85% advance rate, with a 0.05% daily discount rate and a 45-day payment period, and $50 in other fees.
- Advance Amount = 10,000 × 0.85 = $8,500
- Factoring Fee = 10,000 × 0.15 × 0.0005 × 45 = $33.75
- Rebate = 10,000 × 0.15 − 33.75 − 50 = $1,416.25
- Net Amount to Client = 8,500 + 1,416.25 − 50 = $9,866.25
- Total Fees = 33.75 + 50 = $83.75
- Effective APR = (83.75 / 8,500) × (365 / 45) × 100 ≈ 7.97%
