Managing multiple loans can feel overwhelming—especially when deciding which debt to pay off first. The Cash Flow Index (CFI) helps borrowers and financial managers determine which loans provide the most efficient use of cash flow when making extra payments.
Our Cash Flow Index Calculator simplifies the process by letting you quickly compare debts and prioritize repayments.
What Is the Cash Flow Index?
The Cash Flow Index (CFI) is a ratio that measures how efficiently cash flow can be used to pay down a loan. It compares a loan’s outstanding balance to its monthly payment.
- High CFI → Loan is efficient and less urgent to pay off
- Low CFI → Loan consumes more cash flow and should be prioritized for early repayment
Formula
Cash Flow Index (CFI)=Loan BalanceMonthly Payment\text{Cash Flow Index (CFI)} = \frac{\text{Loan Balance}}{\text{Monthly Payment}}Cash Flow Index (CFI)=Monthly PaymentLoan Balance
Where:
- Loan Balance = remaining principal balance on the loan
- Monthly Payment = required monthly installment (principal + interest)
How the Cash Flow Index Calculator Works
- Enter Loan Balance – outstanding debt amount
- Enter Monthly Payment – required minimum monthly installment
- Click Calculate – the tool applies the formula
- View Result – higher index = less urgent, lower index = more urgent
Example Calculations
Example 1: High CFI (Low Priority)
- Loan Balance = $20,000
- Monthly Payment = $200
CFI=20,000200=100\text{CFI} = \frac{20,000}{200} = 100CFI=20020,000=100
👉 A CFI of 100 means this loan is efficient; no immediate rush to pay it down.
Example 2: Low CFI (High Priority)
- Loan Balance = $5,000
- Monthly Payment = $400
CFI=5,000400=12.5\text{CFI} = \frac{5,000}{400} = 12.5CFI=4005,000=12.5
👉 A CFI of 12.5 signals this loan consumes more cash flow, making it a high-priority target for repayment.
Why Is the Cash Flow Index Important?
