Example:
If a company pays $500,000 in interest on $10,000,000 in loans:
Cost of Funds = ($500,000 / $10,000,000) × 100 = 5%

💼 Why Cost of Funds Is Important
Understanding your cost of funds is crucial for various reasons:
- Profitability Analysis: Higher cost of funds reduces net profits.
- Loan Comparisons: Helps in comparing different financing options.
- Investment Decisions: Used to evaluate if a project yields more than it costs to finance.
- Banking Sector: Financial institutions use cost of funds to set interest rates on loans and credit products.

🧪 Example Calculation
Let’s say your company pays:
- Interest Expense: $75,000
- Total Debt: $1,250,000
Cost of Funds = (75,000 / 1,250,000) × 100 = 6%
This means your business is effectively paying 6% per year to borrow funds.
