How to Use the Small Business Loan Calculator
Using the Small Business Loan Calculator is simple. You only need a few pieces of information to get started:
- Loan Amount – Enter the amount you plan to borrow from the lender.
- Interest Rate (%) – Input the annual interest rate offered by the lender.
- Loan Term (Years or Months) – Specify how long you plan to repay the loan.
- Click Calculate – The tool will instantly display your monthly payment amount, total interest paid, and the total loan cost.
Formula Used in the Calculator
The calculator uses the standard loan amortization formula:
Monthly Payment = [P × r × (1 + r)^n] ÷ [(1 + r)^n – 1]
Where:
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate divided by 12)
- n = Total number of monthly payments (term in years × 12)
This formula ensures an accurate breakdown of how much you will pay each month.
Example Calculation
Let’s say you are borrowing $50,000 for your business with an annual interest rate of 6% for 5 years.
- Loan Amount (P) = $50,000
- Annual Interest Rate = 6% → Monthly Rate = 0.06 ÷ 12 = 0.005
- Loan Term = 5 years → Total Months = 5 × 12 = 60
Monthly Payment = [50,000 × 0.005 × (1 + 0.005)^60] ÷ [(1 + 0.005)^60 – 1]
Monthly Payment ≈ $966.64
- Total Interest Paid = $966.64 × 60 – $50,000 = $7,998.40
- Total Loan Cost = $50,000 + $7,998.40 = $57,998.40
With this information, you can see exactly what the loan will cost over its entire term.
