Business Loan Calculator & Formula

Business Loan Calculator








The monthly payment formula helps determine a fixed payment amount based on the loan principal, interest rate, and term. This calculation includes both the principal and interest components, allowing business owners to understand their monthly cash flow commitment.

Business Loan Formula

The formula to calculate the monthly payment for a business loan is:


Monthly Payment = P × r × ( 1 + r ) n ( 1 + r ) n 1

Where:

  • P: Loan Amount
  • r: Monthly interest rate (annual rate / 12)
  • n: Total number of payments (loan term in years × 12)

Real-Life Example

Let’s say a business owner takes a loan with the following terms:

  • Loan Amount (P): $50,000
  • Annual Interest Rate: 5%
  • Loan Term: 10 years

Step 1: Convert the annual interest rate to a monthly rate:
Monthly Interest Rate (r) = 5% / 12 = 0.004167

Step 2: Calculate the total number of payments:
n = 10 years × 12 = 120 payments

Step 3: Apply the formula:

Monthly Payment = (50000 × 0.004167 × (1 + 0.004167)^120) / ((1 + 0.004167)^120 – 1) ≈ $530.33

In this example, the monthly payment would be $530.33.

Benchmark Indicators

Typical loan term and interest rate benchmarks help assess loan affordability:

Low Rate: 3% – 6% – Common for high-credit borrowers

Average Rate: 7% – 15% – Standard for business loans

High Rate: Above 15% – Typical for riskier loans or short terms
