What would affect the monthly payment on a $1 million business loan?

Not all loans are structured the same. Key variables include:

  • Loan types and structures
    • Fully Amortized Term Loan
    • One-time interest-only loan
    • floating rate loan
    • income-based financing
  • interest rate
    • Even a 1-2% difference can change the total cost by tens of thousands of dollars.
  • Fees and closing costs

Other loan costs to consider

When assessing the true cost of a loan, make sure you consider fees beyond the base interest rate.

  • Origination fee
    • Typically 1%–5% of the loan amount.
    • Example: 1% fee on $1,000,000 = $10,000
  • Prepayment penalty
    • Not all lenders charge them a fee, but some do, especially traditional banks.
  • Additional loan fees
    • These may include underwriting fees, packaging fees or annual review fees.
    • Be sure to ask for a complete breakdown of costs before signing the loan documents.

Understanding Amortization: Why Your Monthly Payment Looks Like This

When you apply for a fixed-rate business loan, your monthly payments remain the same, but your payment options change over time. This is amortization.

  • Loan initial stage: Most of the payment goes toward interest.
  • Later on when taking out a loan: As the interest portion decreases, more money flows toward the principal.

For large business loans, amortization provides:

  • Predictable monthly payments
  • Better budgeting and cash flow planning
  • Clear visibility of debt reduction over time

Using an amortization schedule (or our business loan calculator) can help you understand exactly how quickly you’ll pay down your debt.

What Lenders Look for in a $1 Million Business Loan Application

When you apply for a business loan or any large business financing, lenders will be looking for:

  1. strong annual revenue – Consistent, reliable income is one of the biggest factors in approval for this loan size.
  2. Good personal and business credit – While smaller loans may allow for lower credit scores, million-dollar loans typically require FICO 630-720+.
  3. Proven financial management – A record of successfully handling large amounts of capital (e.g., $2 million+ in lifetime financing) builds lender confidence.
  4. The purpose of funds is clear – You need a detailed strategic plan on how to invest the $1 million into the business.
  5. Industry and regional specifics – Industries such as manufacturing, construction, transportation, wholesale distribution and logistics are generally more likely to qualify due to their strong asset base and cash flow model.
