About the SBA 504 Calculator

The SBA 504 Calculator is explicitly designed for entrepreneurs purchasing commercial real estate or heavy machinery. Because 504 loans use a unique multi-lender structure, standard loan calculators cannot accurately estimate your capital stack or down payment requirements.

How the Calculator Works

You enter the total project cost of the real estate or equipment you wish to purchase. The calculator then models the standard 50/40/10 split: determining exactly how much the primary bank will fund (50%), how much the CDC/SBA will fund via a secondary mortgage (40%), and what your required cash down payment will be (10%).

The 50/40/10 Structure of an SBA 504 Loan

The SBA 504 loan program is the gold standard for purchasing commercial real estate or heavy equipment. It features a unique three-part structure designed to minimize the borrower's down payment:

When is a 15% or 20% Down Payment Required?

While 10% is the standard down payment, it increases by 5% if the business is a startup (under 2 years old) OR if the property is considered "special purpose" (e.g., a gas station or hotel). If both conditions apply, a 20% down payment is required.

CDC Fees vs. Bank Fees

504 loans have slightly higher upfront fees than standard bank loans because two lenders are involved. The CDC loan includes an SBA Guaranty Fee (0.5%), a CDC Processing Fee (1.5%), and a Funding Fee. Fortunately, these are financed into the CDC portion of the loan.

Understanding the 10-Year Prepayment Penalty

The SBA 504 loan has a strict, declining prepayment penalty for the first 10 years of the 25-year term. It starts at a high percentage and decreases by 10% each year until it disappears in year 11. You should not take a 504 loan if you plan to flip or sell the property quickly.
