What Is an SBA Loan?
An SBA loan is a small business loan partially guaranteed by the Small Business Administration (SBA). These loans are offered through approved lenders and are designed to help businesses access affordable financing with flexible terms.
SBA loans are commonly used for:
- Buying a business
- Purchasing commercial property
- Expanding operations
- Equipment financing
- Working capital
- Refinancing debt
Because SBA loans are partially backed by the government, lenders are often willing to offer lower interest rates and longer repayment terms compared to traditional business loans.
What Is an SBA Loan Down Payment?
A down payment is the upfront amount a borrower pays toward the purchase price of a business or asset. The remaining balance becomes the loan amount financed by the lender.
Example:
If a business costs $200,000 and the down payment requirement is 10%:
- Down Payment = $20,000
- Loan Amount = $180,000
The calculator helps determine these values automatically.

SBA Loan Down Payment Formula
The calculator uses standard loan and amortization formulas.
1. Down Payment Formula
Down Payment=Purchase Price×100Down Payment Percentage
Example:
Purchase Price = $300,000
Down Payment Percentage = 10%
Down Payment = $30,000
Loan Amount Formula
Loan Amount=Purchase Price−Down Payment
Example:
- Purchase Price = $300,000
- Down Payment = $30,000
Loan Amount = $270,000
Monthly Payment Formula
The calculator uses the standard amortized loan payment equation.
M=P×(1+r)n−1r(1+r)n
Where:
| Variable | Meaning |
|---|---|
| M | Monthly payment |
| P | Loan amount |
| r | Monthly interest rate |
| n | Total number of monthly payments |
Total Repayment Formula
Total Repayment=Monthly Payment×Total Months
SBA Loan Calculation Example
Example Scenario
| Loan Detail | Value |
|---|---|
| Purchase Price | $250,000 |
| Down Payment | 10% |
| Interest Rate | 7% |
| Loan Term | 10 Years |
Step 1: Calculate Down Payment
10% of $250,000 = $25,000
Step 2: Calculate Loan Amount
$250,000 − $25,000 = $225,000
Step 3: Estimate Monthly Payment
Using the loan payment formula:
Estimated Monthly Payment ≈ $2,613
Step 4: Total Repayment
$2,613 × 120 months = $313,560
