SBA Mortgage Formula Explained
The calculator uses the standard amortization loan formula to estimate monthly payments.
Mortgage Payment Formula
M=P×(1+r)n−1r(1+r)n
Formula Variables
| Symbol | Meaning |
|---|---|
| M | Monthly payment |
| P | Principal loan amount |
| r | Monthly interest rate |
| n | Total number of monthly payments |
How the Formula Works
The formula calculates equal monthly payments over the life of the loan while accounting for compound interest.
The calculator automatically:
- Converts annual interest to monthly interest
- Calculates total months
- Applies amortization formula
- Determines monthly repayment amount
SBA Mortgage Calculation Example
Example Scenario
| Loan Detail | Value |
|---|---|
| Property Price | $500,000 |
| Down Payment | $100,000 |
| Financed Amount | $400,000 |
| Interest Rate | 6% |
| Loan Term | 20 Years |
Step 1: Determine Financed Amount
Formula
Financed Amount=Loan Amount−Down Payment
Calculation:
$500,000 − $100,000 = $400,000
Step 2: Calculate Monthly Payment
Estimated monthly payment:
≈ $2,866
Step 3: Total Repayment
$2,866 × 240 months = $687,840
Step 4: Total Interest Paid
$687,840 − $400,000 = $287,840

Factors That Affect SBA Mortgage Payments
Several elements impact your monthly repayment amount.
1. Loan Amount
Higher loan amounts increase monthly payments and total interest.
2. Interest Rate
Even a small rate increase can significantly affect total repayment costs.
Example:

- 8% interest = much higher repayment
3. Loan Term
Longer loan terms reduce monthly payments but increase total interest.
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 10 Years | Higher | Lower |
| 20 Years | Moderate | Higher |
| 25 Years | Lower | Highest |
4. Down Payment
A larger down payment reduces:
- Financed amount
- Monthly payments
- Total interest
