How It Works

Qualifying Income Formula

Qualifying Income = Average Monthly Deposits × (1 - Expense Factor)

The expense factor represents the percentage of deposits assumed to be business expenses. A 50% expense factor means half of deposits are treated as qualifying income.

Expense Factors by Business Type

Different industries have different typical expense ratios:

Business TypeExpense FactorIncome Factor
Service-Based50%50%
Retail/Product-Based60%40%
Real Estate/Construction65%35%
Medical/Professional50%50%

Affordability Estimate

Monthly Debt Capacity = Monthly Qualifying Income × Max DTI

Max Loan = PV(Monthly Debt Capacity, Rate, Term)

The affordability estimate uses standard present value calculations to determine the maximum loan amount based on qualifying income and debt-to-income limits.

Example Scenario

A freelance consultant with average monthly deposits of $15,000 seeking a bank statement loan.

Inputs

Calculation Period12 months
Business TypeService-Based
Expense Factor50%
Avg Monthly Deposits$15,000
Max DTI43%
Estimated Rate8.5%

Results

Total Deposits$180,000
Monthly Qualifying Income$7,500
Annual Qualifying Income$90,000
Max Monthly Payment$3,225
Est. Max Loan Amount~$438,000

Explanation

With $15,000 average monthly deposits and a 50% expense factor, the qualifying income is $7,500/month ($90,000/year). At a 43% DTI, this supports a maximum payment of $3,225, which translates to approximately $438,000 in loan amount at 8.5% over 30 years.
