About Borrowing Power Calculator
The Borrowing Power Calculator determines the maximum total loan amount you can safely borrow without overextending your monthly cash flow, based on net income and responsible debt service ratios.
Formula & Mathematical Calculation
Max Monthly Debt Budget = ( Net Monthly Income - Living Expenses ) × 0.60
Max Borrowing Power = Max Monthly Debt Budget × [ (1 + r)^n - 1 ] / [ r(1 + r)^n ]
Calculation Example
Example: $6,000/mo income, $3,500/mo essential expenses → Available surplus = $2,500/mo ($1,500 debt budget). At 8% APR for 5 years → Borrowing Capacity = $73,982.
