How the Calculator Works
The calculator uses financial formulas and lending rules:
1. Home Equity
Home Value − First Mortgage
2. Maximum Second Mortgage
Up to 80% of home value minus first mortgage
3. Approved Amount
Minimum of desired amount and maximum allowed
4. Monthly Payment
Calculated using interest rate and loan term
5. CLTV Ratio (Combined Loan-to-Value)
(First Mortgage + Second Mortgage) ÷ Home Value
6. Loan Status Logic
- CLTV ≤ 80% → Approved
- CLTV ≤ 85% → Conditional Approval
- No equity → Not Approved
Why Home Equity Matters
Home equity is the portion of your home that you truly own. The more equity you have, the more you can borrow.
Example:
- Home Value: $300,000
- Mortgage Balance: $200,000
- Equity: $100,000
Higher equity increases approval chances and borrowing power.
