Quick Summary Grid
Home Value: Current market value of your property
Total Debt: Sum of all mortgages and home loans

Available to Borrow: How much you could potentially borrow against your home
- Based on 80% Combined Loan-to-Value (CLTV) ratio
- This is additional borrowing capacity
Loan-to-Value Ratio (LTV)
Shows what percentage of your home's value is financed by debt:
| LTV Range | Status | Meaning |
|---|---|---|
| ≤ 80% | ✓ Excellent | Good borrowing capacity, best rates |
| 81-90% | ⚠ Moderate | Limited borrowing, higher rates |

Key Concepts Explained
Home Equity
The portion of your home that you truly own, free and clear.
- Example: $400k home - $250k mortgage = $150k equity
Loan-to-Value (LTV) Ratio
Percentage of a home's value that's financed by loans.
- Formula: (Total Debt ÷ Home Value) × 100
- Example: $250k debt ÷ $500k value = 50% LTV
Combined Loan-to-Value (CLTV)
Includes ALL loans secured by the property (1st mortgage + HELOC + 2nd mortgage).
- Most lenders limit CLTV to 80-85%
Available to Borrow
How much additional credit can you access based on your equity?
- Formula: (Home Value × 80%) - Current Debt
- Example: ($500k × 80%) - $250k = $150k available
Appreciation/Depreciation
Change in home value since purchase.
- Appreciation: Home gained value (positive)
- Depreciation: Home lost value (negative)
What Can You Do With Home Equity?
1. Home Equity Loan (Second Mortgage)
- Lump sum payment
- Fixed interest rate
- Fixed monthly payment
- Good for: One-time expenses (renovations, debt consolidation)
2. Home Equity Line of Credit (HELOC)
- Revolving credit line
- Variable interest rate
- Draw as needed
- Good for: Ongoing expenses, emergencies
3. Cash-Out Refinance
- Replace the existing mortgage with a larger one
- Take the difference in cash
- New interest rate and terms
- Good for: Large amounts, debt consolidation
4. Reverse Mortgage (Age 62+)
- Convert equity to income
- No monthly payments
- Repaid when the home is sold
- Good for: Retirement income
Borrowing Guidelines
How Much Can You Borrow?
Most lenders allow:
- 80% CLTV (Conservative, best rates)
- 85% CLTV (Common for HELOCs)
- 90% CLTV (Higher rates, limited options)
This calculator uses 80% CLTV for the "Available to Borrow" calculation.
Example:
- Home Value: $400,000
- Max Borrowing (80%): $320,000
- Current Debt: $200,000
- Available: $120,000
Important Considerations
Factors Affecting Home Value:
📍 Location: Neighborhood trends, school districts, development 🏗️ Market Conditions: Supply/demand, interest rates, economy 🔧 Home Condition: Upgrades, maintenance, age 📏 Size & Features: Square footage, bedrooms, amenities
Risks of Borrowing Against Equity:
⚠️ Foreclosure Risk: Home is collateral - can lose it if you default ⚠️ Declining Value: Market downturn can leave you underwater ⚠️ Interest Costs: Borrowing costs money over time ⚠️ Closing Costs: Fees for new loans (typically 2-5%)
When to Tap Home Equity:
✅ Home improvements that add value ✅ Debt consolidation at lower rates ✅ Education expenses (tax-deductible in some cases) ✅ Emergency expenses
When NOT to Tap Equity:
❌ Vacations or luxury purchases ❌ Depreciating assets (cars, boats) ❌ Speculative investments ❌ If you can't afford payments
Tips for Building Equity Faster
- Make Extra Principal Payments: Even small amounts help
- Bi-Weekly Payments: Results in one extra payment per year
- Home Improvements: Kitchen/bath upgrades add the most value
- Refinance to Shorter Term: 30-year to 15-year mortgage
- Avoid HELOCs for Non-Essentials: Don't erode equity needlessly
- Maintain Your Home: Prevents value depreciation
Equity Benchmarks by Home Age
| Time Owned | Typical Equity |
|---|---|
| 1-5 years | 10-20% |
| 5-10 years | 20-40% |
| 10-15 years | 40-60% |
| 15-20 years | 60-80% |
| 20-30 years | 80-100% |
Assumes standard 30-year mortgage with appreciation
Important Notes
⚠️ Home Value Accuracy: This calculator is only as accurate as the home value you enter. Consider:
- Professional appraisal ($300-500)
- Comparative Market Analysis (CMA) from a realtor
- Online estimates (Zillow, Redfin) - use with caution
⚠️ Tax Implications:
- Mortgage interest may be tax-deductible
- HELOC interest may be deductible for home improvements
- Consult a tax professional
⚠️ 80% CLTV Assumption: The "Available to Borrow" uses 80% CLTV. Some lenders offer terms of 85% or higher, but the terms vary.
