Americans Are Sitting on $32 Trillion in Home Equity
With average home equity exceeding $300,000 for homeowners who bought more than 5 years ago, the decision between a home equity loan and a HELOC is increasingly relevant. Both let you tap that equity, but they have fundamentally different structures — and choosing the wrong one for your need can cost thousands in unnecessary interest.
How Each Product Works
Home Equity Loan
- Fixed lump sum disbursed upfront
- Fixed interest rate
- Fixed monthly payment over set term (typically 5–30 years)
- Rate: typically 0.5–1% higher than HELOC initial rate
- Best for: known, one-time expenses (renovation, debt consolidation, major purchase)
HELOC (Home Equity Line of Credit)
- Revolving credit line, draw as needed
- Variable rate (typically Prime + margin)
- Draw period: typically 10 years (interest-only payments optional)
- Repayment period: typically 20 years (fully amortizing)
- Rate: typically lower initially, but variable
- Best for: ongoing expenses, emergencies, projects with uncertain total cost
Calculating How Much You Can Borrow
Lenders typically allow a combined loan-to-value (CLTV) of 80–85%:
Max borrowing = (Home Value × 0.85) − Remaining Mortgage Balance
Example: Home worth $550,000, remaining mortgage $320,000:
Max HELOC/HEL = ($550,000 × 0.85) − $320,000 = $467,500 − $320,000 = $147,500
Total Cost Comparison: Home Equity Loan vs. HELOC
Borrowing $60,000 for a kitchen renovation (all at once):
| Feature | Home Equity Loan | HELOC (variable) |
|---|---|---|
| Rate | 7.5% fixed | 7.0% initial (Prime+1.75%) |
| Term | 10 years | 10yr draw + 20yr repay |
| Monthly payment (P&I) | $713 | $350 interest-only in draw |
| Total interest (rate stays flat) | $25,560 | ~$42,000 (draw + repayment) |
| Predictability | High | Low (rate varies) |
The HELOC's lower initial payment is misleading — if you only pay interest during the draw period, you've paid $42,000 in interest by the end of the 30-year combined term vs. $25,560 with the home equity loan over 10 years. For a lump-sum need, the home equity loan typically wins on total cost.
When the HELOC Wins
Scenario: Ongoing home renovation over 3 years, drawing an average of $2,500/month = $90,000 total, but spread over time.
- With a home equity loan: you'd take $90,000 upfront and pay interest on all of it from day one
- With a HELOC: you pay interest only on what's drawn — average balance over 3 years might be $45,000
- Interest savings: substantial — potentially $7,000–$12,000 less in total interest if you'd drawn incrementally
The HELOC also shines for emergency funds: $50,000 line sitting unused costs nothing. The home equity loan starts charging the moment it's funded.
Rate Risk: What Happens if Prime Rises 2%?
If you have a $80,000 HELOC at Prime + 1.75% and Prime rises from 7.5% to 9.5%:
- Initial rate: 9.25% → payment: $616/month (interest-only on full balance)
- After 2% increase: 11.25% → payment: $750/month
- Additional annual interest cost: $1,608
Rate caps matter: most HELOCs have periodic caps of 2% per adjustment and lifetime caps of 5–6% above initial rate. Always calculate your payment at the lifetime maximum rate.
Tax Deductibility
Interest on home equity loans and HELOCs is tax-deductible only if the funds are used to buy, build, or substantially improve the secured home (post-2017 tax law). Used for debt consolidation, vacation, or car purchase: not deductible. Used for a kitchen renovation: deductible on up to $750,000 of combined mortgage debt for married filers.
Bottom Line
For a specific, one-time expense: home equity loan wins on predictability and often total cost. For ongoing needs, emergencies, or phased projects: HELOC wins on flexibility and potentially lower total interest if drawn incrementally.
