The True Cost of a HELOC in 2025
HELOC total interest cost at 9% over 10-year interest-only period (2025 estimated rates)
| HELOC Amount | Rate | 10-Year Total Interest | Monthly Interest-Only Payment |
|---|---|---|---|
| $30,000 | 9.0% | $27,000 (if held 10 years) | $225/month |
| $50,000 | 9.0% | $45,000 | $375/month |
| $75,000 | 9.0% | $67,500 | $562/month |
| $100,000 | 9.0% | $90,000 | $750/month |
⚠️The HELOC End-of-Draw Risk
After the 10-year draw period, HELOC payments convert to fully amortizing repayment over the remaining term (typically 15–20 years). A $75,000 HELOC balance at 9% entering repayment phase: $756/month. Many homeowners are surprised by this 'payment shock.' Understand the repayment phase before opening a HELOC.
When a HELOC Makes Clear Financial Sense
- Home renovations with ROI above HELOC rate: Kitchen at 9% HELOC, adds 115% value = positive net equity outcome
- Bridging for another home purchase: Draw HELOC → buy new home → sell old home → repay HELOC. Avoids contingency offers in competitive markets
- Business working capital at lower cost than business credit: HELOC at 9% vs. business line at 14–18% = meaningful savings for established businesses
- Investment property down payment: Draw HELOC → purchase property yielding 10%+ → net positive carry
When a HELOC Is the Wrong Tool
- Funding consumer lifestyle: Vacations, cars, clothing — zero-return uses of high-cost capital
- Volatile investments: Borrowing at 9% to invest in individual stocks or crypto is a mathematically weak bet
- Emergency fund substitute: HELOCs can be frozen at the worst time — keep a liquid emergency fund separately
- Debt consolidation without behavior change: Consolidating credit cards via HELOC and then running the cards back up doubles the problem
