Rate Sensitivity Analysis

HELOCs have variable rates. Your payment may increase if rates rise.

Scenario	Rate	Interest Only	Full Payment	Increase
Current Rate	9.00%	-	-	-
+1% rate increase	10.00%	$333.33	$386.01	+$26.12(7.3%)
+2% rate increase	11.00%	$366.67	$412.88	+$52.98(14.7%)
+4% rate increase	13.00%	$433.33	$468.63	+$108.74(30.2%)

Understanding HELOCs

Two-Phase Structure

Draw Period (5-10 years): Borrow as needed, pay interest only.

Repayment Period (10-20 years): No new draws, full amortization.

Variable Rate Risk

HELOC rates are typically tied to Prime Rate. If Prime rises, your payment increases. Budget for rate increases and consider the rate sensitivity analysis.

HELOC vs HEL

- HELOC: Revolving credit, variable rate
- HEL: Lump sum, fixed rate
- HELOC: Flexible access to funds
- HEL: Predictable payments

Best Uses for HELOC

- Ongoing projects with variable costs
- Emergency fund backup
- Business expenses
- Education costs over time
