How to Use This Home Equity Access Calculator
This is the only calculator that compares all five home equity access methods in one place. Enter your details once and instantly see which options you qualify for, what each costs monthly, and which is best for your situation.
Quick Results
Enter your Home Value, Mortgage Balance, Amount Needed, Age, and Credit Score. The calculator shows your available equity, maximum borrowable amount, eligible options, and monthly payment for each. The Rate Environment selector triggers a critical warning if you are about to cash-out refinance away from a low existing mortgage rate.
Advanced: 5-Way Comparison Tab
The 5-Way Comparison tab shows a full side-by-side table — rate, monthly payment, upfront cost, 5-year cost, and 10-year cost — for all five methods. The Best for Your Situation tab provides a six-scenario decision framework. The Rate Environment tab explains how to choose between HELOC and cash-out refi based on where rates are today versus your existing rate.
Pro: Tax, Risk, and Optimal Strategy
The Tax Deductibility tab computes your after-tax monthly cost for each option based on your marginal tax rate and intended use. The Risk Assessment tab profiles the specific risks of each method. The Optimal Strategy tab recommends a personalized approach — including hybrid strategies combining a HELOC for flexibility with a HEL for fixed costs.
Home Equity Access Formula
Max Borrowable = Home Value × 85% − Mortgage Balance (CLTV limit)
HELOC Monthly (Interest Only) = Balance × (Annual Rate / 12)
HEL Monthly = Loan × [r(1+r)^n] / [(1+r)^n − 1], n = term months
Cash-Out Refi Monthly = (Current Balance + Cash Needed) × [r(1+r)^360] / [(1+r)^360 − 1]
Net Cash-Out Cost = New Monthly Payment − Current Monthly Payment
Equity Sharing Cost = Cash Received × (1 + Appreciation Share) at time of sale
Reverse Mortgage: Balance grows monthly = Balance × (Rate / 12), no payments required
The combined loan-to-value (CLTV) ratio is the key constraint: most lenders cap total debt secured by the home at 80-85% of appraised value. Your first mortgage balance counts against this limit, reducing how much additional equity you can access.
Example: Sandra Compares Her Equity Access Options
Scenario: Homeowner needs $60,000 for a kitchen and bathroom renovation
| Home Value | $520,000 |
| Mortgage Balance | $310,000 at 3.25% |
| Available Equity | $210,000 (40%) |
| Amount Needed | $60,000 |
| Credit Score | 750 |
| HELOC Option | 9.0% variable / $450/mo interest-only |
| HEL Option | 8.0% fixed / $728/mo over 10 years |
| Cash-Out Refi Option | 7.0% on $370,000 / $2,462/mo (up from $1,348) = +$1,114/mo |
| Sandra's Choice | HELOC — preserves her 3.25% first mortgage |
| Tax Benefit (24% bracket) | Interest deductible since used for home improvement |
Sandra chose the HELOC because replacing her 3.25% mortgage with a 7% cash-out refi would have cost an extra $1,114 per month — far more than the HELOC interest on $60,000. She also benefits from the mortgage interest deduction since the funds are for home improvement.
