Formulas Used

  • Combined LTV: (Mortgage + Borrow) ÷ Home value × 100.
  • Interest-only payment: Balance × (Rate ÷ 12).
  • Installment payment: P × r × (1+r)n ÷ ((1+r)n − 1).
  • Total interest: Sum of monthly interest across the schedule.
  • Estimated APR: Rate that matches net proceeds to discounted payments.

Cost Structure Comparison

A credit line commonly starts with lower required payments because early payments are mostly interest, while a fixed loan immediately amortizes principal. In many lender quotes, upfront costs range from a few hundred to a few thousand dollars, so fees can change the effective cost even when rates look similar. This page also estimates APR by discounting payments against net proceeds.

Payment Path and Cash Flow

This calculator models an interest-only draw period and then a repayment period that amortizes the ending balance. For a fixed loan, the payment is stable each month, which helps with budgeting and debt-to-income planning. If you borrow $50,000 for 15 years at 8.75%, the payment is about $496 monthly, before fees. Over the first year, that is roughly $5,950 in payments.

Rate Risk and Stress Testing

Variable pricing can move quickly. A 1.00 percentage-point increase on a $50,000 balance adds about $41.67 per month of interest-only cost. Stress testing a higher cap rate shows how payment volatility can strain cash flow, even if the average rate ends up moderate across the full horizon. A gradual draw can reduce early interest, but totals depend on timing.

Equity Limits and LTV Discipline

Lenders often limit combined loan-to-value. If your home is $350,000 and your first mortgage is $220,000, an 85% limit allows total debt up to $297,500. That leaves roughly $77,500 of available room, so a larger request may be rejected or priced differently. Lower LTV can also improve pricing and approval odds.

Decision Framework and Next Steps

Choose flexibility when spending is uncertain and you can manage rate swings. Choose predictability when you want a fixed payoff schedule and stable total-cost expectations. Compare total paid, total interest, and estimated APR with fees, then confirm real offers, payment rules, and tax treatment with a qualified professional. Keep a buffer for escrow, insurance, and emergency expenses.

FAQs

1) What is the main difference between a credit line and a fixed equity loan?

A credit line lets you borrow, repay, and borrow again during the draw period, usually with variable pricing. A fixed equity loan gives one lump sum with a fixed rate and a fixed amortizing payment schedule.

2) How does the calculator estimate HELOC payments during the draw period?

It assumes interest-only payments on the outstanding balance and can model either a full draw at start or a gradual ramp. It also spreads any annual fee into monthly equivalents for a cleaner comparison.

3) Why does the tool show an estimated APR for both options?

APR reflects fees by comparing net proceeds to discounted monthly payments. It helps you compare offers where one option has lower rates but higher closing costs or points.

4) What inputs affect my available equity the most?

Home value, current mortgage balance, and the combined loan-to-value limit drive available room. A higher LTV limit usually increases capacity, while a higher existing mortgage reduces it.

5) When might a fixed equity loan be a better fit?

It can be better when you need the full amount immediately and want a stable payment, especially if you prefer predictable budgeting and plan to keep the loan for most of the term.

6) Is this calculator financial advice or a lender quote?

No. It uses simplified assumptions and generalized fee handling. Actual pricing, caps, repayment rules, and eligibility vary by lender and location, so confirm details before making a commitment.

Important: This tool uses simplified assumptions. Rates, fees, and payment rules vary by lender and region. Consider professional guidance for a final decision.
