Important Disclosure
Rates shown are for illustration only. Actual APRs, fees, and repayment terms vary by lender and are determined based on your creditworthiness, loan-to-value ratio, and other factors. A HELOC typically carries a variable interest rate that adjusts with the prime rate; your rate and monthly payment may increase over the life of the loan.
The estimates provided by this calculator are not a loan offer, pre-approval, or commitment to lend. Results do not include all costs associated with obtaining a HELOC, such as closing costs, appraisal fees, annual fees, or third-party charges.

Why Choose a First Lien HELOC?
A smarter way to manage your home financing that puts your money to work.
Potentially Pay Less Interest
Simple interest calculated daily on your declining balance instead of amortized over 30 years. Actual savings depend on your rate, balance, and payment behavior.
Flexible Payments
Use your checking deposits to reduce your principal daily, then draw funds when needed.
Revolving Credit
Access your equity anytime without refinancing. It works like a giant checking account secured by your home.
First Lien Position
Replaces your primary mortgage entirely — not a second lien. Same priority, more flexibility.
A HELOC typically carries a variable interest rate tied to the prime rate. Your rate, monthly payment, and total interest paid may increase over the life of the loan. Results shown are estimates for educational purposes only and do not constitute a loan offer. See full disclaimer.
What Is a First Lien HELOC & How It Works
A first lien HELOC replaces your primary mortgage with a home equity line of credit in the senior lien position. This makes your entire home loan a revolving credit line — giving you the power to reduce interest costs through daily principal reductions.
Replace Your Mortgage with a 1st‑Lien HELOC
A first lien HELOC becomes the primary loan secured by your home, replacing a traditional amortized mortgage. Instead of a rigid schedule, your loan works like a large checking account.
- Interest is calculated on the daily balance, not a fixed amortization schedule.
- You can pay any amount, any day, and it immediately reduces interest.
- You retain full liquidity because you can re‑borrow if needed.
This sets the stage for using targeted payments instead of full cash‑flow cycling.
Choose a Targeted Monthly Payment
Instead of routing all income through the HELOC, you set a strategic monthly payment that exceeds your original mortgage payment based on your comfort level.
- Predictable and sustainable over the long term.
- Larger than what a traditional mortgage would require at the same balance.
- Even modest extra principal payments create outsized impact with daily interest.
Because the HELOC calculates interest daily, each extra dollar paid works harder than it would on a fixed mortgage.
Accelerate Principal Paydown
Your fixed payment amount (net of the minimum interest‑only payment) goes straight toward reducing the HELOC balance. Every dollar above the minimum is pure principal reduction.
- Minimum payment covers interest only.
- Your chosen extra amount reduces principal directly.
- Lower principal reduces next month's interest charge.
- Compounding savings accelerate payoff over time.
You get the benefit of velocity banking without moving your entire financial life into the HELOC.
Reassess & Increase Over Time
Because a first lien HELOC is flexible, you can adjust your payment strategy as your financial situation evolves:
- Increase the fixed payment as income grows.
- Add occasional lump‑sum payments (bonuses, tax refunds).
- Keep liquidity — you can re‑borrow if needed.
Many homeowners may shave 5–10 years off a 30-year mortgage using this approach, though individual results vary based on rates, income, and payment discipline.
