    Can a bridge loan
    fill the gap?

    Estimate available bridge proceeds and the short-term cost while you wait for your current home to sell.

    Bridge Term

    Bridge loan estimate only. Actual bridge structures vary widely by lender, including interest collection timing, reserves, fees, and how the lien is secured. Not a loan offer.

    How this calculator works

    Move the sliders to test scenarios, or tap any blue value pill to type an exact number. The headline result and supporting detail pills update live as you change inputs so you can compare options without resetting your work.

    Methodology: Bridge proceeds = max(0, current home value × max bridge LTV − current mortgage payoff). Estimated cost combines simple interest over the chosen term (proceeds × rate × months ÷ 12) plus a 1% origination-fee estimate on the bridge amount.

    Worked example: Home value $500,000, payoff $275,000, 80% max LTV, 9.5% rate, 6-month term: max loan = $400,000; bridge proceeds = $400,000 − $275,000 = $125,000; interest = $125,000 × 0.095 × 0.5 ≈ $5,938; 1% fee ≈ $1,250; estimated cost ≈ $7,188.

    Use these estimates to compare options and prepare questions for a lender. Final pricing, eligibility, and approval depend on a full application and lender review.

    How to Use Our Bridge Loan Calculator

    Use the calculator above to estimate how much a bridge loan might provide and what it could cost over a short holding period.

    Keep in mind that actual bridge loan requirements can vary significantly by lender, and qualification depends on your unique financial situation.

    Input What It Means Why It Matters
    Current home value Estimated market value of the departing home This is the starting point for available equity.
    Max bridge LTV The percentage cap used by the model This determines how much of the home’s value can support bridge financing.
    Current mortgage payoff What you still owe on the existing loan This amount is subtracted when estimating proceeds.
    Bridge rate and term The cost assumptions for the temporary loan These drive the interest estimate.

    How the Calculator Works

    A bridge loan is short-term financing designed to help you tap equity in your current home before it sells. Borrowers often use it to cover a down payment, closing costs, or other timing gaps while buying the next home.

    This calculator estimates bridge proceeds by taking the current home value, applying the maximum bridge loan-to-value ratio, and subtracting the current mortgage payoff.

    If that result is negative, the model sets the proceeds to zero.

    It then estimates the cost of the bridge loan using simple interest for the chosen term plus a 1% origination-fee estimate on the bridge amount.

    How The Cost Estimate Works

    The interest estimate is straightforward. The model multiplies bridge proceeds by the annual bridge rate and by the bridge term in months divided by 12. I

    t then adds a 1% origination fee estimate.

    This creates a fast planning estimate, not a binding quote. Actual bridge pricing can vary based on lender, property, repayment structure, and whether interest is paid monthly or deferred until payoff.

    When A Bridge Loan May Be Useful

    A bridge loan can be useful when you need access to equity before your current home sale closes. That can come into play in markets where making a non-contingent offer improves your position or where you need funds for the next down payment before sale proceeds arrive.

    It can also help when the sale and purchase timelines do not line up cleanly.

    The tradeoff is that bridge financing is usually short-term and may carry a higher rate and additional fees.

    What The Calculator Can And Cannot Tell You

    The calculator is useful for estimating the size of available proceeds and the rough carrying cost over a short term.

    It cannot confirm that a lender will approve the loan, match your final fee structure, or tell you how your primary mortgage qualification will be affected while the bridge debt is outstanding.

    The Bottom Line

    A bridge loan calculator is best used to size the transition, not just the debt. It helps you estimate whether the equity in your current home may be enough to solve the timing gap and what that short-term convenience may cost.

    Frequently Asked Questions

    How Does A Bridge Loan Work?

    A bridge loan uses equity in your current home to create short-term funds before that home sells, often to support the purchase of your next home.

    How Are Bridge Proceeds Estimated?

    The calculator applies the maximum bridge LTV to your current home value and subtracts the current mortgage payoff. The remaining amount is the estimated bridge proceeds, but never less than zero.

    What Costs Are Included?

    The model includes simple interest over the selected term and a 1% origination-fee estimate on the bridge amount.

    Are Bridge Loans Long-Term Financing?

    No. They are generally designed as short-term financing to cover a transition period between homes.
