Understanding Bridge Loans

A bridge loan is a form of short-term financing that helps borrowers "bridge the gap" between two financial events. Most commonly used in real estate, bridge loans provide quick access to capital while you wait for a longer-term financing solution or the sale of an existing property. Our bridge loan calculator helps you estimate the monthly payments and total costs so you can make an informed decision about whether this type of financing is right for your situation.

What Is a Bridge Loan?

A bridge loan is a temporary loan, typically lasting between 6 and 12 months, that provides immediate funds when timing is critical. In real estate, the most common scenario involves a homeowner who wants to purchase a new property before selling their current one. The bridge loan allows them to access the equity in their existing home to fund the down payment on the new property. Once the old home sells, the proceeds are used to repay the bridge loan in full. Bridge loans are also used by real estate investors who need to close quickly on a property and plan to refinance into a permanent mortgage or sell the property for a profit within a short timeframe.

When to Use a Bridge Loan

Bridge loans make sense in situations where speed and flexibility matter more than cost. If you find your dream home but have not yet sold your current one, a bridge loan can provide the funds you need to make a competitive offer without a home-sale contingency. Real estate investors often use bridge loans to acquire properties at auction or through distressed sales where conventional financing would take too long to arrange. Business owners may also use bridge loans to cover cash flow gaps while waiting for receivables, inventory sales, or long-term funding to come through. In every case, the key characteristic is that the borrower has a clear exit strategy and expects to repay the loan within a short period.

How Bridge Loans Work

Bridge loans are typically structured as interest-only loans, meaning the borrower pays only the interest each month and repays the full principal at the end of the term. This keeps monthly payments lower during the loan period, which can be helpful if you are simultaneously carrying a mortgage on your existing property. Some bridge loans are fully amortizing, where each payment covers both principal and interest. The loan-to-value ratio is usually limited to 70% to 80% of the property's appraised value, and lenders generally require a credit score of 680 or higher. Closing costs and origination fees tend to be higher than conventional loans, often ranging from 2% to 5% of the loan amount.

Costs and Risks of Bridge Loans

Bridge loans come with higher interest rates than conventional mortgages, typically ranging from 8% to 12% or more. Origination fees, appraisal costs, and closing costs add to the overall expense. The primary risk is that your exit strategy may not materialize on schedule. If your existing home does not sell as quickly as expected, or if your permanent financing falls through, you could be stuck making higher payments for longer than anticipated. Some bridge loans include extension options, but these usually come with additional fees. Borrowers should have a backup plan, such as the ability to convert the bridge loan into a longer-term loan, in case the original timeline slips.

Bridge Loan vs Hard Money Loan

Bridge loans and hard money loans are both short-term, higher-rate financing options, but they serve different purposes and come from different types of lenders. Bridge loans are typically offered by banks and traditional lenders and are often used by homeowners in transition. Hard money loans come from private investors or companies and are primarily used for investment properties, fix-and-flip projects, and situations where the borrower may not qualify for traditional financing. Bridge loans generally have lower rates than hard money loans but stricter qualification requirements.

Worked Example: $200,000 Bridge Loan at 9.5% Over 12 Months

This walkthrough uses the bridge loan calculator's default inputs. Bridge loans are structured as interest-only with a balloon payoff of the original principal at the end of the term — fundamentally different from a standard amortizing loan.

Step 1 — Compute the monthly interest-only payment

The annual rate 9.5% applied to the $200,000 principal, divided by 12:

$200,000 × 0.095 ÷ 12 = $1,583.33 / month

Every monthly payment is pure interest — the principal balance never decreases.

Step 2 — Compute the balloon payment at month 12

At the end of the 12-month term, you owe the final interest payment plus the entire original principal:

Balloon = $1,583.33 (final interest) + $200,000 (principal) = $201,583.33

Step 3 — Total cost of the bridge

12 monthly interest payments of $1,583.33 = $19,000 in interest. Add the $200,000 principal repayment and the borrower pays out $219,000 in total over the year, of which $19,000 is interest cost.

Step 4 — Verify in Excel or Google Sheets

Bridge loan math is a simple interest calculation, not an amortization formula:

=200000*0.095/12 → $1,583.33 (monthly interest)

Assumptions & limitations

• Interest-only structure with balloon payoff of original principal. This is the dominant bridge loan structure; some lenders offer amortizing bridge loans, which our mortgage calculator handles instead.
• Origination fees (typically 2–5%) and closing costs are excluded. A 2-point origination fee on $200,000 adds $4,000 upfront.
• Rate is fixed for the full term. Variable-rate bridge loans exist but are uncommon.
• Exit strategy (sale of prior home, refinance to permanent mortgage) is assumed to execute exactly at month 12. Delays accrue additional monthly interest and may trigger extension fees.
• No prepayment penalty modeled. Most bridge loans allow early payoff, which reduces total interest paid.

Sources & Editorial Standards

Bridge loans accrue simple interest monthly on the original principal, with the principal due as a lump-sum balloon at maturity. our bridge loan calculator exposes this structure directly — there is no amortization formula involved, because the principal never amortizes. Compare this to our hard money calculator, which uses identical math for a different borrower profile.
