How This Calculator Works
Enter the bridge loan amount, the APR, and the term. The calculator turns the rate into one constant monthly payment using the amortization formula and shows total interest. Many real bridge loans run interest-only with a balloon at payoff — pick the structure that matches your contract.
The Formula
Fixed-Rate Amortization
P = loan amount, r = monthly rate (APR ÷ 12), n = number of monthly payments
Worked Example
A $300,000 bridge loan at 10% APR over 1 year produces a monthly payment of about $26,375 — large, because the loan repays the full principal inside a year. Total interest comes to roughly $16,500 across the term.
Key Insight
Bridge loans cost more than conventional mortgages because they are fast, short-term, and secured against transitional equity. The breakeven question is rarely 'what is the rate' — it is 'is the new home worth losing if the timing slips by a month'. Underwrite for the timing risk, then check the rate.
When bridge loans make sense — and when not
Bridge loans serve real but narrow purpose: providing capital between two known financing events. Common appropriate use: (1) RESIDENTIAL REAL ESTATE — homeowner has identified next home, needs to close before selling current home. Bridge loan against current home pays new home; existing home sells; proceeds pay off bridge.
(2) COMMERCIAL REAL ESTATE — investor buying property needing renovation; bridge loan funds purchase + rehab; refinance to permanent loan after stabilization. (3) BUSINESS ACQUISITION — bridge financing for business purchase while permanent financing is processed. (4) IPO / LIQUIDITY BRIDGE — pre-IPO companies sometimes bridge to expected IPO proceeds.
Bridge loans are INAPPROPRIATE for: (1) Long-term financing needs (rate is too high, term too short); (2) Speculative bets on rate movements ('rate will drop, bridge until then'); (3) Borrowers without clear permanent financing identified; (4) Real estate without strong sale catalyst (assumes property will sell quickly — often doesn't in slow markets).
Bridge loan exit risk
Bridge loan's defining feature is short term (6-24 months). At term end: full balance is due. Borrower has three options: (1) PERMANENT FINANCING — replace bridge with longer-term loan. Requires qualifying for permanent financing at terms acceptable to borrower. (2) ASSET SALE — sell the property/asset and pay off bridge from proceeds.
(3) EXTEND BRIDGE — many lenders offer extensions (typically 3-12 months) at higher rate. Useful temporary measure but extends high-cost financing.
Risk: failure to execute on exit creates serious problem. If permanent financing falls through (appraisal low, rate environment shifted), borrower may face: (a) forced sale at unfavorable terms, (b) extension at much higher rate, (c) default and lender taking the property. Always have multiple exit paths planned before taking bridge loan.
Bridge loan typical terms (2024)
Reference bridge loan terms by purpose and source.
| Purpose / Source | APR | Term | Origination fee |
|---|---|---|---|
| Residential bridge (home-to-home) | 8-12% | 6-12 months | 1-3% |
| Commercial real estate bridge | 9-13% | 12-24 months | 1-3% |
| Commercial bridge to permanent | 10-14% | 12-24 months | 1-2% |
| Hard money bridge (real estate) | 10-15% | 6-18 months | 2-5% |
| Business acquisition bridge | 9-13% | 12-24 months | 1-3% |
| Asset-based bridge | 10-14% | 12-24 months | 1-2% |
Bridge loan total cost = monthly interest payments + origination fee + exit costs (often a 'partial' fee for early payoff in some products). For a 12-month bridge at 10% APR + 2% origination on $400K: $40K interest + $8K origination = $48K total cost (12% effective). For shorter actual bridge periods (6 months), effective rate is much higher when origination fee is amortized over actual period.
Frequently Asked Questions
What is a bridge loan?
A short-term loan that lets a buyer close on a new home before the old one sells, using equity in the existing property as collateral. Terms typically run six months to two years.
Why are bridge loan rates higher?
They are short, fast, and carry timing risk for the lender. Bridge loan APRs commonly price 2 to 4 points above prime, plus origination fees of 1% to 3%.
Is a bridge loan interest-only?
Often yes. Many bridge loans pay interest monthly with a balloon for the full principal when the old home sells. Use a calculator matched to the structure your lender offers.
Are there alternatives?
Yes — HELOCs, sale contingencies in the purchase offer, and 'buy before you sell' programs from specialty fintechs. Each has different cost and risk trade-offs.
What if the old home does not sell in time?
Bridge loans often allow extensions for a fee, or convert to longer-term financing. The worst case is selling under pressure — which is why bridge loans suit confident sellers, not desperate ones.
When is this calculator unreliable?
When ignoring origination fees and exit costs (these can add 2-5% to effective bridge cost over typical 6-12 month period), when the bridge requires interest reserve (lender may require setting aside funds for several months of interest at closing — affecting net proceeds), or when permanent financing fails to materialize (catastrophic outcome requiring expensive extensions or distressed sale).

Methodology & Review
Bridge loan payment calculates short-term loan payments — typically interest-only during bridge period (6-12 months). The calculator returns monthly interest cost. U.S. bridge loans 2024: short-term financing 6-24 months; rates 8-15% APR (higher than permanent financing); often used for real estate (gap between selling existing home and buying new) or business situations (acquisition pending permanent financing). High rate reflects short-term nature and elevated risk. RELIABILITY: Reliable for documented bridge loan terms. Less reliable as complete cost picture because bridge loans typically have substantial fees (1-3% origination), prepayment flexibility but often minimum interest period requirements, and assume permanent financing replaces bridge — failure to obtain permanent financing creates major problems.
