No. Bridge loans are often interest-only with payoff at maturity. This models IO with no principal reduction.

Does it include fees?

Only points are included. Add underwriting/appraisal/extension fees separately if needed.

What if the term extends?

Add more months of interest to estimate the new total cost and check your loan documents for any extension fees or penalty rate changes. Even a short extension can meaningfully increase total interest on high-rate bridge or hard-money loans.

Assumes fixed APR. Recalculate if your rate changes.

Can I model paydown during the term?

This version assumes no principal paydown. For paydown, subtract planned principal reductions from the balance and rerun.

Is a bridge loan better than making a contingent offer?

It depends on your market and risk tolerance. This calculator helps you quantify the financing cost of a bridge; you still need to weigh that against the competitive advantage of a non-contingent offer and the risk of carrying two properties at once if your existing home takes longer to sell.

Can I use this for investment or hard-money loans?

Yes, as a simplified cost model. Many hard-money and short-term rehab loans look similar to bridge loans—interest-only, short term, and points upfront. As long as the structure is interest-only with a single payoff at exit, you can plug the numbers in here to get a directional sense of total cost.

Overview

Bridge loans are short-term financing designed to “bridge” a gap between today and a future event such as selling your current home, closing on a new purchase, or refinancing into long-term debt. Because they are temporary and often carry higher rates and points than traditional mortgages, it’s important to understand the true cost of using one before you sign.

This bridge loan calculator helps you do exactly that by breaking the math into clear pieces: monthly interest-only payments, the cost of lender points, total interest over the term, and the final payoff amount at exit. You enter the bridge amount, APR, term in months, and points percentage, and the tool shows you how much you’ll pay to carry the loan until your sale, refinance, or other payoff event.

How to use this calculator

Enter the bridge loan amount you expect to borrow.
Enter the quoted APR, term in months, and lender points percentage from your loan offer.
Review the estimated interest-only monthly payment to understand monthly cash flow impact.
Check total interest and points cost to see the full dollar cost of the bridge over your expected term.
Look at the total payoff amount and compare it against your expected sale proceeds or refinance terms to confirm the bridge still fits your plan.
Adjust APR, term, or points to compare multiple lender offers or alternative strategies (like using a HELOC or delaying the purchase).

Inputs explained

Bridge loan amount: Short-term loan size you’ll carry until exit (sale, refi, or permanent financing).
APR (%): Annual percentage rate for the bridge loan, including interest but not separate fees or points.
Term (months): Expected bridge duration in months until payoff or refinance; include some buffer for delays.
Points (%): Upfront lender points as a percent of the loan amount (for example, 1.5–3%). Points are paid at closing and increase your all-in cost even though they don’t change the monthly interest payment.

How it works

You start by entering the bridge loan amount, which is the short-term balance you expect to carry until your exit (sale, refi, or other payoff).

We convert the annual percentage rate (APR) into a monthly rate by dividing by 12, then multiply that monthly rate by the loan amount to estimate an interest-only monthly payment.

Points are modeled as a one-time upfront charge equal to the bridge amount multiplied by the points percentage. For example, 2 points on a $150,000 loan is $3,000.

Total interest over the term is calculated as monthly interest × number of months, assuming the balance stays roughly constant and payments are interest-only.

Total payoff combines the original principal, the one-time points charge, and all interest paid over the term so you can see the complete carrying cost of using the bridge.

Because the model assumes a fixed rate and no principal reduction, it’s intentionally simple and transparent—ideal for quick what-if comparisons rather than detailed amortization.

Formula

Monthly rate = APR ÷ 12
Monthly interest = Amount × Monthly rate
Points cost = Amount × Points%
Total interest = Monthly interest × Term
Total payoff = Amount + Points cost + Total interest

When to use it

Evaluating cost to carry a bridge while waiting for a sale or permanent financing.
Comparing bridge vs HELOC vs short-term hard money costs.
Estimating payoff amount at the end of the bridge term.
Stress-testing a delayed sale scenario by increasing the term in months to see how much extra interest an extended listing or construction delay might add.
Helping a real estate investor understand the carrying cost of a rehab project where a bridge or hard-money loan will be paid off with a sale or refinance.
Giving buyers and their agents a quick read on whether using a bridge to make a non-contingent offer is financially reasonable compared with waiting to sell first.

Tips & cautions

Bridge loans are often interest-only; plan for a payoff/refi at term end rather than expecting the balance to amortize away.
Include lender fees beyond points separately if applicable—application, underwriting, appraisal, legal, or extension fees can materially change total cost.
If the term might extend, budget for more months of interest or potential extension fees; model a conservative “what if this takes 3–6 months longer?” scenario.
Ask lenders whether points are charged on the full commitment amount or only on the amount you actually draw—this can change the effective cost materially.
Compare offers not just on rate, but on total dollars paid: a slightly higher rate with lower points may be cheaper than a low-rate, high-point structure over a short term.
Use a slightly longer term and a slightly higher APR than quoted when modeling worst-case scenarios, especially in slower markets or complex transactions.
Assumes interest-only payments with no principal reduction; if you plan to pay down principal during the term, your real interest cost will be somewhat lower.
Does not include extension fees, appraisal, legal, or underwriting fees; these should be added manually when estimating all-in costs.
Fixed APR assumed; some bridge loans can have variable rates or step-ups that change your monthly interest over time.
Does not model interest reserves, construction draws, or rehab budgets that are sometimes built into more complex bridge or hard-money structures.
Ignores tax treatment of interest—work with a tax professional if you plan to deduct interest as an investment or business expense.

$200k bridge, 10% APR, 9 months, 1.5 points

Total payoff ≈ $218,000

Deep dive

This bridge loan calculator shows monthly interest, points cost, and total payoff so you can see the true carrying cost of short-term financing before you sell or refinance. Instead of guessing from a headline rate, you can see exactly how dollars of interest and points add up over the months you expect to carry the loan.

Many borrowers only see the convenience of closing quickly or buying before they sell, but the trade-off is higher rates and upfront costs. By breaking your bridge into monthly interest, total interest, and one-time points, this calculator makes it easy to compare bridge offers, HELOCs, and other short-term options on an apples-to-apples cost basis.

You can also use the tool as a negotiation and planning aid. Run one scenario at the quoted rate and points, then another with slightly better terms to see how much room you have to negotiate. Test a longer term to see how delays would affect your payoff amount, or plug in different exit timelines for a flip or rehab project to make sure your deal still pencils out after financing costs.
