Bridge Loan Spread Calculator
Bridge loans are typically SOFR + spread with a rate floor. This calculator computes the current all-in rate, stress-tests debt service against an index shock, and shows the increase — the number every bridge borrower should run before closing.
Current all-in rate

Rate after stress shock

Current annual debt service

Debt service increase at shock

How the math works
Bridge loans are almost always floating over SOFR (or prime) plus a spread. Spread + index together = all-in rate, subject to a floor. Stress testing against a 100-200 bps index move is standard pre-close sanity check; if the stressed rate breaks DSCR, buy a rate cap.
Rate cap cost scales with strike and term. Lower cap = more expensive. Always budget cap purchase as part of closing costs on floating-rate deals.

How this calculator works
What this page estimates
This Bridge Loan Spread Calculator is built to give a quick, browser-based estimate for bridge loan spread. Bridge loans are typically SOFR + spread with a rate floor. This calculator computes the current all-in rate, stress-tests debt service against an index shock, and shows the increase — the number every bridge borrower should run before closing. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the bridge loan spread result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this bridge loan spread estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.
How to Use
- Enter the benchmark index (SOFR or prime).
- Enter the lender spread in bps (typical 250-400 on bank bridge).
- Enter loan amount and rate floor.
- Enter amortization months (0 for interest-only, most common on bridge).
- Enter the stress shock and read current vs stressed debt service.
Frequently Asked Questions
Why floor?
Lenders want minimum yield even if rates crash. Floor rate protects lender economics and is standard on all SOFR-based loans. Floor is usually the rate at closing.
How to hedge?
Buy a rate cap at an index strike that keeps debt service coverage within comfort. Cap cost scales with strike — a 5% SOFR cap is much cheaper than a 3% cap.
Interest-only vs amortizing?
Most bridge is IO for 2-3 years. Amortizing bridge is rare — it crushes cash flow. Check the loan docs.
