Bridging loans are short-term, typically 1-18 months, and priced monthly rather than annually. A 1% monthly rate is around 12.7% APR once compounded. Plus a 2% arrangement fee on day one. A 200,000 bridge at 1% per month for 6 months, 2% fee: roughly 12,000 interest and 4,000 fee — 16,000 total.

Run it with sensible defaults

Using loan amount of 200,000, monthly rate of 1%, term of 6, arrangement fee of 2%, the calculation works out to 16,000.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Loan Amount, Monthly Rate, Term, and Arrangement Fee — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Simple monthly interest (most bridge loans) plus arrangement fee. Assumes interest rolled up and paid at exit; serviced interest would be similar in total. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

What the headline rate hides

Lenders quote a rate; what you pay is a blend of that rate, fees, insurance, and any early-repayment penalty built into the product. The figure here isolates the core interest cost so you can compare like-for-like across deals — then add the other costs separately before signing anything.

What this doesn't capture

The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.

Frequently Asked Questions

Why not an APR figure?
Bridging is short-term and APR figures are designed for multi-year loans. Lenders quote monthly because that matches how the product works.
Rolled-up vs serviced?
Rolled-up accrues interest to repayment date. Serviced pays it monthly. Total costs are close; cashflow differs.
Why so expensive?
Speed and short term. Bridging underwrites in days where mortgages take weeks. That speed premium costs more.
Typical use cases?
Chain breaks, auction purchases, refurb-to-sell deals. Short-term gap funding until permanent finance or sale completes.
