Bridging loan calculator, with the real cost

Most calculators show you interest. This one shows the gross loan, the fees rolled into it and what you actually repay at the end — for all three ways of paying interest, side by side.

What’s the bridge for?

Purchase price or market value

You can type shorthand — 750k or 1.2m both work.

60% of value

This is the cash released to you. Fees are added on top to work out the gross loan.

Most bridges run 6–18 months
12 months

How is the interest paid?

No monthly payments. Interest builds up on the balance and is repaid when you sell or refinance.

How bridging interest actually works

Bridging loans are short-term, secured on property and priced as a monthly rate. The difference between these three options is when you pay that interest — and it changes the total by thousands.

Rolled up

Interest is added to the balance each month and compounds. Nothing to pay until you sell or refinance, but the final figure is the highest of the three.

  • No monthly payments
  • No affordability test on payments
  • Best for refurbishments with no rental income

Retained

The lender holds back the whole term’s interest from the loan at the start. You borrow more to cover it, so the gross loan and the LTV are higher.

  • No monthly payments
  • Repaying early may return unused interest
  • Not possible on long terms at high LTV

Monthly (serviced)

You pay the interest each month and repay the loan itself at the end. The cheapest of the three overall, because nothing compounds.

  • Lowest total cost
  • Lender will check you can afford it
  • Suits landlords with rental income
Questions

Bridging finance, answered

What's the difference between a net and a gross bridging loan?

The net loan is the cash released to you. The gross loan is that amount plus the arrangement fee, the broker fee and, on a retained deal, the interest held back for the term. Lenders set their maximum loan to value against the gross figure, which is why borrowing "75% of the value" usually releases noticeably less than 75% in cash.

Why does the rate change when I move the sliders?

Bridging is priced in loan-to-value tiers. As the gross loan rises past each threshold, the monthly rate steps up. Because fees and rolled-up interest are part of the gross loan, a small increase in the cash you need can push the whole deal into a higher tier — the calculator works that loop through for you.

Are these figures an offer?

No. They are an illustration using typical market assumptions so you can sanity-check a deal. Real terms depend on the property, your experience, your credit profile and the exit. A specialist confirms the numbers against live lender criteria before anything is committed.

What counts as an exit strategy?

Usually a sale of the property, or a refinance onto a term mortgage such as a buy-to-let or commercial loan. Lenders underwrite the exit as carefully as the property itself, so evidence matters: an agent's appraisal for a sale, or a decision in principle for a refinance.

How quickly can a bridging loan complete?

It depends on the lender, the valuation and the solicitors on both sides. The single biggest factor is how well the case is packaged at the start — a file with the documents already assembled moves considerably faster than one put together as it goes, which is the part we control.
