Key takeaways
- The gross loan is the headline figure a bridge is set at — the total you contract to repay. The net loan (or net advance) is what actually reaches your account after deductions.
- The gap between the two is created by costs taken off the gross loan up front — typically the arrangement fee and, depending on structure, an interest allowance (retained interest).
- The net figure is the number your plan has to survive on. Budgeting off the gross is the most common and most avoidable bridging mistake.
- How interest is handled — retained, rolled-up or serviced — is the biggest single driver of how far the net sits below the gross.

What this article does
Ask “how much can I borrow on a bridge?” and you will get a gross figure. Ask “how much will actually reach me?” and you get a different, smaller number — and that second number is the one that decides whether your deal works. This is information, not advice: it explains the difference between the gross and net loan, what causes the gap, how the interest structure and valuation feed into it, and how to work out your real net before you commit. For the full cost breakdown, see our guide on how much bridging finance costs.
What is the gross loan?
The gross loan is the total facility the bridge is written for — the figure quoted first and the amount you are contracting to repay at the end (plus any interest that has not been paid along the way). It is the number that sizes the deal and the one measured against the property’s value as loan-to-value. But it is not the cash that lands in your account, because the lender typically takes certain costs out of it before releasing the rest.
What is the net loan (net advance)?
The net loan — often called the net advance — is what actually reaches you after those deductions come off the gross. Commonly that means the arrangement fee and, where interest is retained, an allowance for the interest over the expected term. What is left is the money you can actually use to complete the purchase, fund the works, or clear the bill you took the bridge for.
This is the figure your plan has to live on. If you need a specific sum to complete, it is the net that has to hit it — not the gross. Working backwards from the net you actually need is the sensible way to size a bridge.
Payam’s experience — The single thing people get wrong most is assuming the headline figure is what they get. Bridging is quoted on a gross basis, and once you net off the interest and fees for the term, the usable amount drops noticeably below that headline — sometimes by more than people expect, and more still where a second charge or adverse credit is involved. I always work it the other way round: start from the net a client actually needs to complete the deal, and build the gross up from there, so nobody discovers a shortfall on completion day. If the usable figure does not reach what the deal needs, that is a conversation to have at the start, not at the end.
What creates the gap between gross and net?
Several deductions can sit between the gross loan and the net advance. The main ones:
- Interest, where it is retained — if interest for the term is held back up front (rather than paid monthly or rolled up), that allowance comes straight off the gross. This is usually the largest single deduction.
- The arrangement fee — the lender’s set-up fee, often added to (and so deducted from) the loan.
- Valuation and legal costs — depending on the deal, some costs are settled from the advance; others you pay separately.
Because retained interest is often the biggest deduction, the interest structure you choose is the biggest lever on the gross-to-net gap. Retained interest pulls the net down the most; rolled-up leaves more on day one but grows the end balance; serviced leaves the most available on day one but requires monthly payments. Our guide on retained vs rolled-up vs serviced interest goes into that mechanism in depth.
Where the valuation comes in
The gross loan itself is capped by the property’s value and the lender’s loan-to-value limit — and on a bridge the value a lender uses is not always the open market figure. Many lenders size lending against a more cautious resale basis, so a conservative valuation can hold the gross down before any deductions even start. In other words, two things can shrink what you end up with: a cautious valuation caps the gross, and the deductions then reduce the gross to the net. Planning around both is what keeps a deal from unravelling late.
How to work out your real net
- Start from the net you actually need — the sum required to complete, fund the works, or settle the liability.
- Decide the interest structure — retained, rolled-up or serviced — because it drives the biggest deduction.
- Add the known costs — arrangement fee and any legal/valuation costs settled from the loan.
- Check it against value and LTV — make sure the gross needed to deliver your net still sits within what the property and the lender’s basis will support.
- Model it before you commit — see how the net moves with term and structure on our bridging loan calculator.

Gross vs net bridging — frequently asked questions
What is the difference between a gross and net bridging loan?
The gross loan is the headline figure you contract to repay; the net loan (net advance) is what actually reaches you after deductions such as the arrangement fee and any retained interest. The net is the money you can actually use.
Why is the net advance lower than the loan I was quoted?
Because lenders commonly deduct certain costs from the gross loan before releasing it — most often an interest allowance (where interest is retained) and the arrangement fee. Those deductions turn the gross figure into a smaller net advance.
Can I avoid the gross-to-net gap?
You can reduce how much is deducted up front — for example, servicing the interest monthly rather than retaining it leaves more of the loan available on day one — but it requires income to cover the payments. There is always some cost; the aim is to structure it so your net still meets what the deal needs.
Should I size a bridge by the gross or the net?
By the net. Start from the sum you actually need to reach and build the gross up from there, so there is no shortfall on completion. Sizing by the gross is the most common way people end up short.
Does the valuation affect the net I receive?
Indirectly, yes. The valuation and the lender’s loan-to-value limit cap the gross loan, and on a bridge the lender may use a cautious resale value rather than open market value. A lower cap on the gross means a lower net once deductions come off.
Is the gross or net figure used for loan-to-value?
Loan-to-value is generally measured against the gross facility relative to the property’s value, since the gross is what is secured and repayable. The net advance is what reaches you after deductions — a separate figure that matters for your cash flow rather than the LTV calculation.
Apart from a down-valuation will the net change from my original quote?
Yes, there are a variety of reasons the net loan might change during the course of the process. Often the legal costs are undeterminable at outset; underwriting; the property might need to be re-inspected more frequently than originally thought at outset – are some of the more common ones. Bridging finance approval can be quite fluid and you should never 100% rely on expected funds until they land in your pocket.
Closing
Gross is what you repay; net is what you receive. The gap between them — driven mostly by how the interest is handled — is where deals quietly come up short, so the discipline is simple: size the bridge from the net you actually need, not the gross you are quoted.

Bridging loans are short-term finance and are typically more expensive than standard mortgages. You must have a clear and credible exit strategy — usually the sale of the property or a refinance onto longer-term lending — to be considered for a bridging loan. Interest is normally charged monthly and can be rolled or retained from the loan; this means the amount you repay may be higher than the amount originally borrowed.
