Interpreting the results
Brickflow’s bridging finance calculator is an incredibly useful tool, and should be the first port of call for every property professional before committing to a purchase.
Most bridging loan calculators only estimate repayments, whereas Brickflow compares live lending options based on your project.
To use the bridging calculator to your full advantage, the below will help you to better interpret and understand what is shown in the results:
- Maximum Loan to Value (LTV) ratios for your project: Lenders all have different caps on what they’ll lend against the land/property cost and build costs (if applicable).
- Gross loan vs net loan: Gross loan is the total amount being borrowed and includes all interest charges and fees. Net loan is the amount made available to the borrower after deduction interest and fees, i.e. the amount you’ll receive on loan drawdown.
- Monthly and annual interest charges: Interest can be serviced (paid monthly) or rolled up, and some lenders charge interest monthly rather than daily. This means you pay an entire month’s interest even if exiting part-way through the month, so always ascertain how its charged from the outset.
- Arrangement and exit fees: Exit fees are pretty uncommon, with almost none of the Brickflow lenders charging exit fees. Typical arrangement fees are up to 2% of the gross loan.
- True monthly costs (TMC): Brickflow uses a calculation of (Interest Rate / 12) + (arrangement fee + exit fee) / number of months = TMC to help you better understand the cost of your loan.
- Deposit requirements: Materially affected by the LTV ratios and net loan. A higher leverage loan, for example with 80% LTV, will require less deposit input than a loan with only 60% LTV.
Your final redemption payment (to pay off the loan) will include the original amount of capital borrowed plus the accrued interest.
The below example shows these numbers in practice.
Bridging loan example
Let’s use a property purchase with refurbishment bridging finance over 12 months:
- Purchase price: £200,000
- Purchase costs: £10,000 (usually 5% of the purchase price)
- Costs of works: £50,000
- Gross development value (GDV): £340,000

The lender offering the largest loan with the lowest true monthly costs has an interest rate of 10.08% annually and a 2% arrangement fee, equalling an estimated total lender cost of £23,491.
Additional bridging loan costs to be aware of that are not shown in the calculator:
- Legal fees: you’ll have to pay your own legal fees as well as the lenders
- Broker fees: typically paid by the lender
- Valuation or survey fees
Comparing bridging lender types
Bridging loan pricing varies by lender type, loan-to-value, borrower profile, property type and exit strategy. As a high-level guide, the table below shows how different parts of the UK bridging market typically compare.
|
Lender type |
Typical monthly rates |
Max LTV |
Minimum loan size |
DIP speed |
First-time investors |
|
High-street banks |
Usually lower, often base rate + a lower margin, e.g 0.10%–0.40% per month |
Typically 60–70% |
Usually higher and case-dependent |
Minutes, with Brickflow |
Limited appetite unless low risk deal or relationship-led |
|
Specialist bridging lenders |
Mid-market, often base rate + a moderate margin, e.g. 0.40%–0.90% per month |
Typically 70–80% |
Often from around £100k |
Minutes, with Brickflow |
Commonly accepted, subject to deal strength and exit |
|
Private / alternative lenders |
Higher, often base rate + a higher margin, e.g. 0.80%–1.40%+ per month |
Typically 70–90%+, with higher leverage possible in specific cases |
Case-dependent |
Minutes, with Brickflow |
Often accepted, including more complex profiles |
Rates are indicative only, and the Bank of England rate environment remains an important backdrop, but individual bridging rates are always subject to lender appetite, underwriting, loan size, property type, LTV and exit strategy. The live Brickflow bridging loan calculator gives personalised results based on your actual deal.
Matching lender types to projects
There’s really no one ‘best lender’, but rather the best bridging lender depends on the deal and the borrower.
Bridging lenders compete differently, and the cheapest lender is not always the best fit. Some compete on rate, others on speed, leverage, property type or borrower flexibility.
Here’s a broad guide on matching lender types to projects, and best lenders:
-
For speed: Specialist bridging lenders and private / alternative lenders, especially for auctions, chain breaks and time-sensitive purchases requiring fast bridging loans.
-
For first-time investors: Specialist bridging lenders, where the deal is strong, the exit is credible and the borrower has suitable professional support.
-
For leverage: Specialist and private / alternative lenders, particularly where the borrower needs a higher LTV or larger net loan.
-
For adverse credit: Private / alternative lenders, as they are more likely to assess the wider deal rather than relying only on rigid credit criteria.
-
For lowest rates: High-street banks or lower-risk specialist lenders, usually for straightforward assets, lower LTVs and clear exits.
In practice, the right lender is rarely just the cheapest one. It is the lender most likely to fund the deal at the right speed, leverage and level of flexibility.
Bridging loan criteria & Eligibility
As with all specialist finance, every lender will have different eligibility criteria, but the bridging market has grown substantially in recent years and covers a vast array of borrowing requirements.
Brickflow's bridging loan calculator lets you filter your search results by different criteria; for example, first-time investor, based overseas, serviced interest, property type, etc. However, there are some minimal input requirements to use the calculator such as property details, required loan term, refurb costs, and any applicant has to meet basic requirements:
-
Aged 18 or over (some lenders may have an upper age limit)
-
UK resident or UK national living abroad
-
Employed, self-employed or retired
-
An individual, Limited Company, LLP or partnership
-
Short-term loan only, typically up to 24 months
- Have a valid exit strategy (essential for securing the loan)
Then it comes down to the property, experience, credit history and more. As a rule of thumb, first-time developers will typically have fewer lender options, and can incur lower leverage and higher rates. Likewise for overseas borrowers, who are accepted by many lenders, but may face differing loan terms. Property conditions also affect lender appetite, for example many lenders avoid heavy refurbishment projects due to the additional risk.

How does a bridging loan calculator work?
A bridging loan calculator works by using the property, loan and borrower details you enter to search the market and estimate how a bridging loan could be structured.
Brickflow’s bridging loan calculator goes a step further by comparing your inputs against live lender criteria and pricing data, returning accurate borrowing options that show loan size, interest, fees, profit outcome and more. The results help you assess whether a deal is viable before progressing to a formal application.
What inputs do I need to calculate bridging loan costs?
To calculate bridging loan costs, you’ll need to provide key details about the transaction, such as the property type, purchase price, expected works (if applicable), loan term and your intended exit strategy. These inputs allow the calculator to assess loan-to-value limits, interest structure and fees that apply to your scenario.
Does the calculator include interest and fees?
Yes. Brickflow’s bridging loan calculator includes interest charges and typical lender fees, such as arrangement fees, and shows estimated total lender costs. Some costs associated with completing a loan (such as legal fees, valuation fees and broker fees) are not shown in the calculator and should be factored in separately.
What fees are involved with a bridging loan?
Common bridging loan fees include arrangement fees, valuation fees, legal fees, broker fees and exit fees, depending on the lender. Interest can usually be paid monthly, retained or rolled up into the loan.
How much can I borrow?
How much you can borrow depends on various factors, but it’s a vast scale ranging from £25,000 - £350 million. Typically, lenders will offer up to 75% LTV on a gross loan basis and 100% of build costs.
To determine their lending limits, they will consider:
- The property or site, it’s location & condition, your plans for the property
- You as a borrower, including credit file, experience in property investment, employment status
- Your exit strategy
- The value of your assets used to secure the loan
How much do you need to put down for a bridging loan?
This depends on the value of the property or site you want to fund with the bridging loan and the lender's lending limits.
For example, on a £200,000 purchase with £10,000 purchase costs + £52,500 total build costs, if the lender funds 100% of the build costs (£52,500) and 75% of the purchase costs (£150,000), you will need a deposit of £60,000.
What is the typical interest on a bridging loan?
Currently, bridging loan rates are around 8% - 12% annually.
Do you pay a bridging loan monthly?
Bridging loans are typically repaid in one lump sum at the end of the term. The final payment includes the initial capital borrowed plus interest charges.
Can I get a bridging loan with no money?
Bridging loans are secured against your property, so monthly income is not essential to securing a bridging loan. However you will still need an amount of money for the deposit – how much depends on the value of the property you intend to fund.
In some circumstances, you can get a 100% bridging loan, but you would need additional assets as security. Rather than 100% finance, it is more of a ‘cashless deal’. It can be difficult to meet the criteria, but some lenders in specific arrangements can offer this type of funding.
How is bridging loan interest calculated?
Interest is calculated on a monthly gross loan basis, so whatever the interest charges are, they are applied to the purchase loan, build loan, interest, and arrangement fee.
You will only pay interest for the duration of your loan, even if you exit the loan earlier than the originally agreed term.
Are the results an exact quote or an estimate?
The results shown by a bridging loan calculator are indicative, not a binding offer. Final pricing and terms are always subject to valuation, legal due diligence and lender credit approval.
However, Brickflow examines over 200,000 lender data points weekly, delivering actual real-time loan options. You can progress from indicative results to a Decision in Principle to lock in the rates shown - our fastest DIP took just 4 minutes.

When should I use a bridging loan vs a mortgage?
A bridging loan is the right tool when speed or flexibility is critical, such as buying at auction, funding a property that isn't mortgageable in its current condition, or financing land. A mortgage is more appropriate when you're purchasing a property in good condition that you plan to hold long-term.
Can first-time investors get bridging finance?
Yes, some bridging lenders will consider first-time investors. The deal needs to be strong, with a clear exit strategy, suitable security and enough evidence that the borrower can deliver the project.
What’s the difference between regulated and unregulated bridging loans?
A regulated bridging loan is usually secured against a property you live in or plan to live in. An unregulated bridging loan is typically used for investment or business purposes, such as buying, refinancing or refurbishing a property.
What happens if you cannot repay a bridging loan on time?
If you cannot repay on time, speak to your lender as early as possible. They may consider an extension, but extra interest and fees can apply. If no repayment plan is agreed, the lender could take enforcement action against the secured property.
