IMPORTANT: Our bridging loan calculator is designed to give a useful indication of typical bridging loan costs only based on the inputs provided, and does not constitute any form of financial advice. In practice, bridging loan pricing is influenced by more than just the headline interest rate and loan amount. Lender appetite, security type, exit strategy, borrower structure and individual fee arrangements can all affect the actual terms available. We cannot accept responsibility for errors as a result of using this calculator. Please speak to one of our brokers if you require assistance or further advice.

Understanding Your Bridging Loan Calculator Results

Your bridging loan results illustrate the total cost and structure of a short-term loan based on the figures you have entered. Each output provides a different perspective on how the loan is likely to work in practice.

The total interest cost shows the full interest charge over the loan term, calculated at the monthly rate entered. For retained interest, this amount is deducted from the gross loan at drawdown, reducing the day-one advance to the borrower. For rolled-up interest, the balance compounds monthly and is repaid in full at exit. For serviced interest, the borrower makes monthly interest payments throughout the term.

The redemption balance is the total amount due at exit, comprising the gross loan plus any rolled-up interest and exit fees. The net day-one advance shows what the borrower actually receives after upfront deductions, while the net after all costs figure illustrates the true economic value of the loan once interest and all fees are accounted for.

This calculator is best used as an indicative planning tool only. While it provides an estimated cost breakdown, lenders will also consider security value, exit strategy, borrower experience and their own pricing at the time of application.

Worked Bridging Loan  Example

To demonstrate how the calculator can be used in practice, consider a typical bridging loan scenario.

A developer is purchasing a property valued at £500,000 and requires a loan of £300,000 for the purchase and a further £50,000 for refurbishment works, giving a gross loan of £350,000. Using a monthly interest rate of 0.75% on a retained basis over a 12-month term, with a 2% arrangement fee and 1% exit fee, the calculator estimates the total interest cost, net day-one advance and redemption balance based on these inputs.

This example illustrates how the choice of interest type, fee structure and loan term can materially affect both the amount received on day one and the total cost of the facility. Even modest differences in monthly rate or term length can have a significant impact on the overall borrowing cost and exit position.

Lender Insight on Bridging Finance

Bridging loan pricing and criteria vary considerably across the lending market. Interest rates, maximum loan-to-value, acceptable security types and fee structures differ between lenders, and the most competitive terms are not always available from the most widely recognised providers. Specialist lenders, challenger banks and private credit funds each operate with different appetites, meaning the right lender for a particular transaction depends heavily on the specifics of the deal.

Bridging Loan Calculator FAQs

A bridging loan is a short-term secured loan typically used to fund a property purchase or refurbishment where speed of completion or flexibility is required, with repayment made from a defined exit strategy such as a sale or refinance.

Retained interest is calculated upfront and deducted from the gross loan at drawdown, so no monthly payments are required. Rolled-up interest compounds on the outstanding balance and is repaid at exit. Serviced interest is paid monthly by the borrower throughout the term, reducing the overall redemption balance.

The calculator estimates the net day-one advance after deducting upfront costs, and shows the net position after all costs including interest and fees. Actual amounts will depend on the specific fee structure and terms agreed with the lender.

Yes. Monthly interest rates, arrangement fees, exit fees and the treatment of valuation and legal costs vary considerably. Even small differences in rate or fee structure can have a meaningful impact on the total cost, particularly over longer terms.

Yes. Lenders require a credible exit strategy, typically a property sale, refinance onto a term mortgage or another defined repayment source. The exit strategy needs to be clear and realistic before a lender will approve a bridging facility.

The calculator includes interest, arrangement fee, exit fee and third-party costs such as legal and valuation fees. It does not account for stamp duty, broker fees or any costs specific to an individual lender's fee structure, which should be confirmed directly with the lender or your broker.
