TL;DR: Interest on bridging loans is typically calculated monthly and “rolled up” into the loan balance rather than being paid every month. While this helps with cash flow, it means the total debt grows over time, and your property may be at risk if repayments are not made.

How is interest charged on a bridging loan?

Bridging loans are a specialist type of short-term finance designed to “bridge” a gap in funding. They are commonly used by property investors, homebuyers, and businesses to secure a property quickly or fund a renovation before long-term finance becomes available. However, because these loans are short-term and often involve higher risks for the lender, the way interest is charged differs significantly from a traditional mortgage.

When you take out a standard mortgage, you usually pay a monthly amount that includes both interest and a portion of the capital. With a bridging loan, the structure is designed to be more flexible, often requiring no monthly payments at all until the end of the term. Understanding the nuances of how lenders calculate and apply these charges is essential for anyone considering this type of borrowing.

Monthly interest rates vs APR

The first thing to note about how interest is charged on a bridging loan is the time frame. While most loans and mortgages use an Annual Percentage Rate (APR) to show the yearly cost, bridging lenders primarily quote interest as a monthly rate. This is because bridging loans are usually intended to last between 1 and 12 months, though some can extend to 24 months.

A typical monthly interest rate might range from 0.5% to 1.5%. While 1% might sound low, it is important to remember that this is a monthly figure. If you were to look at this as an annual rate, it would be roughly 12% plus any compounded interest and fees. This reflects the short-term, high-speed nature of the finance. Because the lender is often moving very quickly and perhaps lending on a property that is not currently in a “mortgageable” state, the costs are higher than standard long-term borrowing.

The three main ways interest is applied

Lenders generally offer three ways to handle interest charges. The method chosen will depend on your financial circumstances, the lender’s criteria, and your “exit strategy” (how you plan to pay the loan back).

1. Rolled-up interest

This is the most common method for bridging loans. With rolled-up interest, you do not make any monthly payments to the lender. Instead, the interest is calculated monthly and added to the total loan amount. You pay back the original sum borrowed plus all the accumulated interest in one lump sum at the end of the loan term.

The benefit of this method is that it helps your cash flow, as you don’t need to find money for monthly instalments. The downside is that interest may compound, meaning you are eventually paying interest on the interest already added to the balance.

2. Retained interest

Retained interest is similar to rolled-up interest in that you do not make monthly payments. However, instead of adding interest to the balance as you go, the lender “retains” the total interest cost from the initial loan advance. For example, if you borrow £100,000 and the total interest for 12 months is estimated at £12,000, the lender might only give you £88,000 at the start. You still owe £100,000 at the end.

This method ensures the lender has the interest “in the bank” from day one. If you pay the loan back early, many lenders will rebate the “un-used” interest, provided there is no minimum term clause in the contract.

3. Serviced interest

Serviced interest works more like a traditional mortgage. You pay the interest monthly as it falls due. This keeps the loan balance from growing, meaning you only owe the original capital amount at the end of the term. Lenders usually only offer this if you can prove you have a reliable monthly income to cover the payments. This is less common in bridging because many borrowers are using their cash for property renovations or are waiting for a property sale to complete.

Open vs closed bridging loans

How interest is charged can also be influenced by whether the loan is “open” or “closed.” This refers to your exit strategy.

• Closed bridging loans: These have a fixed repayment date. You might use this if you have already exchanged contracts on a property sale and know exactly when the funds will arrive. Because there is more certainty, interest rates can sometimes be slightly lower.
• Open bridging loans: These do not have a firm end date, though they will usually have a maximum term (e.g., 12 months). These are more flexible but often come with slightly higher interest rates because the lender has less certainty about when they will get their money back.

Regardless of the type, you should always have a clear plan for repayment. MoneyHelper provides impartial guidance on the risks associated with bridging finance and the importance of a solid exit strategy.

The impact of compounding

Most bridging lenders use compound interest rather than simple interest. Simple interest is calculated only on the original amount borrowed. Compound interest is calculated on the principal plus the interest that has already been added. In a rolled-up interest scenario, this means the amount you owe grows more quickly as the months pass. It is vital to ask your lender for a “redemption statement” or an illustration that shows the total cost of borrowing if the loan runs for its full term.

Other costs that affect the total price

When asking how interest is charged, it is also important to look at the other fees that make up the “total cost of credit.” These charges are often added to the loan and can attract interest themselves if they are rolled up.

• Arrangement fees: Typically 1% to 2% of the loan amount, charged by the lender for setting up the facility.
• Valuation fees: The cost of having a professional surveyor value the property.
• Legal fees: You will usually have to pay for both your own solicitor and the lender’s solicitor.
• Exit fees: Some lenders charge a fee (often 1%) when you pay the loan off, though many modern bridging loans do not have exit fees.
• Broker fees: If you use a broker to find the deal, they may charge a fee for their services.

Because these loans involve a deep look at your financial health and the value of your assets, lenders will perform various checks. Get your free credit search here. It’s free for 30 days and costs £14.99 per month thereafter if you don’t cancel it. You can cancel at anytime. (Ad)

Risks and consequences of bridging finance

While bridging loans are a powerful tool for property professionals, they carry significant risks. The most important thing to remember is that your property may be at risk if repayments are not made. Unlike some forms of unsecured borrowing, bridging loans are secured against your assets.

If you fail to repay the loan by the end of the term, or if you miss payments on a serviced loan, the consequences can be severe. Lenders may initiate legal action, which can lead to the repossession of the property. Additionally, most contracts include “default” clauses. If you default, the lender may increase the interest rate significantly—sometimes doubling it—and apply additional charges for late payment or breach of contract. This can cause the debt to spiral very quickly.

People also asked

Can you pay off a bridging loan early?

Yes, most bridging loans allow for early repayment. Many lenders do not charge exit fees, though some may have a “minimum term,” such as one or three months, where you must pay the interest for that period even if you settle the loan sooner.

Do I need a deposit for a bridging loan?

Lenders typically lend up to 70% or 75% of the property’s value (Loan to Value or LTV). This means you generally need a “deposit” or equity in the property of at least 25% to 30%, though you can sometimes use other properties as additional security.

Is bridging loan interest tax-deductible?

If the bridging loan is used for business purposes or a buy-to-let investment, the interest may be a tax-deductible expense. However, tax laws are complex and change frequently, so you should always consult a qualified accountant for advice.

How long does it take to get a bridging loan?

One of the main benefits of bridging finance is speed. While a standard mortgage can take months, a bridging loan can often be arranged in 5 to 14 days, depending on the complexity of the case and the speed of the valuation.

What is the average interest rate on a bridging loan?

As of recent market trends, average rates typically sit between 0.7% and 1.2% per month. The exact rate you are offered will depend on your credit history, the type of property, and the amount of equity you have.

Final considerations on interest

In summary, interest on a bridging loan is usually charged as a monthly rate and is often “rolled up” into the final payment. This structure provides flexibility for those who do not have immediate cash flow but expect a significant payout in the near future. However, the costs are higher than traditional borrowing, and the risks are substantial.

Before proceeding, ensure you have a “bulletproof” exit strategy. Whether it is the sale of a property, a refinance onto a standard mortgage, or an inheritance, you must be certain of how the capital and accumulated interest will be paid back. Always read the fine print regarding compound interest and default charges to ensure you understand exactly how much the loan will cost if things don’t go exactly to plan.
