Cost breakdown
What affects your bridging cost
Peak debt - This is the total amount you owe during the bridge: your existing mortgage plus the full purchase price of your new property. It is the single biggest driver of cost.

Interest rate - Bridging rates vary between lenders. Some charge a premium over standard variable rates, others offer competitive bridging-specific products. The difference can be thousands over the bridge.

Time on bridge - Every month you hold both properties adds another month of interest on the full peak debt. A fast sale saves real money. Lendology helps you set a realistic timeline based on your suburb and market conditions.

Understanding bridging loan costs

A bridging loan lets you purchase a new property before selling your existing one. During the bridging period, you effectively hold two properties and owe on both - your existing mortgage continues while a new loan covers the purchase. The combined total is called your peak debt, and it is the main driver of your bridging cost.

The cost of a bridging loan comes down to three things: the size of your peak debt, the interest rate, and how long the bridge lasts. Most lenders capitalise the interest during the bridging period, meaning you do not make repayments - the interest accrues and is settled when your existing property sells. This simplifies your cash flow but means the total cost grows with every month on bridge.

Modelling the numbers before you commit is essential. A six-month bridge at 7.5% on a $1.5M peak debt costs around $56,000 in interest alone. If the bridge extends to nine months, that climbs to $84,000. Lendology runs these scenarios with you before you make an offer, so you know exactly what you are signing up for and can plan accordingly.

How to use this calculator

Enter your current property value, existing mortgage balance, the price of the home you want to buy, how long you expect the bridge to last, and the interest rate. The calculator shows your peak debt, the monthly and total interest cost, and your estimated equity position after the sale. Actual costs depend on the lender, loan structure and any fees - this gives you a solid starting point for planning.

Frequently asked questions

How much does a bridging loan cost?

Bridging loan costs depend on the interest rate and how long you hold both properties. On a peak debt of $1.5M at 7.5%, monthly interest is around $9,375. Over a 6-month bridge, total interest cost is approximately $56,000. Lendology models the exact cost for your situation before you commit.

How long can I have a bridging loan?

Most lenders allow bridging periods of 6 to 12 months, though some extend to 24 months in special circumstances. The shorter the bridge, the lower the cost. Lendology helps you plan realistic timelines based on your local market.

Do I make repayments during the bridging period?

Most bridging loans capitalise interest during the bridging period, meaning you do not make separate repayments. The interest accrues and is paid when your existing property sells. Some lenders offer the option to make interest-only payments during the bridge to reduce the total cost.

What happens if my property does not sell in time?

If your property has not sold by the end of the bridging period, some lenders allow extensions. Others may require you to list with a new agent or reduce the price. Lendology selects lenders with flexible bridging policies and realistic timeframes to minimise this risk.
