A borrowing capacity calculator is a tool used to estimate the amount of money you can afford to borrow based on your financial situation, including income, expenses and credit history. The calculator takes these factors into account to provide an estimated borrowing limit, which can help you make informed decisions about taking out loans or mortgages.

It's important to note that these calculations are only estimates and the actual borrowing capacity may vary based on lender requirements and other factors. Additionally, it's always recommended to consult with a financial adviser before making a borrowing decision, as they can provide personalised advice on borrowing capacity and financial planning.
