About this calculator
Equity is your share of the property — what would be left if you sold today and paid off the mortgage.
- Banks usually require 20% retained equity for top-ups or refinancing.
- Use this to see if you qualify for a renovation loan or to drop low-equity premiums.
Frequently asked questions
Can I borrow against my equity?
Yes — typically up to 80% LVR. Above that may attract a Low Equity Premium.
