是什么 Equity Calculator?

▾

Home equity is the portion of property value you own: current market value minus outstanding mortgage balance. Equity grows as you repay the mortgage and as property values rise.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

常见问题

▾

Does equity increase automatically?

Two ways: (1) Paying principal reduces mortgage balance. (2) Home price appreciation increases value. Both grow equity. Price drops reduce it (negative equity possible).

What's the maximum I can borrow against equity?

Typically 80–85% LTV for HELOC or home equity loan. So a $300k home with $100k equity may let you borrow $140k (50% LTV cushion).

Is accessing equity via HELOC a good idea?

It's a tool. Low rates make it attractive for debt consolidation, repairs, or investments. But spending equity on consumption is risky—you're leveraging your home.

Regional Guides

US▾

HELOC standard at 80% LTV. Interest rates variable; typically prime + margin (7–9% today). Can draw and repay flexibly during draw period.

UK▾

Equity release (lifetime mortgages) common for retirees; expensive (5–7% rates). Standard remortgage to release equity is cheaper if possible.
