What is Home Equity?
The Home Equity calculation tells you your home equity from a few simple inputs. The figure you are solving for here is the home equity, expressed in INR.
The Home Equity formula

Home equity = Current home value - Outstanding mortgageHere is what each input means:
- Current home value — a money amount. Example: ₹80,00,000.
- Outstanding mortgage — a money amount. Example: ₹50,00,000.
How to calculate it step by step
- Write down the current home value (for example, ₹80,00,000).
- Write down the outstanding mortgage (for example, ₹50,00,000).
- Apply the formula above to get your home equity.
- Double-check the result with the Home Equity Calculator.

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
