Quick answer: The equity formula is Equity = Assets − Liabilities. For a home in India it becomes Home Equity = Current Market Value − Outstanding Loan. In accounting it is rearranged as Assets = Liabilities + Equity. All three are the same idea seen from different angles.
Key takeaways
- Core formula: Equity = Assets − Liabilities.
- Accounting form: Assets = Liabilities + Equity (the accounting equation).
- Home equity in India = market value − outstanding home loan or LAP.
- Borrowable equity is capped by RBI's loan-to-value limits.
- Always use current values and outstanding balances, not old figures.
The word “equity” appears in home loans, company balance sheets and demat accounts, and in every one of these settings it obeys the same short formula. Once you understand that formula and its variations, you can calculate equity for almost any asset in seconds. This guide explains the equity formula in plain language, shows how it changes shape across contexts, and works through Indian rupee examples so the maths feels concrete.
The core equity formula
At its heart, equity is what remains after debts are settled:
Equity = Total Assets − Total Liabilities
Assets are what you own — a flat, a plot, shares, cash. Liabilities are what you owe — a home loan, a loan against property, broker margin. Subtract the second from the first and the remainder is your equity, expressed in rupees. This single line is the parent of every other equity formula you will ever meet; the rest are just special cases written for a particular situation.
The accounting version: Assets = Liabilities + Equity
Businesses in India, from a small proprietorship to a listed company, present equity through the accounting equation:
Assets = Liabilities + Equity
Rearrange it and you are back to Equity = Assets − Liabilities. On a company balance sheet, this equity is often called shareholders' funds or net worth, and it represents what would be left for the owners if the firm sold everything and cleared every due. The equation must always balance, which is why it is the foundation of double-entry bookkeeping followed under Indian accounting standards.
Home equity formula in India
For the asset most Indians care about — the family home — the formula specialises to:
Home Equity = Current Market Value − Outstanding Home Loan
There is, however, a second number that matters just as much in India: how much of that equity a bank will actually lend against. Because the Reserve Bank of India caps loan-to-value ratios, a Loan Against Property usually releases only 55–75% of the assessed value. So your usable equity is:
Borrowable Equity = (LTV % × Market Value) − Outstanding Loan
You can run both formulas instantly with the free equity calculator, and check the resulting EMI with the loan calculator.
Worked examples for India
Example 1 — Home equity in Hyderabad. Anil's flat is valued at ₹90,00,000 and his outstanding home loan is ₹35,00,000. Home Equity = ₹90,00,000 − ₹35,00,000 = ₹55,00,000. If a bank offers a LAP at 70% LTV, borrowable equity = (0.70 × ₹90,00,000) − ₹35,00,000 = ₹63,00,000 − ₹35,00,000 = ₹28,00,000 of fresh funds.
Example 2 — Owner's equity in a small business. Sunita runs a boutique. Her business assets (stock, fittings, cash) total ₹12,00,000 and her liabilities (supplier dues and a small business loan) total ₹4,50,000. Owner's Equity = ₹12,00,000 − ₹4,50,000 = ₹7,50,000.
Example 3 — Equity in shares. Karan holds a portfolio worth ₹8,00,000 and owes ₹1,50,000 in margin. Equity = ₹8,00,000 − ₹1,50,000 = ₹6,50,000, the figure his broker uses for margin monitoring.
| Scenario | Assets | Liabilities | Equity |
|---|---|---|---|
| Anil — home | ₹90,00,000 | ₹35,00,000 | ₹55,00,000 |
| Sunita — business | ₹12,00,000 | ₹4,50,000 | ₹7,50,000 |
| Karan — shares | ₹8,00,000 | ₹1,50,000 | ₹6,50,000 |
Benefits of knowing the formula
Mastering the equity formula turns vague worries about money into clear numbers you can act on. It lets you judge, before you ever visit a bank, roughly how large a loan a property can support, so you negotiate from a position of knowledge. For business owners it is the quickest health check of net worth, and for investors it explains exactly when a margin call is likely. Because the same formula travels across every asset class, learning it once pays dividends for a lifetime of financial decisions.
Challenges and limitations
The formula is only as reliable as the numbers you feed it. Market value is an estimate that can move with sentiment, and in illiquid Indian property markets the “value” you assume may not be the price a buyer pays. Liabilities can also be understated if you forget accrued interest, penalties or informal dues. And the formula tells you your equity, not how quickly you can convert it to cash — a distinction that matters in an emergency.
Common mistakes to avoid
- Adding instead of subtracting. Equity is assets minus liabilities; mixing up the sign inflates the number wildly.
- Using sanctioned loan, not outstanding. Always subtract the balance you still owe today.
- Ignoring the LTV cap. The gross equity formula and the borrowable-equity formula give different answers; use the right one for the question.
- Double counting assets. Listing the same asset twice, or counting a jointly owned asset in full, distorts equity.
- Forgetting hidden liabilities. Pending EMIs, interest and charges all reduce true equity.
- Stale valuations. An old market value makes even a correct formula produce a wrong result.
Best practices and expert recommendations
- Write down every asset and liability before applying the formula, so nothing is missed.
- Use current, defensible values — a recent valuation report rather than a hopeful guess.
- Keep a gross and a borrowable figure so you never confuse what you own with what you can borrow.
- Recompute after every prepayment, since reducing the loan directly increases equity.
- Cross-check with a calculator to eliminate arithmetic slips on large rupee figures.
- Revisit annually, because both sides of the formula drift over time.
Key takeaway: Every equity formula — personal, accounting or home — is the same subtraction. Learn Equity = Assets − Liabilities once, and you can decode all the rest.
When to use each version of the formula
Because equity wears three outfits — the plain subtraction, the accounting equation and the home-equity special case — it helps to know which one to reach for. Use the plain form, assets minus liabilities, whenever you simply want your net ownership in a single asset or your overall net worth. Reach for the accounting equation when you are reading or preparing a balance sheet, because it keeps the two sides in balance and reveals how a firm has been financed by owners versus lenders. Turn to the home-equity form, paired with the loan-to-value check, whenever a property is involved and borrowing is on the table.
Choosing the right version matters because each answers a slightly different question. A homeowner who applies the gross formula may feel wealthy on paper, yet the borrowable-equity version tells the sober truth about how much a bank will actually hand over. A business owner who tracks the accounting equation each quarter can watch net worth climb as profits are retained and debts are repaid. The discipline of picking the correct lens, then feeding it current and honest figures, is what makes the equity formula genuinely useful rather than merely academic. In practice, most Indian households benefit from calculating all three at least once a year and revisiting them before any major loan, sale or investment decision.
How equity changes over time
Equity is rarely a fixed number; it breathes with your finances. On the asset side, a home may appreciate as the neighbourhood develops, new metro lines open or demand rises, quietly lifting your equity without any effort on your part. On the liability side, every monthly instalment you pay reduces the outstanding principal, so the debt you subtract keeps shrinking. The two forces usually push in the same direction, which is why equity tends to build steadily for disciplined borrowers. Conversely, taking a fresh top-up loan or watching prices soften can pull equity down. Understanding these moving parts helps you time decisions well: sell or refinance when equity is strong, and avoid stacking new debt when it is thin. Reviewing the formula each year keeps you honest about where you truly stand.
Frequently Asked Questions
What is the basic equity formula?
The basic formula is Equity = Total Assets minus Total Liabilities. It measures the value you would keep if you sold every asset and cleared every debt. The same formula applies to homes, businesses and share portfolios.
What is the accounting equation for equity?
The accounting equation is Assets = Liabilities + Equity. Rearranged, it gives Equity = Assets minus Liabilities. Indian businesses use it as the basis of double-entry bookkeeping, and the equation must always balance.
How do I calculate home equity in India?
Subtract your outstanding home loan or LAP balance from the current market value of the property. To find how much you can borrow, apply the lender LTV percentage to the market value and then subtract the outstanding loan.
Why is my borrowable equity lower than my actual equity?
Because the RBI caps loan-to-value ratios, lenders release only a portion of a property value, typically 55 to 75 percent for a Loan Against Property. Your outstanding loan is then subtracted from that capped amount, leaving less than your full equity.
Does the equity formula work for shares?
Yes. For a share portfolio, equity equals the market value of your holdings minus any borrowed margin. Brokers watch this number closely and may issue a margin call if it falls too low.
