Net Owned Fund Calculator for NBFCs

TL;DR

This calculator applies the Reserve Bank’s net owned fund formula, not an accounting one. It builds owned funds from paid-up capital, free reserves and the securities premium account, then removes accumulated losses, deferred revenue expenditure and intangible assets. From that base it deducts exposure to group and subsidiary companies only to the extent it exceeds ten per cent of owned funds — and the ten per cent is measured on owned funds after the first deductions, which is the step in-house computations most often get wrong. It deliberately publishes no minimum threshold: the applicable amount depends on your registration category and scale-based tier and has been subject to a phased increase, so confirm it against the current Master Direction. This is an estimate from figures you enter and carries no UDIN.

Net Owned Fund Computation

The Reserve Bank’s formula, in the order it applies. Owned funds first, then the group exposure deduction — measured against owned funds after the first deductions, which is the step most in-house workings get wrong.

Enter figures in
STEP 1 · WHAT BUILDS OWNED FUNDSFrom the audited balance sheet
STEP 2 · DEDUCT TO REACH OWNED FUNDSEnter as positive figures
STEP 3 · GROUP AND SUBSIDIARY EXPOSUREInvestment and lending, aggregated — not tested separately

The tool can only deduct what you have identified. The relationship that makes a counterparty part of the group is rarely visible from a ledger account name. Map the group structure before entering figures.

COMPUTATION OF NET OWNED FUND

Reserve Bank of India formula · as on · format mirrors a CA computation schedule
ParticularsAmount (₹)
Preview only. This computation is an estimate from the figures entered above. It is not drawn from audited accounts, carries no UDIN, and the Reserve Bank will not accept it in place of a certificate issued by a practising chartered accountant.

This tool publishes no minimum threshold, deliberately. The amount that applies depends on the category your company is registered in and where it sits under scale-based regulation, and the requirement has been subject to a phased increase. A figure stated here and left unrevised would be worse than none, because a director might plan against it. Confirm the amount applying to you against the current Master Direction before treating any shortfall or headroom as real.

⚠️ Four things in-house computations get wrong

  1. Taking the ten per cent on the wrong base. It is measured on owned funds after the step 2 deductions, not on the balance sheet total and not on the sub-total before them. Any other base overstates the allowance and therefore the result.
  2. Deducting the whole group exposure. Only the excess over the allowance is deducted. Exposure at or under the line produces no deduction at all.
  3. Testing investment and lending separately. They are aggregated. Two exposures individually under the line can exceed it together.
  4. Missing a group relationship. Identification, not arithmetic, is where this computation fails. Build the group structure chart first; it is also what supports the deduction when the regulator reads it.
A filing needs this figure certified, not calculated.
Patron builds the computation from audited accounts, with a reserve schedule establishing which reserves are genuinely free and a group structure chart supporting the exposure deduction, signed with a UDIN in the form the application or annual return requires.

How This Calculator Applies the RBI Formula

This calculator applies the Reserve Bank’s formula rather than an accounting one. It builds owned funds from paid-up capital, free reserves and the securities premium account, then removes accumulated losses, deferred revenue expenditure and intangible assets. From that base it deducts exposure to group and subsidiary companies above ten per cent of owned funds. What remains is net owned fund. The order matters: the ten per cent is measured against owned funds after the first set of deductions, not against the balance sheet total, and computing it the other way overstates the result.

The formula in sequence. Paid-up capital + free reserves + securities premium − accumulated losses − deferred revenue expenditure − intangible assets = owned funds. Then owned funds − (group and subsidiary exposure in excess of 10% of owned funds) = net owned fund.

Deductions for Group Company Exposure

The deduction for group exposure is where most in-house computations stop short. It covers investment in shares of group companies and subsidiaries, and lending or advances to them, taken together rather than separately. The difficulty is identification rather than arithmetic, because the connection making a counterparty part of the group is rarely visible in a ledger account name. The calculator asks you to enter the exposure you have identified; it cannot find the ones you have not. Mapping the group structure before entering figures is the step that decides whether the result is meaningful.

Comparing Your Result With the Threshold You Must Meet

Compare the result against the minimum that applies to your company rather than against a general figure. The applicable amount depends on the category the company is registered in and on where it sits under scale-based regulation, and the requirement has been subject to a phased increase. This tool does not carry those amounts, deliberately: a threshold published here and left unrevised would be worse than none, because a director would plan against it. Confirm the figure applying to you against the current Master Direction before treating any shortfall or headroom as real. Where the company sits close to its floor, the sensible step is to model the position before the year end rather than discover a shortfall in the audited accounts. Remedying one after the fact usually means fresh capital on a deadline.

Certify Your Net Owned Fund for the RBI File

Certifying the figure for a filing means evidencing the whole chain. Audited accounts supply the base, a reserve schedule establishes which reserves are genuinely free, and a group structure chart supports the exposure deduction so the regulator can follow it. The company confirms in writing that all group exposures have been disclosed. A practising chartered accountant then signs with a UDIN, in the form the registration application or the annual return requires. The working papers behind the mapping are retained. A regulator asking about a movement between years wants to see how each was arrived at rather than being given two totals and asked to accept the difference.

How This Tool Is Used on Our Service Pages

This calculator sits inline on the net owned fund certificate page, which is the only service page in the cluster where the computation applies. That page carries what the tool leaves out: the statutory basis for each deduction, what the registration and annual filings expect, and why the certified figure sits below balance sheet net worth. That page also carries the filing forms the certificate has to fit, which a calculator cannot supply. Between them they cover the computation and the compliance it feeds. The net owned fund certificate for NBFC page carries the filing requirements this calculator stops short of.

Adjacent to this computation. Where the reader wants the Companies Act figure rather than the RBI one, the company net worth calculator applies the section 2(57) definition, and the net worth certificate for company page sets out that engagement. The two measures are not interchangeable and a filing will name which one it wants.

Frequently Asked Questions About Net Owned Fund

Net owned fund is the Reserve Bank's own measure for non-banking financial companies, not an accounting one. Owned funds are built from paid-up equity capital, free reserves and the securities premium account, less accumulated losses, deferred revenue expenditure and other intangible assets. Net owned fund is then owned funds reduced by investment in and lending to group and subsidiary companies to the extent that exposure exceeds ten per cent of owned funds. Balance sheet net worth carries none of those deductions, which is why the certified figure normally sits below it.
Because the Reserve Bank's formula defines it that way. The ten per cent is taken on owned funds after the first set of deductions has already been made, not on the balance sheet total and not on owned funds before those deductions. Computing it on the wrong base overstates the permitted allowance and therefore overstates net owned fund. The calculator shows the permitted allowance as its own line so the base it was taken on is visible.
Investment in the shares of subsidiaries and companies in the same group, together with loans, advances and any other lending to them. The two are aggregated rather than tested separately. The hard part is identification, not arithmetic: the relationship that makes a counterparty part of the group is rarely visible from a ledger account name. Map the group structure before entering figures, because the tool can only deduct the exposure you have identified.
The applicable amount depends on the category your company is registered in and where it sits under scale-based regulation, and the requirement has been subject to a phased increase. This tool deliberately does not publish a figure: a threshold stated here and left unrevised would be worse than none, because a director might plan against it. Confirm the amount that applies to you against the current Master Direction, or ask us, before treating any shortfall or headroom as real.
Model the position before the year end rather than discovering a shortfall in the audited accounts. A shortfall found after the fact usually means raising fresh capital against a deadline. Where group exposure is what is pulling the figure down, the timing and structure of that exposure is often the lever, and it is easier to act on before the balance sheet date than after it.
Audited accounts supply the base. A reserve schedule establishes which reserves are genuinely free. A group structure chart supports the exposure deduction so the regulator can follow it. The company confirms in writing that all group exposures have been disclosed. The chartered accountant then signs with a UDIN in the form the registration application or the annual return requires, and the working papers behind the mapping are retained.
No. It is an estimate from figures you type in. A filing needs a certificate from a practising chartered accountant, drawn from audited accounts, in the prescribed form and carrying a UDIN. A regulator asking about a movement between two years wants to see how each figure was arrived at, not two totals and a difference.
No. Only the excess over ten per cent of owned funds is deducted. If total group and subsidiary exposure sits at or under that line, net owned fund equals owned funds. The calculator shows both the permitted allowance and the excess, so it is clear whether any deduction arose at all.
