How much corpus do you actually need before moving back to India?

Assuming you are an NRI in the US, mid-30s to late-40s, with a stable job, RSUs vesting, a 401(k) building, and parents in India who are not getting younger. The recurring question in news cycles and group chats is "how much corpus do I really need before moving back." The popular debate keeps landing on round numbers — 5 crore, 8 crore, "next to impossible." Those numbers are useful only as conversation starters. The honest answer is that the corpus you need is a function of four variables, three of which are personal to you.

This article walks through the four variables using primary-source rules for the tax and FEMA pieces, and clearly labelled planning assumptions for the numerical pieces, so the framework is portable to your own spreadsheet.

1. The four variables that actually decide the answer

You need a corpus that, after Indian tax on its income and after inflation, can fund your post-return lifestyle for your chosen horizon.

The four inputs are:

1. Annual post-return spend           (your number)
2. Post-tax real return on corpus     (assumption, see Section 3)
3. Withdrawal horizon                 (perpetual vs. finite)
4. Residual India income              (consulting, rentals, dividends)

Everything else — the city you pick, the school you pick, whether you keep working — flows into variable 1 (spend) or variable 4 (residual income). The math itself is mechanical. The discipline is in being honest about variable 1.

2. Annual post-return spend — the variable people lie to themselves about

There is no official "what an upper-middle-class family in Bengaluru spends" figure. India's official Consumer Price Index is published by the Ministry of Statistics and Programme Implementation (MoSPI) and reflects the inflation rate your spend will compound at year over year, but the absolute spend number is something you have to build line by line.

The ranges below are observed anecdotal market ranges that returnee families typically discuss in private forums and broker estimates. They are not primary-source figures. Treat them only as a sanity-check on your own line-item budget:

Rent, 3BHK, tier-1 good locality        55-90k/month       (illustrative)
Domestic help (cook + cleaner + driver) 25-45k/month       (illustrative)
Two kids, mid-tier international school 30-80k/month per kid (illustrative)
Health insurance, family of 4           60k-1.5L/year       (illustrative)
Car (depreciation + fuel + maintenance) 15-30k/month       (illustrative)
Discretionary (travel, eating out)      40-80k/month       (illustrative)

Many returnee families discuss numbers in a 2.5 lakh to 6 lakh per month all-in range depending on schooling and lifestyle. That translates to roughly 30 lakh to 72 lakh per year before any inflation. The point is not to anchor on someone else's number — it is to build your own line-item budget before doing any corpus math, because everything downstream multiplies off this.

3. Post-tax real return — the variable the news articles skip

The corpus does not earn its gross yield. It earns gross yield minus India tax on the income minus inflation. Two rules drive the tax piece.

Residential status. Under Section 6 of the Income-tax Act, 1961, you start as a Non-Resident, can transition through Resident but Not Ordinarily Resident (RNOR) under the tests in Section 6(6), and eventually become Resident and Ordinarily Resident (ROR). The scope of what India can tax is defined in Section 5: a non-resident is taxed on India-source and India-received income only; an ROR is generally taxed on worldwide income. RNOR sits in between, with foreign income not received in India and not derived from a business controlled from India generally outside the Indian net.

Post-ROR taxation by asset class. Treat the list below as direction, not gospel — Finance Act amendments move specific rates and regimes from year to year, and your actual treatment depends on facts that should be confirmed with a CA:

Indian equity MF / listed equity     (long-term capital gains regime)
Indian debt MF                       (taxed at slab under the post-2023 amendment)
Bank fixed deposit interest          (slab)
NRE FD interest                      (exempt while you are a person resident outside
                                      India under FEMA; redesignation required on return)
US 401(k) / IRA withdrawals          (treatment can be nuanced; DTAA relief
                                      generally available)
US brokerage dividends / capital gains (treatment can be nuanced; DTAA relief
                                      generally available)

The India-US double-tax relief pathway flows through Article 25 of the India-US treaty (relief from double taxation) read with Section 90 of the Income-tax Act, with the mechanics in Rule 128 and the filing requirement in Form 67. Section 91 is the non-treaty relief route and does not apply where a treaty is in force.

For corpus-replacement planning, a working assumption many returnee planners use is a post-tax real return in the 2% to 4% range on a balanced portfolio once you are ROR. This is an assumption, not a guaranteed outcome. Higher in good years, lower in flat years. Assuming 7% real returns "because that's what the S&P does long-run" tends to understate the drag from India tax on interest and debt, exchange-rate variability, and inflation differentials.

4. Withdrawal horizon and a working corpus formula

For a perpetual horizon (corpus must outlast you and your spouse, ideally pass to children), a commonly used working rule in personal-finance planning is:

Required corpus ≈ Annual spend ÷ Post-tax real withdrawal rate

This formula is an assumption-driven planning shortcut, not a guarantee of sustainability. Plug in three illustrative scenarios — annual spend in today's rupees, withdrawal rate net of India tax and inflation:

Spend 30L/yr  ·  3% real WR   ≈   10 Cr corpus
Spend 30L/yr  ·  4% real WR   ≈    7.5 Cr corpus
Spend 50L/yr  ·  3% real WR   ≈   16.6 Cr corpus
Spend 50L/yr  ·  4% real WR   ≈   12.5 Cr corpus
Spend 72L/yr  ·  3% real WR   ≈   24 Cr corpus

These are illustrative arithmetic outcomes of the formula, not official benchmarks. They explain where the "5 crore vs 8 crore" debate comes from: 5 Cr at 4% real funds about 20 lakh per year of spend; 8 Cr funds about 32 lakh. Each answers a different lifestyle question.

For a finite horizon — for example, planning to consult or work in India for another decade and only needing the corpus to bridge — the required number drops materially. A finite-horizon depletion model can survive on substantially less corpus, but it then depends on continued earning ability in India.

5. The two rules that change the math the year you land

Two India-side rules can shift the post-tax return in the first one to two resident tax years after return. Both are worth understanding from the primary source.

RNOR (Section 6(6) of the Income-tax Act, 1961). During RNOR years, foreign-source income that is not received in India and is not derived from a business controlled from or profession set up in India is generally not taxed in India. This window typically gives returnees a planning period to consider the timing of US-side actions (RSU sales, brokerage rebalancing, retirement-account drawdowns) before worldwide-income taxation under ROR begins. The exact length of the window depends on the prior-year stay pattern tested under Section 6(6); a CA can compute it from actual travel records.

FCNR / NRE deposit treatment under FEMA, 1999 and the RBI Master Direction on Deposits and Accounts of Non-Residents (FED Master Direction No. 14/2015-16). The RBI Master Direction provides that NRE / NRO accounts are required to be redesignated as resident accounts on change of residential status under FEMA, with prompt notification to the bank. FCNR(B) deposits are generally permitted to continue at the contracted rate of interest until maturity, with onward treatment at maturity governed by the Master Direction and any applicable Income-tax Act provisions on the resulting balances. The exact tax treatment of interest on these instruments after return depends on residential status under the Income-tax Act and should be confirmed with a CA.

The first 18 to 24 months after landing are often described as a high-leverage planning window because several of these timing decisions interact. Much of the value of careful sequencing — when to convert NRE to resident, when to mature FCNR, when to trigger US capital gains — is captured or lost in this window.

6. So what is the corpus number?

There is no single right answer. There is your right answer, which comes from your own line-item budget and your own planning assumptions:

Your corpus ≈ (Your honest annual spend in today's INR)
              ÷ (Your assumed post-tax real return, illustratively 2-4%)

A buffer of 12 to 18 months of post-return spend held in an Indian liquid fund or short-duration debt fund — separate from the long-term corpus — is a commonly used planning convention for landing-year transition costs (deposits, moving, healthcare setup, vehicle). This is a planning convention, not an official rule.

If the corpus is short by 1 to 3 crore relative to a perpetual-horizon target, the realistic options that returnee families typically consider are:

1. Stay 2-3 more years in the US to close the gap
2. Plan a finite-horizon return with active India earning
3. Reduce target spend (smaller city, public schooling, smaller car)
4. Combine: smaller corpus + part-time consulting in India

The "next to impossible" framing in some news coverage describes the perpetual-corpus case at tier-1 city, international school, with no India income. It is a narrower case than how most actual returnees have made the move work in practice.

7. The decision is the model, not the headline number

Building the four-variable model in a spreadsheet — real spend line-items, real portfolio mix, an explicit assumption for post-tax real return, an explicit horizon — produces a corpus number that is meaningful for your case. Updating it every six months keeps it tied to reality as inflation and rules drift.

Headline numbers in news articles answer someone else's question. Your question has your own numbers in it.

A note on what this is. This article is one returnee's working notes, not personalised advice. Numbers age. Rules change. The only person who can sign off on your specific case is a qualified cross-border chartered accountant looking at your full facts. Use this as a checklist of questions to take to that conversation, not as the answer.
