How long your income lasts
Drawing rising income from the safe buckets first, against the blended return.
A ₹3,00,00,000 corpus drawing ₹12,00,000 a year — a 4.0% first-year withdrawal rate, rising with 6.0% inflation — sustains your income for 40+ years at a 9.2% blended return. That comfortably clears the 40-year horizon to age 100, still holding ₹13.22 Cr. What decides it is the real return — about 3.2% after inflation — versus how fast you draw. Projection only; real returns and inflation vary.

Your ₹12.00 L/yr income rising at 6.0% inflation.
At 6.0% inflation your annual income needs to rise from ₹12.00 L today to about ₹1.16 Cr by year 40 — which is why the equity bucket has to keep growing.

What if markets fall?
The whole point of the structure: a crash never forces you to sell equity at the bottom.
Cash & liquid
Spent first — never sold in a dip
Holds ₹45.00 L, about 3.8 years of income, so a crash never forces a sale.
Debt & bonds
Refills cash as it empties
Its ₹1.05 Cr debt layer tops up the cash bucket, buying the equity bucket time to recover.
Equity
Left untouched to recover
The ₹1.50 Cr equity bucket rides out the downturn and is only harvested in good years.

Your returns vs typical anchors
Illustrative long-term averages — not live rates or guarantees.
savings / liquid funds — typical
debt funds / bonds — typical long-term
equity — illustrative long-term average
Anchors (cash ~6%, debt ~8%, equity ~11%) are typical long-term / illustrative figures, not guarantees. Your blended return of 9.2% is the allocation-weighted average that actually drives longevity.
- 4.0% first-year withdrawal rate — ₹1.00 L/month drawn from ₹3.00 Cr.
- Clears the full 40-year horizon, still holding ₹13.22 Cr.
- Real return of 3.2% after inflation is what actually sustains it.
What this means
On a ₹3.00 Cr corpus, drawing ₹12.00 L a year is a 4.0% withdrawal rate. With a 50% equity tilt giving a 9.2% blended return — about 3.2% after inflation — the buckets sustain that income past the full 40-year horizon, still holding ₹13.22 Cr at age 100.
Key takeaways
- Success probability: 92% (very high)
- Income sustained: 40+ years (to age 100+)
- Monthly income: ₹1.00 L (₹12.00 L/yr)
- Withdrawal rate: 4.0% of corpus
- Blended return: 9.2% (3.2% real) · 50% equity
Beats sequence risk
Spending from cash first means a market crash never forces you to sell equity at the bottom.
A wage you can see
The cash bucket is years of spending you can point to — calmer than watching one volatile pot.
Growth keeps working
The equity bucket has a decade-plus to compound, fighting the inflation that erodes your income.
Simple refill rule
Top up cash from debt, and debt from equity gains in good years — spend cash and wait in bad ones.
Even in the worst-case band (equity 4%), the buckets sustain income for 26 years— the structure's job is to make that survivable without selling equity low.

Plan the rest of your money life
Size the corpus, add a pension, or turn buckets into systematic withdrawals.
The bucket strategy parks short-term income in safe, low-volatility assets and keeps long-term money in equity, so you never sell stocks in a downturn. Longevity is driven by the blended return across buckets versus inflation-adjusted withdrawals. This calculator grows the whole corpus at a single constant blended return and subtracts each year's rising income — a simplified projection, not a model of every refill, and not financial advice. Real returns and inflation vary, and past performance does not guarantee future returns. The success probability is a transparent reading of your own inputs, not a Monte-Carlo guarantee.

Bucket strategy questions
The bucket strategy splits your retirement corpus into separate pools based on when you'll need the money. A short-term bucket holds cash and liquid funds for near-term expenses, a medium-term bucket holds debt and bonds, and a long-term bucket stays in equity to keep growing. Spending comes from the safe buckets first, giving the equity bucket time to ride out market dips before you touch it.
Two buckets — one safe (cash plus debt) and one growth (equity) — is simpler and easier to maintain. Three buckets adds a middle debt-and-bonds layer between cash and equity, which gives you a smoother glide and a buffer to refill the cash bucket from without selling equity. More buckets mean more rebalancing work; pick the level of structure you'll actually keep up with.
Periodically — often yearly — you top up the cash bucket from the medium-term bucket, and top up the medium-term bucket from equity gains during good market years. In down years you simply spend from cash and leave equity untouched, which is the whole point of the strategy. This calculator models the blended return rather than each refill, so treat it as an estimate of overall longevity.
No. Nothing about splitting a corpus into buckets changes the underlying maths: if withdrawals plus inflation outpace returns for long enough, the corpus depletes. The strategy helps manage sequence-of-returns risk by avoiding forced equity sales in downturns, but real returns, inflation and spending all vary. This tool is a simplified projection, not a guarantee or financial advice.
The complete guide to the bucket strategy
What the bucket strategy is
The bucket strategy structures a retirement corpus around whenyou'll spend the money rather than treating it as one undifferentiated pile. Near-term income sits in cash and liquid funds that won't fall in value, medium-term money sits in debt and bonds, and the long-term portion stays invested in equity where it has decades to compound. You draw income from the safe buckets first, which means a market crash never forces you to sell equity at the worst possible moment.
How the buckets refill
Periodically — often yearly — you top up the cash bucket from the income (debt) bucket, and top up the income bucket from equity gains during good market years. In down years you simply spend from cash and leave equity untouched, which is the whole point. This calculator models the overall blended return rather than each refill, so treat the 40-year-plus longevity it reports as an estimate of overall sustainability, not a month-by-month plan.
What decides how long the income lasts
Longevity comes down to your blended return — here 9.2%, an allocation-weighted average across the buckets — against your inflation-rising withdrawals. A 4.0% first-year withdrawal rate with 6.0% inflation gives a real return of about 3.2%, which is what actually sustains the income. A larger equity slice lifts the blended return and stretches longevity but raises the swings you have to stomach; a larger safe slice does the opposite.
Two buckets or three
Two buckets — one safe (cash plus debt) and one growth (equity) — is simpler to maintain. Three buckets adds a middle income layer between cash and equity, giving a smoother glide and a buffer to refill cash from without selling equity. More buckets mean more rebalancing work, so pick the level of structure you'll actually keep up with. Either way the principle is the same: keep money you'll spend soon out of the market.
Choosing a strategy tilt
A Conservative tilt holds more in cash and debt for a steadier glide and a smaller worst-case drawdown; a Growth tilt holds more equity for higher longevity at the cost of bigger year-to-year swings; Balanced sits in between. The strategy presets here are illustrative reference splits — adjust the sliders to match your own risk tolerance, since the structure only works if you can stick with it through a downturn.
How to read these numbers
Treat the output as a planning estimate. Real returns are not constant, inflation varies, and the refill mechanics between buckets are simplified here into a single blended rate. The return anchors used (cash ~6%, debt ~8%, equity ~11%) and the success probability are typical or illustrative figures — not live rates or guarantees, and past performance does not guarantee future returns. It is a way to compare allocations, spending levels and structures, not a promise about any particular future, and nothing here is financial advice.
