Bucket Strategy Calculator
The bucket strategy calculator lets you see the mechanics in action before you commit real money to them. It simulates a 3-bucket retirement plan — cash, income and growth — through a market downturn, and compares it head-to-head against withdrawing from a single, combined portfolio.
What this calculator does
It takes your retirement details — corpus, yearly spending, expected returns and how long your money needs to last — and runs them two ways. First, as a conventional single-pool withdrawal, where every year's spending comes out of the whole portfolio. Then, as a 3-bucket plan, where spending is drawn from a cash bucket first and refilled from income and growth buckets only when markets allow. The output is a side-by-side comparison of balances over time, so you can see in concrete numbers how the bucket structure behaves in an early bear market.
How the bucket strategy works here
The calculator models the three buckets in order. Bucket 1 is cash covering roughly one to three years of spending — the money you actually live on. Bucket 2 holds income and stability assets, sized to cover the middle years. Bucket 3 holds growth assets that fund the long run. In each simulated year the plan spends from Bucket 1 first; in good years it refills Bucket 1 from Buckets 2 and 3, and in bad years it leaves them alone. This is the same logic described in the bucket strategy guide, reduced to numbers.
Inputs you'll need
You'll provide your starting corpus, annual withdrawal amount, time horizon, the expected return and volatility of the growth bucket, the expected return of the income bucket, and how much of your portfolio sits in cash. Most inputs have sensible defaults based on your portfolio, and you can adjust everything to match your own situation. Values work in any currency, including ₹.
How the calculation works
Year by year, the calculator applies returns to each bucket, takes out that year's spending, and decides whether to refill cash from the other buckets. In the conventional scenario, the same spending is taken from one combined portfolio. The comparison isolates the effect of the bucket structure: same withdrawals, same returns, same horizon — the only difference is how the money is organised. Because the simulation focuses on the mechanics rather than luck, you can see clearly when and why the two approaches diverge.
A worked example
For illustration, suppose you have ₹2 crore, spend ₹10 lakh a year and plan for 25 years. In the conventional plan, every year's spending is sold from the combined balance regardless of market conditions. In the bucket plan, the first few years of spending sit in cash, the next several in income assets, and the rest grows untouched. If a steep equity loss arrives early, the conventional portfolio takes the hit and sells low, while the bucket plan simply spends cash and never touches the growth bucket that year. Over time the two balances diverge — and the calculator shows exactly where and why. These figures are illustrative and hypothetical, not promises of any outcome.
What the results mean
The results chart tracks both balances across the full horizon, so you can see when the bucket plan pulls ahead and when it falls behind. A year-by-year breakdown shows where each year's spending came from and what each bucket held. Remember that the bucket plan typically sacrifices some long-term growth for short-term safety, so the point of the comparison isn't to declare a winner — it's to show you the trade-off in your own numbers before you live with it.
Assumptions and limitations
The calculator is a simplified model. It assumes returns and spending are steady and periodic, ignores taxes, fees and inflation unless you set them, and cannot foresee real-world crises or your spending choices. It also cannot guarantee outcomes — a long enough bear market can drain any plan. Use it to understand the mechanics and compare strategies, then stress-test the result with aMonte Carlo simulation for a fuller picture.
Using it in India
The calculator handles ₹ (or any currency) naturally. For a real Indian plan, Bucket 1 might be a savings account or sweep-in deposit, Bucket 2 debt funds or fixed deposits, and Bucket 3 equity mutual funds.

Understandingsequence-of-returns risk is also a useful companion before you settle on a withdrawal plan.

Frequently Asked Questions
What does the bucket strategy calculator do?
It simulates a 3-bucket retirement plan — cash, income and growth — year by year, and compares it side by side with a conventional single-pool withdrawal plan. You enter your corpus, spending and assumptions, and it shows how the two balances diverge over time, especially through an early market downturn.
What is the difference between bucket and conventional withdrawals?
A conventional plan takes every year's spending out of one combined portfolio, so a downturn forces you to sell units at the bottom. The bucket plan draws from a cash bucket first and only refills it from income and growth buckets in good years, so long-term assets are rarely sold during bad markets. Both spend the same amount; they differ only in where the money comes from.
How much cash should I keep in bucket 1?
A common guideline is one to three years of living expenses. Too little and a downturn can reach your growth assets quickly; too much and you sacrifice long-term returns. Start with two to three years and adjust based on your spending flexibility, then test different levels in the calculator to see how each performs.
Does the calculator guarantee outcomes?
No. It is a simplified model of how the mechanics work — returns and spending are based on the assumptions you enter, and real life includes taxes, fees, inflation surprises and unpredictable markets. Use it to understand the trade-offs and compare strategies, then stress-test the result with a Monte Carlo simulation.
Can I use it for Indian retirement planning?
Yes. The calculator works in any currency, including ₹. For a real Indian plan, Bucket 1 might be a savings account or sweep-in deposit, Bucket 2 debt funds or fixed deposits, and Bucket 3 equity mutual funds.
