Asset Allocation & Portfolio Rebalancing Calculator
Strategic framework, drift auditing, and tax-efficient cash-flow executionUse this asset allocation calculator to check how your investments are distributed across Equity, Debt, Gold, Cash and Alternative assets. Compare your current portfolio with your target asset allocation, calculate portfolio drift, review your equity-to-debt ratio, and estimate the amount required to rebalance your portfolio.
Unifies scattered Demat accounts, EPF/PPF, bank deposits, and gold holdings into a consolidated balance sheet to reveal your true aggregate equity-to-debt exposure.
Market runs silently distort asset weights over time (portfolio drift). Left unchecked, an intended 60% equity portfolio can inflate to 80%, unintentionally multiplying your market downside.
Identifies underweight assets and routes your fresh monthly SIP or bonus inflows directly into them first, restoring target proportions without triggering taxable capital asset sales.
The calculator also supports cash-flow-first portfolio rebalancing, allowing you to see how fresh SIP contributions or new investment capital can be directed toward underweight asset classes before considering the sale of existing investments.
How to Use the Asset Allocation Calculator
1 Enter Your Current Portfolio
Enter the current market value of your investments across different asset classes, including stocks, equity mutual funds, ETFs, EPF, PPF, FDs, bonds, gold, cash and other investments.
The calculator combines these holdings into one portfolio so you can see your overall asset allocation rather than evaluating each investment separately.
2 Set Your Target Asset Allocation
Enter the percentage you want to allocate to each asset class. Your target allocation should add up to 100%. For example:
Your target allocation should reflect your investment horizon, financial goals, risk tolerance and overall financial circumstances.
3 Calculate Portfolio Drift
Portfolio drift shows how far your current allocation has moved away from your target allocation.
A positive value indicates an overweight allocation, while a negative value indicates an underweight allocation.
For example, if your target equity allocation is 60% but equity currently represents 70% of your portfolio, your equity allocation has a +10 percentage-point drift.
4 Calculate the Rebalancing Amount
The calculator compares the current value of each asset class with its target value:
The difference between the current value and target value indicates whether an asset class is overweight or underweight and estimates the amount that would need to be shifted to move the portfolio closer to its target.
What Is Portfolio Rebalancing?
Portfolio rebalancing is the process of bringing your investment portfolio back toward a chosen target asset allocation after market movements cause the proportions of different assets to change.
For example, suppose your portfolio initially has 60% equity and 40% debt. If equity performs strongly, equity may eventually represent 70% of the portfolio. Your portfolio has then drifted away from the original allocation.
Rebalancing can involve directing new investments toward underweight asset classes or, when appropriate, reducing an overweight allocation.
Can You Rebalance a Portfolio Without Selling?
Yes, in some situations.
If you regularly invest through SIPs or have fresh capital available, you can direct new money toward underweight asset classes instead of immediately selling existing investments.
For example, if equity is above its target allocation while debt is below target, a new investment can be directed toward debt until the portfolio moves closer to its desired allocation.
Equity-to-Debt Allocation
Your equity-to-debt ratio is an important part of overall portfolio allocation.
Equity investments can provide long-term growth potential but generally experience greater price fluctuations. Debt and fixed-income investments can play a stabilising role by offering capital preservation and steady income generation. Balancing these two components helps align your portfolio's risk level with your time horizon and investment objectives.
Equity, Debt, Gold and Cash Allocation
A diversified investment portfolio may contain several asset classes, including equity, debt, gold and cash.
Each asset class can serve a different role within an overall portfolio structure. Reviewing them together helps you understand your total portfolio exposure rather than looking at individual investments in isolation.
For example, stocks, equity mutual funds and equity ETFs can be considered when reviewing overall equity exposure. EPF, PPF, FDs, bonds and other fixed-income holdings can be considered when reviewing debt exposure.
Gold holdings can include instruments such as gold ETFs, physical gold and other eligible gold investments, while cash represents liquid funds held for short-term needs or emergencies.
Asset Allocation Example: ₹50 Lakh Portfolio
Consider an illustrative ₹50 lakh portfolio:
The calculator compares the current allocation with the target allocation and identifies the asset classes that are overweight or underweight.
If fresh money is available through a monthly SIP or lump-sum investment, that capital can potentially be directed toward underweight asset classes before considering the sale of existing investments.
Frequently Asked Questions
1. What is an asset allocation calculator?
An asset allocation calculator helps you determine how your portfolio is distributed across asset classes such as equity, debt, gold and cash and compare that distribution with a target allocation.
2. What is a portfolio rebalancing calculator?
A portfolio rebalancing calculator compares your current portfolio allocation with your target allocation and estimates the amount that may need to be bought, reduced or redirected to move closer to the target.
3. How do I calculate portfolio drift?
Portfolio drift is calculated by subtracting the target allocation from the current allocation:
A positive value indicates an overweight allocation, while a negative value indicates an underweight allocation.
4. Can I rebalance my portfolio using SIPs?
Yes. Fresh SIP contributions can sometimes be directed toward underweight asset classes instead of selling existing investments. Whether new contributions are sufficient depends on the portfolio size, current allocation and amount of new investment.
5. What should my equity-to-debt ratio be?
There is no single equity-to-debt ratio that is suitable for every investor. The appropriate target depends on factors such as investment horizon, financial goals, risk tolerance and ability to tolerate losses.
6. Should I sell investments to rebalance my portfolio?
Not necessarily. Depending on the portfolio and available fresh capital, you may be able to move closer to your target allocation by directing new investments toward underweight asset classes. Selling existing investments may still be appropriate in some situations.
7. Does rebalancing reduce investment risk?
Rebalancing can help maintain the portfolio risk characteristics associated with a chosen asset allocation, but it cannot eliminate investment risk or guarantee against losses.
8. Is this calculator financial advice?
No. This calculator provides mathematical estimates based on the information entered by the user. Illustrative allocations and calculations should not be treated as personalised investment, tax or financial advice. Consider your individual circumstances and consult a qualified professional where appropriate.
