Asset allocation is one of the most important decisions for any investor. It determines how much of your portfolio should be invested in stocks, bonds, and cash to balance risk and returns. Whether you're a beginner or an experienced investor, our Asset Allocation Calculator helps you create a diversified portfolio suited to your financial goals.

This calculator is designed for users who want to determine the right asset mix based on factors like age, investment horizon, and risk tolerance. With a simple input, you can get a clear breakdown of how your assets should be distributed.

What is Asset Allocation?

Asset allocation is the process of distributing your investments across different asset classes such as:

  • Stocks (Equities) – Higher potential returns but come with more risk.
  • Bonds (Fixed Income) – Lower risk than stocks, offering steady returns.
  • Cash (or Cash Equivalents) – The safest but offers the lowest returns.

Proper asset allocation reduces investment risks and helps achieve financial stability.

The 100 minus Age Rule is often used for asset allocation, meaning a 30-year-old should have 70% stocks (100-30 = 70).

Asset Allocation Calculation Formula

The standard formula for asset allocation is:

Stocks Allocation (%) = 100 – Investor’s Age

Bonds Allocation (%) = (100 - Stocks Allocation) * 0.75

Cash Allocation (%) = (100 - Stocks Allocation) * 0.25

For example, if you are 40 years old:

  • Stocks = 100 - 40 = 60%
  • Bonds = (100 - 60) * 0.75 = 30%
  • Cash = (100 - 60) * 0.25 = 10%

What is the 12 20 80 Asset Allocation Rule?

The 12 20 80 rule is an investment strategy where:

  • 12% goes into risk-free assets (Cash or Savings)
  • 20% in moderate-risk assets (Bonds, Mutual Funds)
  • 80% in high-risk assets (Stocks, ETFs, Crypto)

This rule is for aggressive investors looking for high returns over a long period.

What is the 4% Rule for Asset Allocation?

The 4% rule suggests that retirees should withdraw 4% of their total portfolio annually to ensure they don’t run out of money. This rule is based on a portfolio consisting of 60% stocks and 40% bonds for long-term sustainability.

What is the 70/30 Rule in Stocks?

The 70/30 asset allocation rule means:

  • 70% in Stocks – For high growth potential
  • 30% in Bonds/Cash – For safety and stability

This allocation is ideal for investors with moderate risk tolerance who want a balance between growth and security.

This will give you a general allocation based on traditional investment strategies.
