Asset Allocation Calculator
Calculate your ideal portfolio asset allocation based on age, risk tolerance, and investment goals.
About this tool
An asset allocation calculator helps you determine the optimal mix of stocks, bonds, and other investments for your portfolio based on your personal circumstances. This balance is crucial because it directly affects both your potential returns and risk exposure—the right allocation can help you reach your financial goals while staying comfortable with market volatility, whereas a poorly matched portfolio can lead to either excessive losses or insufficient growth.
To use the calculator, you input key factors like your age, investment timeline, risk tolerance, and financial goals. The tool then applies established allocation models to recommend specific percentages for different asset classes. Typical users include young professionals building their first portfolio, people nearing retirement who need a more conservative approach, and investors who want a data-driven alternative to guessing their allocation proportions.
Keep in mind that the recommendations are based on general investment principles and historical data—your personal situation may warrant adjustments based on existing holdings, income stability, or specific life events. The calculator provides a solid starting point for discussions with a financial advisor, but it is not personalized financial advice and does not account for tax implications or individual circumstances that only a professional can evaluate.

Code Implementation
def calculate_allocation(age: int, risk: str, goal: str) -> dict:
# Base stock percentage using 110-age rule
base_stock = max(10, 110 - age)
# Adjust for risk tolerance
adjustments = {"conservative": -15, "moderate": 0, "aggressive": 15}
base_stock += adjustments.get(risk, 0)
# Adjust for goal
goal_adj = {"retirement": 0, "growth": 10, "income": -10, "preservation": -20}
base_stock += goal_adj.get(goal, 0)
base_stock = max(5, min(95, base_stock))
bonds = max(5, 100 - base_stock - 5)
cash = 100 - base_stock - bonds
return {"stocks": base_stock, "bonds": bonds, "cash": cash}
# Example
result = calculate_allocation(age=35, risk="moderate", goal="retirement")
