Formula Used

1. Current Portfolio Value
Current Portfolio Value = Sum of all current asset amounts
2. Projected Portfolio Value
Projected Portfolio Value = Current Portfolio Value + Contribution − Withdrawal
3. Current Weight
Current Weight (%) = (Current Asset Amount ÷ Current Portfolio Value) × 100
4. Normalized Target Weight
Normalized Target Weight (%) = (Entered Target Weight ÷ Total Entered Targets) × 100
5. Target Amount
Target Amount = Projected Portfolio Value × (Normalized Target Weight ÷ 100)
6. Required Trade
Required Trade = Target Amount − Current Asset Amount
7. Drift
Drift (%) = Current Weight − Target Weight
8. Estimated Turnover
Turnover (%) = 0.5 × Sum of Absolute Required Trades ÷ Projected Portfolio Value × 100

FAQs

1. What is target allocation?

Target allocation is your planned percentage split across asset classes. It helps keep risk, return expectations, and diversification aligned with your long-term investment strategy.

2. Why does the calculator normalize targets?

If entered target percentages do not total 100%, the calculator rescales them proportionally. This preserves your relative intent while producing a complete allocation model.

3. What does drift band mean?

A drift band is the tolerance you allow before rebalancing. If an asset’s current weight moves beyond that range, the calculator flags it as outside band.

4. Why might the cash row require a trade?

Cash is treated like any other asset class here. If your target cash percentage differs from your current cash holding, the tool shows the amount needed to rebalance it.

5. Should I include trading fees?

Yes. Even small fees can affect efficient rebalancing, especially for frequent adjustments or smaller portfolios. The estimate helps you understand the cost of execution.

6. Can this calculator support contributions and withdrawals?

Yes. Contributions increase the projected allocation base, while withdrawals reduce it. That lets you test rebalancing needs before your next planned portfolio change.

7. How often should I rebalance?

Many investors rebalance on a schedule, such as quarterly or yearly, or when drift exceeds a threshold. The better choice depends on costs, taxes, and discipline.

8. Does this calculator provide investment advice?

No. It is an educational planning tool. Use it to organize decisions, then review assumptions, tax impacts, and suitability before placing actual trades.
