Calculator Inputs
Example Data Table
| Asset | Current Value | Target Weight | Example Note |
|---|---|---|---|
| Equities | 55,000 | 50% | Overweight position before rebalancing. |
| Bonds | 25,000 | 25% | Near target allocation. |
| Real Assets | 12,000 | 15% | Needs additional capital. |
| Cash | 8,000 | 10% | Acts as the liquidity buffer. |
Formula Used
Current Weight = Asset Current Value ÷ Total Current Portfolio Value × 100
Normalized Target Weight = Asset Target Input ÷ Sum of Target Inputs × 100
Target Value = Investable Portfolio After Fees × Normalized Target Weight
Trade Amount = Target Value − Current Value
Estimated Fees = Gross Trade Value × Fee Rate + Number of Trades × Fixed Fee
Turnover Ratio = Gross Trade Value ÷ Total Current Portfolio Value × 100
The calculator runs a short fee-estimation loop so target values reflect transaction costs more realistically before final trades are shown.

FAQs
1. What does this calculator actually solve?
It compares current holdings against target allocations, then estimates buy or sell amounts needed to restore the intended mix after fees, rounding, and cash adjustments.
2. Why are my target weights normalized?
Normalization protects the calculation when entered weights do not total exactly 100%. The tool rescales them proportionally so every asset still reflects your intended relative importance.
3. What is threshold-triggered rebalancing?
This mode checks whether any allocation drift exceeds your chosen limit. If no asset breaches the threshold, the calculator keeps all trades at zero and preserves current holdings.
4. How are transaction costs included?
The tool estimates percentage-based fees on gross trading volume and adds a fixed charge for each executed trade. It then adjusts investable value before showing final targets.
5. What happens if I enter a withdrawal?
A negative cash flow reduces the amount available for post-trade allocation. That usually increases required sales and lowers target values across the portfolio.
6. Why use a minimum trade size?
Minimum trade filters remove tiny orders that may be impractical or too costly. This is useful when brokerage fees or operational constraints make small adjustments inefficient.
7. What does trade rounding do?
Trade rounding snaps each recommendation to a chosen unit, such as 50 or 100 currency units. It helps match internal policy, trading lot preferences, or reporting standards.
8. Can I use this for retirement or multi-asset accounts?
Yes. It works for any asset mix where you know current values and desired weights. You should still review tax rules, account restrictions, and execution timing separately.
