Portfolio target allocation and rebalancing
Compare holding values with chosen targets and calculate arithmetic buy or sell amounts after a cash addition.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
target value = (current total + new cash) × target share; trade amount = target value - current value
You choose the holdings and target allocation. No security selection, risk assessment, live quotes, tax treatment or investment advice. Fractional trades ignore lot sizes, settlement, fees and capital gains. New cash may not prevent sales when matching exact targets. Use your own records for the same scope and period. Example figures are illustrative, not industry benchmarks. Results exclude income taxes and any cost you have not entered. Check the result before pricing work or committing resources.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Holdings and your chosen targets: Enter matching rows from your records; add or remove rows as needed.
- Holding or asset class: Use the matching measured quantity, time log, schedule or clearly stated estimate. Zero means intentionally none; an unknown amount is not zero.
- Current holding value (selected currency): Use a supplier quote, invoice, payroll record or allocated cost for the exact job or period named here. Include this amount only once.
- Your target share (%): Enter a percentage from your records or an explicitly chosen scenario. No typical or recommended rate is supplied.
- New cash to allocate (selected currency): Use a supplier quote, invoice, payroll record or allocated cost for the exact job or period named here. Include this amount only once.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Portfolio after cash addition is $11,000.00 for the illustrative inputs below.
Example inputs
- Holdings and your chosen targets
- Holding or asset class: Asset A
- Current holding value: $6,000.00
- Your target share: 50.00 %
- Holding or asset class: Asset B
- Current holding value: $4,000.00
- Your target share: 50.00 %
- New cash to allocate: $1,000.00
- Portfolio after cash addition
- $11,000.00
- Total modeled purchases
- $1,500.00
- Total modeled sales
- $500.00
- Positive trade amounts are purchases; negative amounts are sales. These are arithmetic differences, not recommendations.
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Compare holding values with chosen targets and calculate arithmetic buy or sell amounts after a cash addition. Inputs come from your own records and stated assumptions; no rates or legal limits are looked up.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
