Quick guide
How to use this calculator
- Enter amounts from the same property scenario and use consistent periods and units.
- Use visitor-entered rates and allowances from your own documents rather than assuming a local rule.
- Review the component results and the calculator-specific decision boundary before acting.
Calculation method
Calculation method
Each person's deposit and refund share follows their entered contribution weight; total deductions are allocated using the same basis unless the household enters different weights elsewhere.
Entered fixed decimals remain exact through rational arithmetic. Planar distance outputs that require square roots use bounded numerical evaluation. Values round only for display, and unsupported or undefined states return an explicit message.
Worked example
Worked example
Split a 3,000 deposit and a 2,700 refund among contributors with weights 50, 30, and 20.
Each person's deposit and refund share follows their entered contribution weight; total deductions are allocated using the same basis unless the household enters different weights elsewhere.
Supported inputs
Precision and limits
International scope
No currency, market price, interest rate, tax, tenancy rule, planning code, lender policy, or measurement definition is supplied automatically.
Scenario, not a decision
Results are arithmetic scenarios from visitor-entered values—not an appraisal, loan approval, legal interpretation, planning determination, forecast, or professional recommendation.
Precision and privacy
Inputs accept bounded plain decimals and remain in this browser. The engine prevents invalid denominators and misleading non-finite results.
Calculator-specific boundary
Deposit ownership and deduction responsibility can differ from contribution weights. Use a documented household agreement and the actual deposit statement. If exact shares do not divide into 0.01 units, the largest discarded fraction receives the remainder, with person order breaking a tie.
