Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Share owed by A:
totalExpense*(incomeA/(incomeA+incomeB)) - Share owed by B:
totalExpense*(incomeB/(incomeA+incomeB))
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with Income A = 4000, Income B = 2000, Total shared expense = 600, this calculator returns Share owed by A = 400, Share owed by B = 200.
