Guidance
Keep measurement units consistent
A result can be wrong even when the arithmetic is right if miles and kilometers, hours and minutes, ounces and pounds, or monthly and annual amounts are mixed.
Run a second scenario before deciding
Use the first result as a baseline, then change the variable you can control. Comparing two realistic scenarios usually provides more useful information than one isolated number.

How to use it
Start with the values requested by the Bill Split tool and replace any sample numbers with figures from your actual situation. Split a bill by people with tax, tip and optional unequal share weighting. Keep every entry in the unit and time period shown beside the field, then review the highlighted result together with the supporting outputs.
What the results mean
The highlighted result is the main answer produced by the Bill Split calculation. The additional result cards provide context, components, ratios, costs, quantities, or comparison values that help explain why the primary result changed when you adjusted an input.
How the calculation works
The Bill Split tool applies the arithmetic or modeling relationship described by the requested inputs and supporting outputs. Split a bill by people with tax, tip and optional unequal share weighting. Keep units, rates, and time periods consistent so the result reflects the scenario you intended to model.
Example and practical context
Use your current bill split numbers as the baseline, record the result, then change one meaningful assumption and recalculate. For example, changing a price, rate, measurement, quantity, timeline, or cost while keeping the other inputs fixed shows how sensitive the outcome is to that one variable.
