Frequently asked questions
Can I split a bill unevenly?
Yes — most split tools let you weight by person, so couples or groups with different shares settle correctly.
How is cost of living compared?
Category by category — housing, food, transport — using index values you can adjust to your own spending profile.
Do the event budgets include contingencies?
A buffer percentage is built in as an adjustable input, because real weddings and parties always exceed the first draft.
