The monthly income works like this: it aggregates multiple income streams (salary, freelance, rental, interest) into monthly and annual totals. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
Can I model irregular income?
Enter averages; for lumpy freelance income, use a conservative month (not best month) for planning.
Which income streams can I combine?
Salary, freelance, rental and interest - each entered with its own period, then aggregated into consistent monthly and annual totals.
How are irregular incomes converted?
Enter the real amounts and their periods - a quarterly contract becomes its monthly equivalent, so the totals reflect actual cash-flow timing rather than a flat average guess.
