Budget calculators
The calculations people actually need when planning a month. Each one runs in the browser, nothing is sent to a server and no sign-up is needed. Every reference figure comes from an official source, and each calculator says which one.
Budget calculator
Income against spending by category: what is left at the end of the month, your savings rate and which categories take the largest share.
The biggest line in most budgets is housing, and this shows it plainly
Emergency fund calculator
How much to set aside to cover three, six or twelve months without income, how much is left to save and how long it takes at your monthly amount.
Anchored on unemployment duration published by the Bureau of Labor Statistics
How much to save each month
Works backwards from a goal and a date to the monthly amount, and shows what that means for a single paycheck when you are paid every two weeks.
Reference point: what an average US household has left after spending
How much rent can I afford
The 30 percent threshold in dollars, a stricter 25 percent line, and what is actually left after rent, utilities and debt payments.
Based on the cost burden definition used by the Department of Housing and Urban Development

A calculation shows the target, tracking shows the way
A calculator answers the question “how much”, but the plan is funded from real money that leaks into everyday spending. Budget OK shows where it goes: an entry takes a couple of seconds and the category limits are visible as you spend.
