Type in what's in your account, when you're next paid, and what's coming out before then. You'll see, day by day, whether the money lasts and what's left for you.
Bills, subscriptions, pay-later installments, anything with a date. Anything dated on payday counts, since it can clear before your pay lands.
Until Payday is the full version: bills that repeat, pay-later plans, big bills split across paychecks, and a check-in each payday. It's free.
The calculator starts from your balance today and takes each payment off on the day it's due, in date order. Three things come out of that:
Many banks take the morning's debits before a deposit posts. Counting payday payments as "before" keeps you on the safe side.
Add each installment as its own payment with its own date. Plans from different providers all come out of the same account, so seeing them on one list is the point.
Only in your own browser, so the numbers are still here if you come back. Nothing is sent to a server from this page.
This is a planning tool, not financial advice. It only knows the numbers you give it, so check your real balance before you spend.
