Want to see what you can afford this pay period?
Calculate your income first, then choose a number to open or copy.
What this tells you
Your average shows the middle of your recent income. The safer planning number uses the lowest two entries when you provide at least three, helping you avoid building a plan around an unusually high period.
Simple example
For six biweekly incomes of $900, $1,200, $800, $1,000, $1,100, and $700, the average is $950. The lowest two average $750, so $750 is the safer per-period planning number.
How to use this result
Use the safer number for bills and essentials when income changes often. Treat income above that amount as room for savings, a buffer, irregular expenses, or flexible spending.

FAQ
Which income should I enter?
Enter recent take-home income from equal-length pay periods. Include tips, commissions, gig or freelance pay, seasonal work, bonuses, or changing hours when they are part of what you received.
Why use the lowest two periods?
Their average creates a cautious starting point without relying only on one unusually low or high period.
What if I have only one or two entries?
The calculator uses the lowest entered amount as the conservative planning number.
Is this the same as planning one paycheck?
No. This calculator estimates an income number to plan around. Use the Paycheck Budget Calculator to allocate one actual paycheck.
