What this tells you
Your average shows the arithmetic average of the recent income amounts you entered.
The conservative planning number is an Everyday Life Tools methodology.
When you provide at least three income entries, the calculator averages the two lowest entries. With one or two entries, it uses the lowest amount entered.
That exact formula is not presented as an outside financial rule.
We use it to give you a second, more cautious number to compare with your recent average.
USU Extension separately describes the broader concept of using either lower recent income or average recent income when planning with irregular earnings. [S6]
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 conservative per-period planning number.
How to use this result
Our interpretation
One way to use the result is to compare the average with the conservative planning number before deciding what amount feels realistic for recurring bills or spending commitments.
If the two numbers are close, your recent income may have been relatively steady.
If they are far apart, the difference can help you see how much your recent income has varied.
Income above the amount you choose to plan around could have different purposes depending on your circumstances, such as building a buffer, preparing for irregular expenses, saving, or covering flexible spending.
The calculator does not decide which number you must use.

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?
That is an Everyday Life Tools planning choice, not a universal financial rule.
When at least three periods are available, averaging the lowest two creates a cautious comparison number without making the entire estimate depend on only one low entry.
USU Extension discusses the broader idea of planning around lower recent income or an average when earnings vary, but the specific lowest-two formula is ours. [S6]
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.
