A free irregular income budget calculator — plan when your income changes
Irregular Income Budget Calculator
Irregular income — commissions, tips, gig work, seasonal pay, occasional bonuses — makes traditional monthly budgeting hard, because no two months look the same. An irregular income budget calculator normalizes those variable amounts into a steady, comparable picture so you can plan with confidence even when your income bounces around.

01— The problem
Why irregular income breaks monthly budgeting
Monthly budgeting assumes your income arrives in a predictable monthly amount. Irregular income does not. A commission might land in one month and not the next. A gig paycheck might come weekly for a stretch, then stop. A bonus might arrive once a quarter, or once a year. If you budget each month as though it were average, a low-income month can leave you short before the bills are paid.
The fix is to stop budgeting one month at a time. Instead, total your variable income over a longer period, convert it to a steady equivalent, and plan your fixed expenses against that smoothed figure. Then the good months build a buffer that carries the lean ones.
Income that fluctuates
Commissions, tips, overtime, seasonal work — amounts that rise and fall month to month.
Income at odd intervals
Occasional bonuses, irregular client payments, one-off projects with no set schedule.
A buffer for lean months
Save the surplus from high months so the low months are covered before they arrive.
02— The method
Normalizing variable income with different and custom frequencies
Clear Budget lets you enter each piece of irregular income with the frequency it actually arrives on — including a custom frequency where you set how many times it happens per year. Every line is then converted to a common yearly basis and shown as daily, weekly, monthly and annual equivalents, so bumpy income becomes a steady, comparable number you can plan against.
Occasional bonus
Enter a $3,000 annual bonus once and it spreads to about $250 a month — counted, but not double.
Irregular client pay
Use a custom frequency (e.g. 8 times a year) to model payments that have no fixed schedule.
Seasonal work
Enter peak-season income as a limited-run amount and see its smoothed monthly equivalent.
Steady base pay
Combine a regular part-time wage with the variable amounts above in one combined total.
Plan on the average, not the peak
Base your fixed expenses on the smoothed average, not your best month. That way a strong month creates a surplus you can bank, while a weak month still has enough to cover the bills. Future irregular income is never guaranteed — plan conservatively and treat anything above the average as savings, not spending money.
03— A simple example
An irregular income example
Say you have a steady part-time wage of $1,200 a month, irregular freelance pay of about $600 roughly every six weeks, and a $2,400 annual bonus. Here is how those combine into one smoothed monthly figure.
Steady wage
$1,200
per month
Freelance (avg)
~$433
$600 / 6 weeks
Bonus (avg)
$200
$2,400 / year
Smoothed income
~$1,833
