I'm self-employed and my monthly income fluctuates pretty wildly depending on projects. Some months I make way more than others, which makes it really hard to plan bills and expenses. What's the best approach to budgeting with irregular income like this?
Most self-employed people handle this by calculating your average monthly income over the last year or so, then budgeting based on that lower number - it's conservative but keeps you from overspending when money's tight. Set aside a portion of your bigger months into a separate account (like 20-30% or whatever feels right) so you've got a buffer for the lean months, and treat it like your safety net rather than extra spending money. Bills get paid from your baseline budget, and anything above that goes to the buffer or savings until you've got a few months' worth stashed away. Once you've got that cushion built up, the unpredictability stops feeling so stressful because you're not living paycheck to paycheck.
The tricky part is whether you want to smooth out the ups and downs or just survive the lean months - because they're pretty different strategies. Using your average is solid, but the real pitfall people miss is not keeping a separate buffer account for taxes. When income swings wildly, it's super easy to spend that extra money from a good month and then realize come tax time you owe a chunk you didn't set aside. I'd suggest separating your money into three buckets: one for regular bills based on your conservative average, one specifically for taxes (usually around 25 - 30% of income depending on your situation), and then a true buffer fund that absorbs the month-to-month swings. That way a slow month doesn't panic you, and a great month doesn't trick you into lifestyle creep that leaves you short later.
