This will sound crazy, but we have never really had a budget - all the years we have been married. I was retired for 4 years before we even did a spending "audit" (write down and add up every expenditure for a year.) Neither of us is especially into "toys". We like to spend on the same things at the same time (travel and eating out, for instance.) We are naturally frugal, but are willing to splurge at times. Full disclosure - due to working past FI as explained in other posts, our income flow and stash has made it perhaps easier to skip budgeting than for some of the folks on the forum ("No brag, just fact." from Guns of Will Sonnett.) Having said that, we never budgeted during the accumulation phase either. We "saved first" and spent the rest - I guess that was our budgeting method.
The only thing I watch carefully is our cash draw (from investments) at the first of the year - and if we are "forced" to draw more later in the year. We are able to "titrate" our total expenses within a year by seeing how much is left toward the end of the year. If there is much left over, we can give more to charity or buy a big ticket item or travel. It's about that basic and seems to work so far.
The biggest single factor making this all work is our similar outlook on money, "things", experiences, charity and commitment to each other. If this sounds "pie in the sky", I make no apologies (see quote from Will Sonnett above.)
I don't recommend this approach, I just throw it out to suggest not EVERYONE has to budget to control spending or even to plan. More than most situations, YMMV.
