How I Do My Whole Monthly Budget in Ten Minutes
My plain way to budget a whole month in ten minutes. The five boxes I use, the sums I run and the free tools that do the math for me.
Why ten minutes is all it needs
I used to think a budget meant a big sheet with forty rows and a whole Sunday gone. I tried that. I quit it three times. The sheet was so full that I did not want to look at it, and a budget you do not look at is just a page.
Now I do the whole thing in ten minutes at the start of each month. Same five boxes, same three sums. It is not perfect. It does not need to be. It just needs to be true and short enough that I keep doing it. That is the whole trick.
If you have never budgeted before, this way is a good start. If you have a big sheet that you hate, this can replace it. You can always add more later, but I find most folk never need to.
The five boxes I use
Box one is rent and bills. Rent, power, water, net, phone and any plan I pay each month. These are the same almost every month so I just copy last months numbers. Two minutes.
Box two is food. I keep it in one line, home food and takeout together. Some folks split them. I did too, until I saw that splitting made me feel bad about the takeout and I stopped looking at the sheet at all. One line is kinder and it still shows the truth.
Box three is getting around. Fuel or bus fare, plus car costs if I have them. Box four is fun, which for me is games, trips with pals and the odd buy I did not plan. Box five is a bit odd. I call it life stuff. Hair cuts, gifts, a new charger when the old one dies. Money that shows up with no warning but shows up every month if I am honest.
The three sums that matter
Sum one is pay minus boxes. If my pay for the month is bigger than the five boxes, the rest is free cash. That number is the whole point of the budget. It is what I can save or spend with a calm mind.
Sum two is the free cash split. My rule is half to savings, half to spend. When the free cash is small, I still split it, even if it is ten bucks. The habit matters more than the size at the start.
Sum three is the scary one but do it any way. Free cash per week. If it is forty, then my fun spend is about ten a day. That tiny number keeps me real at the shop better than any big rule I ever wrote.
How I keep it going
I do the budget on the first day of the month, with coffee, in one sitting. If I skip it once it gets easy to skip twice, so I guard that ten minutes like a meeting with some one I like.
I also check it mid month, but only for three minutes. I look at the food line and the fun line. If they are on track I shut the note and get on with my life. No guilt over small slips. The budget serves me, not the other way.
The tools I use to go faster
I built my own monthly budget tool for this, since I got tired of sheets. You type your pay, fill the five boxes and it shows what is left and what each box eats as a percent. The savings goal tool then tells me how many months to my target.
If you want a plan to aim at, my post on the 50 30 20 rule shows the split I used when I had no idea where to start. And if your budget says there is no free cash at all, that is not a fail. That is just month one of the true picture, and knowing it is worth a lot.
