Open your category breakdown for the month and you will usually find that two or three categories account for the lion's share — say groceries, rent, and eating out making up 70% of everything. This is called concentration, and on its own it is neither good nor bad. What matters is which categories are concentrated and whether you chose it.
Healthy concentration
If your biggest categories are the essential, low-flexibility ones — rent, groceries, utilities — concentration is just what a normal budget looks like. You cannot do much about rent, and you should not try to starve groceries. A life where the necessities dominate is a stable one.
Concentration worth a look
It is a different story when a large, flexible category sits near the top. If eating out and delivery together rival your grocery bill, that concentration is a lever — a place where a modest change frees real money, because the category responds to your choices. The 20% you might trim from a ₴8,000 dining habit is worth far more attention than the 20% you will never trim from rent.
Why this is good news
Concentration makes optimisation simple. You do not have to track 25 categories like a hawk — you focus on the two or three that move the total, and ignore the long tail of small ones. Fixing your top flexible category does more than nickel-and-diming everything else combined.
- Look at your top three categories and split them into fixed (rent, utilities) and flexible (dining, delivery, taxi).
- Put your effort — and a budget — on the largest flexible one.
- Leave the small categories alone; they are not where the money is.
