Good morning. まさきん here.
Here’s the short version: trying to overhaul your fixed costs all at once is a great way to burn out. The trick is to start with the items that don’t hurt, then work your way up. Today I’ll walk through the 3 stages my own household uses.
Why start with fixed costs
When people think about improving their household finances, cutting variable spending is usually what comes to mind first, things like groceries or eating out.
But I’ve come to think that reviewing fixed costs is actually the single best form of “asset management” available. The reason is simple.
Cutting variable spending requires constant, daily attention, which makes it hard to sustain.
Fixed costs, on the other hand, only need one round of paperwork. After that, the savings keep compounding without any extra effort.
As a marketer, I’d frame it this way: cutting variable costs is a manual operation you repeat every time. Reviewing fixed costs is a one-time configuration change that keeps paying off.
Step 1: List everything out
The first step is simply writing down every fixed cost by category, housing, utilities, phone and internet, subscriptions, insurance, car-related costs, anything that comes to mind.
What matters here is not worrying about the amount yet. Just get everything visible first. Even a subscription that’s only a few hundred yen a month can add up to something surprising once you see it listed.
| Category | Things worth checking |
|---|---|
| Communications | Number of phone lines, internet line, cloud storage, etc. |
| Subscriptions | Video/music streaming, fitness apps, password managers, etc. |
| Insurance/pension | Life insurance, fire insurance, private pension premiums, etc. |
| Car-related | Loan, parking fees, insurance, tolls, etc. |
Step 2: Sort by how hard each one is to act on
Once everything is listed, sort each item into one of three difficulty tiers. Here’s how I organize mine:
- A. Can act on immediately (no pain): canceling subscriptions you barely use, or downgrading to a free plan. These take a few minutes and barely affect your quality of life.
- B. Needs some comparison shopping (some effort): switching carriers, reviewing your electricity provider, and similar. Comparing options and applying takes time, but the payoff is usually decent.
- C. Needs a structural rethink (a big decision): changing insurance policies, or reconsidering housing itself. These affect daily life significantly, so they need careful thought.
If you try to tackle everything at once without sorting, it gets exhausting. You end up spending all your energy just comparing options and never actually act on anything.
So I’d recommend starting with the A-tier items. Stacking up small wins tends to work better.
That said, some B-tier items are surprisingly easy to start on. Switching your phone carrier is one of them; sometimes just checking your current plan is enough to get moving.
A good first move is checking your current phone bill with a fee simulator.
If you’re on the fence, it might help to look at the simulator’s result before deciding whether to actually switch.

Step 3: Act on it, and keep a record
Once you’ve sorted everything, start executing the A-tier items. One thing that matters more than people expect here is keeping a record.
It doesn’t need to be elaborate, just a quick note of when, what, and how much you cut. A memo field in a budgeting app, or a single row in a spreadsheet, is plenty.
Having a record means you can look back after six months or a year and actually see, in numbers, that the change you made back then is still adding up. That tends to feed your motivation for the next round too.
In my household, we set aside time to review this once a quarter. Reviewing fixed costs isn’t a one-and-done task.
Rate plans and reward conditions from service providers keep changing over time, so I’ve found it’s worth re-checking everything periodically.
A mindset worth keeping in mind
One thing to watch for when reviewing fixed costs: don’t judge purely by the size of the savings. What happens if you mechanically cut a tool that’s directly tied to your work productivity?
The same goes for services your family actually enjoys. Your quality of life could drop, and the change might not stick.
It’s worth weighing “amount saved” against “impact on daily life” together. Moving at a pace you can sustain seems to be the real key.
Wrap-up
Reviewing fixed costs works well as a 3-stage process: list everything, sort it, then act. Following that order makes it much easier to keep going, and less likely you’ll give up partway through.
For that first step especially, I’d recommend starting with the pain-free items, canceling subscriptions you barely use, for example. Small wins tend to carry momentum into the next step.
Don’t treat it as a one-time fix; building a habit of periodically revisiting the list is worth the effort.
In my own case, the biggest win by far came from communications costs. Switching to Rakuten Mobile made a real difference. If you haven’t looked into it yet, it’s worth considering as your first step.
