Cutting expenses is unsexy. Nobody posts reels about switching their liability insurance. But fixed costs are the only lever that works without sacrifice: once you flip the switch, they keep saving you money every month without you thinking about it again.
The list below is roughly sorted by impact — biggest lever first. Most households that work through just the first five items save €80–150 per month, for three to five hours of one-time effort.
Housing
1. Switch electricity provider
Compare on Verivox or Check24, switch to the cheapest green tariff with a 12-month price guarantee. Savings vs. default supplier typically €200–400 per year.
2. Switch gas provider
Same playbook. Especially worthwhile for long-time customers who never switched — there's almost always a three-digit annual saving on the table.
3. Review your internet plan
After 24 months the base fee jumps with almost every provider. Threaten to cancel, accept the retention offer, or switch. €10–15 per month is realistic.
Mobility
4. Review car insurance annually
The switching deadline in Germany is November 30. Run a comparison — people who haven't done it in five years often pay 30–40% too much.
5. Run the numbers on a public transport pass
If you ride the train or bus twice a week, the Deutschlandticket usually beats individual tickets — and you stop thinking about fare zones.
Subscriptions and contracts
6. Consolidate your streaming stack
Netflix + Disney+ + Amazon + Apple TV + Spotify + Paramount totals around €60/month. Rotate one at a time and cut the ones you barely use. Nobody will notice.
7. Audit the gym membership honestly
If the last three months show fewer than eight visits: cancel. Use the exception clauses (moving, illness, job change).
8. Consolidate insurance
Liability, contents, legal: bundles at one insurer are often cheaper than stand-alone policies. Dental add-ons, travel luggage, phone insurance: usually pointless.
Finances
9. Kill current-account fees
Large traditional banks often charge €5–10/month. Online banks are free (typically with a qualifying salary deposit). €60–120/year, no trade-off.
10. Check credit card annual fees
Any premium card under €100/year only pays off if you genuinely use the benefits. Otherwise cancel and move to a free Visa or Mastercard.
11. Pay off overdrafts — don't tolerate them
Overdraft rates run 9–14%. Every euro you carry for more than a month costs more than any savings rate can earn. Priority one.
Cost of living
12. Ration delivery apps
Convenient but expensive. Set a weekly budget (say €40) and stop ordering once you hit it. Works because the number is visible before you order.
13. Plan your weekly shop
List before the store, not in the store. Spontaneous purchases typically cost 20–30% more. Same effect online: let the cart sit overnight.
Mental levers
14. Cancel all subs on a single day
Month-end is best. Go through your standing orders and axe anything you haven't used in the last 30 days.
15. The 24-hour rule above €50
Nothing impulse-bought. Write the wish down, wait a day, then decide. 60% of wants don't survive the night.
16. An annual review with yourself
Once a year: export 12 months of statements, sort your top 20 expenses. Tag each one keep / cut / kill.
17. A dedicated account for fixed costs
Separate sub-account only for rent, utilities and insurance. Monthly transfer from the main account. As long as the fixed-cost account is in the black, you're fine.
Bottom line
Fixed costs are the one savings lever where discipline doesn't matter. Flip the switch once, and the effect runs on autopilot. Three weekend afternoons are enough for a full pass — and from then on you have €800–1,500 per year extra to play with.
