The number of over-indebtedness files submitted to the Banque de France increased by 9.8% between 2024 and 2025, and the trend is accelerating with an increase of about 11% in the first seven months of 2026. This deterioration comes after a decade of almost continuous decline. It signals that traditional budget management methods are no longer sufficient in the face of declining purchasing power. We will examine the technical levers that can truly optimize a budget on a daily basis.
Household Savings Rate and What It Masks About Budget Management
The savings rate of French households remains structurally high compared to the European average. This aggregated figure hides a polarized reality: a fraction of households saves massively, while another fails to build any safety net.
The monthly financial inclusion barometer published by the Banque de France in August 2026 confirms this divide. The submission of over-indebtedness files increased by 12.1% in August 2026 compared to August 2025. This is not a weak signal; it is a structural alert.
We observe that guides that simply recommend “saving 20% of one’s income” ignore this reality. For a household whose fixed expenses consume nearly all of its salary, the main lever is not savings but the restructuring of fixed charges. Consulting the site credit-infos.fr for finance helps identify the credit items that weigh most heavily on a budget and compare restructuring options.
Restructuring Fixed Expenses: Insurance, Energy, and Recurring Subscriptions
Fixed charges represent the primary lever for budget optimization. Unlike variable expenses (food, leisure), they can be renegotiated periodically but yield recurring savings over twelve months.
Insurance and Protection
The law allows for the cancellation of a home or auto insurance contract at any time after the first year. We recommend comparing coverage line by line, not just the monthly premium. A cheaper contract with a doubled deductible often costs more in the event of a claim.
- Check the amount of the deductible per claim, not just the annual premium
- Control the compensation limits, especially on furniture and electronic devices
- Remove redundant coverage with the bank card (travel insurance, vehicle assistance)
Energy and Telecom Contracts
Fixed-price energy offers protect against price increases but lock the consumer in. Comparing the price of kWh including tax over the actual commitment period remains the only reliable method. Online simulators rarely aggregate local taxes, which skews the comparison.
For telecom plans, the proliferation of integrated streaming subscriptions inflates the bill without the consumer realizing the cumulative impact. A quarterly audit of all automatic withdrawals is sufficient to identify dormant items.
Income Distribution Method: Beyond the 50/30/20 Rule
The 50/30/20 rule (needs, wants, savings) has become a standard widely adopted. It has the merit of simplicity. It also has a major flaw: it does not distinguish between compressible variable expenses and incompressible variable expenses.
The food item, classified under “needs” at 50%, actually contains significant optimization potential. Planning meals for a week and establishing a strict shopping list reduces food waste and impulsive purchases. This is not common sense advice; it is a method whose effect can be measured as early as the second month.
Adapting the Method to Irregular Income
Self-employed workers or employees with a significant variable component cannot apply a fixed ratio to fluctuating income. We recommend a two-step approach:
- Calculate the average net income over the last six months to set a base budget
- Allocate any surplus above this average to a separate savings account distinct from the checking account
- Only draw from this buffer when the monthly income falls below the average, not for discretionary spending
This approach transforms the irregularity of income into an automatic savings mechanism, without monthly willpower effort.
Account Tracking Tools: Banking App or Dedicated Spreadsheet
Budget management apps are multiplying, but not all are equal on a specific technical point: automatic categorization of expenses. Most use transaction labels provided by the bank, which are often cryptic or poorly standardized.
A homemade spreadsheet (or a tool like Google Sheets with conditional formulas) offers complete control over categories. The initialization time is longer, but the reliability of tracking is superior. For effective tracking, we recommend limiting categories to a maximum of eight: housing, food, transportation, insurance, health, leisure, savings, miscellaneous.
Multiplying subcategories creates a cognitive load that leads to abandoning tracking after a few weeks. A simple tracking system maintained over time outperforms a sophisticated system abandoned in March.
Progressive Investment and Emergency Savings
Before thinking about investment, the priority remains building an emergency savings equivalent to a few months of fixed expenses. Without this safety net, the slightest unforeseen event (breakdown, job loss, health issue) pushes towards consumer credit, whose cost negates the gains from rigorous budget management.
Once this savings is established, progressive investment (regular contributions rather than a single placement) smooths the entry risk into the markets. Automating a monthly transfer to an investment vehicle removes the decision-making bias that leads to waiting for the “right moment,” which never presents itself clearly.
Managing personal finances is not a theoretical exercise. The marked increase in over-indebtedness in 2025 and 2026 shows that the leeway is shrinking for a growing share of households. Restructuring fixed charges, adapting the distribution method to the reality of one’s income, and maintaining a sober yet regular tracking of accounts: these three axes produce measurable results as early as the following quarter.
