What should you do with your savings in September? 5 steps to get your finances in order

For many people, September is the second January. Routines and schedules return, along with the summer bill: trips, back-to-school expenses, weekend breaks and meals out that have accumulated almost without us noticing. It is normal to reach September feeling that you have lost control slightly.

left in the year, your mind is fresher than it will be in December, and any decision you make now still has time to produce results.

Here are five simple steps, in the right order, to bring your finances up to date. You do not need to complete them all in one afternoon. One a week is a good pace.

1. Take stock: where do you really stand?

AnBefore deciding what to do with your savings, it is worth finding out how much you have and how much you can continue saving. Set aside an hour to answer three questions with the figures in front of you:

• How much did the summer cost? Review your transactions from July and August. Not to punish yourself, but to identify any extraordinary expenses —or credit card balances— that you are carrying into September.
• How much do you have and where is it? Add up the money held in current accounts, interest-bearing accounts, deposits, funds, pension plans and other products. Money is often more scattered —and more idle— than we realise.
• What is your actual monthly saving capacity? Subtract your usual fixed and variable expenses from your income. This figure is the basis for everything that follows.

If you identify high-interest consumer debt, that should be the first destination for your savings. Paying it off is usually the most profitable “investment” available.

2. Review —or rebuild— your emergency fund

Summer is one of the times of year when people are most likely to dip into their financial safety net. If you have used it, September is the time to replenish it before considering anything else.

As a general rule, your emergency fund should cover several months of expenses. The exact amount will depend on your circumstances: the stability of your income, whether your household has one or two sources of income, and whether you have dependants. In this article, we help you calculate it by answering five questions about the size of your emergency fund.

The important thing is for this money to meet two conditions: it should be available within a few days and should not be exposed to market fluctuations. However, that does not mean it has to sit idle in a current account losing purchasing power. The inbestMe Savings Portfolio is designed precisely for this purpose: money market funds whose return is linked to ECB interest rates, with no fixed terms or lock-in periods, access to your money within a few days and tax deferred until you withdraw it.

3. Review your goals… or define the ones you do not yet have

Once you have reviewed your finances and secured your safety net, it is time to ask the key question: what are you saving for?

If you have already defined your goals, September is a good time to review them. Are they still the same? Has the time horizon changed? Is the amount you contribute each month still consistent with what you want to achieve? If you are an inbestMe client, the goal forecaster will show you in a minute whether you are on track or should adjust your contributions.

If your goals are still unclear, you do not need a perfect plan. Simply group them according to their time horizon:

• Short term —less than 2 years—: a trip, a new car or an expense you can already see coming. Security is the priority.
• Medium term —between 2 and 5 years—: a deposit on a property, home improvements or a master’s degree. You can seek a little more return, but you need to keep the date firmly in mind.
• Long term —more than 5-10 years—: retirement, your children’s education or building wealth. This is where equities and compound interest can do their work.

Organising your money by time horizon is the basis of what we call the virtuous quadrant of financial planning: first save, then preserve, then accumulate and, finally, plan for retirement. Each person moves through the quadrant in the order that best suits them, but knowing which box every euro belongs in completely changes how you invest it.

4. Match each goal with the right portfolio

Once you have arranged your goals by time horizon, choosing where to invest becomes much easier. The most common mistake is to do the opposite: choose the product first and then try to justify it.

With inbestMe, you can cover the entire quadrant by opening a separate portfolio for each goal:

• Emergency fund and undefined or very short time horizons: Savings Portfolio —EUR or USD—. Maximum flexibility and minimum variability.
• Clearly defined time horizons of 2 to 4 years: Target Portfolios. These set a target return for a specific maturity date and are ideal when you know exactly when you will need the money.
• Cautious profiles with flexible time horizons: Bond Portfolios —Cautious or Bold—, offering an intermediate step between saving and investing in equities.
• Medium and long term: Indexed Fund or ETF Portfolios, with 10 risk profiles and low-cost global diversification. These are the most popular portfolios at inbestMe.
• Retirement: Pension Plan Portfolios, which are index-based and benefit from the tax advantages available on contributions. It is true that the limits are currently low —€1,500 for individual pension plans—, but this also makes the amount relatively manageable to accumulate. Starting at an early age can help you build up a meaningful supplementary pension for retirement.

If you have been accumulating money in your current account and do not know where to start, our article How to organise your money in 2026 explains this same approach step by step.

There is also an important reminder for September: historically, it has been one of the most volatile months of the year. This should not matter. If every euro is held in the portfolio that matches its time horizon, short-term fluctuations stop being a problem because the money you may need soon is not exposed to them.

5. Automate your finances and do not leave it until December

The final step turns a good September intention into a habit:

• Set up regular contributions to each portfolio, adjusted to the saving capacity you calculated in step 1. Contributing every month instead of waiting for the “perfect moment” reduces the risk of investing at the wrong time and removes the temptation to spend money you have not set aside.
• Bring tax decisions forward. If you have a pension plan, spread your remaining contributions up to the deductible limit between September and December instead of investing everything at once during the final week of the year.
• Set a review date. Once a year is enough. If September has worked well as your starting point, make September your annual review date.

In summary

Getting your finances in order in September is not about making major changes. It is about regaining control through a simple method: understand where you stand, secure your safety net, organise your goals by time horizon, match each one with the appropriate portfolio and automate your contributions.

Investing is not about predicting the future; it is about organising the present properly. September is just as good a time as January to begin, with the added advantage that a third of the year still lies ahead.
