Why Cost Planning is crucial
Becoming self-employed means taking on responsibility — including financially.
Many self-employed people start with motivation and ideas, but without a clear picture of what expenses lie ahead. Yet that is exactly what matters: knowing your costs lets you plan ahead, build reserves, and work more calmly.
Good cost planning provides clarity and security. It helps you realistically assess how much you need to earn in order to live well and build a stable business — without stress, debt, or unpleasant surprises.
One-time start-up Costs
Before you truly begin, one-time expenses often arise. These so-called start-up costs can vary greatly depending on your profession and legal form. What matters is: plan for them early to avoid bottlenecks later.
Typical items include:
- Registration and government fees — e.g. trade registration (20–60 €), commercial register entry or notary costs (for UG/GmbH about 300–800 €).
- Equipment and technology — computer, smartphone, software, work tools, possibly a camera or other equipment.
- Website & branding — domain, hosting, logo, business cards, or a simple online presence (from 100 € to over 1,000 €).
- Advice & support — e.g. tax consulting, legal advice, or start-up coaching.
💡 Our tip: Create a simple list of "absolutely necessary" and "can wait." This helps you avoid spending too much money in the early phase on things that aren't yet needed.
Ongoing fixed Costs
After founding your business, regularly recurring costs arise — so-called fixed costs. They are independent of how much you earn and must be covered every month. Knowing them helps you calculate better and understand what your minimum hourly rate or required revenue should be.
Typical fixed costs include:
- Health and care insurance: Mandatory for all self-employed people — contributions depending on income and insurance between approx. 200–900 € monthly.
- Retirement provision: Voluntary but important. You can save privately or pay into statutory pension insurance (e.g. as an artist via the KSK).
- Taxes & bookkeeping: Reserves for income and VAT, possibly tax consulting (approx. 50–200 € monthly).
- Insurance: Rarely mandatory, almost always recommended. E.g. professional/business liability insurance, legal protection insurance, cyber insurance — costs vary greatly, initially approx. 30–300 €.
- Workplace costs: Rent, utilities, internet, telephone, software subscriptions, possibly co-working space.
- Marketing & communication: Website, tools, social media, possibly advertising or newsletters.
💡 Our tip: Calculate your monthly fixed costs realistically. This way you'll quickly see how much revenue you need to cover your ongoing expenses — and what you can truly afford.
Variable and optional Costs
In addition to fixed expenses, there are costs that change from month to month or may not occur at all. These variable costs depend heavily on how you work, which projects you take on, and what priorities you set.
Typical examples:
- Travel and transportation costs: Client meetings, trade fairs, or training events.
- Further education & coaching: Courses, workshops, or specialized literature to keep your knowledge current.
- Services: External support, e.g. bookkeeping, design, copywriting, or IT help.
- Software & tools: Premium versions of design or AI tools, project management software, or cloud storage.
- Materials: Paper for photo prints, wood for handcrafted products.
- Marketing & growth: Ads, campaigns, event participation, or PR.
💡 Our tip: Plan these costs intentionally — but stay flexible. Create a monthly budget with a small buffer to respond to phases with more or fewer projects.
Reserves and Liquidity
Self-employment also means: there is no fixed salary payment at the end of the month.
Income fluctuates, invoices are often paid late. All the more important is building reserves and keeping an eye on your liquidity — your ability to pay.
A simple rule of thumb:
→ Plan at least 3–6 months of your living costs and fixed costs as a buffer.
This protects you when projects dry up, larger investments come up, or the tax office demands back payments.
A clear structure for your accounts also helps:
- Personal account: for living expenses.
- Business account: for income and operating costs.
- Reserve account: for taxes, insurance, repairs, holidays, or emergencies.
💡 Our tip: Regularly transfer amounts (as a rough rule of thumb, often 30% of profit) to your reserve account — ideally automatically. This builds security without having to think much about it.
Tax Deductibility and Planning
Also see our guide Deducting Expenses Smartly
Many expenses that seem obvious in everyday life can be tax-deductible as a self-employed person — meaning you can subtract them from your profit. This lowers your tax burden and ensures you keep more in the end.
It's important to understand early on what counts as a business expense and how to collect receipts properly.
Typical deductible costs include:
- Work equipment and technology (computer, printer, software, phone)
- Office or home office costs (proportional for home office)
- Travel and transportation costs (e.g. to client meetings or events)
- Telephone, internet, and communication
- Further education and specialized literature
- Marketing and advertising (website, domain, ads, business cards)
💡 Our tip: Use a simple bookkeeping software or app to digitize receipts directly and categorize your expenses. This saves time and keeps you prepared for your tax return.
Example: monthly Cost Scenario for full-time self-employed
How much money do you really need per month to work and live securely? That depends greatly on your industry, location, and lifestyle. A simple example calculation helps you get a sense of how your fixed and variable costs add up.
Example: Freelance designer (full-time, home office)
| Category | Example cost per month | Explanation |
|---|---|---|
| Health & care insurance | 400 € | statutory, income-dependent |
| Retirement provision / reserves | 200 € | voluntary contributions or ETF savings plan |
| Rent (proportional for home office) | 150 € | approx. 25% of housing costs |
| Software & tools | 60 € | Adobe, cloud, project management |
| Internet & telephone | 40 € | professional use |
| Tax reserves | 300 € | for income and VAT |
| Marketing & website | 50 € | domain, hosting, small ads |
| Further education & networking | 50 € | online courses, events |
| Travel & transportation (average) | 50 € | train, public transport, client meetings |
| Miscellaneous / buffer | 100 € | unforeseen expenses |
Total costs per month: approx. 1,400 – 1,600 €
→ Plus your private living expenses (e.g. rent, food, leisure).
So plan for a total of approximately 2,000 – 2,500 € monthly to work comfortably and securely.
Conclusion: get an Overview, plan calmly, stay flexible
Those who know their costs can make decisions, plan, and act more confidently. A clear overview of one-time, ongoing, and variable expenses helps you stay financially stable and calculate realistically.
Nobody has to plan everything perfectly from the start. What matters is creating transparency step by step: Which costs are fixed, which are flexible, which can wait? This way you avoid stress and gain room for what truly counts: your work and your ideas.
