Autónomo Calculator (Spain)
Estimate your monthly and annual take-home income as a Spanish self-employed worker (autónomo), including cuota de autónomos, IRPF, and a simple IVA quarterly estimate.
How this autónomo calculator for Spain works
If you work as a freelancer in Spain, your real income is not just your invoice total. You also need to account for:
- Cuota de autónomos (social security contribution)
- IRPF (personal income tax)
- IVA (VAT settlement, usually quarterly)
This tool gives a practical snapshot of your expected monthly and annual cash flow. It helps you answer the common question: “How much do I actually keep?”
What you should enter
1) Monthly income (excluding VAT)
Use your average monthly invoicing base. For example, if you invoice €3,000 + VAT, enter 3000.
2) Deductible expenses
Add recurring business expenses: software, coworking, subscriptions, internet, accounting fees, office supplies, business travel, and similar costs that are valid deductions.
3) IRPF effective rate
In Spain, IRPF is progressive and depends on total income and personal circumstances. Many freelancers use an estimate between 12% and 25% to plan cash flow. This calculator uses your selected percentage as a planning assumption.
4) Contribution mode
You can choose:
- Auto estimate: applies a simplified 2025 bracket-based cuota approximation according to your estimated monthly net performance.
- Manual cuota: useful if you already know your selected contribution base or exact monthly amount.
5) Tarifa plana months
If you are eligible for the reduced flat fee, enter how many months (0 to 12) are charged at €80. The calculator blends this with your regular cuota for the rest of the year.
Quick interpretation of the results
- Net before social security: income minus deductible expenses.
- Annual social security: cuota de autónomos over 12 months (with tarifa plana if used).
- Taxable base estimate: net after expenses and social security.
- Estimated IRPF: taxable base multiplied by your IRPF rate input.
- Estimated take-home: what remains after expenses, social security, and IRPF.
- Quarterly VAT: VAT charged on sales minus VAT paid on purchases, multiplied by 3.
Example scenarios
| Profile | Monthly Revenue | Monthly Expenses | IRPF | Typical Outcome |
|---|---|---|---|---|
| New freelancer (tarifa plana) | €2,000 | €400 | 15% | Higher short-term take-home due to reduced social fee. |
| Growing consultant | €4,500 | €1,000 | 20% | Solid net income but heavier tax planning needed. |
| Low-margin activity | €1,800 | €1,100 | 12% | Cash flow may become tight after cuota and taxes. |
Practical tips for autónomos in Spain
Keep a tax buffer account
Set aside a fixed percentage of every invoice in a separate bank account to cover IRPF and IVA. This avoids quarterly surprises.
Track expenses monthly, not yearly
Waiting until the quarter ends can cause mistakes and missed deductions. Use a monthly routine to keep your records clean.
Review your pricing with net income in mind
Many freelancers price services based on gross revenue goals. Instead, reverse-calculate from your desired net take-home amount.
Recalculate when income changes
If your income rises or falls, update your estimates immediately. In Spain, social contributions and tax planning should adapt to your evolving annual projection.
