More than your net salary — and the gap is wider than most starters expect.
More than your net salary. Between your margin and what stays in your account sit the VAT on your margin, your fixed costs, social contributions of 20.5 % and income tax. Replacing a salary therefore means making not that amount in margin but considerably more — every month, including the months when nothing sells.
The calculator on the knowledge base earnings page turns your current net salary into the margin you have to make each week. That is a more useful figure than turnover: in second-hand trade turnover says little, because the purchase price is inside it.
The figures differ per country. There is a separate page per body of law — Belgium, the Netherlands, France and the UK — each with its own contributions and rates, checked at its own government.
Checked on 1 September 2026 at the Belgian INASTI (social contributions, secondary-occupation threshold and minimum contribution) and the FPS Finance (tax-free allowance and rates). The amounts are index-linked: if something no longer matches, let us know.
This is an explanation, not tax or legal advice. Put your own situation to your accountant.
Yes. For antiques and vintage a secondary occupation is almost always the sensible start, because your money is tied up in pieces rather than sitting in your account. In Belgium, if your net taxable income stays under 1,922.16 euros a year you pay no social contributions as a secondary occupation. As a main occupation you pay a minimum contribution every quarter, even in a quarter without sales.
As many as you sell, if you want to keep your stock at level. Sell twelve pieces a month on average and that is nearly three a week. With unique pieces you do not top up to a number — you buy at a rate, because there is no second example of what just sold.
Vintro Pro keeps, per piece, what you paid, when, and where it came from. Your stock list and your margin VAT build themselves while you work.
