How the fee is set. The monthly fee is these hours at the hourly rate stated in your written proposal, excluding VAT (currently 25.5%). No euro price is shown here until a rate is published, so nothing on this page can be read as an offer.

Only the document and employee counts are copied into the form, where you can change them. Nothing is sent until you submit it.

A planning model, not an offer and not tax advice. It does not calculate tax you owe, it does not estimate or promise any saving, and its output is confirmed only by a written proposal from Classic Garage Oy.

§ 02Read this first

What the engine does, and what it deliberately does not

It does

  • Convert your monthly documents, employees, VAT period, EU trade and advisory hours into minutes of work, using the published values shown under "How this estimate is calculated".
  • Show the result as a range, because real workload depends on the condition of the records.
  • Apply the Finnish VAT-period turnover thresholds to the turnover you enter.
  • Recompute the annual statutory dates from the month your financial year ends.
  • Illustrate VAT arithmetic at the general rate on figures you choose.

It does not

  • Show a euro price. No hourly rate is published on this site yet, so the fee is stated only in the written proposal.
  • Calculate the tax your company owes, or estimate any saving. No tool and no adviser can promise you will pay less tax.
  • Account for reduced VAT rates, exempt supplies, reverse charge or deduction restrictions.
  • Replace advice on your company. General thresholds change with elections, group structures and non-standard financial years.
  • Send anything anywhere. Figures reach us only if you choose to submit the proposal form.

The VAT rate used for the illustration is 25.5%, the Finnish general rate. Check the rate that applies to your own supplies before relying on any VAT figure.
