    What this means for you

    • ·At a typical bank financing cost of around 5% per year, this working capital silently costs you €7,890.41 in interest each year.
    • ·Getting your customers to pay 10 days earlier would free €39,452.05 in cash, permanently.
    • ·Negotiating longer payment terms with one or two key suppliers can free as much cash, without selling more.

    Reference rate: ~5% per year (2024), based on the ECB's published interest rate on new bank loans to euro-area small and mid-sized companies (loans up to €1M). Your actual cost of financing may differ materially depending on your bank, sector and credit profile.
