Business maths are mathematics used by commercial enterprises to record and manage business operations. Commercial organizations use mathematics in accounting, inventory management, marketing, sales forecasting, and financial analysis.”

~ Wikipedia on Business mathematics


Mathematics typically used in commerce includes elementary arithmetic, elementary algebra, statistics and probability. Business management can be made more effective in some cases by use of more advanced mathematics such as calculus, matrix algebra and linear programming. ( Wikipedia )

  • Interest calcualations
    • Simple interest calculation Interest = Principal * Interest rate * Time ( I = P * R * T ) ( w:fi:Korko = Pääoma * Korkoprosentti )
    • w:Compound interest arises when interest is added to the principal, so that, from that moment on, the interest that has been added also earns interest. This addition of interest to the principal is called compounding.

  • w:Compound interest calculation arises when interest is added to the w:principal, so that, from that moment on, the interest that has been added also earns w:interest. This addition of interest to the principal is called compounding. ( Wikipedia )
