Computer Program for Cost Estimation of Agricultural Machines

Abstract

A user-friendly computer program is developed in Visual Basic environment to determine the all types of machinery costs on hour and hectare basis. The program is also capable to compute breakeven area and time of use of machines to get back return on investment. The input parameters of the developed program are mainly initial price, life of machine, rate of interest, fuel cost, labor wages etc. for power source as well as implement. The total cost is being calculated in two heads namely fixed and variable cost. The fixed cost consists of depreciation, interest, taxes, housing and insurance cost, while variable costs includes fuel, lubrication, wages, repair and maintenance cost. The developed program successfully calculates the cost of operation in rupees per hour and in rupees per hectare of different combinations of power sources and implements. The breakeven analysis of any combination of the power source and implement can also be analyzed. This program can be a useful tool for suggesting the farmers in purchasing a machine as well as in deciding the custom hiring rates etc. This can also help to entrepreneurs who are engaged in custom hiring services to decide the hiring rate of different machinery on the basis of breakeven analysis.

Kompjuterski program prilagođen korisniku je razvijen u Visual Basic okruženju da odredi sve tipove troškova mašina po času i hektaru. Program takođe omogućuje izračunavanje oblasti izjednačenja i vreme upotrebe mašina do povraćaja investicije. Ulazni parametric razvijenog programa su uglavnom početna cena, radni vek mašine, kamatna stopa, troškovi goriva, troškovi rada itd, za pogonske mašine i priključke. Ukupni troškovi se izračunavaju u dve grupe, fiksni i varijabilni troškovi. Fiksni troškovi se sastoje od depresijacije, kamate, poreza, smeštaja i osiguranja, dok varijabilni troškovi uključuju gorivo, mazivo, plate, popravke i održavanje. Razvijeni program uspešno izračunava troškove rada po času rada i po hektaru, za agregate različitih pogonskih i priključnih mašina. Analiza bilansa svakog agregata takođe može da se izvede. Ovaj program može da bude korisno sredstvo za preporuke farmerima pri kupovini mašina, pri određivanju cene iznajmljivanja i sl. Ovo takođe može da pomogne preduzimačima u servisima da odrede cene iznajmljivanja različitih mašina na osnovu analize bilansa.
