Extract: Government spending has increased substantially in recent years. Consequently, the breakeven oil price rose to $106 a barrel in 2014 from $69 a barrel in 2010. As a result, with the large decline in oil prices, the fiscal deficit has increased sharply and is likely to remain high over the medium-term.
Suppose a company sells its product for $20 per unit, and the variable cost per unit is $5. This results in a contribution margin per unit of $15. If fixed costs are $3,000, the breakeven point is $3,000/$15=200 units. This breakeven point could also be expressed as the total revenue of 200*$20=$4,000.he total cost at a volume of 50 units is $215. The variable cost at 50 units would be 50*3.9=$195. The fixed cost would be the difference between $195 and $215=$20. You could arrive at the same figure by using the total cost at 10 units ($59).
