Breakeven calculations

  • The breakeven point is the level of output at which the total revenue is exactly equal to total costs

    • At the breakeven point, the business is making neither a profit nor a loss

  • Breakeven calculations include the following:

    • Calculating the contribution

    • Calculating the breakeven point

    • Calculating the margin of safety

    • Calculating the profit or loss

    • Calculating the impact on breakeven of a change to costs or revenue

Calculating contribution

  • Contribution per unit is used to calculate the breakeven point

    • It is calculated using the formula

Contribution      =        Selling price  Variable cost of producing one unit

  • It is called contribution, as once the variable cost of the unit has been paid, the remainder of the selling price contributes to paying the fixed costs of the business

Calculating breakeven

  • Breakeven is calculated using the formula

Break Even Point        =          Fixed CostsContribution per unit

Worked Example

Selected cost and revenue data for Cannock Chase Glamping

 

£

Revenue per pod per night

95

Variable costs per pod per night

19

Annual fixed costs

55,000

Using the information in the table, calculate how many pods need to be occupied each month for Cannock Chase Glamping to break even

[4]

Answer:

Step 1: State the formula to calculate the breakeven point

Break Even Point=                 Fixed CostsContribution per unit           (1)

Step 2: Calculate the contribution

Contribution = Selling price  Variable cost per unit  = £95  £19= £76(1)

Step 3: Apply the formula to calculate the breakeven point

= £55,000£76= 723.68   (1)

Step 4: Always round UP to the nearest whole number because only whole products can be sold

723.68 = 724 camping pods      (1)

Calculating the margin of safety

  • The margin of safety is the difference between the actual level of output of a business and its breakeven level of output

  • The margin of safety can be calculated using the following formula

Margin of Safety = Actual output  Break even output

Worked Example

The cost, sales and revenue for an electric bicycle manufacturer are presented in the table below

Annual fixed costs

£42,000

Selling price per unit

£750

Variable cost per unit

£350

Number of units sold

240

Using the data, calculate the margin of safety. You are advised to show your workings 

[3]

Answer:

Step 1: Calculate the contribution

Contribution = Selling price  Variable cost per unit  = £750  £350= £400 (1)

Step 2: Apply the formula to calculate the breakeven point

= £42,000£400 105 units  (1)

Step 3: Apply the formula to calculate the margin of safety

= 240 units  105 units= 135 units   (1)

Calculating profit or loss

  • The total contribution is used to calculate profit or loss

    • Total contribution is calculated using the formula

Total contribution = Revenue  Total variable costs

  • Once the total contribution is calculated, the following formula determines whether a business has made a profit or a loss

Profit (Loss)= Total contribution  Total fixed costs

Worked Example

Treetops is an outdoor activity centre. In 2024, it earned revenue of £462,540, with fixed costs of £281,720 and total variable costs of £131,280

Calculate the total profit made by Treetops in 2024

[3]

Answer:

Step 1: Calculate the total contribution

Total contribution = Revenue  Total variable costs= £462,540  £131,280= £331,260 (1)

Step 2: Use the contribution figure to calculate profit

Profit (Loss) = Total contribution  Total fixed costs= £331,260  £281,720= £49,540 (1)

  • Treetops made a profit of £49,540 in 2024 (1)

The impact of changes in price, output and costs on the breakeven point

  • Changes in the selling price, fixed costs and variable costs have an impact on the breakeven point

A diagram showing factors affecting the breakeven point: lower selling prices and higher fixed and variable costs increase it, while higher prices and lower fixed and variable costs decrease it.

Explanation of the impact of changes

Impact

Why it matters

Rise in variable costs

  • Contribution per unit falls because each unit now costs more to make

  • Breakeven output rises (more units must be sold to cover the same fixed costs)

  • The breakeven revenue line shifts upward on a graph

  • Profit margin per unit narrows

  • Managers may seek to increase prices, improve efficiency or find cheaper suppliers

Fall in variable costs

  • Contribution per unit rises

  • Breakeven output falls (fewer units are needed to cover fixed costs)

  • The breakeven revenue line shifts downward

  • The business reaches profit sooner and has a greater margin of safety before losses begin

Rise in fixed costs

  • The fixed-cost figure increases while the contribution per unit stays the same

  • Breakeven output rises because a larger fixed-cost value must be covered

  • The risk of loss grows if sales volume cannot be expanded

  • Management may cut spending or look to increase the scale of production

Fall in fixed costs

  • The fixed-cost figure decreases

  • Breakeven output falls, and profitability is reached sooner

  • More of each month’s sales revenue becomes profit once the lower fixed-cost value is covered

Rise in selling price

  • Contribution per unit rises as long as the variable cost per unit is unchanged

  • Breakeven output falls because each sale contributes more towards fixed costs

  • Higher prices might reduce demand

  • If the volume of sales drops significantly (price elastic demand), the benefit of higher prices could disappear

Fall in selling price

  • Contribution per unit falls

  • Breakeven output rises as more units need to be sold to cover fixed costs

  • A lower price may boost demand

  • The business must judge whether the extra sales volume really will arrive and cover the larger breakeven quantity

Worked Example

PART 1: An increase in the selling price

Roleplay Rascals is an indoor play centre for preschool children. It currently charges £11 per child per play session. It incurs monthly fixed costs of £8,200, and each play session costs £2.30 on average per child. On average, 1,400 play sessions are sold each month

Calculate the impact on Roleplay Rascals' breakeven point if the selling price per play session is increased by £1

[4]

Answer:

Step 1: Calculate the current breakeven point

BEP = Fixed costsContribution= £8,200£11  £2.30= £8,200£8.70= 943 play sessions (1)

Step 2: Calculate the new breakeven point

= £8,200£12  £2.30= £8,200£9.70= 846 play sessions (1)

Step 3: Calculate the change

= 943 play sessions  846 play sessions= 97 play sessions (1)

  • The breakeven point falls by 97 units (1)

Worked Example

PART 2: An increase in staffing costs

Following the price increase, fixed costs rise to £9,600 when a new staff member is appointed

Calculate the impact on Roleplay Rascals' breakeven point given this increase in staffing costs

[3]

Answer:

Step 1: Calculate the new breakeven point

BEP = Fixed costsContribution= £9,600£12  £2.30= £9,600£9.70= 990 play sessions (1)

Step 2: Calculate the change

= 990 play sessions  846 play sessions= 144 play sessions (1)

  • The breakeven point rises by 144 units (1)

Worked Example

PART 3: A decrease in variable costs

Roleplay Rascals' manager shops around for a better deal on drawing and painting supplies. This reduces the variable costs by 20%

Calculate the impact on Roleplay Rascals' breakeven point given this reduction in variable costs

[4]

Answer:

Step 1: Calculate the new variable cost per unit

= £2.30 × 0.2= £0.46= £2.30 = £0.46= £1.84 (1)

Step 2: Calculate the new breakeven point

BEP = Fixed costsContribution= £9,600£12  £1.84= £9,600£10.16= 945 play sessions (1)

Step 3: Calculate the change

= 990 play sessions  945 play sessions= 45 play sessions (1)

  • The breakeven point falls by 45 units (1)
