MISSION 06 / Enterprise

Make the numbers work

A useful idea still needs a realistic plan for paying for materials, work and maintenance.

Your challenge

Build a simple financial model for your project. Compare prices and costs, calculate break-even and test what happens when one assumption changes.

LEARN & APPLY / 1

Separate the costs

Variable costs change with each item or service delivered. Fixed costs do not change directly with each unit in the model’s range. Label estimates and record the date of any quote.

Try it yourself

List fixed and variable costs for your offer.

LEARN & APPLY / 2

Calculate contribution

Contribution per unit equals selling price minus variable cost. For a fictional item priced at KES 250 with KES 150 variable cost, contribution is KES 100. KES 3,000 fixed costs require 30 units to break even.

Try it yourself

Calculate contribution and break-even for your own assumptions.

LEARN & APPLY / 3

Check cash and uncertainty

Cash may leave before revenue arrives. A profitable-looking plan can still run out of cash. Test lower sales, higher costs and a different price before making a commitment.

Try it yourself

Create three scenarios and recommend proceed, revise or stop.

WHAT YOU WILL BE ABLE TO DO
  • Calculate contribution and whole-unit break-even, including transaction costs.
  • Explain cash timing and identify a financial scam warning sign.
WORKED EXAMPLE

See the thinking.

KES 250 price minus KES 150 unit cost gives KES 100 contribution. KES 3,000 fixed costs require 30 units. Add KES 20 delivery/transaction cost: contribution becomes KES 80 and break-even is 37.5, rounded up to 38 whole units. Sales are not the same as cash received.

RETRIEVE. EXPLAIN. CHECK.

What happens if variable cost equals or exceeds the selling price?

Write your own answer before opening the explanation. Then improve one sentence using what you learned.

Compare your reasoning

There is no positive unit contribution to cover fixed costs in this model. Selling more does not fix it. Revise price, costs or the offer, and examine cash timing before any commitment.

Stretch yourself

Build a fictional weekly cash table. Identify urgency, advance fees and requests for a PIN in a fictional offer. No real purchases, borrowing or transfers are required.

TEN-MINUTE FIRST TRY

Try before you read the solution.

The Strategist prices a fictional kit at KES 300, with KES 180 variable cost and KES 2,500 fixed costs. How many whole kits break even?

Short lessons for this project

One project, growing across missions

Choose a fictional club service, a water-data investigation, or an accessible information tool as your capstone. Keep the same problem brief through your budget, prototype, tests, revision and final defence. The crew exercises teach a method; apply that method to your chosen project and explain any adaptation. Simulation is a complete route.

THE CREW AT WORK / GUIDED PRACTICAL

Can the club cover its costs?

Strategist

“Thirty sales at KES 250 should cover our KES 3,000 setup.”

Builder

“Materials cost KES 150 and delivery KES 20 per unit. Let’s include both.”

01 / PREDICT

Does revenue tell you whether the project makes a surplus?

Write a prediction before you reveal the worked reasoning.

Your starter material

Fictional prices: selling price KES 250/unit, materials KES 150/unit, delivery KES 20/unit, fixed cost KES 3,000. Compare 30 and 38 sales. Assume all units made are sold for this first model.

PRACTICAL STEP 1

Classify costs

List fixed and per-unit costs, then compute contribution per unit = price − materials − delivery. Keep units and assumptions visible.

PRACTICAL STEP 2

Test the volume

Use the budget lab. Calculate revenue, total cost and surplus for 30 and 38 units. Find the first whole-unit break-even volume; test the unit just below it.

PRACTICAL STEP 3

Check cash timing

Create a two-row timeline: costs paid before sales, then cash received. Explain how a project can eventually break even but still need cash upfront. Add one plausible cost you initially missed.

INTERACTIVE / NO ACCOUNT OR AI KEY NEEDED

Cost calculator

Predict a result first. Change an input, compare the output and explain why it changed. These fictional models are learning aids.

Contribution/unit: KES 80.00
Revenue: KES 7500.00
Total cost: KES 8100.00
Surplus / loss: KES -600.00
Break-even: 38 units (check contribution and assumptions)

Tool inputs reset when you leave. Download results or record them in your private mission workbook.

Compare with the crew’s reasoning

Contribution is KES 80. At 30 sales the result is 30×80−3,000=−KES 600. At 38 it is KES 40. Break-even is ceiling(3,000/80)=38 units. If contribution is zero or negative and fixed costs are positive, selling more cannot cover those costs under this model.

Finding the answer is not evidence of mastery. Explain it, test a changed input and record your own work.

Your evidence checklist

  • 30 units loses KES 600; 38 yields KES 40.
  • I test a changed price or cost, not just the default.
  • My cash timeline distinguishes payment timing from profit.

Independent challenge

Only 80% of produced units sell. Rebuild the model: production costs apply to all units made, revenue only to those sold.

A DIFFERENT WAY TO TRY IT

Make the idea your own.

Choose a twist. Use paper, a sketch or a conversation.

Optional practice. Copy useful observations into your workbook; choosing a twist does not record completion.

Compare ideas with someone you know. Sharing is optional.
