Start with a business decision
Choose the outcome you need to understand
Margin101 organises planners around the commercial decision in front of you—not around isolated formulas.
01
Protect Margin
Move from a supplier-cost shock to a defensible price, realistic sales threshold and cash-impact check.
Typical outputs
- Revised cost exposure
- Defensible target price
- Cash requirement
02
Quote to Cash
Connect a viable service rate to a scoped quote, realised job margin, collection cost and short-term cash forecast.
Typical outputs
- Viable service rate
- Realised job margin
- Short-term cash timing
03
Test order profitability
See what an order keeps after product cost, shipping, returns, fulfilment and acquisition spend.
Typical outputs
- Contribution per order
- Shipping threshold
- Acquisition ceiling
04
Plan capacity and growth
Connect capacity, billable utilisation, product mix and sales thresholds before committing to growth.
Typical outputs
- Capacity gap
- Revenue potential
- Break-even threshold
How Margin101 works
A decision workflow, not a mystery answer
Move from assumptions to a calculation you can inspect, compare and take into the next business conversation.
01
Describe the decision
Enter the costs, constraints and target relevant to your business.
02
Inspect the economics
See the result, formula, calculation breakdown and sensitivity.
03
Compare and act
Save a baseline, compare scenarios or export a record before deciding.

A practical business scenario
From “What should we charge?” to a defensible answer
Example: a United Kingdom product business testing a price before indirect tax. The global planner uses the business inputs supplied and does not assume a local tax rate.

Decision output
Required selling price
£110.00
- Cost recovered

- Equivalent markup

66 ÷ (1 − 0.40) = 110
