How to Run a First Cash Check on Your Own Assumptions

What the check covers

Quick Check looks at one product or service with a single revenue stream, at a steady monthly run rate from the first month. All results are before tax and before financing. There is no growth or ramp-up, no depreciation, no equipment replacement and no value at the end of the period. It does not calculate IRR, debt service, loans or tax.

The result is a calculation of your own assumptions. It is not a forecast, a feasibility study or investment advice, and a positive result is not an approval.

Step 1: Describe the project

Give the project a name, choose a currency label (USD, EUR or GBP; no conversion is made) and write the decision you are trying to make. Then name one unit you sell, such as a wash cycle, a haircut or a room night. Every volume figure refers to that unit.

Step 2: Enter the seven numbers

1. Upfront installation and startup cash: equipment, installation, fit-out and the cash needed to open.
2. Expected units sold per month. Before opening, this is your expected paid sales. Capacity and footfall are not paid demand.
3. Selling price per paid unit you expect to charge.
4. Variable cash cost per paid unit. Payment fees belong here.
5. Monthly fixed cash costs, such as rent and staff. Loan payments do not belong here; they are financing.
6. Horizon (whole years, 1 to 10).
7. Annual discount rate (%): the yearly return you require on the money you put in. Zero is allowed.

Step 3: Record where each number comes from

For each of the first five inputs, choose a source type and add a short note and a date. The horizon and the discount rate are your own choices, so they have no source type.

• Quote: a written offer from a supplier or landlord.
• Published source: a price list, tariff or other public figure.
• My estimate: your own figure. If you have no quote yet, enter your best estimate here. Results are then labelled as conditional on your estimates.
• Unknown: use this only if you cannot estimate the figure at all. The value is not used, and results that need it stay closed.

An empty value is not zero. Feasivio does not check any source you record; the source type is a note for you and anyone you share the file with.

Step 4: Read the results

• Contribution per unit: price minus variable cash cost.
• Monthly operating cash, before tax and financing.
• Break-even units per month: the monthly volume at which contribution covers fixed costs.
• Simple payback: investment divided by monthly cash, shown only if it falls within your horizon.
• Net present value and an annual cash flow table, with the investment at year 0.

Three sales scenarios change only the units sold, by default at 0.8, 1 and 1.2 times your figure. They are a simple stress test, not a forecast of likely outcomes.

Step 5: Decide what to verify next

The page lists inputs that are missing, unknown, estimated or lacking source detail, with a suggested action for each. Start with the figures your decision depends on most, and replace estimates with written quotes where you can.

The page also offers a fictional example. Its numbers are invented to show how the tool works; they are not market data and not evidence of demand or sales.
