Free guide 03 / Protect profit & cash

Know what each sale leaves you.

More sales do not automatically mean more cash. Include the cost of delivery, understand when money arrives, and test the price before offering a discount.

Calculate your break-even point

Model one product or service for one month. Replace the example figures with your own estimates.

Calculated on this device. We do not send these figures to a server when you edit them.

Your working result

Contribution per sale

Break-even sales / month

Operating result / month*

Compare break-even volume with capacity. Forecast the dates receipts become available and payments fall due.

*A planning estimate using your inputs. Acquisition break-even excludes overhead and tax. Operating result excludes tax, financing and any unentered costs. Fractional customers are an expected-value calculation.

STEP 1

Separate direct cost from fixed overhead

Direct costs rise when you deliver another sale: materials, delivery labor, packaging and transaction fees, where applicable. Fixed monthly overhead is separate. Count each cost once. If the owner does delivery work, include a realistic labor allowance instead of treating that time as free.

  1. List what one additional sale requires.
  2. Add recurring overhead such as rent and essential subscriptions.
  3. Use the same period and currency throughout your model.

Offer | Selling price | Materials | Delivery labor | Fees | Shipping | Other direct cost | Contribution per sale

STEP 2

Find the sales volume that covers the model

For a single offer, break-even units equal fixed costs divided by price minus variable cost. Round units up. If contribution is zero or negative, more of the same sales will not cover fixed overhead. The calculator is a simplified planning model, before taxes, financing and costs you have not entered.

  1. Check that selling price exceeds the direct cost of one sale.
  2. Compare break-even units with your actual delivery capacity.
  3. Test a lower sales volume and a higher cost scenario.

Working template

Monthly fixed cost ÷ (price per sale − variable cost per sale) = break-even sales units

STEP 3

Test discounts against contribution

A discount comes out of contribution, not just headline revenue. If a $100 service costs $60 to deliver, its contribution is $40. A $10 discount reduces that to $30, so four discounted sales contribute the same $120 as three full-price sales, before overhead.

  1. Recalculate contribution at the promotional price.
  2. Include any additional advertising or fulfillment cost.
  3. Set a finish date and compare collected contribution, not just order count.

STEP 4

Build a weekly cash view

Profit and cash arrive on different schedules. Put expected customer receipts on the date funds should be available, not the invoice date. Track supplier payments and payroll on their due dates. An unconfirmed tax refund or provider payout should not be treated as cash already received.

  1. Start with the available cash balance.
  2. Add confirmed expected receipts and subtract planned payments by week.
  3. Flag a low-balance week early and review timing, scope or spending options.

STEP 5

Budget for the full cost of software and labor

Compare setup, recurring subscriptions, usage charges and support costs. Usage-based services can change with volume and retries. Employment-platform costs and statutory obligations depend on the arrangement and location; obtain current details from the provider and qualified adviser where needed.

  1. Record the source and date of each quote.
  2. Estimate normal use and a higher-use scenario.
  3. Assign a spending owner and a review date before expanding usage.

Item | Setup | Monthly base | Usage assumption | Variable charge | Total monthly estimate | Quote date | Review owner

STEP 6

Review one decision each month

Compare the plan with actual collected revenue, actual costs and closing cash. When a forecast is wrong, update the assumption. Choose one concrete decision: adjust scope, change price, reduce a cost or improve the payment process.

  1. Reconcile receipts and expense evidence.
  2. Identify the assumption with the largest effect on cash or contribution.
  3. Document the decision, owner and date to check the result.

Questions before you begin

Is contribution margin the same as net profit?

No. Contribution is sales less direct variable cost. Fixed costs and other expenses still need to be covered. This calculator shows a simplified operating result using the costs you enter.

Can the calculator tell me tax owed or a provider's current fees?

No. Use current official information for tax, provider fees and account limits. This tool helps organize assumptions and run a business-planning calculation.

Must I buy the $100 annual plan?

No. The calculators and guides are free. You may purchase an individual BIZORYN service at its displayed price, or choose the optional $100 annual plan for available tools.

Keep the tools. Put them to work.
