Work & money / Free decision worksheet

Can a small business fit your life after forty?

Start with one useful offer, one real customer problem, and the hours you actually have. Work out the numbers before buying a course, building a website, or paying for ads.

For a first service, side project, or small product offer. This worksheet models one offer and one month. It cannot predict demand or promise income.

Write an offer someone can say yes to

Use a skill you can demonstrate. Name a specific customer, a specific result, and a clear boundary. A narrow paid test teaches more than a long list of services.

"I organize one room of paper files for local self-employed people. In a two-hour session, we create labeled categories and a next-action list. I do not provide bookkeeping or tax advice."

Other starting points might be a garden maintenance visit, a beginner spreadsheet lesson, or editing an existing professional biography. These are examples, not verified opportunities. Check any training, licensing, insurance, accessibility, or local requirements that apply before offering the service.

  • Customer: Who has the problem and can authorize paying?
  • Deliverable: What will they receive, by when, with how many revisions?
  • Boundary: What is excluded, and what happens if either side cancels?
  • Evidence: What sample or demonstration can you show honestly?

Check the price, workload, and monthly goal

Use one currency consistently. The $ label is illustrative. Include packaging, shipping you pay, supplies, subcontracting, and expected customer acquisition cost in other cost per sale. Include fixed transaction fees there; enter percentage fees separately. Do not count an expense twice.

Hours per sale should include finding customers, delivery, travel, administration, and revisions. Divide recurring unpaid work across your expected sales and include that time. A zero-hour "passive" offer is not supported: maintenance and customer support still require a realistic estimate.

Calculation inputs stay in this page and are not sent by this tool. They are not saved; reloading clears your changes. The site's general consent-controlled analytics may measure the page visit. No account is needed.

Change the example values and select "Check my business scenario" to calculate your result.

See the formulas and assumptions
  • Contribution per sale = price minus other per-sale cost minus price multiplied by the combined fee and refund percentages.
  • Break-even sales = monthly fixed cost divided by positive contribution, rounded up to whole sales.
  • Sales for goal = (monthly fixed cost + profit goal) divided by positive contribution, rounded up.
  • Monthly capacity = available hours divided by hours per sale, rounded down.
  • Profit at capacity = capacity multiplied by contribution minus fixed cost.

The refund percentage is a simple revenue reserve. Costs are still charged on every sale in this model. It does not model actual returns, recovered inventory, chargebacks, or whether a platform refunds its fees. Use your provider's real terms when budgeting.

Profit here is before income taxes, owner pay, pension contributions, debt principal, and reinvestment. It is not take-home pay. Sales taxes collected for a tax authority should not be treated as your price or revenue here. Startup expenses are excluded unless you put a monthly allocation into fixed costs; cash timing is also excluded.

Read the example without fooling yourself

At $150 per sale, $20 in other costs, a 3% platform fee, and a 5% refund reserve, contribution is $118 per sale. With $100 monthly fixed costs, you need 14 sales for at least $1,500 profit before owner pay and tax. At three hours per sale, that is 42 hours.

A 40-hour month supports only 13 whole sales, producing $1,434 before owner pay and tax under these assumptions. The example misses the target even if every available slot sells. Demand may be lower still. Test a different price or a genuinely smaller scope; do not simply erase the hours or refund allowance to make a result look better.

A first-client experiment you can finish in two weeks

  1. Days 1-2: choose a narrow problem. List three people or businesses you can appropriately ask about it. Ask what they do now, what is difficult, how often it happens, and what they have already paid to solve it. Do not treat politeness as a purchase commitment.
  2. Days 3-4: make one sample. Use your own material or obtain permission. Show the before, the deliverable, and the limits. Do not invent testimonials or previous customers.
  3. Days 5-7: offer one paid pilot. Explain the scope, price, timing, cancellation terms, and how payment will work. Ask permission before sending a proposal. Set a spending limit you can afford to lose; do not borrow to validate an untested idea.
  4. Days 8-12: deliver and record the real effort. Track every working hour, expense, revision, and question. Keep customer information secure. Ask whether the result solved the original problem and what remained frustrating.
  5. Days 13-14: decide using evidence. Recalculate with actual costs and time. Continue if a customer paid, the work was useful, and the return justified the effort. Revise the offer if the scope or price was wrong. Stop or change direction if nobody needed it enough to pay.

One sale is a learning signal, not proof of recurring demand. Before expanding, repeat with unrelated customers and see whether acquisition effort, delivery quality, and margins hold up.

Choose the revenue model you can actually maintain

  • Service: A clear deliverable can be tested quickly, but capacity depends on your time. Price customer acquisition and revisions into the offer.
  • Download: Build something that solves a repeatable problem. Budget updates, support, refunds, and payment delivery. A PDF alone does not create demand.
  • Subscription: Charge only when there is a continuing benefit you can deliver, a clear renewal price, and a workable cancellation process. Decide what happens in a month when you cannot produce new work.
  • Affiliate publication or directory: Help readers compare real options using transparent criteria. Confirm affiliate acceptance and disclose commercial relationships. Visits, outbound clicks, and purchases are different events; none guarantees the next.

Advertising and affiliate income depend on audience demand and third-party terms. A directory needs accurate listings and ongoing corrections. There is no setup that removes the need to maintain trust, quality, and the business.
