📈 Business Profit Calculator

How do I add a product? Enter the product’s name, how many units you plan to sell each month, what it costs you to make one unit, and what you plan to charge for it. Optionally, you can add a description or location for better AI insights. Then click "Add Product" and you’ll see it appear in your summary.

How is profit margin calculated? We calculate your Net Profit Margin like this:
(Total Revenue - Total Costs) ÷ Total Revenue × 100
This shows the percentage of your sales that turns into actual profit. For example, if you make £2 profit on every £10 of sales, your margin is 20%.

What is the scenario table? It answers the question: “What happens if I sell more or fewer units?” It displays different sales volume scenarios (like low, medium, high) and shows how your net profit changes in each case.

What does the AI Analysis do? Our AI reviews your prices, costs, and margins to suggest ways to improve profit. It may recommend price changes, highlight low-margin items, or suggest bundling or market-specific ideas.

What’s the 12-Month Profit Projection? We use a method called Monte Carlo simulation to simulate 200+ possible future outcomes based on your current data and a bit of randomness. It shows what your profit might look like over the next year in base, best, and worst-case paths.

What’s the Breakeven section for? It calculates how many units you need to sell each month to cover all your fixed and variable costs (aka “breaking even”). It also breaks that number down across all your products to show how each contributes.

What’s the What-If Explorer? This is an interactive area where you can simulate changes — like raising prices, reducing costs, or increasing sales — and instantly see how it affects your breakeven point and average profit per unit.

What’s the Heatmap feature? Select two products and visualize how changing their sales levels together affects your profit. The table color-codes your results: green = profitable, yellow = breakeven, red = losing money.

Can I download a summary? Yes! Go to the "Summary Report" section to generate a full printable breakdown of your products, expenses, profits, breakeven point, and more — perfect for sharing or saving.

💸 Cash‑Flow & Runway Planner

What’s the difference between an inflow and an outflow? Inflows add money to your balance (e.g. customer payments, loan draw‑downs). Outflows subtract money (e.g. rent, payroll, software bills). Enter outflows as − (negative) numbers so the planner can stack red bars on the chart and subtract them from your runway correctly.

Why do I need to set an “Opening Balance” first? That’s today’s cash in the bank. The planner uses it as the starting point for every calculation (weekly balances, burn rate, Monte‑Carlo forecast). If you leave it at zero, your runway will be zero too – even if you add inflows.

How is the 13‑week runway badge calculated? Each bar on the purple line is your running balance at the end of a week. The badge shows how many weeks remain before that line would dip below £0 if nothing changed.

Where does the “Burn rate: £X / month” number come from? The app looks at everything dated in the last 28 days, totals it, divides by 4 to get an average weekly net, then multiplies by 4.33 to express it as a calendar‑month figure. Positive burn means you’re losing money (badge turns red); a negative or zero burn shows you’re cash‑flow positive.

Why doesn’t the burn rate match the net difference I see in the table? The table footer sums all your future and past cash‑flows, while the burn‑rate averages only the most recent four weeks. This rolling window helps smooth one‑off spikes and gives a more realistic picture of how quickly you’re spending cash right now.

How is “Cash runway: N months” worked out? We divide your current balance (purple line’s latest point) by the monthly burn. Example: £10 000 in the bank and a £2 000/month burn ⇒ roughly 10 000 ÷ 2 000 = 5 months.

Why 13 weeks instead of 3 months on the main chart? Thirteen weeks = one business quarter. Many founders plan quarterly, and it keeps the chart readable without scrolling.

What’s a Monte‑Carlo forecast and why run 200 paths? It’s a way to model many possible futures by adding random “noise” around your current burn. Running 200 simulations lets you see a range of best‑, base‑, and worst‑case balances rather than a single straight line.

What do the “Pessimistic / Neutral / Optimistic” scenarios do? They change two parameters inside the simulation:
  • “Drift” (average monthly change)
  • “Volatility” (how wild each month can swing)
Pessimistic lowers the drift and keeps volatility high; optimistic raises the drift. Neutral sits in the middle.

Why does the chart look slightly different every time I click “Generate Forecast”? Each run produces new random numbers. Over many runs the trends even out, but the individual grey paths will vary.

How accurate is this tool? It’s only as good as the data you feed it. The forecast uses historical averages, which can’t predict sudden revenue drops or surprise bills. Treat it as a quick planning aid, not a guarantee.

Can I export or print my plan? Not yet. We’re working on a PDF export. For now, use your browser’s Print → Save as PDF or take a screenshot.

Is my data stored on your servers? No. Everything runs in your browser. Close the tab and the data vanishes unless you save it manually.

📦 Product Cost Calculator

What’s this tool for? To help you figure out how much it costs to make one unit of your product — whether it’s handmade, digital, or physical. Just add anything that contributes to production: materials, labor, packaging, shipping labels, and more.

How is it different from the Profit Calculator? This tool zooms in on the cost per unit of a single item. It’s great for getting the exact cost before you decide on pricing. The Profit Calculator zooms out — factoring in monthly revenue, labor, fixed expenses, and breakeven points to give a full business picture.

What is the “Type of Cost” field for? It’s optional but very helpful. You can tag each cost with categories like “Labor,” “Material,” or “Packaging.” This lets you generate charts showing how your total cost is split — so you can see which parts are eating into your margins.

Can I include my time? Yes, and you should! Just add a line item like “Labor (30 mins)” and enter what you’d like to pay yourself for that time. It’s the easiest way to start valuing your time as part of your production cost.

Can I add example data? Yep. Click the “Erm… I'm confused, fill below with an example product!” button and we’ll auto-fill with a sample (e.g., a candle with jar, label, and labor) so you can see how it works.

Does this work for digital or service-based products? Yes! Just skip material inputs and focus on time, subscriptions, or delivery costs. For example, a designer might include “1 hour of work” and “Adobe subscription.”

🍝 Food Dish Cost Calculator

How do I use this? Start by entering the ingredients used to make one serving of your dish. For each one, add how much is used per serving (like 200g of pasta), and how much that ingredient costs per gram, milliliter, or unit. The calculator totals the per-dish cost based on your entries.

How do I calculate cost per unit of measure? Take what you paid for the ingredient and divide it by the amount you bought. For example, if you paid £2 for 100g of cheese, then the cost per gram is £0.02. You can use grams (g), milliliters (ml), tablespoons (tbsp), or just enter a flat cost if it's a whole item (like one egg).

What’s the “Unit” field for? It’s optional and just helps you clarify the type of measurement — like grams, ml, etc. It’s especially useful if you’re using a mix of solids, liquids, or count-based items. Leaving it blank is totally fine for things like “1 egg” or “1 bun.”

Can I see a cost breakdown? Yes! Once you’ve added your ingredients, you’ll see a chart that shows how much each ingredient contributes to the total dish cost. This can help you spot expensive ingredients quickly.

Does this work for non-food items? Absolutely. While it’s designed with recipes in mind, you can use it for any product that involves combining components — like handmade candles, soaps, bath products, or DIY kits. Just think of each “ingredient” as a material.

Can I load an example? Yep! Hit the “Erm… I'm confused, fill below with an example dish!” button and we’ll auto-fill with a sample spaghetti plate to get you started.

❓ Quit-Readiness Quiz

What is this quiz for? It evaluates your financial runway, experience, risk profile and more, then gives you a 0–100 “Readiness to Quit” score plus an AI-generated action plan.

How does the scoring algorithm work? We aggregate twenty-two inputs into five broad buckets:

• Runway & Savings (max 45 pts): Based on your cash savings, monthly expenses, existing side-income and projected runway months.
• Business Foundations (max 30 pts): Validated idea, written plan, market research depth, and contingency measures.
• Experience & Support (max 20 pts): Years in industry, professional network strength, and spouse/partner backing.
• Personal Resilience (max 20 pts): Mental resilience, health status, and current burnout level.
• Risk Factors (–30 to +15 pts): Personal debt, dependents, funding gaps, job flexibility and age adjust your raw score up or down.

All buckets are normalized & clamped so your final score sits between 0 and 100.

What does my score mean? • 80–100: Green – you look well-prepared.
• 60–79: Yellow – promising but shore up a few gaps first.
• 40–59: Orange – caution: build more safety nets before leaping.
• 0–39: Red – high risk: strengthen your finances & plan before quitting.

How is the AI-generated plan created? After you finish, we send your answers and score to our AI service, which crafts a concise summary of your situation and a three-step action plan tailored to your highest-impact areas.
