Questions
- How many units do you need to sell to break even?How to work out the number of units you must sell to cover your fixed costs, the revenue that takes, and when breaking even is impossible.
- Does my monthly store plan go under fixed costs and the per-order commission under variable cost?Your monthly store plan is a fixed cost; a commission taken on every order belongs in the variable cost per unit. A worked example shows what mixing them hides.
- As a freelance designer in Dubai, how many billable hours a month do I need just to cover my costs?Make one billable hour the unit in the break-even calculator: your rate is the price, your monthly overheads are fixed costs. Worked example at two hourly rates.
- Which lowers my break-even more: a 10% price increase or a 10% cut in product cost?A worked comparison on one product: a 10% price rise cut break-even from 500 to 400 units, a 10% cost cut only to 435. Why the price lever usually wins on paper.
- I run a coffee cart: how many cups a day must I sell to cover the monthly rent and wages?Work out the monthly break-even for a coffee cart, then turn it into a daily target: 77 cups a day at a price of 14 in this worked example, 63 cups at 16.
- If I offer free shipping and absorb the courier cost myself, how many more orders do I need to break even?Free shipping leaves fixed costs alone but raises the cost of every order. Worked example: 25 of shipping pushed break-even from 134 orders to 229.
- Selling on Amazon.sa with FBA, where do referral and fulfilment fees go in a break-even calculation?Referral and fulfilment fees are charged per unit, so they belong in variable cost; a monthly seller plan is fixed. An illustrative example shows how fee-sensitive it is.
- Why does a 20% White Friday discount double the number of units I need to cover my costs?A discount comes out of your contribution, not the whole price. Worked example: 20% off moved break-even from 500 units to 1,000, and 40% off removed it entirely.
- I paid an influencer 3,000 for one campaign: how many units must that campaign sell to pay for itself?Make the influencer fee the fixed cost of the campaign and enter the promoted product's price and cost. Worked example: 75 units at full price, 97 with a discount code.
- Some of my costs are annual, like a licence renewal and a yearly website plan: should I calculate break-even monthly or yearly?Both work, as long as costs and sales cover the same period. A worked example shows how dropping a yearly cost into one month's figures inflates break-even.
- I put the cost of the stock I bought from my supplier into fixed costs and the break-even came out huge: what went wrong?Stock you buy to resell is already in your unit cost; adding the invoice to fixed costs counts it twice. Example: 667 units by mistake against 167 done right.
- I cannot decide between pricing at 79 or 99: how do I compare the sales each price needs to break even?Run break-even for each price with the same costs, then ask whether the lower price really sells the extra units it needs. Worked example: 177 units against 112.
- What does the contribution margin ratio mean, and how does it give my break-even revenue directly?The contribution margin ratio is the share of every sale left to cover fixed costs. Divide fixed costs by it to get break-even revenue directly. Two worked examples.
- I want a monthly profit of 5,000, not just to break even: how many units does that take?Add the profit you want to your fixed costs in the break-even calculator and the result becomes the units that profit needs. Worked example: 750 units instead of 500.
- Are my cost and price figures sent to a server when I use the break-even calculator?No. The calculation runs in your browser, and the figures you type are neither uploaded nor saved. What that means for confidential supplier costs and shared computers.
- My payment gateway charges a percentage plus a fixed amount per transaction: how do I turn that into a variable cost per unit?The variable cost field takes an amount, not a percent, so work the fee out on your selling price and add it to unit cost. Example: 2.5% plus 1 on a price of 200 is 6.
- I sell a three-piece bundle at one price: how do I calculate break-even for the bundle rather than per piece?Treat the bundle as the unit: its price is the unit price and the three pieces plus packaging are the variable cost. Worked example: 110 bundles, or 330 pieces of stock.
- My shop sells dozens of products at different prices: can a single-product break-even calculator still help?The calculator does not model a product mix, but two honest workarounds do: an average order as the unit, or each product line with its share of fixed costs.
- How do I include the cost of cash-on-delivery orders that customers refuse in my break-even?The calculator does not model returns, but you can spread refused orders' cost over paid ones. Example: a 10% refusal rate moves break-even from 91 paid orders to 97.
- Why does the calculator say I am at break-even with zero sales when my dropshipping store has no fixed costs?With no fixed costs there is nothing to cover, so the calculator shows 0 units. Most stores have forgotten fixed costs, and a worked example shows them appear once added.
- If I hire my first employee at 4,000 a month, how many extra units must I sell each month to cover the salary?Enter the new salary alone as fixed costs, with your usual price and cost, to see the extra sales the hire has to support. Example: 115 units, 132 with the extras.
