Why use this calculator
Price is the fastest lever in any business and almost nobody pulls it deliberately. Most small firms set a price once by adding a margin to cost, then defend it for years while costs drift upward, and discount whenever a customer pushes. That is backwards on both counts.
A price rise flows almost entirely to the bottom line because the cost of delivering the unit does not change, so a five per cent rise on a typical margin lifts gross profit by ten per cent or more. A discount works the other way and much harder: at a fifty per cent gross margin, a ten per cent cut needs a twenty-five per cent lift in volume just to stand still, and that volume brings extra delivery cost, extra support and extra risk with it.
This calculator puts the three classic pricing approaches beside each other, shows what each does to monthly profit, and quantifies the volume swing behind any change you are considering.
How to use it
- Enter the direct cost of delivering one unit, counting materials, freight, packaging, payment processing and the labour that varies with volume, but leaving rent and salaried staff out because those belong in fixed costs.
- Enter the price you actually charge today after typical discounts, taken from last month's invoices rather than your price list.
- Set the target gross margin your business model needs, then enter the advertised price of the closest substitute a buyer would seriously consider and how far below it you would be willing to sit.
- For value to the customer, enter what the buyer saves or earns by using your product, or the cost of their next best alternative, and set the share of that value you intend to capture.
- Add average units sold a month over the last quarter rather than your best month.
- Finally set the size of price change you want to model.
What each result means
- Cost-plus price
- The price that delivers your target gross margin on this unit cost. Safe, defensible, and usually the lowest of the three.
- Competitive price
- Your price if you simply sit below the closest substitute. It anchors you to a rival's cost base rather than your own.
- Value-based price
- The price implied by what the buyer gains, which is the only method with real upside when you are genuinely differentiated.
- Suggested price band
- The span between the lowest and highest of the three methods. Choose a point inside it and be able to explain why.
- Contribution per unit today
- Price minus direct cost on your current price. This is the money each sale contributes to fixed costs and profit.
- Gross margin today
- Contribution as a share of price. Compare it to the norm for your sector before deciding you are expensive.
- Monthly gross profit today
- What your current price earns each month before fixed costs. It is the baseline every option is measured against.
- Monthly gross profit at cost-plus
- Monthly gross profit if you moved to the cost-plus price, assuming volume holds. Usually the weakest of the three.
- Monthly gross profit at competitive
- Monthly gross profit at the competitor-anchored price, again assuming your volume does not move.
- Monthly gross profit at value-based
- Monthly gross profit at the value price. The gap against today is the money differentiation is worth to you.
- Monthly profit after the price rise
- Gross profit after the rise you modelled, at unchanged volume. The increase is almost pure profit because costs do not move.
- Volume you can afford to lose
- How far sales could fall after the rise before you are worse off. It is usually much more than owners fear.
- Extra volume needed after a discount
- The sales lift a discount of the same size would need just to break even. It is usually far more than a discount ever delivers.
The formula
Cost-plus price = unit cost divided by (1 minus the target gross margin), which is the margin formula rather than the markup formula and is where most spreadsheets go wrong
Competitive price = competitor price multiplied by (1 minus the undercut percentage)
Value-based price = value to the customer multiplied by the share of value you capture
Contribution per unit = price minus unit cost
Gross margin = contribution divided by price
Monthly gross profit = contribution multiplied by units sold
For a price change, volume you can afford to lose = 1 minus (old contribution divided by new contribution)
The extra volume a discount needs = (old contribution divided by discounted contribution) minus 1
How this number is used in practice
The arithmetic of discounting is the single most useful thing an owner can internalise. Take a business selling at $42 with a $22 unit cost, a contribution of $20 and a gross margin just under 48 per cent. A five per cent discount takes the price to $39.90 and the contribution to $17.90, so you now need almost twelve per cent more units to earn the same gross profit, and those extra units consume more stock, more delivery and more support.
Push the discount to ten per cent and the required lift is over twenty-five per cent. Run the same numbers on a thin-margin trade business where the job costs $180 and is quoted at $220 and a ten per cent discount more than doubles the work needed to stand still.
Discounting is not a growth tactic on any margin below about seventy per cent, it is a transfer of your profit to the customer.
The rise works with exactly the same leverage in your favour. Five per cent on that $42 price adds $2.10 of pure contribution per unit, lifting monthly gross profit from $10,000 to $11,050, an increase of over ten per cent from a change most customers will not notice on an invoice.
The calculator shows you could lose nine and a half per cent of your volume and still be no worse off, which is far more headroom than most owners expect. Sector benchmarks are worth knowing before you decide you are expensive: grocery retail runs on gross margins in the twenties, general retail around forty to fifty, hospitality food cost around thirty per cent of the menu price, professional services fifty to seventy, and established software seventy-five to eighty-five.
If you are meaningfully under the band for your sector, the problem is usually your price rather than your costs.
Choosing between the three methods is really a question about differentiation. Cost-plus is a floor and a sanity check, never a strategy, because it prices your inefficiency rather than your customer's need. Competitive pricing makes sense in genuinely commoditised markets, but anchoring to a rival means inheriting their cost structure and their mistakes, and undercutting invites a response you will probably lose.
Value-based pricing is the only method with real upside, and it requires two things: knowing what the customer actually gains in dollars, and being able to say it out loud in a sentence. Most businesses can move a long way toward value pricing simply by asking their best ten customers what they would have paid and what problem the purchase solved.
Worked examples
A product costing $22 to deliver, priced at $42 today, 45% target margin, $45 competitor price undercut by 5%, $70 customer value at 75% capture, 500 units a month, testing a 5% move
Cost-plus $40.00, competitive $42.75, value-based $52.50, and a 5% rise lifts monthly gross profit from $10,000 to $11,050
A software subscription with $6 of delivery cost priced at $39, an 80% target margin, a $49 competitor, $200 of value at 40% capture, 800 subscribers and a 10% test
Value-based pricing at $80.00 more than doubles monthly gross profit against the $26,400 earned today
A low-margin trade job costing $180 to deliver and quoted at $220, testing a 10% discount to win more work
The discount cuts contribution from $40.00 to $18.00 and needs 122.2% more volume to break even
When people use it
- Setting the launch price for a new product or service
- Deciding whether to pass a cost increase through to customers
- Testing what a proposed discount or promotion really costs in volume terms
- Building the case for a premium price against a cheaper competitor
- Reviewing prices annually against cost drift and competitor moves
- Working out how much market share you could lose and still be better off after a rise
Tips
- Raise prices on new customers first. You get a clean read on demand without risking a single existing relationship.
- Never discount without a matching concession such as a longer term, prepayment, a larger order or a case study.
- Round prices upward to a confident number. Ending in 9 signals value, ending in 0 or 5 signals quality, and both beat an odd calculated figure.
- Offer three tiers. A deliberately expensive top option reliably lifts the average sale by making the middle option look sensible.
- Check the margin formula before anything else. Dividing by one minus the margin gives a margin, multiplying by one plus the rate gives a markup, and they are not the same.
- Move small and often. A yearly rise of three to five per cent is invisible, while a one-off twenty per cent correction every five years costs you customers.
- Ask your last ten buyers what they compared you against. Their answer defines your real competitive price far better than your own market view.
What it assumes, and where it stops being accurate
- Assumes volume stays constant when comparing prices. Real demand responds to price, which is exactly why the break-even volume columns exist.
- Assumes unit cost is genuinely variable. Loading fixed costs such as rent or salaries into unit cost inflates the cost-plus price and makes you uncompetitive.
- Uses the gross margin formula, not markup. A 45 per cent margin is a markup of about 82 per cent, and confusing the two is the most common pricing error in small business.
- Ignores discounting structures, freight recovery, payment terms and bad debts, all of which reduce the price you actually realise.
- Ignores competitor response. A visible undercut frequently triggers a matching cut that leaves both businesses worse off at the same market share.
- Ignores any consumption tax such as GST, VAT or sales tax, which should be excluded from both price and cost when calculating margin.
Terms used on this page
- Contribution margin
- Selling price minus the variable cost of delivering one unit, the money each sale contributes to fixed costs and profit.
- Gross margin
- Contribution expressed as a percentage of the selling price, the standard measure for comparing pricing across a sector.
- Markup
- Profit expressed as a percentage of cost rather than of price, always a larger number than the equivalent margin.
- Cost-plus pricing
- Setting price by adding a target margin to unit cost, which ignores what the buyer is willing to pay.
- Value-based pricing
- Setting price from the measurable benefit the customer receives rather than from your own costs or a rival's price.
- Price elasticity
- How much demand changes when price changes. Low elasticity means you can raise prices with little volume loss.
Questions people ask
- Which pricing strategy should I actually use?
- Use cost-plus as a floor so you never sell below a viable margin, use competitive pricing only where the product is genuinely interchangeable, and use value-based pricing wherever you can name in dollars what the customer gains. Most businesses should land near the value price and use the other two as sanity checks rather than as the decision.
- Why does a small discount need such a large increase in volume?
- Because the discount comes entirely out of contribution, not out of revenue. On a fifty per cent margin a ten per cent price cut removes a fifth of your contribution per unit, so you need a quarter more units to replace it, and those units cost more to deliver and support. The lower your margin, the more brutal the arithmetic becomes.
- How do I work out what my product is worth to a customer?
- Quantify the alternative. Ask what they would do if you did not exist, what that option costs them in money and time, and what your product saves or earns in a year. Then ask your best customers directly what they would have paid. The answers are usually well above your current price.
- Is it safe to raise prices in a competitive market?
- Usually safer than owners assume. Customers buy on convenience, trust and switching cost as much as on price, and a single-digit rise rarely triggers a search for alternatives. Model the volume you could afford to lose first, then raise prices on new customers and watch conversion before rolling it out to everyone.
- What is the difference between margin and markup?
- Margin is profit as a share of the selling price, while markup is profit as a share of cost. A 45 per cent margin on a $22 cost gives a $40 price, which is a markup of about 82 per cent. Using markup where you meant margin systematically underprices, and it is the most common arithmetic error in small business pricing.
- Should I price below my competitor to win work?
- Only if you have a genuine cost advantage you can sustain. Undercutting an equal competitor invites a matching cut, and you both end up at lower prices with the same market share. Differentiating on speed, guarantee, specialisation or service is almost always cheaper than buying share with margin.
