Break-Even Point: 1000 Units/Month at SGD 50 Price (Below This = Loss)
Restaurant: fixed costs SGD 30K/month (rent, utilities, staff). Variable cost per meal SGD 8 (COGS). Menu price SGD 20/meal. Contribution margin: SGD 20 - SGD 8 = SGD 12/unit. Break-even: SGD 30K ÷ SGD 12 = 2500 meals/month. Below 2500 = loss. Above 2500 = profit. Daily BEP: 2500 ÷ 30 days = ~85 meals/day. If you sell 100 meals/day, profit = (100 - 85) × SGD 12 = SGD 180/day = SGD 5.4K/month profit.

The Break-Even Formula#
BEP (units) = Fixed Costs ÷ Contribution Margin Per Unit. Contribution Margin = Price - Variable Cost. Example: price SGD 50, variable cost SGD 30, contribution = SGD 20. Fixed costs SGD 100K/month. BEP = SGD 100K ÷ SGD 20 = 5000 units/month.
Understanding Fixed vs Variable Costs#
Fixed: rent, insurance, depreciation (same whether you sell 1 unit or 1000). Variable: COGS, shipping, payment processing (change with volume). This distinction matters for BEP: higher fixed costs = higher BEP = more risk (must sell a lot to avoid loss). Higher variable costs = lower contribution margin = higher BEP.
BEP as a Safety Margin#
If BEP = 5000 units/month and you expect to sell 6000, safety margin = 1000 units (17% cushion). If actual demand drops 17%, you break even (zero profit/loss). <10% safety margin = too risky. >20% safety margin = comfortable (likely profitable).
AskBiz Break-Even Calculation#
Inputs: fixed costs, variable cost per unit, selling price. Outputs: BEP in units/month, BEP in revenue, safety margin (% above expected sales). "Fixed costs SGD 30K, variable SGD 8/unit, price SGD 20, expected demand 3000 units. BEP: 2500 units. Safety margin: 500 units (16.7% above BEP). If actual sales drop 17%, you lose money. Recommendation: reduce fixed costs to SGD 25K (landlord negotiation), lower BEP to 2083 units, increase safety margin to 25%."
Break-Even in Revenue Terms, Not Just Units#
For businesses selling multiple products at different prices, unit-based BEP doesn't work directly — you need break-even in revenue terms instead. BEP (revenue) = Fixed Costs ÷ Contribution Margin Ratio, where Contribution Margin Ratio = (Price − Variable Cost) ÷ Price, expressed as a blended average across your product mix weighted by sales volume. If your blended contribution margin ratio is 40% and fixed costs are SGD 30K/month, BEP (revenue) = SGD 30K ÷ 0.40 = SGD 75K/month in sales, regardless of exactly which products make up that revenue. This is the more practical version of the formula for a shop or restaurant with a varied menu or product catalogue, because you rarely sell only one SKU. Recalculate the blended margin ratio whenever your product mix shifts meaningfully — a menu change or a shift toward higher-margin items changes your BEP even if fixed costs stay flat.
Worked Example: Deciding Whether to Take On More Rent#
A café was considering a larger unit at SGD 8K/month rent versus its current SGD 5K/month, a SGD 3K increase in fixed costs. Current numbers: fixed costs SGD 22K/month total, contribution margin per coffee SGD 3.50 (price SGD 5.50, variable cost SGD 2), current BEP = SGD 22K ÷ SGD 3.50 = 6,286 cups/month, current actual sales 8,200 cups/month (30% safety margin). With the new rent: fixed costs rise to SGD 25K/month, new BEP = SGD 25K ÷ SGD 3.50 = 7,143 cups/month. The bigger space was projected to support 20% more covers, implying roughly 9,840 cups/month — a safety margin of 27.6%, only marginally tighter than the current 30%. This calculation, run before signing the lease, confirmed the move was financially sound as long as the capacity increase materialised; without it, the new BEP would have eaten most of the café's safety cushion.
Common Mistakes in Break-Even Analysis#
The first mistake is misclassifying semi-variable costs as purely fixed or purely variable — utilities, for example, have a fixed base component and a variable component tied to production volume, and lumping the whole bill into "fixed" overstates your BEP risk. The second is calculating BEP once at the start of the year and never updating it as costs change — a rent increase, a new hire, or a supplier price rise all shift the BEP and should trigger a recalculation, not be absorbed silently into a shrinking safety margin nobody notices until cash gets tight. The third is ignoring BEP entirely when making growth decisions, like adding staff or expanding premises, without first checking how much the added fixed cost raises the sales volume you need just to stay even. AskBiz recalculates BEP automatically whenever fixed costs or pricing change, so the safety margin is always current rather than based on a stale annual calculation.
People also ask
How do I use BEP for pricing?
Set price such that expected volume is well above BEP (20%+ safety margin). If BEP is 5000 and expected demand is 5200, price too high (insufficient margin). Adjust down (raise volume, lower BEP cushion), or reduce fixed costs.
Should I always target profit above BEP?
Yes. Operating at BEP (zero profit) is risky (any demand drop = loss). Target 20-30% above BEP for safety. For growth, reinvest profit into expansion (which raises fixed costs, requires higher volume to cover).
