Metrics & formulas

Every derived figure in bluprnts and how it's calculated — margins, runway, breakeven, burn, max cash needed, working capital and short-term cover.

Every figure bluprnts derives from the statements, and the calculation behind it. All of them are projections of the statements, which is why they always agree with them.

Trading#

MetricCalculation
RevenueSum of the revenue lines over the period
Gross profitRevenue − cost of sales
Gross marginGross profit ÷ revenue
Operating profit (PBIT)Gross profit − operating costs − depreciation
Operating marginOperating profit ÷ revenue
Profit before taxOperating profit + net interest
Profit after taxProfit before tax − tax
Net marginProfit after tax ÷ revenue
Revenue growthThis year's revenue against last year's
Average monthly profitProfit after tax ÷ months in the period

Cash#

MetricCalculation
Opening cashThe bank balance the forecast starts from
Closing balanceThe bank balance at the end of the window
Incoming / OutgoingTotal cash in and out over the period
Net flowChange in balance ÷ months
Cash low pointThe lowest the closing balance reaches, and the month
Max cash neededThe magnitude of the deepest point — the largest hole the plan has to fund
Average monthly burnAverage net outflow across the months that burn cash

Survival#

MetricCalculation
RunwayThe number of months before the closing balance first goes negative. Fully funded when it never does — across the modelled period only
Cash runs outThe month the balance first goes negative
BreakevenThe month profit after tax holds from. No breakeven when the plan never turns profitable

Balance sheet#

MetricCalculation
Total assetsCurrent + non-current assets
Total liabilitiesCurrent + non-current liabilities
Net assetsTotal assets − total liabilities
Working capitalCurrent assets − current liabilities
Short-term cover (current ratio)Current assets ÷ current liabilities. A dash when nothing is owed short-term

Per unit#

MetricCalculation
Revenue per unitRetail price + shipping price
Cost per unitProduction + storage & distribution + shipping cost
Margin per unitRevenue per unit − cost per unit
Margin %Margin per unit ÷ revenue per unit

Two things worth knowing#

Runway is measured against the modelled period. A forecast that ends before the cash does reports Fully funded, which is true of the window and says nothing beyond it. See Forecast window.

Max cash needed is the number to fund against, not the closing balance. A plan can end the year comfortably and still need a large facility to get through month five.
