Diagnostic Tool
Revenue Shock Impact Simulator
This diagnostic estimates the financial impact of losing a major customer, segment, or revenue stream. It models how the concentration of revenue in a small number of sources creates hidden profit fragility that is not visible when reviewing total revenue or overall growth rates.
In operating businesses, revenue shocks occur when a major customer relationship ends, when a dominant product category is disrupted, or when a key contract is not renewed. The impact on profit is typically far greater than the revenue loss alone suggests, because the fixed cost base remains intact while contribution evaporates. The business must suddenly operate with a significantly smaller gross profit against an unchanged overhead structure.
Understanding revenue shock impact matters because it quantifies the true financial exposure behind a concentration position. Most businesses intuitively understand the risk, but quantifying the exact profit impact, the break-even adjustment required, and the timeline to recovery provides the analytical foundation for decisions about diversification, contract management, and cost structure flexibility.

Fixed costs per month that remain even without this revenue.
Available cash to absorb losses while the revenue gap is addressed.

Estimated months needed to rebuild the lost revenue from new sources.
Percentage of fixed costs that could be reduced within 90 days.
Many of the inputs requested by this diagnostic are metrics that disciplined operators typically monitor through internal management reporting. If a number requested here is not immediately available it often indicates that the current reporting structure does not isolate that metric clearly. Businesses operating with strong financial visibility normally track these figures regularly because they influence pricing decisions, supplier negotiations, operational planning, capital allocation, and risk management. Part of the work performed by MJB Strategic often involves helping companies design internal reporting structures that surface these metrics consistently so management can make better operational decisions.
