Price Increase & Sales Loss

See how many sales you could lose after a price increase while preserving the same modeled profit. Test a volume-loss scenario against your current business.

Use price increase & sales loss →

Make vs Buy Cost

Compare two fixed-plus-variable cost plans over the same volume and period. See how the lower-cost option changes with volume and where the cost lines meet.

Use make vs buy cost →

Revenue Growth & CAGR

Compare total revenue growth with its smoothed compound annual rate over a stated positive number of years.

Use revenue growth & cagr →

Inflation & Input Costs

Compare an unchanged annual cost with a constant entered increase or decrease over a bounded planning horizon.

Use inflation & input costs →

Hotel Rate & Occupancy

Compare two entered ADR/occupancy scenarios after a channel-fee percentage and variable occupied-room cost. Demand remains your assumption.

Use hotel rate & occupancy →

Observed Price Elasticity

Compare midpoint and base-period quantity responses to a price change without interpreting two observations as a causal demand curve.

Use observed price elasticity →

Before you use these calculations

Define the base case, unit and time horizon before comparing scenarios.

Hold other assumptions constant when examining one change, then test the sensitivity to those assumptions.

Treat an elasticity, growth rate or discount rate as an entered assumption unless you have evidence for it.

Start with the example, replace the assumptions with your measurements, then change one input to see its effect. Save or export the scenario if you need to keep its basis.
