Inputs that matter most
Understanding how each variable impacts the final calculation
Current Cash Reserves
The primary value establishes the baseline magnitude for the entire calculation model.
Monthly Net Cash Burn
The rate or percentage factor determines how the baseline value expands, discounts, or incurs expense over the modeled period.
