Models M&A or partnership synergies with a bundled calculator that ramps cost and revenue synergies realistically over time, applies a confidence haircut to revenue synergies (historically far less reliable than cost synergies), and nets out integration costs to a true synergy-case NPV. Use whenever the user is building or reviewing a deal case, needs to size expected synergies from an acquisition or partnership, or has a synergy number that's presented as available immediately at full run-rate with no ramp, no haircut, and no integration cost netted out.
