Hiring vs Promotion Calculator — Which Actually Costs Less for Your Open Role?

When a senior role opens up, most organizations default to one of two options — promote someone internally or hire externally — without rigorously comparing the true financial cost of each. The result is a decision driven by gut feel, politics, or whichever option is most visible, rather than the one that's actually better for the business. The Hiring vs Promotion Calculator computes the total 24-month cost of each path across six dimensions: Recruiting Cost (agency fees, job board spend, interview time), Ramp Time Cost (how long before the person is fully productive, and what that gap costs), Compensation Delta (the salary difference between an external hire and the promoted employee, plus any backfill cost), Training & Onboarding (all development required to bring either person to full capability), Retention Risk (the probability each path leads to departure in 24 months, and the cost of replacing them), and Culture & Team Impact (estimated cost of team disruption, morale effects on the team that was passed over, and knowledge transfer). The result is a side-by-side 24-month total cost comparison, a break-even analysis showing when each option becomes more expensive than the other, and a recommendation with the specific factors that drive the difference. Most organizations are surprised: external hires typically cost 40–80% more than promotions on a true 24-month basis.
