How the calculation works
What the ramp period costs
New hires build productivity as they learn the role, systems, and team. The calculator uses fully loaded pay to estimate the cost of that ramp, so you can plan hiring and onboarding budgets.
The six-month ramp estimate draws on an Oxford Economics study of five UK sectors, which reported approximately 28 weeks to full productivity. The starting productivity estimate of 25% is a planning assumption.

How the estimate is calculated
The calculator assumes productivity rises evenly from the starting percentage to 100% over the ramp period. Average productivity is the midpoint. Multiply the remaining productivity gap by fully loaded monthly cost and ramp months, then add direct onboarding expenses.
For example, a $70,000 role with a 30% benefits load costs approximately $7,583 per month. At 25% starting productivity over six months, average productivity is 62.5%. The estimated productivity cost is $17,063, before onboarding expenses.
How ramp time affects cost
Starting productivity and ramp length have the greatest effect on the estimate. With all other figures unchanged, cutting either the ramp time or the starting productivity gap in half also cuts the estimated productivity cost in half. Preparing tools, system access, and orientation before day one helps new hires begin contributing sooner.
Help new hires reach full productivity sooner
A structured 30-60-90 day plan gives new hires clear milestones and managers a consistent check-in schedule. An onboarding buddy helps employees learn the day-to-day work. Have equipment, system access, and initial assignments ready before the start date. Your annual hiring figures show what a faster ramp could save.
