Time to Hire Capacity Gap Calculator

Check whether current recruiting capacity can support a monthly hiring target at the present time to hire. The calculator estimates concurrent requisitions required, the capacity shortfall or surplus, and the hiring pace supported by available capacity.

How to use this calculator

  1. Enter values that use the same reporting period and definition.
  2. Review units and adjust assumptions to match your organization.
  3. Select Calculate to update the result.
  4. Compare the main result and supporting metrics, then test an alternative scenario.

Formula

Required concurrent capacity = Monthly hiring target × Time to hire ÷ 30.4375. Supported hires per month = Available capacity × 30.4375 ÷ Time to hire.

What the result means

Use the main result as a scenario estimate and read the supporting metrics to understand what drives it. Compare current and target cases with consistent definitions.

The model assumes a steady flow and one filled requisition per hire; seasonality and requisitions with multiple openings require adjustment.

Example calculation

A target of 20 hires per month at 45 days requires 29.6 concurrent requisitions. With capacity for 24, the gap is 5.6 roles.

Tips for better results

  • Use cohort-based data when possible.
  • Document the source and date of each assumption.
  • Separate role groups with materially different costs or timelines.
  • Change one input at a time during scenario analysis.
  • Reconcile planning estimates with ATS and finance reports.

Frequently asked questions

What inputs should I use in the Time to Hire Capacity Gap Calculator?

Use figures from the same reporting period and apply one consistent definition to every input. The help text beside each field describes the expected unit.

Can I enter zero in this calculator?

Zero is accepted where it represents a valid count, cost, or rate. Inputs used as divisors must be greater than zero so the result remains defined.

Does the result represent an accounting expense?

Not necessarily. The calculator is a planning model based on the values you enter. Confirm accounting treatment with your finance team before using it in reported statements.

How should I compare scenarios?

Calculate the current case, record the result, then change one assumption at a time. This makes it easier to see which input drives the difference.

Why might the estimate differ from our ATS report?

Applicant tracking systems may use different cohort dates, stage definitions, exclusions, or rounding. Align those definitions before comparing results.
