Recruiting background-check timeline calculator

Calculate latest parallel initiation days and initiation lateness by check with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use latest parallel initiation days and initiation lateness by check to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

JSON Required checks [ID,supplied duration days]
[["identity",3],["references",8]]
Planned start day from chosen origin
20
Current day from same origin
15
Latest parallel initiation days
[["identity",17],["references",12]]
Initiation lateness by check (days)
[["identity",0],["references",3]]
Latest common initiation day
12

Calculation method

Calculation method

Latest parallel initiation days

J([[r[0],b-r[1]] for r in a])

Initiation lateness by check (days)

J([[r[0],max(0,c-(b-r[1]))] for r in a])

Latest common initiation day

b-max(r[1] for r in a)

Symbols and units
a
JSON Required checks [ID,supplied duration days]
b
Planned start day from chosen origin
c
Current day from same origin

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Checks assumed parallel and their provider lead times supplied. This does not judge required legal checks or guarantee completion. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
