02 Hiring

Leadership gap calculator

Our product leader is leaving. How long is the gap, what will it cost, and does interim cover pay for itself?

For CEOs, CFOs and hiring managers. Takes about four minutes. Opens with example numbers.

Your numbers

1The timeline

The role

Head of Product VP Product Chief Product Officer

Notice the outgoing leader still has to serve

Time to find the new leader and sign the offer

Search firms plan about 3.5 to 4 months for VP roles and about 4 for C-suite roles.

Where the new leader works today

Their notice period

Time for them to reach full effect

A quarter is common. Watkins put the break-even point for new leaders at just over six months.

2The money

Currency

Yearly cash cost of the role

Search fee, as a share of first-year cash

Retained search usually charges 25 to 35%. One third is common.

People whose work depends on product decisions

Their average yearly cost

Share of their work that drifts to lower-value tasks without a product leader

Your estimate. Work still ships, but on what was loudest instead of what matters most.

Revenue held up per month of delay

Leave at 0 unless a launch or a deal waits on product decisions.

3The people risk

Product managers on the team

Their average yearly cost

Chance each one leaves, per quarter without a leader

Cost to replace one, as a multiple of yearly cost

Gallup puts replacement cost at half to two times annual salary.

4The options

Interim cover: an experienced product leader who runs the team until the new hire settles in.

Interim cost per month

Starts this many weeks after the resignation

Overlap with the new leader for handover

Drift that interim cover prevents

Exit risk that interim cover prevents

Split the role: the CEO and CTO cover product between them.

CEO and CTO yearly cost, combined

Share of their time it takes

Drift that the split prevents

5Decisions that can't wait

Product decisions due in the next months. The tool shows which fall in the gap, who should make them, and what to hand over.

6What the outgoing leader has written down

The answer

Weeks without full product leadership

Cost of waiting for the hire

Saved with interim cover

The line from resignation to full effect

Outgoing leader's notice Empty seat New leader ramping up Interim cover

Red notes show what usually breaks, in order, while the seat is empty. Timing varies by company.

How this tool works

What it does

It lays out the time from your product leader's resignation to the moment the new leader is fully effective. Then it prices the gap three ways: wait for the hire, bring in interim cover, or split the role between the CEO and CTO.

Use it in the week someone resigns, when you decide how to cover the role.

What you enter

Timeline. Notice left on the outgoing leader, search time to a signed offer, the new leader's notice period and ramp-up. Picking one of 56 countries fills in a typical senior notice period. Change it to match the contract.
Money. The role's cost, the search fee, the people who depend on product decisions and how much of their work drifts without a leader.
People risk. The chance each product manager leaves while the seat is empty, and what replacing one costs.
Options. What interim cover costs and how much drift and exit risk it prevents, and the same for a CEO and CTO split.
Decisions and handover. Up to five decisions from a list of 27, with due week, how reversible each is, and who decides now. Then what the outgoing leader has written down.

What you get

Weeks without full product leadership. The empty seat plus the new leader's ramp-up.
The timeline. Each milestone by week, with the usual order of what breaks.
The options table. Each path's total cost. The cheapest is circled.
The break-even search length. How long the search must run before interim cover pays for itself.
Decisions that can't wait. Each decision placed on the timeline: before the leader leaves, in the gap, or for the new leader. Each gets an action.
A handover plan in three phases, and a PDF report for the leadership team.

The maths, assumptions and sources

Empty seat = search time + new leader's notice − outgoing leader's remaining notice. During ramp-up the new leader is treated as half effective, so drift counts at half weight. Drift cost = people × yearly cost × drift share × weeks ÷ 52. Exit risk compounds by quarter: expected leavers = product managers × (1 − (1 − quarterly chance)^{weeks ÷ 13}). The role's salary isn't paid while the seat is empty, so the tool subtracts it. Interim cover runs from its start week until the overlap with the new leader ends. The split costs the share of CEO and CTO time it takes while the seat is empty.

Notice periods: the United Arab Emirates allows 30 to 90 days by law. Saudi Arabia requires 30 days from employees on open-ended contracts since February 2025. In India, 90 days is common for senior roles. In the UK, three-month notice clauses are common. In Germany, senior roles often need two to three months. In the United States there's no legal minimum, and two weeks is customary. These are typical contract terms, not legal advice.
