Lump sums promise something every mobility program wants: a simpler benefit for HR and more choice for relocating employees. They can be easy to administer, flexible enough to meet different needs and especially effective for employees with relatively straightforward moves.

But that simplicity can be deceptive. A lump sum only works when the amount, coverage and employee population are thoughtfully matched. Without that alignment, a benefit designed to create flexibility can quickly lead to confusion, exceptions and a poor relocation experience.

In general, lump sums are best suited to employees with fewer relocation needs, such as interns, early-career hires and recent graduates. These employees often have less complex moves, making them more likely to benefit from the flexibility a lump sum provides.

Beyond that, it’s also important to know if a lump sum program is right for your organization’s unique goals and budget.

That means there is no universal “magic number” for a lump sum.

Companies define these programs differently, and the expenses included can vary widely. Before setting an amount, mobility leaders need a clear picture of what the allowance is expected to cover, which employees will receive it and how the program supports the organization’s goals and budget.

With that in mind, here’s my playbook for determining the appropriate lump sum allowance for your company:

Top Tips for Smarter, Smoother Lump Sums

Evaluate the current lump sum. Start with the employee experience.

  • Are transferring employees asking for frequent exceptions?
  • Do they say the allowance falls short of the costs it is meant to cover?
  • Are candidates or employees declining moves?

These signals can reveal where the program is missing the mark. If you do not have this insight, gather structured feedback from employees, managers and other key stakeholders.

Define the lump sum as specifically as possible. Avoid broad labels such as “house-hunting trip.” Spell out the expenses the allowance is intended to cover, including the number of travel days, meals, transportation and whether costs for a spouse or children are included. Clear parameters help employees budget confidently and reduce confusion about what the benefit is designed to support.

Clearly define who is eligible for a lump sum—and who may need a more supported approach. A recent graduate, for example, is unlikely to face the same expenses or logistical demands as a mid-level homeowner, even when both allowances cover similar provisions. Executives and many homeowners typically have more complex moves to coordinate, making a fully managed benefit a better fit than asking them to manage a lump sum on top of everything else.

Calculate the average cost of each benefit across your most common move corridors (i.e.  Boston to Chicago). Where appropriate, build different estimates by employee level or tier and by homeowner or renter status. Adding those costs together provides an estimated cost per employee and helps establish the upper end of the lump sum range. The latest research shows that half of companies provide $10,000 or less, while amounts typically rise with employee level and move complexity. Be sure to account for gross-up as well.

Decide whether a total or partial lump sum is the better fit for each employee group or tier. A total lump sum offers maximum flexibility, while a partial approach can preserve support for more complex or business-critical services. Keep in mind that once a total lump sum is in place, it becomes more difficult to see how employees use the allowance and what future policy enhancements may be needed.

Choose an amount-setting approach that fits your company’s financial culture and program goals. The latest policy analysis found that 58% of programs rely on business discretion, while 14% use a fixed amount defined in policy, 11% use distance, 8% use a third-party tool, 6% use homeowner or renter status and 3% use salary. The right method should be clear enough for employees to understand and consistent enough for the organization to administer.

Determine the amounts based on the calculation method. Use conservative amounts that encourage employees to be resourceful, but not so low that they impede mobility or create negative feelings among employees.

Lastly, and this is important, whatever lump-sum approach your company uses, you should plan to reassess your program regularly. Ask for candid feedback from employees who’ve received lump sums regarding their experiences. Solicit input from managers, too. Were the initial estimates accurate? Is your method of calculating the lump sum meeting employee expectations? Are there instances of misuse or double-dipping?

The resurgence of lump sums in the industry reflects that they’re easy to implement and offer the greatest flexibility. But it’s important to be vigilant; without guidance or planning or knowledge of the process, your lump sum program can quickly swing from blessing to curse.
