Katelyn is VP Customer Success of Comprehensive, a compensation platform for automating compensation reviews, communicating compensation with employees, managing pay ranges, and benchmarking.
Every company designs its own compensation strategy. You decide how raises get determined, how bonuses are earned, and what rules apply to whom. The hard part is not designing that strategy but running it.
Many compensation software platforms only handle a fixed set of logic. The moment your strategy has a wrinkle the tool cannot express (e.g., a rule that varies by country, a floor that has to be met, or a bonus with more than one moving part), you are back in a spreadsheet, doing it by hand.
This is why so many companies moved salary reviews into software but still run bonuses in a spreadsheet. The bonus logic was simply more than the software could handle. It was never that these teams preferred spreadsheets. It was that finding an overall comp software that handles bonuses, too, was a challenge.
Custom compensation formula software closes that gap. It is built so the software matches your strategy instead of forcing your strategy to match the software. Whatever the logic, for salaries or for bonuses, it runs inside the compensation cycle. You keep the flexibility a spreadsheet gives you and lose the manual work, the version chaos, and the risk that comes with it.
A spreadsheet can hold almost any compensation logic you build. The problem is what happens after you build it.
The first risk is key-person dependence. The intricate formulas were usually built by one person, and when that person leaves, the knowledge leaves with them. The team keeps running the same sheet every cycle, aware that it is fragile and that no one fully understands it anymore.
The second is version chaos. Take your comp rules, multiply per manager, then multiply again by each level of approval. The result is a pile of spreadsheet versions, and every copy is another place an error can hide.
The third is eligibility and timing. Tenure rules, mid-year role changes, and prorated periods are exactly the cases manual spreadsheets get wrong, because they require judgment applied consistently across every employee, every time.
Nearly every company needs custom merit formula logic. What varies is how deep it goes.
The common thread is the comp administrator who values the flexibility of a spreadsheet but is worn down by its manual work, its errors, and its endless version tracking.
Whatever your comp strategy looks like, software built to handle custom compensation formulas should be able to support it, from a basic merit matrix to a multi-condition bonus. If it can’t, keep looking. The table below outlines real scenarios, ordered from the simplest to the most layered, you could use to assess whether a software vendor can truly handle the level of customization you might require. You can use it to ask them to show you how the software would handle certain scenarios.
A custom setup can sound like a heavy lift. It doesn’t have to be, but it is dependent on the compensation software partner you choose.
At Comprehensive, for example, our hands-on implementation team builds your formulas and your full cycle setup for you. Setup averages about a month, and the fastest customers have gone live in two days. The pace is set by how quickly you decide what you want, not by how long the build takes. And because you work in the same account and the same tools the team uses, you are never waiting on anyone to make a change for you.

What is a custom compensation formula? A custom compensation formula is configurable logic that calculates an employee's raise or bonus from a company's own rules (e.g., performance ratings, compa-ratio, bonus targets, multipliers, weighted goals, eligibility, and proration). It lets compensation software run a company's exact pay strategy rather than a fixed, built-in calculation.
Can Comprehensive compensation software handle custom raise and bonus formulas? Yes. Compensation software with a formula engine can model both raise and bonus logic, from a simple performance-rating increase to a multi-factor bonus with company and individual multipliers. The same engine runs salary and bonus, so both cycles happen in one system instead of one in software and one in a spreadsheet.
Can Comprehensive software replicate a merit matrix (performance rating × compa-ratio)? Yes. A merit matrix that combines performance rating and compa-ratio is standard logic. You configure the matrix cells to your own percentages, and the software applies the right increase based on each employee's rating and compa-ratio during the review cycle.
Can salary formulas vary by country or department in the Comprehensive compensation platform? Yes. A merit matrix or increase rule can be set to differ by country or department, so the same rating and compa-ratio can produce different suggested increases in different locations. This handles cases where, for example, a U.S. team and an India team are on separate matrices.
Can Comprehensive compensation software handle complex bonus programs? Yes. Bonus programs with company multipliers, individual multipliers, multiple weighted goals, level-based weighting, eligibility rules, and mid-year proration can all be modeled as formulas. This is the logic that most often keeps bonus cycles stuck in spreadsheets, and it is exactly what the Comprehensive formula engine is built to run.
What's the difference between a company multiplier and an individual multiplier? A company multiplier adjusts a bonus based on overall company performance against a goal, applied to everyone. An individual multiplier adjusts it based on a single employee's performance. Many bonus plans use both: a target is multiplied by the company multiplier and the individual multiplier to reach the final award.
Can Comprehensive handle weighted bonus goals that differ by level? Yes. Goals can carry different weights, and those weights can change by employee level. For example, you could have a VP weighted more heavily toward one goal than an individual contributor. The formula applies the correct weighting per level automatically, rather than requiring a separate calculation for each group.
How does Comprehensive handle mid-year role changes and proration? When an employee changes roles partway through the year, the formula splits the period in two (the time before the change and the time after), applies the right target to each, and sums them into a single prorated result. Rounding rules can be applied on top, so the final number is consistent.
Can AI within Comprehensive build a compensation formula from our spreadsheet? Yes. Our AI can read an existing compensation spreadsheet, build the equivalent formula inside the software, and explain in plain language what the logic does. This lets a company carry over comp logic it already uses without rebuilding it by hand, and makes complex or inherited formulas easier to understand and audit.
Do we have to build the formula logic ourselves within the Comprehensive platform? No. A hands-on implementation team builds the formula logic for you, and you can adjust it yourself at any time. You are never dependent on us to make a change, but you also do not have to construct complex logic on your own if you would rather the Comprehensive team handle it.
Can we run salary and bonus cycles in the same software using Comprehensive? Yes. Salary and bonus run on the same formula engine, so both cycles happen in one platform. This is what lets a company stop running salary logic in software while keeping bonus logic in a spreadsheet. Both live in the same system, with the same data and review process.
