Three ways I sanity-check long-run salary trajectories before I jump: the pay band map, the two-hop move, and the comp-math trap.
Build a pay-band map before you fall in love with the role

I used to treat industry switching like a one-time salary negotiation problem. Then I watched a friend take a slightly smaller offer into a company with real levels and clean promotion rails, and four years later they were so far ahead it wasn't even a conversation. The difference wasn't charm in the offer stage. It was the ladder they stepped onto.
So now, before I get attached to the mission, I map the pay bands like I'm planning a road trip. I want to know what the next three titles cost and pay, not just the one I'm interviewing for. The fastest way to do this without pretending you have inside access is to triangulate.
- First pass: Pull the job family's compensation range from any transparent posting you can find (some states force ranges). If they only give a wide range, note it anyway.
- Second pass: Cross-check with Levels.fyi for tech roles, or the Radford survey if you can get it through a friend at a bigger company. For non-tech, I lean on Robert Half guides and a couple niche recruiter reports, but I treat them as fuzzy.
- Third pass: Ask one blunt question in a recruiter screen: "What's the typical time-in-level before someone is considered for the next title?" You won't always get a clean answer, but even a dodge is data.
Then I write down the part most people skip: where the ceiling is. Some industries have a wide middle and a skinny top. Others have a fat top if you can get into revenue ownership or regulated expertise. You don't need a perfect forecast, but you do need to see whether you're hopping onto a ladder with six rungs or two. When your long-term earning power is the whole point, the number of rungs matters more than the paint color on the current one.
The two-hop move: pick the industry, then pick the company

When people tell me they want to switch industries for money, they usually mean they want a bigger number now. Fair. But for long-term salary trajectories, the move that changes everything is often a two-hop, not a heroic leap.
Hop one is getting into the right compensation ecosystem. Hop two is upgrading into the part of that ecosystem where comp keeps scaling. If you try to do both at once, you tend to optimize for whoever says yes first. That can strand you in a corner of the new field that has the same old ceiling, just with shinier job titles.
Here's what the two-hop looks like in practice. Say you're coming from an industry where management pay compresses fast and raises top out at inflation-plus. You target an industry that pays for scope, not tenure. You take a role that fits your transferable skills and gets you close to a revenue line or a high-leverage function. You don't need your forever company yet. You need the stamp that says you can operate inside that industry's tooling and tempo: Salesforce hygiene, a modern ERP like NetSuite, a BI layer like Looker, Jira rituals, whatever the place runs on.
Then you watch for the second hop trigger. It might be the moment you can credibly claim a number that carries across employers, like managing a $3M book, owning a pipeline stage, cutting cloud spend with a FinOps program, or leading an implementation with a real go-live. That's when you move to a company with a stronger leveling system, better equity refreshes, or simply a market position that pays for retention.
To keep myself honest, I put a date on it. If the first-hop role doesn't give me a measurable credential within 12 to 18 months, I start interviewing. Not because I'm restless, but because trajectories drift. The goal is not to "break in" and get comfortable. It's to break in and then climb where the rungs get taller.
The comp-math trap: when a promotion beats a switch (on paper)

I've watched people stay for the internal promotion because the spreadsheet looked clean: guaranteed bump, no interview grind, no risk. Then two years later, they're doing bigger work for a pay structure that can't follow. The trick is that compensation isn't one number. It's base, bonus, equity (if any), and the rulebook behind all three.
When I'm choosing between an internal step up and a switch, I do one annoying but clarifying exercise: I model the next 36 months with the rules that typically apply, not the happy path I want to believe. That means I write down assumptions like:
- Base growth: merit range plus promo bump. Some companies do 2% to 4% merit and 8% to 12% promo. Others do tiny merit and a "catch up later" promise that never shows up.
- Bonus reality: target vs paid. If targets are 15% but payouts cluster at 60% of target, I use the cluster, not the brochure.
- Equity mechanics: if the new industry uses RSUs, I note vesting schedules and refresh norms. A one-time new-hire grant feels good until you realize refreshes are what make year three and four comp stop flattening.
- Compression risk: if the company has to hire above you to fill seats, your internal promo might put you right under the new hire band. That gap can stay for years.
None of this requires secret info. You can often get the promo raise policy from HR docs. You can ask a manager, casually, what the last two cycles looked like. You can also spot compression in plain sight when job postings for your level are above your current pay.
And yes, sometimes the promotion wins. If you're moving into a role with genuine scope expansion and the company has a habit of fixing comp to match it, staying can be the smarter play. But when the rulebook is stingy, a conventional promotion can be the prettiest version of standing still. The math exposes it fast, and it keeps you from mistaking a new title for a new trajectory.
