Most women in STEM do not wake up one day and realize they are underpaid. It happens gradually, quietly, and often invisibly. You accept the first offer because you are grateful for the opportunity. You receive modest annual raises that feel reasonable in isolation. You tell yourself that things will improve with time, with the next performance review, with the next role. And before you know it, years have passed and the gap between what you earn and what the market pays for your skills has widened into something that will take real effort to close.
Being underpaid is not just a numbers problem. It is a compounding one. Every year the gap persists, it grows. Every raise and bonus calculates from a lower base. Every promotion carries the shadow of a salary that was never correctly set. The earlier you recognise the signs and take action, the less it costs you in the long run. This article gives you both.
Why Women in STEM Are Particularly Vulnerable
Before getting into the signs, it helps to understand why underpayment is so common among women in STEM specifically.
Research consistently shows that women in technical fields earn less than male peers at equivalent levels, with gaps ranging from 10% to 25% depending on the sector, seniority, and geography. For women of colour in STEM, that gap is wider at every level. Several factors drive this:
- First offer acceptance: Women in STEM are more likely to accept an initial salary offer without negotiating, while men are more likely to counter. Organisations know this and sometimes exploit it.
- Reluctance to self-advocate: The cultural conditioning that makes many women in STEM feel uncomfortable claiming their value directly means they are less likely to ask for raises proactively.
- Invisible benchmarking: Many women do not know what peers at their level actually earn because salary conversations feel taboo, which means they have no reference point to assess their own compensation accurately.
- The broken rung effect: Women who miss the first promotion to manager carry a lower salary baseline into every subsequent role. Every raise and bonus then calculates from a lower starting point, compounding the gap over time.
Understanding this context matters because it removes the personal blame from a structural problem. Being underpaid is not a reflection of your worth or your performance. It is often the predictable outcome of systems that were not designed to pay women fairly without active pressure to do so.
Signs You Are Being Underpaid
1. You Have Never Negotiated Your Salary
If you accepted your current salary at face value without countering, there is a reasonable chance you left money on the table. Most initial offers in STEM roles have negotiation room built in. Organisations expect some candidates to push back. If you did not, your starting point was likely lower than it needed to be, and every subsequent raise has calculated from that lower base.
2. Your Salary Has Not Kept Pace With Your Skills
Your skills, expertise, and responsibility have grown significantly since you joined your organisation. Your salary has received modest annual increases that have not reflected that growth. This is one of the most common forms of underpayment in STEM careers. The market values your current skills significantly more than your original hiring salary accounted for, but your organisation has not adjusted to reflect that reality.
3. You Took Time Out and Came Back at a Lower Rate
Career breaks for caregiving, health, further education, or other reasons often result in women re-entering the workforce at rates that do not account for the experience they had before the break. If you returned to a role at a salary similar to or below what you earned before your break, without any adjustment for the years of expertise you brought back with you, you are likely underpaid relative to your actual market value.
4. You Recently Discovered What a Colleague Earns
Salary conversations at work feel uncomfortable, but when they happen, they are often revealing. If you have learned, through a direct conversation, a job posting, or a salary survey, that a colleague at a similar level with similar experience earns meaningfully more than you do, that is a signal worth taking seriously. One data point is not definitive, but it is a starting point for a broader benchmark.
5. Your Job Posting Advertises a Higher Range Than You Earn
If your organisation or a competitor is currently advertising your role or a comparable one at a salary range that exceeds what you currently earn, that is a clear market signal. Job postings reflect what organisations are currently willing to pay for the skills your role requires. If the market rate has moved significantly above your current salary, you have grounds for a conversation.
6. You Have Been Promoted Without a Meaningful Pay Increase
Promotions in STEM environments sometimes come with title changes and expanded responsibilities but without salary adjustments that reflect the new level of contribution. If your title changed but your pay did not move proportionally, you may be doing senior work at a junior salary. This is a specific and common form of underpayment that compounds quickly when your next review bases your raise on the same understated figure.
7. Your High Performance Has Not Translated Into Higher Pay
Consistent high performance ratings that are not accompanied by meaningful salary progression are a warning sign. Research shows that women in STEM are consistently rated as strong performers and simultaneously passed over for the financial rewards that performance should produce. If you have received excellent reviews year after year without corresponding pay movement, the problem is not your performance. It is the system.
8. You Feel Uncomfortable Asking What You Are Worth
This one is less about the numbers and more about the mindset that often surrounds them. If you feel anxious, guilty, or somehow arrogant when you consider asking for more money, that discomfort is itself worth examining. It is often the residue of cultural conditioning that tells women their needs should come second, that asking for more is greedy, and that gratitude for employment should override the drive for fair compensation. That conditioning is expensive. It keeps women quiet in the exact moments when speaking up would make the most difference.
What to Do About It
Step 1: Benchmark Your Market Value
Before any conversation about salary, you need accurate external data. Use multiple sources to build a clear picture of what the market currently pays for your skills, your level, and your sector.
Useful benchmarking resources:
- LinkedIn Salary
- Glassdoor and Levels.fyi for technical roles
- Industry-specific salary surveys from professional associations
- Government labour statistics for your field
- Salary transparency communities and forums specific to your industry
Use at least three sources and look at ranges rather than single figures. Note the median, the 75th percentile, and any factors that might move you toward the higher end, such as specialised certifications, leadership experience, or rare technical skills.
Step 2: Calculate the Full Cost of the Gap
Once you have a benchmark, calculate what the gap is actually costing you. Take the difference between your current salary and the market median or the salary you believe you should be earning. Multiply that figure by the number of years you have been underpaid. Then factor in compound growth on the lost income if it had been invested.
As explored in our piece on Million Dollar Mistakes: The Hidden Math Behind Career Stagnation, a gap that feels manageable on an annual basis often reveals itself as a six or seven-figure lifetime loss when the compounding is calculated. Write that number down. Put it somewhere visible. Let it motivate the conversation you have been putting off.
Step 3: Document Your Impact in the Language of Business
A salary negotiation grounded in your feelings about fairness is less effective than one grounded in evidence of business impact. Before you have any compensation conversation, build a specific, evidence-based case that connects your contributions directly to outcomes the organisation cares about.
This means quantifying wherever possible. Not “I led the project” but “I led the initiative that reduced processing time by 35%, saving the department an estimated 400 hours per quarter.” Not “I manage a team” but “I manage a team of eight engineers whose combined output increased by 20% under my leadership.”
The three pillars of visibility and positioning explored in The 3 Pillars of Career Advancement: Visibility, Sponsorship, Positioning apply directly here. Before you can negotiate effectively, the right people need to have a clear, accurate, and compelling picture of your impact. Build that picture deliberately before you make your ask.
Step 4: Have the Conversation Directly and Confidently
Once you have your benchmarks and your impact evidence, request a dedicated conversation with your manager specifically about compensation. Do not attach this conversation to a performance review if you can avoid it. Make it a standalone meeting with a clear purpose.
In the meeting, lead with your research, not your feelings. “Based on my research into current market rates for this role and level, and the specific contributions I have made over the past year, I would like to discuss bringing my compensation in line with the market.” Follow with your impact evidence. State the number you are asking for. Then stop talking.
Most people fill the silence that follows a salary request with qualifications and backtracking. Do not. State your ask clearly and let the other person respond before you say anything else. The discomfort of that silence is part of the process. Stay in it.
Step 5: Be Ready to Escalate If the Answer Is No
If your direct manager cannot or will not address the gap, you have options. You can escalate to HR with your benchmarking data. You can seek out a sponsor who can advocate for your compensation in rooms you are not in. You can begin exploring external offers, which often produce movement on internal compensation faster than any other strategy. And if the organisation consistently undervalues your contribution despite clear evidence and direct advocacy, you can decide that your market value is better honoured somewhere else.
Frequently Asked Questions
How do I find out what colleagues earn without making things awkward?
Salary surveys, industry reports, and job postings are your starting points. Some professional communities and networks also share salary information openly. If a trusted colleague is willing to share directly, that conversation is protected and valuable. You are also legally protected in most countries from retaliation for discussing your salary with colleagues.
What if my manager says the budget does not allow for an increase?
Ask what would need to change for a salary review to be possible and when that conversation could be revisited. Ask about non-salary compensation such as bonuses, additional leave, or professional development funding. And begin building your case for an external offer in parallel.
Is it too late to address underpayment if I have been in my role for several years?
It is never too late, but the longer you wait, the more the gap compounds. A salary correction conversation is harder the longer the underpayment has gone unaddressed, but it is always worth having. The alternative is continuing to pay the cost indefinitely.
Should I reveal a competing offer to get a raise?
A competing offer is one of the most effective leverage points in a salary negotiation, but use it only if you are genuinely prepared to accept the other offer if your current employer does not respond. An offer you are not willing to take is a weak negotiating position if it is called.
Conclusion
Being underpaid is not a minor inconvenience. It is a compounding financial reality that grows more expensive every year it goes unaddressed. The signs are often visible long before women act on them, not because women do not notice but because the discomfort of advocating for fair pay feels greater than the discomfort of accepting less.
That calculation needs to change. The market will not correct itself on your behalf. Your organisation will not spontaneously offer you what you are worth without being asked. The gap will not close on its own.
Benchmark your value. Calculate the cost. Document your impact. Have the conversation. And refuse to let another year pass paying a price that was never yours to pay.
