Salary Bands by Experience: The 7-Year Doubling Rule
Last updated · Career Growth · Methodology
Most workers underestimate how much their salary should grow over their career. They accept the standard 3 percent annual cost-of-living adjustment and watch their purchasing power slowly erode while their actual market value grows much faster. The healthy career growth curve is closer to 5–8 percent annually for the first 10 years, with periodic 15–25 percent jumps from job changes or promotions. Over a typical career, this should produce roughly a 2x salary increase every 7 years. This guide explains where this number comes from, what it looks like for major professions, and when to push harder than the default.
The 7-year doubling rule
If your salary grows by 10 percent per year compounded, it doubles in approximately 7 years. The math comes from the rule of 72: divide 72 by the annual growth rate to get the doubling time. 72 / 10 = 7.2 years.
Healthy career growth in the first 10–15 years should be in this range — 8 to 12 percent annually compounded, including both within-company raises and job-change jumps. Below 5 percent, you are losing real purchasing power to inflation and falling behind market rates. Above 15 percent, you are either in an explosive career stage (early career, hot field) or actively job-hopping.
The 7-year doubling rule does not continue forever. After about 15 years, growth typically slows because:
- You hit the natural ceiling for your role and location
- Promotion to management requires different skills and may not be your path
- Your role's market value compresses as you become more specialized
Late-career growth is often 2–4 percent annually with periodic jumps for major moves.
Typical salary curves by profession
Approximate median salary trajectories for major US professions, single-city averages (varies by metro):
Software engineer (US national):
- Entry (0-2 years): $90,000
- Mid (3-6 years): $130,000
- Senior (7-10 years): $175,000
- Staff (11-15 years): $220,000
- Principal (15+ years): $280,000+
This is a near-perfect 7-year doubling for the first 14 years, then flattening. SF Bay Area numbers run roughly 25 percent higher; tier-2 cities run 20–30 percent lower.
Registered nurse:
- Entry (0-2): $68,000
- Mid (3-7): $82,000
- Senior (8-15): $95,000
- Specialty/charge (15+): $115,000
RN compensation grows more slowly than tech, with ceiling effects after about 10 years. Specialty certifications (CRNA, Nurse Practitioner) reset the curve upward dramatically — CRNAs commonly earn $200,000+.
Teacher (public school, US median):
- Entry: $48,000
- 5 years: $55,000
- 10 years: $63,000
- 20 years (top of step): $75,000
Teaching pay scales are usually fixed by district step-and-lane schedules, producing slow predictable growth with little upside. Total comp curves can flatten earlier than nominal salary curves due to retirement contribution changes.
Marketing manager:
- Entry coordinator: $52,000
- Specialist (3-5): $68,000
- Manager (6-10): $90,000
- Senior manager (10-15): $115,000
- Director (15+): $145,000+
Job change vs stay: the math
The single largest determinant of whether you achieve the 7-year doubling is how often you change jobs. Employees who stay at one company for 2+ years between salary reviews tend to receive 3–5 percent annual raises, well below market growth. Employees who change companies every 2–4 years tend to negotiate 10–20 percent raises with each move, far above the within-company rate.
The "loyalty tax" is real and well-documented. ADP's Pay Insights report consistently shows job changers earning 5–8 percent higher annual increases than job stayers in the same role and location. Over a 10-year career, that compounds to a 50–80 percent salary gap between two otherwise-identical employees.
This does not mean changing jobs every year. Two to three years per company is the sweet spot — long enough to build real accomplishments and references, short enough to capture market premiums during job changes. Frequent job hopping (under 18 months) starts to look like a red flag and reduces your bargaining position.
When to push for above-market raises
Three situations where you should ask for more than the standard 3–5 percent annual:
- You took on materially more responsibility — managing more people, owning a larger budget, leading a critical project. The market price for your role has changed, and the company should match it.
- Market rates have moved — when your industry sees a labor shortage or inflation spikes, the market median for your role rises. You should match it.
- You have a competing offer — the most powerful negotiating tool. A real offer letter from a credible competitor proves your market value and gives the current employer a clear ask.

When growth slows: the late-career ceiling
Most professions show diminishing returns after 15–20 years. The reasons:
- Specialization narrows your market. Becoming a deep expert in one tool or method makes you more valuable to fewer companies. Your bargaining position narrows.
- Managerial roles require different skills. The promotion path to higher pay often runs through people management, which not everyone wants or excels at.
- Age discrimination is real in some industries (especially tech), making new job offers harder to obtain past age 50.
Strategies for late-career growth:
- Move into management or principal-level technical roles with measurable leadership impact
- Consult or freelance at higher hourly rates than full-time employment
- Switch to a lower-cost-of-living area to maintain real income with smaller nominal raises
- Build equity ownership through stock-heavy employers, founder roles, or rental property income
Frequently Asked Questions
How fast should my salary grow each year?+
Healthy growth is 5–8 percent annually for the first 10–15 years of your career, including both within-company raises and job-change jumps. Below 5 percent means you are losing ground to inflation and market rates. Above 12 percent typically requires job changes or promotions.
What is the 7-year doubling rule?+
A heuristic that healthy salary growth (about 10 percent per year compounded) doubles your salary in approximately 7 years. Comes from the rule of 72: 72 ÷ growth rate = doubling time. Useful as a benchmark for whether your career trajectory is on track.
Should I change jobs to get a raise?+
Often yes. ADP data shows job changers earn 5–8 percent more in raises than job stayers, year after year. Two to three years per company is the sweet spot — long enough to build accomplishments, short enough to capture market premiums. Avoid job-hopping under 18 months, which starts to look like a red flag.
How much should I ask for in a raise?+
Standard cost-of-living: 3–5 percent. After taking on more responsibility: 8–15 percent. After receiving a competing offer: match or exceed the offer. Always anchor your request in market data (BLS percentiles for your role and location).
When does salary growth typically stop?+
Most professions see growth slow after 15–20 years as specialization narrows your market and managerial roles become the only path to higher pay. Late-career growth is typically 2–4 percent annually with occasional jumps for major moves, retirement-job transitions, or consulting.
How do I know if I am underpaid?+
Look up median salary for your role in your metro on BLS or our occupation pages. If your salary is more than 15 percent below median and you are at or above the typical experience level for that median, you are likely underpaid. Use the gap as a negotiation anchor.
