How Much to Ask for in Salary Negotiation: A Data-Driven Guide

Most people who negotiate salary ask for too little — not too much. A 2023 analysis by the BLS found that workers who negotiated a starting salary secured an average of 5–10% more than the initial offer, yet fewer than 40% of candidates negotiate at all. The risk of asking for a reasonable, market-backed number is almost always lower than the cost of accepting below-market pay you'll carry forward into every future raise.

This guide covers how to calculate a specific number, what anchors to use by experience level, how to adjust for location and total compensation, and what to do if the employer pushes back.


Why your target number must start with market data

Intuition and cost-of-living estimates are a weak foundation for a negotiation target. The number you ask for needs to be defensible — ideally with a source the employer can verify.

Official labour statistics give you that foundation. In the UK, the ONS Annual Survey of Hours and Earnings (ASHE) reports median and percentile earnings by occupation and region. In the US, the BLS Occupational Employment and Wage Statistics (OEWS) programme publishes p25, median, p75, and p90 wages for over 800 occupations. Germany's Destatis earnings structure survey, France's INSEE earnings data, and Statistics Canada's Labour Force Survey provide the same percentile-level granularity for their respective labour markets.

Percentile position is what matters most. The median is the 50th percentile — half of workers in that role earn more, half earn less. If you have four years of experience in a role where five years is typical, you're a median candidate. If you're a top-quartile performer with transferable skills the employer has been struggling to hire, p75 is a reasonable anchor. If you're moving into a new vertical where you'll need three to six months to reach full productivity, p25 to median is realistic.

Before entering any negotiation, benchmark your offer against official government data at CompVerdict. The tool returns a verdict — "Strong offer", "Fair offer", "Slightly below market", and so on — based on ONS, BLS, Destatis, and other official sources, in under 30 seconds.


How much to ask for in salary negotiation by experience level

The number you open with should reflect where you sit in the experience distribution for that specific role, not your seniority across your entire career.

0–2 years of relevant experience: Target p25 to median for the role and location. Opening above p75 without strong differentiating evidence gives the employer an easy reason to walk away.

3–6 years of relevant experience: Median to p75 is the defensible range. If you have a measurable track record — revenue generated, cost savings, team size managed — p75 is a reasonable opening position.

7+ years or specialist skills in short supply: p75 to p90. According to ONS ASHE 2024, the p90 for software developers in London is approximately £95,000 in base salary. For senior data engineers in that market, BLS OEWS data for comparable US metro areas shows p90 wages exceeding $160,000. These figures represent real ceilings for experienced hires, not aspirational outliers.

A practical rule: ask for 10–15% above your actual target. If you want £72,000 and the offer is £65,000, open at £78,000–£80,000. This creates room to concede without dropping below your acceptable floor, and it signals that you've done the research.


Adjusting your number for location and total compensation

Base salary is not the whole picture, but it is the number you negotiate first because it compounds — it affects pension contributions, bonus targets, and future raise baselines.

Location adjustments are significant. According to ONS ASHE 2024, median full-time earnings in London are roughly 25–30% higher than the UK national median across most professional occupations. BLS OEWS 2024 data shows that software developers in San Francisco earn a median around $145,000 compared to roughly $105,000 in mid-sized Midwest cities. The CBS labour accounts for the Netherlands show Amsterdam-region salaries running 10–15% above the national median in knowledge-sector roles.

When the employer quotes a number, check whether it's appropriate for your city, not just the country average.

For equity and bonus, apply a discount before adding them to your total compensation comparison. A 20% target bonus that has paid out at 10% historically is worth 10% in negotiation terms. Unvested equity in a private company at Series B carries real dilution and liquidity risk. Understanding how to evaluate a job offer in full — not just the headline base — will stop you from accepting a below-market salary in exchange for compensation that may never materialise.


How to frame the number when you deliver it

The delivery matters. A number without reasoning is an opening bid. A number with a source is a position.

Structure your ask in three parts:

  1. The number: "Based on current market data for this role in [city], I'm targeting a base salary of £X."
  2. The anchor: "ONS ASHE data puts the median for this role at £Y, and given my background in [specific area], I'm benchmarking against the p75, which is approximately £Z."
  3. The opening: "I'd like to understand whether there's flexibility to reach that range."

This framing does two things. It signals that your number isn't arbitrary, and it invites the employer to respond rather than simply reject. If they cannot reach your number in base, you have a natural transition to discuss signing bonuses, earlier review cycles, or remote working arrangements that reduce your effective cost of living.

Salary counter offer email templates can help you put this in writing after a verbal conversation — a written record prevents the offer from reverting to the original figure.


What to do if the employer says no

A flat refusal is rare when the number is market-grounded. More common responses are:

If the employer cannot reach market rate and will not commit to a timeline for correction, that is a data point about how they value the role. How to negotiate salary after an offer covers the full sequence of responses for each of these scenarios in more detail.

The one scenario where you should pause before pushing further: if CompVerdict or official BLS/ONS data shows the offer is already at p75 or above for your role and location, you have less leverage and more to lose by pressing. Know where you stand before you negotiate.


Frequently asked questions

How much above the offer should I ask for in salary negotiation?

In most cases, 10–15% above your actual target is a reasonable opening. This creates room to negotiate down while landing where you want. If the initial offer is already at or above the market median for your role and city, a smaller ask — 5–8% — is more defensible. Use official percentile data to set the ceiling before you decide how high to open.

Is it better to give a number first or wait for the employer?

Give a number first once you have an offer in hand. Research consistently shows that the first anchor in a negotiation has an outsized influence on the final result. Waiting for the employer to move first only makes sense in early screening conversations before an offer is made — at that stage, deflecting with "I'd like to understand the full role before discussing compensation" is reasonable.

Can I negotiate salary even if the job posting listed a salary range?

Yes. A posted range is a starting position, not a ceiling. Employers typically expect candidates with strong experience to aim for the upper half of the range or slightly above it. If your credentials justify p75 or above for the role, make that case with market data regardless of what the posting said.

What if I don't know my market percentile?

CompVerdict benchmarks your offer against ONS, BLS, Destatis, and other official government data sources by role, experience level, and city. Enter the offer details and you'll get a percentile position and a verdict in under 30 seconds — no account required.


Knowing the right number to ask for removes most of the anxiety from salary negotiation. The calculation is straightforward: find the official percentile for your role and location, identify where your experience sits in that distribution, add 10–15% as your opening position, and back it with a source. Before you make that ask, check your current offer at compverdict.com to confirm whether you're negotiating from a below-market position or fine-tuning an already competitive package. The verdict takes under 30 seconds and gives you the data you need to have the conversation on solid ground.
