Income Percentile Calculator

Understanding where your income falls in the broader distribution can provide valuable context for career planning, negotiations, and conversations about economic inequality. This income percentile calculator estimates your position within the U.S. individual income distribution based on your annual gross income in U.S. dollars.

The tool is designed for U.S. individual, pre-tax (gross) annual income. It is not intended for household income, after-tax income, or incomes in other countries or currencies. The output is an approximation, not an official government statistic, but it gives a useful snapshot of how your earnings compare to other U.S. earners.

How the calculator works

The calculator uses a simple statistical technique called linear interpolation between key income thresholds. These thresholds come from published percentiles of the U.S. individual income distribution (for example, 10th, 25th, 50th, 75th, 90th percentiles) based on recent national survey data from sources such as the U.S. Census Bureau and related economic research.

Each threshold represents an approximate income level associated with a specific percentile. For example, the median (50th percentile) is the point at which half of earners make less and half make more. Higher percentiles correspond to higher income thresholds.

To estimate your percentile, the calculator finds the two anchor points your income falls between, then assumes that the income distribution between those two points is roughly linear. It then computes a position between those percentiles proportional to how far your income lies between the two incomes.

Formula used (linear interpolation)

Suppose your income is denoted by I. Imagine we have two nearby anchor points in the income distribution:

• I_i with percentile P_i
• I_i+1 with percentile P_i+1

If your income lies between these two anchors, the estimated percentile P_est is computed using linear interpolation. In MathML form, this can be written as:

In plain language, this says: start from the lower percentile P_i, then add a fraction of the gap between P_i and P_i+1. The fraction is how far your income lies between I_i and I_i+1.

If your income is exactly equal to one of the anchor incomes, the calculator simply returns the corresponding percentile for that anchor. If your income is below the lowest anchor or above the highest anchor, the model extrapolates based on the closest available interval, which increases uncertainty but still provides a rough estimate.

Interpreting your income percentile

Your income percentile tells you the percentage of U.S. individual earners whose incomes are below yours. For example, if the calculator estimates that you are at the 70th percentile, that means you earn more than approximately 70% of U.S. individuals, and about 30% earn more than you.

Here are a few ways to interpret different percentile ranges:

• Below the 25th percentile: Your income is lower than most U.S. individual earners. This can reflect early career stages, part-time work, low-wage sectors, or time out of the labor force.
• 25th–50th percentiles: You fall in the lower-middle portion of the income distribution. Many early- to mid-career workers are in this range.
• 50th–75th percentiles: Your income is above the median. This range often corresponds to more specialized roles, mid-to-late career stages, or higher-paying regions or industries.
• Above the 90th percentile: You are among the highest-income individuals. Small income differences at this level can correspond to large differences in percentile rank, especially in very high-earning professions.

Percentiles are relative measures. Being at the 80th percentile does not necessarily mean you feel financially secure or that your cost of living is low. Local prices, housing markets, taxes, family size, and debt can all significantly affect your day-to-day experience.

Worked example

To see the interpolation in action, imagine the model uses the following simplified anchor points (values are illustrative, not exact):

• 50th percentile (median): $55,000
• 75th percentile: $100,000

Suppose your annual gross income is $80,000. This amount falls between $55,000 and $100,000. We want to know where $80,000 lies between the 50th and 75th percentiles.

1. Compute how far your income is above the lower anchor: $80,000 − $55,000 = $25,000.
2. Compute the total income span between anchors: $100,000 − $55,000 = $45,000.
3. Find the fraction of the span your income represents: $25,000 ÷ $45,000 ≈ 0.556.
4. Apply this fraction to the percentile gap: 0.556 × (75 − 50) = 0.556 × 25 ≈ 13.9.
5. Add this to the lower percentile: 50 + 13.9 ≈ 63.9.

In this simplified example, an income of $80,000 would be estimated around the 64th percentile. The actual calculator uses more anchor points across the distribution, which allows for more nuanced estimates across low, middle, and high incomes.

Illustrative anchor income table

The model behind this calculator relies on a set of approximate anchor incomes associated with specific percentiles of the U.S. individual income distribution. The exact values may differ slightly from the table below and may be updated over time, but a simplified version could look like this:

These numbers are rounded and provided for illustration. Real underlying values in the calculator may differ and may be based on a more detailed set of percentiles and incomes, but they follow the same general pattern: higher percentiles correspond to higher income thresholds.

Methodology, assumptions, and limitations

Like any simplified model, this calculator makes assumptions that affect how you should interpret the results. Being aware of these limitations helps you use the tool appropriately.

• Scope: U.S. individual income only. The model is based on distributions of individual incomes in the United States. It does not reflect household income, family income, or income distributions in other countries. If you enter household income or non-U.S. income, the percentile result will not be meaningful.
• Pre-tax (gross) annual income. The intended input is gross income before income taxes and most payroll deductions, aggregated on an annual basis. This can include salary, regular bonuses, and other recurring compensation. If you enter after-tax income, your percentile may be understated relative to other gross-income measures.
• Approximate and rounded thresholds. Anchor incomes are based on publicly available percentile estimates from sources such as the U.S. Census Bureau and economic research organizations. For usability, they are rounded and sometimes smoothed, so they should be treated as ballpark figures rather than exact quantities.
• Static snapshot of a changing distribution. Income distributions change over time due to inflation, wage growth, labor market shifts, and policy changes. The calculator reflects a particular data window and does not automatically adjust for future changes in the distribution or the cost of living. As the data are updated periodically, estimates may shift.
• Linear interpolation between percentiles. Actual income distributions are not perfectly linear between percentiles. By assuming straight lines between anchor points, the model simplifies the underlying shape of the distribution. This works reasonably well for mid-range incomes but is a coarser approximation at the very bottom and very top.
• Extrapolation at extremes. For very low incomes (below the lowest anchor) or very high incomes (above the highest anchor), the model extrapolates beyond the data. These extrapolated percentiles are especially approximate and may not align closely with more detailed studies.
• Sampling and measurement error in source data. The underlying survey data are subject to sampling error, response biases, under-reporting of certain income types, and top-coding (where extremely high incomes are grouped together). These factors introduce further uncertainty into any derived percentile estimates.

Because of these limitations, you should view your percentile result as an estimate with a margin of error, not as a precise measurement. It can still be quite useful for broad comparisons and context but should not be the sole basis for high-stakes financial decisions.

Using your percentile result in practice

Here are a few practical ways to use your estimated income percentile:

• Career and salary discussions: Knowing roughly where you stand can help you gauge whether your earnings are in line with typical outcomes for your field, experience level, and location. Combine this with job-specific market data when negotiating.
• Financial planning: Your percentile can act as a rough reference point when thinking about savings rates, retirement planning, and major expenses, especially when combined with local cost-of-living comparisons.
• Understanding inequality: Percentiles highlight the spread of incomes across the population. They can illustrate how a relatively small group of high earners accounts for a large share of total income.
• Tracking progress over time: If you periodically update your income, you can see whether your percentile is rising, falling, or staying stable. However, remember that the distribution itself can change over time, so comparisons across many years should be made cautiously.

Comparison: this tool vs. other approaches

Different tools use different data sources, definitions, and statistical methods. The table below summarizes how this calculator compares with some common alternatives:

Data sources and updates

The underlying anchor points in this calculator are derived from publicly available summaries of U.S. income distributions from sources such as the U.S. Census Bureau and other reputable economic research organizations. Because official data are typically published with a lag and may be revised, there is no guarantee that the model reflects the very latest figures at every moment.

The intent is to periodically review and update the anchor incomes as new data become available. When updates occur, percentile estimates for the same income may shift slightly, reflecting changes in the overall distribution rather than changes in your individual circumstances.

If you need highly precise or legally significant income comparisons, consult official statistical releases or professional financial and legal advisors. This calculator is best used as a convenient, privacy-preserving way to gain a quick sense of where your income fits within the broader U.S. landscape.
