Minimum Wage Increase Calculator: Percentage Change Between Two Wages
Work out the percentage increase between an old and new minimum wage — and the hourly and annual dollar difference — useful for understanding wage-law changes as a worker, or labor-cost impact as an employer.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Wage increase | Hourly increase |
|---|---|---|
| $7.25 to $15 (+106.9%) | 106.90% | 7.75 |
| $12 to $15 (+25%) | 25.00% | 3 |
| $15 to $16.50 (+10%) | 10.00% | 1.5 |
| $10 to $11 (+10%) | 10.00% | 1 |
How This Calculator Works
Enter the old hourly wage and the new hourly wage. The calculator finds the percentage increase and the hourly dollar difference. To estimate the annual impact, multiply the hourly increase by the hours worked per year (full-time is about 2,080 hours).
The Formula
Percentage Change
Old is the starting value, New is the ending value
Worked Example
Going from $7.25 to $15 an hour is a 106.9% increase — $7.75 more an hour. For a full-time worker (2,080 hours/year), that's about $16,120 more in annual gross pay. For employers, the same change roughly doubles the wage cost of minimum-wage staff, which is why minimum-wage debates weigh higher worker incomes against employer cost pressures, potential price increases, and effects on hiring — economists disagree on the magnitude of each.
Key Insight
Minimum-wage changes are a percentage-change calculation with outsized real-world stakes on both sides. For workers, the headline is the raise in take-home pay, but the real value depends on local cost of living and whether prices rise in response — a wage increase that's matched by higher local prices delivers less than the percentage suggests. For employers, a minimum-wage hike raises labor cost directly for affected staff and can ripple upward (workers earning just above the old minimum often expect raises too), prompting responses like price increases, reduced hours, automation, or slower hiring. The economic evidence is genuinely mixed: studies find modest increases often raise incomes with limited employment loss, while very large or rapid increases carry more risk — context (local wage levels, industry, speed of the increase) matters enormously. This calculator gives the clean arithmetic: the percentage jump and the per-hour and annual dollar change. Use it to ground the discussion in concrete numbers, then layer in cost-of-living, ripple effects, and the specific labor market for the full picture.
Why federal minimum hasn't risen since 2009
Federal minimum stuck at $7.25 since 2009. Lost ~30% real value to inflation through 2024.
Political reasons. Substantial opposition to increase. Concerns about employment effects, small business impact, regional cost-of-living differences.
State action. 30+ states have minimums above federal. Many indexed to inflation (CA, NY, WA, OR, etc.) — automatic annual increases.
City action. Some cities substantially above state minimum. Seattle $20.76 starting 2025; San Francisco area $18-$21 depending on company size; NYC $16.00.
Recent trend. Substantial state and local minimum wage increases. Federal proposals to raise to $15-$17 introduced multiple times; not passed.
Strategic implication for businesses. Multi-state employers face substantially different minimums by location. Must comply with each. Substantial wage cost variation across markets.
Economic effects of minimum wage increases
Empirical research mixed. Some studies show substantial employment effects (job loss); others show negligible effects.
Most rigorous research (Card-Krueger 1994 New Jersey study, subsequent replications). Found minimal employment effects from moderate minimum wage increases.
Mechanisms. (1) WAGE COMPRESSION — small effects on near-minimum workers. (2) REDUCED HOURS — instead of layoffs. (3) PRICE INCREASES — passed to consumers. (4) PRODUCTIVITY GAINS — businesses invest in efficiency.
Substantial increases (50%+ over short period) may show larger effects. Gradual increases (5-10% annually) consistent with current research.
Strategy for businesses. (1) AUTOMATE WHERE POSSIBLE. Self-checkout, mobile ordering reduce labor needs.
(2) RETAIN EMPLOYEES. Higher minimum makes retention more valuable.
(3) PRICE STRATEGICALLY. Pass through some labor cost increases.
(4) PRODUCTIVITY INVESTMENT. Train workers; improve processes.
Workers' interests. Substantial minimum wage increases improve substantial worker incomes. Substantial population earning at or near minimum receives meaningful pay increase.

Reference U.S. minimum wages.
| Jurisdiction | 2024 minimum wage |
|---|---|
| Federal | $7.25 (unchanged since 2009) |
| California | $16.00 |
| Washington | $16.28 |
| New York (downstate including NYC) | $16.00 |

| New Jersey | $15.13 |
| Illinois | $14.00 |
| Maryland | $15.00 |

| Texas | $7.25 (federal) |
| Georgia | $7.25 (federal) |
| Tennessee | $7.25 (federal) |
| Seattle (city) | $19.97 (rising to $20.76 in 2025) |
| San Francisco (city) | $18.67 |
Substantial geographic variation in U.S. minimum wages. Coastal states substantially above federal. Southern states largely federal-only. Cities often above state minimums. Multi-state employers face complex compliance. For specific industry, verify state and local minimums.
Frequently Asked Questions
How is the minimum wage increase calculated?
Subtract the old wage from the new wage, divide by the old wage, and multiply by 100. From $7.25 to $15 is ($15 − $7.25) / $7.25 = 106.9%, an increase of $7.75 an hour.
What's the annual impact of a wage increase?
Multiply the hourly increase by annual hours worked. At full-time (about 2,080 hours/year), a $7.75/hour increase is roughly $16,120 more in gross annual pay. Part-time workers see a proportionally smaller annual change based on their hours.
How does a minimum wage increase affect employers?
It raises labor cost directly for minimum-wage staff and often ripples upward, since workers earning just above the old minimum may expect raises too. Employers may respond with price increases, reduced hours, automation, or slower hiring — the magnitude depends on the industry and the size of the increase.
Does a higher minimum wage mean more real income?
Usually, but not by the full percentage. If local prices rise in response, or if the worker's hours are cut, the real gain is smaller than the headline increase. Cost of living and any price effects determine how much the raise actually improves purchasing power.
What does the research say about minimum wage increases?
It's mixed and context-dependent. Studies often find modest increases raise incomes with limited employment loss, while very large or rapid increases carry more risk to jobs and hours. Local wage levels, industry, and the speed of the increase all matter, which is why economists debate the effects.
When is this calculator unreliable?
When applying federal minimum to states with higher minimums (must use higher). Also unreliable for tipped employees (separate tipped minimum substantially lower in many states). For accurate compliance, verify state, city, and tipped-employee minimums applicable to specific situation.

Methodology & Review
Minimum wage increase equals (new minimum wage − old minimum wage) / old minimum wage × 100. The calculator returns increase percentage. U.S. federal minimum wage 2024 $7.25 (unchanged since 2009). State minimums vary substantially: California $16.00; Washington $16.28; New York $16.00 (NYC and other downstate); Florida $13.00 rising. Tipped minimum varies separately. RELIABILITY: Reliable for documented rates. Less reliable when (a) federal vs state minimums differ (must use higher); (b) tipped minimum substantially different in many states.
