How to Calculate Percentage Increase Step-by-Step
A clear, step-by-step guide to calculating percentage increase manually or with a calculator. Master the formula in minutes.
Determine the exact percentage of your salary raise. Perfect for annual reviews, job offers, and hourly wage adjustments.
Calculate Your Pay Raise Percentage & New Salary
A salary increase percentage is calculated by dividing the difference between your new salary and old salary by your old salary, then multiplying by 100. This calculation creates a standardized metric to verify if your pay raise beats inflation. This salary increase calculator automates the math for annual salaries, hourly wages, and complex pay adjustments instantly.

Raise Formula:
Raise Percentage = ((New Salary − Current Salary) ÷ Current Salary) × 100A salary increase percentage is the standardized metric used to measure pay growth across different jobs and timeframes. Whether you are using a pay raise calculator for an annual review or a new job offer, knowing the exact percentage helps you benchmark your income against inflation.
The salary increase formula is simple: subtract your old salary from your new salary, then divide the result by your old salary. This basic equation powers every calculate salary increase tool on the web.
((New Salary − Old Salary) ÷ Old Salary) × 100
Imagine you are earning $55,000 a year, and your employer offers you a raise to $58,300. You want to calculate salary raise effectiveness.
Step 1: Find the difference (Raise Amount)
$58,300 − $55,000 = $3,300
Step 2: Divide by original salary
$3,300 ÷ $55,000 = 0.06
Step 3: Convert to percentage
0.06 × 100 = 6%
Verdict: A 6% raise is generally solid. It implies your salary increase vs inflation ratio is positive.
Hourly and annual salary increases follow the exact same mathematical principle. To determine your hourly wage increase percentage, simply use your hourly rate in place of annual salary. This salary increase calculator works for any duration—weekly, monthly, or yearly—as long as you compare the same time units.
When evaluating a salary increase after promotion, the percentage is often higher than standard annual raises.
A good salary increase usually starts at 2-4%. These raises are designed to keep up with inflation so your purchasing power stays the same.
Merit increases typically range from 3-7%. These are awarded for good performance, completing projects, or gaining new skills.
Promotions often come with 10-20% raises. This reflects significantly increased responsibilities and often a title change.
Changing companies is frequently the fastest way to increase your base salary significantly, often yielding 15-25% bumps.

The upward trajectory of the blue line represents compound interest working on your salary. Unlike a flat line which would indicate stagnant pay, the curve shows that maintaining this specific growth rate results in exponential rather than linear income expansion over time.
The widening gap between year markers illustrates the accelerating effect of percentage-based raises. As your base salary grows, the same percentage increase is calculated on a larger principal amount, resulting in larger absolute dollar gains each subsequent year.
If the slope of the projected growth line is steeper than the average historical inflation rate (typically 2-3%), your purchasing power is increasing. A curve that sits below the inflation threshold would indicate that your real income is effectively shrinking despite the nominal increase.
A lower Raise Percentage would flatten the slope of the growth curve noticeably. The final Year 5 value would be significantly lower because the compounding effect is highly sensitive to the rate changes; even a 1% difference accumulates into a major divergence over time.
The chart explicitly projects the "potential value" assuming this specific growth rate continues annually. It models a scenario where you receive the same percentage increase every single year, rather than a one-time adjustment.
The first data point labeled "Now" corresponds exactly to your "New Salary" input. This serves as the geometric baseline for all future projections, meaning any error in the initial entry will mathematically skew the entire 5-year forecast.
The final data point at Year 5 indicates your potential future annual salary, not the sum of all years. To understand the total cumulative earnings, one would need to sum the area under the curve or add each individual yearly value displayed on the data points.
The smooth line represents a simplified continuous growth model for visualization purposes. In reality, salary increases are typically discrete events (step-functions) happening once a year, but the curve helps visualize the overall momentum and direction of your earning power.
A one-time bonus would shift the entire curve upward vertically for a single year but would not change the slope of the line. The current growth projection assumes a base salary adjustment which permanently alters the trajectory of all future earnings.
The shape is determined by the exponential growth formula P(1 + r)^t. Because the time variable (t) is an exponent, the salary (P) increases by a multiplying factor rather than a structured addition, creating the characteristic "hockey stick" curve.
A higher "Current Salary" input shifts the entire curve higher on the Y-axis but does not change the steepness of the percentage curve itself. However, the absolute dollar difference between Year 1 and Year 5 would be larger due to the larger principal amount being compounded.
This chart shows a "best-case consistent scenario" where the growth rate implies stability. If future raises fluctuate, the actual real-world line would be jagged and irregular, likely falling below this idealized exponential projection.
A steeper positive slope correlates directly with accelerated wealth accumulation. The sharper the angle of ascent, the significantly shorter the timeframe required to double your income compared to a shallower, more linear progression.
A flat horizontal line would indicate a 0% growth rate, meaning your nominal salary remains exactly the same for 5 years. In real economic terms, due to inflation, a flat visual line actually represents a declining curve in purchasing power.
The Year 5 figure is a mathematical projection, not a prediction. It strictly calculates the result of the explicit mathematical logic (Current × (1 + Rate)^5) and does not account for external economic factors, career interruptions, or variable performance bonuses.
To calculate salary increase, subtract your old salary from your new salary. Next, divide that difference by your old salary. Finally, multiply by 100 to get the percentage. The salary increase formula is: ((New - Old) / Old) * 100.
A 4% salary increase is generally considered a standard cost-of-living adjustment (COLA). It typically matches or slightly exceeds average historical inflation rates. However, for a merit increase or promotion, a good raise is often 10% or higher.
Yes, this tool functions as an hourly wage increase calculator. Simply enter your old hourly rate (e.g., $20) and your new hourly rate (e.g., $22) to see your hourly wage increase percentage. The math is identical to annual salary calculations.
