Improvement Percentage Calculator

Tracking growth, progress, or performance is essential in many areas of life, from academics and business to fitness and productivity. Often, this involves calculating the percentage improvement between two values.

Our Improvement Percentage Calculator makes it simple to determine exactly how much something has improved over time, providing instant, accurate results without manual calculation.


🔎 What is Percentage Improvement?

Percentage improvement is a way of expressing the change between an original value and a new value as a percentage. It answers the question:

“By what percentage has something improved?”

The formula is: Improvement (%)=New Value−Original ValueOriginal Value×100\text{Improvement (\%)} = \frac{\text{New Value} – \text{Original Value}}{\text{Original Value}} \times 100Improvement (%)=Original ValueNew Value−Original Value​×100

Where:

  • New Value = the latest or improved measurement
  • Original Value = the initial measurement

🧮 How to Use the Improvement Percentage Calculator

  1. Enter the original value – This is your starting point.
  2. Enter the new value – This is the improved or current measurement.
  3. Click Calculate – The calculator instantly shows the improvement percentage.
  4. Optional: Reset – Clear the values to calculate again for different data.

📌 Practical Examples

Example 1 – Academic Score

A student scored 70% on a test and later scored 85%. Improvement (%)=85−7070×100=1570×100≈21.43%\text{Improvement (\%)} = \frac{85 – 70}{70} \times 100 = \frac{15}{70} \times 100 \approx 21.43\%Improvement (%)=7085−70​×100=7015​×100≈21.43%

So the student’s score improved by 21.43%.


Example 2 – Business Sales

A company’s sales increased from $50,000 to $65,000. Improvement (%)=65,000−50,00050,000×100=30%\text{Improvement (\%)} = \frac{65,000 – 50,000}{50,000} \times 100 = 30\%Improvement (%)=50,00065,000−50,000​×100=30%

This means sales improved by 30%.


Example 3 – Fitness Progress

A runner improved their distance from 5 km to 6.5 km in a week. Improvement (%)=6.5−55×100=30%\text{Improvement (\%)} = \frac{6.5 – 5}{5} \times 100 = 30\%Improvement (%)=56.5−5​×100=30%

The runner’s performance improved by 30%.
