Earnings Per Share Growth Calculator
Free online earnings per share growth calculator to measure how fast EPS has grown over time. This calculator is useful for investors, equity analysts, finance students, business owners, and anyone comparing the quality of profit growth across companies. Earnings per share growth is one of the clearest ways to judge whether a business is creating more profit for each share over time. It is especially useful because total net income alone can be misleading when a company issues or repurchases shares. EPS growth focuses on what common shareholders actually receive on a per-share basis, which makes it a practical bridge between profitability trends and stock valuation.
This calculator uses four main inputs. Previous earnings per share means the EPS from the earlier period you want to compare against. Current earnings per share means the most recent EPS figure. Number of years means the full time span between the two EPS values. Current share price means the market price used to add a valuation-style PEG ratio view. Once these values are entered, the calculator shows EPS change, total EPS growth, annualized EPS growth, and PEG ratio. These outputs help you see the raw increase in EPS, the total growth over the period, the average yearly compound pace, and how the stock’s current valuation compares with that growth rate.
The formula of earnings per share growth
EPS change = Current EPS – Previous EPS
Total EPS growth = (Current EPS – Previous EPS) / Previous EPS x 100
Annualized EPS growth = (Current EPS / Previous EPS)^(1 / Years) – 1
PEG ratio = Price-to-earnings ratio / Annualized EPS growth rate
Price-to-earnings ratio = Current share price / Current EPS
Here previous EPS means the earlier earnings per share value, current EPS means the latest earnings per share value, EPS change means the dollar increase per share, total EPS growth means the overall percentage growth across the full period, annualized EPS growth means the average compounded yearly growth rate, price-to-earnings ratio means current share price divided by current EPS, and PEG ratio means the valuation multiple compared with the annualized growth rate.
Solved Example
Example 1: Find EPS growth if previous EPS is $2.50, current EPS is $3.50, the period is 3 years, and current share price is $42.
Solve: EPS change = 3.50 – 2.50 = $1.00
Total EPS growth = (3.50 – 2.50) / 2.50 x 100 = 40.00%
Annualized EPS growth = (3.50 / 2.50)^(1/3) – 1 = 11.8689%
Price-to-earnings ratio = 42 / 3.50 = 12.0000
PEG ratio = 12.0000 / 11.8689 = 1.0110
Example 2: Find the result if previous EPS is $1.80, current EPS is $2.70, the period is 4 years, and current share price is $32.40.
Solve: EPS change = $0.90
Total EPS growth = 50.00%
Annualized EPS growth = 10.6682%
Price-to-earnings ratio = 32.40 / 2.70 = 12.0000
PEG ratio = 12.0000 / 10.6682 = 1.1248
Example 3: Find the result if previous EPS is $4.00, current EPS is $5.20, the period is 2 years, and current share price is $62.40.
Solve: EPS change = $1.20
Total EPS growth = 30.00%
Annualized EPS growth = 14.0175%
Price-to-earnings ratio = 62.40 / 5.20 = 12.0000
PEG ratio = 12.0000 / 14.0175 = 0.8561

How to use this earnings per share growth calculator
Enter the previous earnings per share in the proper input field. After that, enter current earnings per share, the number of years between the two EPS values, and the current share price. Then click the calculate button. The calculator will show EPS change, total EPS growth, annualized EPS growth, and PEG ratio in the result box.
This calculator is especially useful when comparing companies that look similar on headline earnings but are growing at different speeds. One business may show modest current EPS but excellent long-term growth, while another may show a high current EPS with slower growth. The annualized EPS growth output helps smooth the growth path across multiple years, and the PEG ratio helps connect that growth to market valuation in a simple way. That combination makes the page useful for stock screening, peer comparison, and basic growth-investing analysis.
When using the result, remember that EPS growth can be influenced by share buybacks, one-time gains, restructuring charges, tax effects, and accounting changes. A very high recent growth rate may not be sustainable, and a low or negative growth rate may be temporary if the business is moving through a weak cycle. The PEG ratio is also only a shortcut and should never replace deeper valuation work. Even so, this calculator gives a clear and practical first-pass way to measure per-share earnings growth and connect that growth with stock valuation.
