Did you know?

Ratios appear in the earliest Greek mathematics (Eudoxus, 4th century BCE) as a way to compare incommensurable lengths without a concept of irrational numbers.

§01What is

Understanding the Profitability Ratios Calculator

The Profitability Ratios Calculator computes Net margin from 3 inputs: revenue ($), net income ($), total assets ($). Profitability ratio analysis.

Quick calculators for the math that shouldn’t need a notepad — instant, accurate, private to your browser. The Profitability Ratios Calculator sits in that toolkit — it profitability ratio analysis. Enter your numbers above and the result updates instantly; every step of the math is shown in the Derivation panel so you can see exactly how the answer was reached.

§03Practical Example

Step-by-step walkthrough

Scenario

Apply the formula to a realistic set of inputs: Revenue ($) = 1000000, Net income ($) = 150000, Total assets ($) = 800000.

  1. 01Start by noting the input — Revenue ($): 1000000.
  2. 02Start by noting the input — Net income ($): 150000.
  3. 03Start by noting the input — Total assets ($): 800000.
  4. 04Substitute these values into the formula: Net margin = e.net / t × 100 | ROA = e.net / e.assets × 100
  5. 05Compute Net margin: the calculator returns 15.
  6. 06Compute ROA: the calculator returns 18.75.
  7. 07Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.

Common Profitability Ratios Problems

The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.

01 · PATTERN

Revenue ($) halved

rev = 500000 (from 1000000)

Keep every other input at its default and halve the revenue ($). See how net margin responds.

  1. 01New Revenue ($): 500000
  2. 02Baseline Net margin: 15
  3. 03New Net margin: 30
  4. 04Net margin increases by 100% → use this sensitivity to plan for real-world variation.
02 · PATTERN

Revenue ($) doubled

rev = 2000000 (from 1000000)

Keep every other input at its default and double the revenue ($). See how net margin responds.

  1. 01New Revenue ($): 2000000
  2. 02Baseline Net margin: 15
  3. 03New Net margin: 7.5
  4. 04Net margin decreases by 50% → use this sensitivity to plan for real-world variation.
03 · PATTERN

Net income ($) halved

net = 75000 (from 150000)

Keep every other input at its default and halve the net income ($). See how net margin responds.

  1. 01New Net income ($): 75000
  2. 02Baseline Net margin: 15
  3. 03New Net margin: 7.5
  4. 04Net margin decreases by 50% → use this sensitivity to plan for real-world variation.
04 · PATTERN

Net income ($) doubled

net = 300000 (from 150000)

Keep every other input at its default and double the net income ($). See how net margin responds.

  1. 01New Net income ($): 300000
  2. 02Baseline Net margin: 15
  3. 03New Net margin: 30
  4. 04Net margin increases by 100% → use this sensitivity to plan for real-world variation.
