Current ratio = current assets ÷ current liabilities. $250,000 of current assets against $120,000 of current liabilities gives 2.08.
Enter current assets and current liabilities. The calculator returns the current ratio.

Formula and method
Formula
Current ratio = current assets ÷ current liabilities
IEEE-754 double precision; shown to the decimals indicated.
Use the same period and unit for both numbers.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Current assets = 250000; Current liabilities = 120000.
| Result | Value |
|---|---|
| Current ratio | 2.08 |
Example 2
Inputs: Current assets = 80000; Current liabilities = 100000.
| Result | Value |
|---|---|
| Current ratio | 0.8 |
The first line is the headline result (current ratio). IEEE-754 double precision; shown to the decimals indicated.
Reading 2.08
The business holds $2.08 of short-term assets for every $1 due within a year. A ratio above 1 means it can cover short-term debts from current assets, and 1.5 to 2 is often cited as comfortable, but norms vary by industry.
Where this estimate stops applying
The ratio treats all current assets alike, including slow-moving inventory. The quick ratio excludes inventory for a stricter test. A very high ratio can also mean idle cash or excess stock.
How the result changes with current assets
Holding every other input at the first worked example, this table changes only current assets. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Current assets | Current ratio |
|---|---|
| 125000 | 1.04 |
| 250000 | 2.08 |
| 500000 | 4.17 |
| 1000000 | 8.33 |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Current assets: entering "0" shows "Current assets must be greater than 0." beside that field and no result.
- Current liabilities: entering "0" shows "Current liabilities must be greater than 0." beside that field and no result.

Background: business metrics
Business ratios depend on exactly which costs and revenues you include, so read each page's definition. Two common checks: break-even units = fixed costs ÷ (price − variable cost per unit), so $50,000 of fixed costs with a $10 price and $5 variable cost breaks even at 10,000 units; and net profit margin = net profit ÷ revenue, so $20,000 profit on $100,000 revenue is 20%.
Return on investment ignores time: 20% over five years is far less impressive than 20% in one, so compare returns over the same period.
Assumptions and limitations
- Denominator must be positive
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for current assets and current liabilities to confirm this.
