Working Capital and Current Ratio Calculator

How to use this working capital and current ratio calculator

1. Current assets: enter the amount in your selected currency. The worked example uses $100,000.00.
2. Current liabilities: enter the amount in your selected currency. The worked example uses $60,000.00.
3. Inventory included in assets: enter the amount in your selected currency. The worked example uses $25,000.00.
4. Prepaid expenses included in assets: enter the amount in your selected currency. The worked example uses $5,000.00.

Start with figures from the same statement date or planning period. Calculate once, save scenario A, then change one assumption to understand its effect. The comparison shows B minus A; a positive difference means the result increased, which is not automatically better.

Formula and calculation method

Working capital = current assets − current liabilities; current ratio = assets / liabilities; quick ratio = (assets − inventory − prepaids) / liabilities.

The calculator evaluates this relationship directly in your browser. The displayed precision is for readability and does not imply a guaranteed outcome. Time periods and rate conventions matter: use the exact units in each input label and avoid mixing monthly and annual values.

What the result means

A business can have positive working capital yet struggle to pay bills if assets are tied up in inventory or slow receivables. The quick ratio removes inventory and prepayments from the numerator.

Two worked examples

1. Illustrative planning scenario

Current assets = $100,000.00; Current liabilities = $60,000.00; Inventory included in assets = $25,000.00; Prepaid expenses included in assets = $5,000.00.

Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.

2. Simplified calculation check

Current assets = $100,000.00; Current liabilities = $50,000.00; Inventory included in assets = $20,000.00; Prepaid expenses included in assets = $5,000.00.

Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.

The second example uses simpler inputs to make the arithmetic easier to check. It is also included in the automated regression suite. These examples illustrate the model and are not market averages, live offers or personalized advice.

Assumptions and limitations

Balance-sheet snapshot only. All components must use the same reporting date; ratios do not model collection timing, restricted cash or industry-specific liquidity needs.

Use this output to frame a question or compare consistent scenarios. Reconcile any decision involving an actual product, employment agreement or financial statement with its underlying documents. If a contract uses different rounding or timing, its result may differ from this estimate.
