Example

20% of 150 = 30.

Watch for

Use it when the percent and base value are known; the result is a number, not a percent.

Example

30 out of 150 = 20%.

Watch for

Use it for shares, completion rates, and ratios; the second value is the whole.

Example

30 is 20% of 150.

Watch for

Use it when the whole is missing; the percentage cannot be 0.

Example

100 to 125 = 25% increase.

Watch for

The original value is the baseline, so reversing the order changes the answer.

Example

150 plus 20% = 180.

Watch for

Use it for markup, tax, tips, or growth; the result is the final value after the increase.

Example

150 minus 20% = 120.

Watch for

Use it for discounts, markdowns, or deductions; the result is the final value after the decrease.

Example

80 after 20% off started at 100.

Watch for

Choose decrease for discounts and increase for growth; this mode works backward from the final value.

Example

40 and 50 differ by 22.2222%.

Watch for

Use it when neither value is the original baseline; it uses the average of both values.
