With this percentage calculator, you can find the value that makes up the percent portion of a percentage equation. You can also calculate percent when the amount and value are known, or find the original amount when the value and percent are known.
Answer questions like % of X, what % is X in Y, or X is Y% of what? can be calculated using this tool.
Here are the three components required for a percentage formula:
By knowing the principal amount (P) and the percentage rate (R), we can easily calculate the interest amount (I).
Percentage Amount = Principal Amount x Percentage Rate / 100
That means multiplying the original amount by the percentage and dividing by 100.
If the interest amount (Interest) and the percentage rate (Percentage) are known, we can easily find out the actual amount (Principal)....
Principal Amount = Interest Amount x 100 / Percentage Rate
That is, the interest amount must be multiplied by 100 and divided by the percentage rate.
Similarly, if the principal (P) and interest amount (I) are known, the formula to find the percentage is (%).
Percentage Rate = Interest Amount x 100 / Principal Amount
That is, the interest amount multiplied by 100 is divided by the principal amount.
