## How is principal and EMI calculated?

E = P x r x ( 1 + r )n / ( ( 1 + r )n – 1 ) where E is EMI, P is Principal Loan Amount, r is monthly rate of interest (For eg. If rate of interest is 14% per annum, then r = 14/12/100=0.011667), n is loan duration in number of months.

## How do I calculate an interest rate?

How to calculate interest rate

1. Step 1: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate.
2. I = Interest amount paid in a specific time period (month, year etc.)
3. P = Principle amount (the money before interest )
4. t = Time period involved.
5. r = Interest rate in decimal.

## What is difference between amount and principal?

## How do you calculate interest with time and principal?

Simple Interest Formulas and Calculations:

1. Calculate Interest, solve for I. I = Prt.
2. Calculate Principal Amount, solve for P. P = I / rt.
3. Calculate rate of interest in decimal, solve for r. r = I / Pt.
4. Calculate rate of interest in percent. R = r * 100.
5. Calculate time, solve for t. t = I / Pr.

## What are mathematical terms?

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
