## How do you calculate 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.

## How do you calculate interest on a calculator?

How does Simple Interest Calculators work? Interest = A – P. Let’s understand the workings of the simple interest calculator with an example. The principal amount is Rs 10,000, the rate of interest is 10% and the number of years is six.

## What is degree formula?

1° = (π)/180 radians. This gives us the formula to make conversions from degrees to radians and vice versa. Thus, to convert degrees to radians, use this formula = Degree measure × (π/180°). 1° = (π)/180 radians = 0.017453 radians.

## What is 0 APR mean?

In most cases, a 0 percent APR is a promotional interest rate that lets you borrow money at no cost for a fixed period, often between 12 and 18 months. During this time, you’ll still need to make payments each month, but you won’t be accruing any additional interest costs if you only make the minimum payments.

## What is the formula of mode?

L = Lower limit Mode of modal class. fm = Frequency of modal class. f1 = Frequency of class preceding the modal class. f2= Frequency of class succeeding the modal class….Mode Formula Calculator.

Mode Formula = L + (fm – f1) x h / (fm – f1) + (fm – f2)
= 0 + (0 – 0) x 0 / (0 – 0) + (0 – 0)= 0

## What is the formula of trigonometry?

Basic Trigonometric Function Formulas By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.
