### What Is Periodic Compound Interest?

Periodic Compound interest is standard in finance and economics . Periodic Compound interest calculator is use to
calculate Future Value(A) , Initial Deposit(P) , Rate of Interest(r) , Time Period(t) by using Periodic Compound Interest formula .
Periodic Compound Interest formula is as follows -:

**Compound Interest Equation**

**A = P (1 + r)**^{t}

Where

A = Future Value(Principal + Interest)

A = P + I

P = Initial Deposit Amount

I = Interest Amount

r = Rate of interest per period in decimal

R = Rate of interest per period in percent

r = R / 100

t = Number of years invested tenure

**Initial Deposit:**

P = A / (1 + r)^{t}

Where

P = Initial Deposit

A = Future Value

r = Rate of interest

t = Number of years invested in tenure

**Interest in Decimal:**

r = ( A / P)^{1/t}-1

Where

r = Rate of Interest in decimal

P = Initial Deposit

A = Future Value

t = Number of years invested in tenure

**Interest in Percent:**

R = r * 100

Where

R = Rate of Interest in Percent

r = Rate of Interest in decimal

**Time:**

t = ln(A / P) / ln(1 + r)

Where

t = Number of years invested in tenure

r = Rate of Interest in decimal

P = Initial Deposit

A = Future Value
