What’s the formula for the future value of continuous compounded interest with an initial amount and annuity/monthly payments/investments?

How do you calculate future value of continuous compounding?

FV = PV (1 + r n )nt. In the case of continuous compound interest, the formula is given by FV = PVert. Example 6.5. 1 You need $10,000 in your account 3 years from now and the interest rate is 8% per year, compounded continuously.

How do you calculate the future value of an annuity compounded monthly?

The two basic annuity formulas are as follows:

  1. Ordinary Annuity: FVA = PMT / i * ((1 + i) ^ n – 1)
  2. Annuity Due: FVA = PMT / i * ((1 + i) ^ n – 1) * (1 + i) n = m * t where n is the total number of compounding intervals. i = r / m where i is the periodic interest rate (rate over the compounding intervals)


What is the correct formula for continuously compounded interest?

The continuous compounding formula says A = Pert where ‘r’ is the rate of interest. For example, if the rate of interest is given to be 10% then we take r = 10/100 = 0.1.

How do you calculate interest compounded monthly and future value?


Quote: I is decimal value of rate of interest during the compounding period now in this case the rate of interest is four point five percent that means four point five divided by 100.

What is the formula of future value of annuity?

The formula for the future value of an ordinary annuity is F = P * ([1 + I]^N – 1 )/I, where P is the payment amount. I is equal to the interest (discount) rate. N is the number of payments (the “^” means N is an exponent). F is the future value of the annuity.

How do you find the initial investment compounded continuously?

Continuous Compound Interest Formula: To find the future value, A , of an initial investment, P , after a certain amount of time (in years), t , at an interest rate of r , we use the formula A=Pert A = P e r t .

How do you calculate future value?

The future value formula

  1. future value = present value x (1+ interest rate)n Condensed into math lingo, the formula looks like this:
  2. FV=PV(1+i)n In this formula, the superscript n refers to the number of interest-compounding periods that will occur during the time period you’re calculating for. …
  3. FV = $1,000 x (1 + 0.1)5


How do you find the future value of a monthly payment?

P = PMT [((1 + r)n – 1) / r]



This value is the amount that a stream of future payments will grow to, assuming that a certain amount of compounded interest earnings gradually accrue over the measurement period.

When the future value of an ordinary annuity is computed the number of compounding periods will always be?

Any time the future value of an ordinary annuity is computed, the number of compounding periods will always be: one less than the number of rents. A deferred annuity is one in which the rents begin: after a specified number of periods.

What is the formula of future value compounded monthly?

Formula 9.3, FV=PV(1+i)N, places the number of compound periods into the exponent. The 8% compounded monthly investment realizes 60 compound periods of interest over the five years, while the 8% compounded annually investment realizes only five compound periods.

What is future value of compound interest?

The future value formula (compound interest) thus helps in calculating the final amount, which includes the initial investment along with total interest. In compound interest, The “present value” represents the initial investment. The “future value” represents the final amount (initial investment + total interest).

What is the formula for the rate of interest of an investment compounded monthly?

The monthly compound interest formula is used to find the compound interest per month. The formula of monthly compound interest is: CI = P(1 + (r/12) )12t – P where, P is the principal amount, r is the interest rate in decimal form, and t is the time.

What is the formula of compound interest with example?

Compound Interest Formula Continuous

Time Compound Interest Formula
6 months [Compounded half yearly] P[1 + (r/2)2t] – P
3 months [Compounded quarterly] P[1 + (r/4)4t] – P
1 month [Monthly compound interest formula] P[1 + (r/12)12t] – P
365 days [Daily compound interest formula] P[1 + (r/365)365t] – P

How do you find the interest rate in compound interest?

A = amount. P = principal. r = rate of interest. n = number of times interest is compounded per year.



Interest Compounded for Different Years.

Time (in years) Amount Interest
3 P ( 1 + R 100 ) 3 P ( 1 + R 100 ) 3 − P
4 P ( 1 + R 100 ) 4 P ( 1 + R 100 ) 4 − P
n P ( 1 + R 100 ) n P ( 1 + R 100 ) n − P
