Dave's Math Tables: Interest and Exponential Growth |

(Math | General | Interest and Exponential Growth) |

whereP = C (1 + r/n)^{ nt}

P = principal (current worth)

C = initial deposit

r = interest rate (expressed as a fraction: eg. 0.06)

n = # of times per year interest in compounded

t = number of years invested

P = C (1 + r)^{ t}

P = C e^{rt}

n | P |

1 (yearly) | $ 10600.00 |

2 (semi-anually) | $ 10609.00 |

4 (quarterly) | $ 10613.64 |

12 (monthly) | $ 10616.78 |

52 (weekly) | $ 10618.00 |

365 (daily) | $ 10618.31 |

continuously | $ 10618.37 |
