Cumulative price change | 91.00% |

Average inflation rate | 2.34% |

Price difference ($1 base) | $0.91 |

CPI in 1990 | 130.7 |

CPI in 2018 | 248.991 |

CPI in 2018 / CPI in 1990 * 1990 USD value = 2018 USD value

Then plug in historical CPI values. The U.S. CPI was 130.7 in the year 1990 and 248.991 in 2018:

248.991 / 130.7 * $1 =

$1 in 1990 has the same "purchasing power" as $1.91 in 2018.
