How it works

Seeing the real price

  • What you spend: enter a one-time purchase, a regular expense, or both.
  • A rate to compare: pick a yearly growth rate you want to measure against.
  • The trade-off: see the total spent next to what it could have grown to.

What this assumes

A steady yearly growth rate that you choose, with each amount growing from the time it is spent. Real growth rates change over time and are not promised. Taxes and fees are not included.
