Spending Calculator - Figures True Cost To Own

When you spend money instead of invest it you choose consumption today over a lifetime of interest income. The total amount of money you spend on consumption plus the forgone interest earnings adds up to the real cost of spending. Warning! This number is much higher than you might expect because of compound interest. Using this calculator encourages thrift and wise spending choices by looking at the lifetime, true cost of a one-time expense today.

Below are a few things to keep in mind:

  • Some people like to use 10% as an interest assumption based on studies about long-term stock market returns. Others choose 6% or 8% to approximate bond market returns.
  • If you invest your savings in paying off high interest debt such as credit cards, you could safely assume an even better return.
  • Be sure to include any sales taxes that might apply when entering expenditure amounts.
  • Some items you buy come with additional costs of ownership -- such as repair and maintenance costs, operating costs (gas, electricity, etc.), insurance costs, storage costs, etc. Try this latte factor calculator to show how much regular, periodic spending can add up. It will shock you!
  • The calculations do not account for inflation.
