New vs Used Comparison

The New vs Used Comparison substitutes your inputs (New car price, Used car price, New car yearly maintenance, Used car yearly maintenance, Years of ownership) into the standard expression: New car total cost = New car price + New car yearly maintenance × Years of ownership; Used car total cost = Used car price + Used car yearly maintenance × Years of ownership; New minus used (− = used cheaper) = New car price + New car yearly maintenance × Years of ownership − (Used car price + Used car yearly maintenance × Years of ownership). Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

   Step 4

   Review the breakdown: the new vs used comparison shows each of your inputs substituted into the page's standard expression, so every variable stays traceable.

5. 5

   Step 5

   Compare scenarios by varying a single value per run in the new vs used comparison — that isolates which of the formula's inputs actually drives the result.

• 1

  The New vs Used Comparison needs every variable in consistent units — New car price, Used car price — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Copy the New vs Used Comparison result together with the input values that produced it; a number without its documented inputs cannot be re-verified later, and assumptions are easy to forget once the session is closed.

• 3

  Round only at the end: New vs Used Comparison carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• Percentage conventions differ by field: some New vs Used Comparison inputs expect used car price as a whole number (5 for 5%), others as a decimal (0.05). The two forms are off by ×100 — match the field's label or example.

• New car price and Used car price must be entered in one consistent unit system: months against years skews the New vs Used Comparison result silently. Convert every input to the unit named on its field first.
