About Vehicle Purchase Fund Calculator

Saving for a vehicle down payment needs the future on-road price, not today's, and a realistic upfront share. A larger down payment cuts both the loan and the interest, so the trade against saving longer is worth seeing explicitly.

Formula

Vehicle fund

Future price = price × (1+inflation)^years; monthly = target down payment / annuity factor

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take tax or fees or charges into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates for planning only. Prices, returns, inflation and personal circumstances all change. This is not financial or tax advice — speak to a qualified adviser before making decisions.

Frequently Asked Questions

How large should the down payment be?

At least 20% to avoid negative equity, and more if you plan to sell within a few years.

Should the fund be invested in equity?

For a horizon under three years, no. Capital certainty matters more than return on a near-term purchase.
