Testopedia explains Contractual Plan
An investor may elect to purchase mutual fund shares though a contractual plan when the investor can not meet the minimum investment required by the fund company. In cases where a mutual fund has a very high minimum investment a contractual plan will offer the investor the ability to invest in the fund over time through the plan.
