If you want to prepay for college, you have only until Tuesday to lock in this year’s prices.

While the $49,293 price tag for a four-year university plan may seem pricey, the cost will likely increase even more next year. The prices include tuition and most mandatory fees. Cheaper plans for state colleges are also available.

If you bought a university plan between February 2007 and January 2010, you may also want to consider adding a "tuition differential" plan to cover the extra tuition that universities can charge above the state rate. It was sold as an optional plan during that time period, and most people didn’t buy it. But without it, you may be covered for less than half the costs of tuition and fees. The plan costs about $21,000.
