You can open an account and begin the process of saving with any amount, but the minimum to purchase a U.Plan Tuition Certificate is $300. If you have at least $300 in your account at the time of the bond purchase in mid-July, your contributions will be used to purchase Tuition Certificates and will lock in that percentage of tuition and fees at each participating Massachusetts college and university. If you do not have $300 in your account at the time of the bond purchase, then your funds will remain in your money market account and will not be used to purchase U.Plan certificates that year.
