amount x APR

First, your interest rate is not the same as APR, which depends on how often you make payments. 2.75% interest rate may be 2.9% APR.

Second, your interest saving would be (early payment amount * (APR / number of payment in a year) *　remaining number of payments).

Of course, this is only estimate, since the last few payment would be applied to the principal that is less than the "early payment amount".
