Mortgage overpayments

Can anyone tell me as I do not have a mathematical head.
If you had a new 30 year mortgage of £152000 with an 2 year introductory rate of 1.34% then for the remaining 28 years is 3.74% and you made a £100 overpayment for the first 3 years how much would you actually save?
I am trying to convince someone it is better to have that small monthly overpayment now rather than years down the line.
Sorry if this is a silly thing to ask?
