Interest rate future

Sir in your lecture, when calculating the “FUTURE PRICE” at transaction date you have calculated the basis as follow

Basis= (100 – Libor rate) – Future price

now i want to calculate Lock in rate for future at transaction date so does this lock in rate indicate the Libor lock in rate???

Do i have to calculate “overall expected lock in rate” to calculate the outcome of future hedge???
(Overall expected lock in rate means = Libor lock in rate + credit spread)

So which one is the actual future price at transaction date “libor lock in rate” or “overall expected lock in rate”

I hope you understand what i m trying to say
