My part time job earnings: Sometimes my calculations & estimations are damn near accurate. But lately, far from accurate 🤦🏼‍♀️

Because the past few months some factors have changed, like I started contributing 10% to the 401k, and our new manager raised all our service-based commissions which vary, but I know exactly the dollars & pennies of it all, still my calculations have been way out of left field 😵‍💫 and I'm losing trust in my own brain.
