Examples
Eighty extra jerseys on Saturday
You run a print shop, and on May 12 a rec league asks if you can add 80 jerseys to Saturday pickup at $17 each, or $1,360. Blank tees, ink, and screens from a blank-tee supplier add $520, and two hours of press help add $140; shop rent and your salary do not change. Marginal balance is $1,360 minus those variable costs, $700 leftover to cover overhead and profit. Invoice the rec league and enter that supplier's bill; do not add a marginal-balance account. Take the extra 80 if that leftover is worth the Saturday hours, not if May net income after rent looks thin.
Funeral work after allocated salary
You run a florist shop. After December close you export a funeral-work P&L: $18,400 invoiced to a chapel, $6,100 of flowers and foam from a flower grower, plus $4,200 of shop rent and $3,000 of your salaried designer's pay allocated to funerals. The export shows $5,100 left, so you plan to drop chapel work, but rent and that salary do not move if you stop funerals. Marginal balance is $18,400 minus $6,100, or $12,300 left to help pay those fixed costs. Keep the chapel work if that leftover still covers overhead; do not treat an allocated-rent net as the test.
Why it matters
Marginal balance is the leftover after you subtract only the costs that move with sales. You do not post an account with this name; you compute it when you price a job, add a shift, or decide whether a line still helps pay rent, not every close. Treat it as margin and you are looking at gross profit, which can include costs that do not change with one more sale; marginal-income subtracts direct costs, a close set that is not always strictly variable; marginal cost is the extra cost of one more unit, not the leftover. Subtract rent and salaried pay as if they were variable and a line that still covers overhead looks like a loser.
