[Verse 1]
Sarah's factory bought machines last year for quite a sum
Now she's choosing between two contracts, needs to understand
The machines are paid for, money's gone, that's history now
Focus on tomorrow's cash, forget the sunken vow
[Chorus]
Relevant cuts through the noise, future flows that change
Irrelevant stays the same, past payments can't arrange
If it alters with your choice, then it belongs
Sunk costs sing their silent songs
[Verse 2]
Contract A brings revenue of eighty every month
Contract B pays ninety, but needs workers for the hunt
Additional labor costs thirty for the second deal
Which path generates more? Let the differential reveal
[Chorus]
Relevant cuts through the noise, future flows that change
Irrelevant stays the same, past payments can't arrange
If it alters with your choice, then it belongs
Sunk costs sing their silent songs
[Bridge]
Depreciation on those machines stays constant either way
Rent and utilities continue, same amount each day
Strip away the static noise, isolate what moves
Differential analysis shows which option you should choose
[Verse 3]
Eighty minus zero costs for A equals eighty clear
Ninety minus thirty wages for B leaves sixty here
Though B seemed bigger at first glance, A's the better call
Relevant costs told the truth, irrelevant costs fall
[Chorus]
Relevant cuts through the noise, future flows that change
Irrelevant stays the same, past payments can't arrange
If it alters with your choice, then it belongs
Sunk costs sing their silent songs
[Outro]
Avoidable or escapable, these costs you can control
Unavoidable expenses play no decision role
When crossroads appear ahead, know which costs to heed
Relevant costs plant the seed
