Net Price Calculator | Harvard shows a net price of $3,500 (student work expectation) for parent income of $75,000 and no parent or student assets for a US domestic student in a household of 3 with 1 in college.
At $76,000 for the same other parameters, it goes to $5,000, including a $1,500 parent contribution.
I.e. it looks like the net price calculator is updated in line with the announcement, and you can try example scenarios with it for the newly announced financial aid.
