While it may not be your intention, it is really bad form to hijack another poster’s thread.
Harvard’s financial aid website along with their net price calculator are your friends.
Harvard Financial aid states:
We determine parent contribution through a careful review of your family’s income, assets, and overall financial circumstances.
For families with annual incomes below $65,000, the expected contribution is zero. Families with annual incomes between $65,000 and $150,000 will contribute between 0 and 10 percent of their income. Those with incomes above $150,000 will be asked to pay proportionately more than 10 percent based on their circumstances.
Families who have significant assets will be asked to pay more, but home equity and retirement assets are not considered in our assessment of financial need.
Parents may provide their contribution from savings, current income, future income (through borrowing), or a combination of these methods.
You can use our net price calculator to estimate your expected family contribution.
