Important thread - if you want to calculate for your own institution I made a little webapp: arbennett.github.io/nih_overhead... Results for University of Arizona:

Screenshot of example of the NIH Overhead Rate Impact Calculator for University of Arizona.

Total NIH Funding: 218588000
Current Overhead Rate: 53.5%

Financial Impact Analysis
When current level of direct costs are maintained

Calculated as:

directCosts = totalFunding / (1+oldRate)

newTotalFunding = directCosts * (1+newRate)

loss = newTotalFunding - directCosts
New Total NIH Funding

$163,762,997
New Overhead Amount (15%)

$21,360,391
Total Loss

$54,825,003
When current overhead is reallocated to direct costs (unlikely)

Calculated as: loss = total * ((1 - 1/oldRate) - 1 - 1/newRate)

Or in simplified terms: loss = (total/newRate) - (total/oldRate)
Current Overhead Amount

$76,185,394
New Overhead Amount (15%)

$28,511,478
Total Loss

$47,673,916
