The interest rate will be 100 basis points or one percent.

The Administrator, in consultation with the Secretary, determined that a one percent interest rate is appropriate. First, it provides low cost funds to borrowers to meet eligible payroll costs and other eligible expenses during this temporary period of economic dislocation caused by the coronavirus. Second, for lenders, the 100 basis points offers an attractive interest rate relative to the cost of funding for comparable maturities. For example, the FDIC’s weekly national average rate for a 24- month CD deposit product for the week of March 30, 2020 is 42 basis points for non-jumbo and 44 basis points for jumbo (https://www.fdic.gov/ regulations/resources/rates/). Third, the interest rate is higher than the yield on Treasury securities of comparable maturity. For example, the yield on the Treasury two-year note is approximately 23 basis points. This higher yield combined with the fact that the loans are 100 percent guaranteed by the SBA and the fact that lenders will receive a substantial processing fee from the SBA provide ample inducement for lenders to participate in the PPP.
