This calculates the Effective APY for a bank account bonus given the amount invested, the sign up bonus to be received, the days required for it to be on deposit, a variable number of buffer (cushion) days at your discretion, any fees to be paid as well as any interest the targeted bank account pays out. (Disclaimer: use this calculator at your own risk — you should manually verify the calculator is working according to your expectations.)
