The Formula

Pro Forma Net Income = Acquirer NI + Target NI + Synergies − After Tax Financing Cost

Pro Forma Shares = Acquirer Shares + New Shares Issued

Pro Forma EPS = Pro Forma NI ÷ Pro Forma Shares

Accretion % = (Pro Forma EPS ÷ Acquirer EPS − 1) × 100

Stock deals use exchange ratio for new shares. Cash deals add after tax interest on new debt. Synergies should be phased realistically.

Limitations and assumptions
