What should your specific mix earn? Blend each asset's expected return by its weight and see where the portfolio lands — and what you give up vs all stocks.
Return follows your weights — every 1% shift between stocks and bonds moves the number.
Return alone lies. Divide by volatility and a 70/30 mix often beats 100% stocks on efficiency.
Monthly contributions plus compounding show the realistic end number.
