In 2023, Nitai (age 40) contributes 8 percent of his $122,000 annual salary to a Roth 401(k) account sponsored by his employer, AY Incorporated. AY Incorporated matches employee contributions dollar-for-dollar up to 8 percent of the employee's salary. However, AY matches by contributing to the employee's traditional 401(k) account because the employer contributions are not fully vested to the employee at the time of the contribution. Nitai expects to earn a 8 percent before-tax rate of return
