401(k) Calculator Formula

Your 401(k) will increase due to your current savings, employee contributions, employer contributions and return.

To estimate how much you will have in your 401(k) if you are making regular monthly contributions and have a monthly return we can use the following formula:

FV = P(1+r)n + C[(1+r)n-1]/r

Where:

FV = Future value of your 401(k) (estimate)

P = Current 401(k) balance

r = Monthly return (annual return / 12)

n = Number of months (Years x 12)

C = Total of employee and employer contributions per month.

To estimate your monthly contributions use the formula:

C = (S x E)/12 + M

Where:

S = Salary

E = Employee contribution (% as a decimal)

M = Monthly employer match.

The employer match will depend on your company. For example if your employer is offering 50% up to 6% then the maximum contribution from your employer will be 3% of your salary.

If your return is 0% then the formula will be:

FV = P + (C x n)

This assumes contributions are made at the end of the month. Contributions and returns may be different.

Example

Let’s say you are 35 and want to know how much you will have in your 401(k) when you reach 65. You have the following details:

Input Value

Current 401(k) Balance $25,000

Salary $75,000

Employee Contribution 10%

Employer Match 50% up to 6%

Expected Return 7%

Years Until Retirement 30

2. Employee Contribution

75,000 x 10% = $7,500

Your employee contribution is $7,500.

3. Employer Contribution

Your employer offers 50% up to 6%. As you are contributing 10% you will receive the maximum. So:

75,000 x 6% x 50% = $2,250

Your employer will contribute approximately $2,250.

4. Total Contributions

$7,500 + $2,250 = $9,750

This means you are contributing a total of $9,750, or approximately $812.50 per month.

5. Future Value

To estimate how much you will have in the future, using a 7% return compounded monthly:

$1,073,000

Note: This is just an example and assumes you have a consistent return each month equal to 7% and contributions at the end of each month.

This shows how regular contributions, employer match and investment growth can help you save for your retirement. Your actual contributions will vary depending on your investment performance, fees, timing of contributions and plan.

Accuracy

This is simply an estimate based on the information you put in.

It generally assumes you will have a consistent return each year and regular contributions. In reality your return will vary.

Your results may not take into consideration investment fees, administrative costs, inflation, tax, withdrawals, loans and salary and contribution increases.

Traditional 401(k)s are generally pre-tax meaning you won’t pay federal income tax on your contributions. Roth 401(k)s are post-tax meaning you will pay tax on your contributions. Your projected balance shouldn’t be seen as how much you will have in your retirement as it doesn’t take into consideration tax.

Match rules, vesting, contribution limits and eligibility will vary between plans. Contribution limits can vary each year. There may be catch up rules.

For a more accurate estimate check your employer’s plan details, investments and fees. Speak with a qualified financial or tax professional before making any important decisions.
