Retirement age must be greater than your current age.
Employer match model: a simple match is assumed — your employer matches your contribution dollar-for-dollar up to the match cap. The matched percent equals min(your contribution %, employer match %) of salary. Real plans vary (e.g. 50% of the first 6%), so treat this as an approximation.

How a retirement calculator works

A retirement calculator projects your savings at retirement by compounding your current balance plus your ongoing monthly contributions, including any employer match, at an expected annual return until your retirement age.

How is a retirement balance projected?

Future value is A = B x (1 + i)^n + C x (((1 + i)^n - 1) / i), where B is your current balance, C is the monthly contribution (your part plus employer match), i is the monthly return, and n is the months until retirement. Estimates only, not financial advice.

How does an employer 401k match work?

Many employers match your contributions up to a percentage of salary. This calculator assumes a dollar-for-dollar match on the lesser of your contribution rate and the match cap. Real plans vary, such as 50 percent of the first 6 percent, so check your plan details.

What return rate should I assume for retirement?

A common long-run assumption for a diversified stock and bond portfolio is around 6 to 7 percent per year before inflation. Use a conservative figure, since actual returns vary and past performance does not guarantee future results.
