Retirement savings growth projects a balance from what you have now, a salary, the percent of salary you contribute, and the percent of salary an employer adds. Age is only there to count the years.

**Key takeaways**

- Annual addition = salary × (your percent + the employer percent).
- That addition is split into 12 end-of-month contributions. The return compounds monthly.
- From age 30 to 65, $20,000 saved, an $80,000 salary, 10% from you, a 4% match, and a 7% return ends near **$1,911,107**.
- The match percent is the share of salary the employer actually adds. It is not a tier such as "50% of the first 6%."

## The formula

> **Annual addition = salary × (your contribution percent + employer match percent)**

Salary stays flat. So do both percents and the return. The years are retirement age minus current age.

## A worked example

Current age **30**, retirement age **65** (35 years). Current savings **$20,000**. Salary **$80,000**. You contribute **10%**. The employer adds **4%** of salary. Annual return **7%**. Inflation **2.5%**.

- Annual addition = $80,000 × (0.10 + 0.04) = **$11,200**.
- Nominal balance at 65 ≈ **$1,911,107**.
- In today's dollars at 2.5% inflation, that is about **$805,285**.

The inflation line restates purchasing power. It does not change the nominal balance. Try the inputs in the [retirement savings calculator](https://www.marketcaplens.com/tools/retirement-savings-calculator).

## What the projection tells you

It shows how a flat savings rate and a flat match compound over a long stretch of years. The interesting split is money contributed versus growth, and nominal dollars versus today's dollars.

## What the projection leaves out

Raises, contribution limits, catch-up rules, and taxes on the way in or out are absent. The return does not vary. A pension or Social Security check is not subtracted from the spending you might need later.

A company page such as [Apple](https://www.marketcaplens.com/company/AAPL) shows a share price. It is not a retirement balance.

## Frequently asked questions

### How does an employer match enter the projection?

Type the match as a percent of salary, the amount the employer actually adds. A 4% match on an $80,000 salary is $3,200 a year. With a 10% contribution from you, the annual addition is $11,200. This is not a tiered match such as 50% of the first 6%.

### What does the inflation-adjusted balance show?

It restates the nominal ending balance in today's dollars at the inflation rate you type. From age 30 to 65 in the worked example, about $1,911,107 nominal is about $805,285 in today's dollars at 2.5% inflation.
