What the source says, and what the calculator adds
What changes the answer
A percentage becomes a cash-flow commitment
Monthly and paycheck views reveal whether the headline rule fits the household budget before long-run compounding enters the discussion.
The return assumption can dominate the picture
Use the rate control to see how much of the terminal value comes from contributions versus an assumed market path.

- BJavier EstradaProfessor of finance at IESE Business School, Barcelona, publishing in The Journal of Wealth ManagementNarrows the rule
6.5% annual compound real US equity return, 1900-2014, at 20.0% volatility
Estrada’s retirement study runs on the Dimson, Marsh and Staunton series, and reports the long-run US equity return in the form an investor can actually spend: compound, and after inflation. Over 1900 to 2014 that figure is 6.5% a year with 20% annual volatility. It is not the same measure as an 11% nominal average of annual returns and should never be swapped for it, which is precisely the point: the gap between the two is where optimistic retirement plans live.
stocks and bonds had mean annual compound (real) returns of 6.5% and 0.9%, with annual volatility of 20.0% and 4.6%
The Journal of Wealth ManagementMar 31, 2016Buffett’s Asset Allocation Advice: Take It … with a TwistSpring 2016 issue, page 61, opening sentence of the page, describing the Dimson-Marsh-Staunton data used in the study’s 1900-2014 sample.
Fifteen percent is a good number. The return it gets illustrated with is where the trouble starts.
As a savings rate, 15% of gross income is defensible and easy to act on, which is most of what a rule has to do. The part JMM would not copy is the growth assumption sitting next to it. Ramsey’s own retirement page runs its example at an 11% annual return, described there as the average from 1928 through 2025. That is a nominal figure and it is not spendable: inflation takes roughly three points of it before you buy anything, and an average of annual returns always sits above the compound rate an investor actually earns. Set the return control to 7% and watch how much of the ending number disappears. If the plan only works at 11%, it is not a plan, it is a hope with a spreadsheet attached.
Not the calculator’s limits. The rule’s.
A flat percentage ignores where you are starting from
Fifteen percent from 25 and 15% from 50 are not the same instruction. A late starter who follows the rule literally can still land short, because the rule sets the contribution and says nothing about the target.
Gross income is the wrong base for a high earner in a high-tax state
Fifteen percent of gross can exceed what the tax-advantaged accounts will take, which pushes the balance into taxable investing the rule never discusses.
What this model does not know
- The return rate is your scenario, not a Ramsey or JMM forecast.
- Taxes, fees, contribution limits, vesting, and account type are excluded.
- The rule assumes earlier Ramsey steps are already complete.
Before you use the result
Does employer match count toward the 15%?
The cited current Ramsey page says the personal contribution reaches 15% before employer match.
Is 7% the promised return?
No. It is an editable default scenario used only to make the calculator useful on first load.
The next question this page cannot answer
- Guide The average return you were quoted is not the return you earned
Why the 11% average on the source page is not 11% earned. The gap between an average of annual returns and the compound rate is the whole argument on this page.
