Pillar One

Consistent Contributions

Small, regular deposits do most of the work in a retirement plan. The habit matters more than the amount you start with.

A deposit made at 30 has decades to compound. The same deposit made at 55 has a few years. That gap, not the size of any single transfer, is what separates account balances at retirement.

  • 01Automation. Set the transfer for the day after payday, so the decision is made once and then repeats.
  • 02Escalation. Raise the percentage by one point each year, or with each raise, and let the increase arrive quietly.
  • 03Continuity. Pause only for a genuine emergency, then restart at the next pay cycle instead of waiting for a perfect month.

Compound growth

See what consistent contributions could compound into

Adjust the monthly amount, the time horizon, and the assumed annual return. The projection assumes the contribution is added at the end of each month and returns compound monthly. The inflation input shows what the ending balance would buy in today's dollars.

Rates are assumptions you choose, not forecasts. Small changes in either rate change the outcome a lot over three decades.

Projected balance year by year.
The line plots the projected balance at the end of each year. A larger contribution schedule, more years, or a higher return all steepen the curve, while inflation reduces what the final balance buys. Pair this with diversification to think about how returns are generated.

Assumption table

Contribution Schedule Over 30 Years

A steady monthly contribution is the engine of the whole framework. The table below shows what a $500 monthly contribution would look like at a fixed 6% assumed annual return, with no withdrawals and no fees.

Illustrative only. Returns are assumed, not guaranteed. Figures are not adjusted for inflation or fees.
Period Monthly Total contributed Assumed return Projected balance
Year 5$500$30,0006.0%$34,885
Year 10$500$60,0006.0%$81,940
Year 15$500$90,0006.0%$145,360
Year 20$500$120,0006.0%$231,020
Year 25$500$150,0006.0%$346,560
Year 30$500$180,0006.0%$502,200

Read the last two columns together. By year 30 the projected balance is roughly 2.8 times everything you put in. That gap is compound growth doing the work, not a larger contribution. See how compound growth builds.

None of these figures are adjusted for inflation. At 2.5% average annual inflation, the year 30 balance would buy noticeably less than it does today. That gap is covered in our inflation overview.

Changing the monthly amount changes every row above proportionally. Changing the allocation mix introduces asset class variation that a fixed assumed return cannot represent.

Sources and method

Where these contribution numbers come from

Every figure on this page traces back to a published limit, a long-run return series, or a price index. The citations are listed here so you can check each input yourself before you apply it to your own plan.

  1. 01

    Retirement Topics: Contribution Limits

    Internal Revenue Service · updated annually · irs.gov

    Primary reference for the annual employee deferral and IRA ceilings applied in the contribution schedule. Limits are indexed and change most years, so always pull the current-year figure.

  2. 02

    Consumer Price Index, All Urban Consumers

    U.S. Bureau of Labor Statistics · monthly series · bls.gov

    Used to build the inflation-adjusted returns referenced in the long-term planning framework. Rolling 20 and 30 year averages are more stable than any single year of price change.

  3. 03

    Long-Run Asset Class Return Series

    Published academic and industry indices · multi-decade windows

    Historical returns for broad stock and bond asset classes. Past performance does not predict future results, and diversification does not ensure a profit or protect against loss.

  4. 04

    Household Savings and Participation Data

    Federal survey and retirement industry research · annual

    Background for the participation rates and average balances quoted earlier on this page. Survey definitions vary, so comparisons across studies should be read with care.

All figures are educational illustrations, not projections of your personal outcome. Review the compound growth model and the contribution schedule, then confirm details with a licensed professional.
