We werken aan een uitgebreide educatieve gids voor de Freelance Retirement Planner. Kom binnenkort terug voor stapsgewijze uitleg, formules, praktijkvoorbeelden en deskundige tips.
The Freelance Retirement Planner projects retirement nest-egg value for self-employed workers who lack the employer 401(k) match that's central to traditional retirement math. Standard W-2 retirement assumes employee contribution + employer match (typically 3–6% of salary in 'free money'); freelancers must contribute the full amount themselves, but get access to higher contribution limits via SEP-IRA (up to 25% of net self-employment income, capped at $69,000 in 2024) or Solo 401(k) (employee $23,000 + employer-side 25% of net SE income, total cap $69,000, plus $7,500 catch-up if 50+). The calculator uses standard compound interest with annual contributions: FV = P × (1+r)^n + PMT × ((1+r)^n − 1) / r, where P is current savings, r is annual return, n is years to retirement, and PMT is annual contribution. Default 7% real return matches long-term US equity market average after inflation; 5% is conservative. Output projects total ending balance, breaks down contributions vs compound growth, and applies the 4% safe withdrawal rule (Trinity Study) to estimate sustainable retirement income. The biggest freelancer retirement risk is income irregularity. Salaried workers contribute on autopilot via payroll deduction; freelancers must remember to contribute, which is psychologically harder during lean months. Best practice: set up automatic monthly transfers (e.g., $1,000/month to SEP-IRA) treated like a fixed bill rather than waiting for year-end. This smooths the income-variability problem and dramatically improves long-term outcomes. Most freelance financial advisors target 20% of gross income for retirement (higher than W-2 norms because no employer match). SEP-IRA vs Solo 401(k) decision: SEP is simpler (1-page IRS Form 5305-SEP setup, no annual filings until $250k+ balance), 25% of net SE income limit. Solo 401(k) allows higher total contribution ($23k employee + 25% employer = potentially $69k vs SEP's ~$40k for typical incomes), plus Roth option, plus loan provisions, but requires annual Form 5500-EZ filing after $250k balance. Use SEP for simplicity and lower income; Solo 401(k) for high earners who want to maximize tax-advantaged space or want Roth flexibility.
- 1Step 1 — Enter current age, target retirement age, and existing retirement savings
- 2Step 2 — Enter annual freelance income (use average over last 3 years to smooth irregularity)
- 3Step 3 — Set contribution percentage (10% minimum, 20% strong, 25% if SEP-IRA max)
- 4Step 4 — Set expected return (7% historical equity average, 5% conservative)
- 5Step 5 — Calculator applies future value formula: FV = P(1+r)^n + PMT × ((1+r)^n−1)/r
- 6Step 6 — Outputs projected balance, split into contributions vs growth from compounding
- 7Step 7 — Applies 4% safe withdrawal rate to estimate sustainable annual retirement income
30 years × $16k/yr contribution + compounding on $50k initial = $1.84M. 4% rule = $73k annual income, replacing 91% of $80k working income.
Possible but requires aggressive saving (25% of net SE income)
20 years gives less compounding runway — high contribution rate compensates partially. 4% rule yields 47% of working income replacement.
Aggressive Solo 401(k) max contribution + 20-year horizon hits FIRE target of $1.5M+.

SEP-IRA vs Solo 401(k) — which should I choose?
Solo 401(k) for high earners who want to maximize tax-advantaged space: $23k employee deferral + 25% employer-side, total up to $69k (2024), plus Roth option and loan provisions. SEP-IRA for simplicity: 1-page setup, 25% of net SE income cap (~$40k for typical incomes), no annual filings until $250k balance. Both are pre-tax; Solo 401(k) is the only one with Roth option.
How do I handle irregular freelance income?
Set up automatic monthly transfers to your retirement account treated as a fixed expense, sized to expected annual contribution ÷ 12. Use average of last 3 years' net SE income for the contribution percentage. Make a catch-up contribution at year-end if you had a strong year. The autopilot approach beats waiting for year-end every time.
What about Roth IRA?
Roth IRA has $7,000/year limit (2024, $8,000 if 50+) regardless of self-employment status, with income phase-out starting at $146k single / $230k married. Roth Solo 401(k) lets you contribute the $23,000 employee deferral as Roth at any income level — a major advantage for high-earning freelancers who want post-tax retirement income.
What return rate should I assume?
7% real return (after inflation) matches long-term S&P 500 average. 5% is conservative — accounts for elevated bond allocation or pessimistic forward returns. Don't assume 10%+ — that's optimistic survivorship-biased data. Use 5–7% for plans you must hit; 7–8% for stretch goals.
Does the 4% rule actually work?
The Trinity Study (1998) and subsequent analyses show 4% withdrawal of starting balance, adjusted annually for inflation, has near-100% success over 30-year retirements historically. Recent research suggests 3.5% may be safer for early retirees with 40+ year horizons, or those facing elevated valuations / lower forward returns. Use 4% as planning baseline; adjust down for safety margin.
Pro Tip
Set up automatic monthly transfers to your retirement account rather than waiting for year-end — eliminates the irregular-income hurdle and captures dollar-cost averaging benefits. Treat the contribution like a fixed bill paid before discretionary spending; freelancers who automate retirement savings beat those who manually contribute by 40–60% over a career.
