How the Math Works
When you invest $2,000 every month, two things grow your balance: your contributions and compound interest on everything already invested.
The Formula
n = log(1 + target × r / contribution) / log(1 + r)
where r = annual return / 12 (monthly rate), n = months
Over 16.61 years, you personally contribute $398,640. The remaining $351,360 comes from compound growth — meaning compound interest delivers 1.9x your total contributions toward the final $750k target.
What Happens After You Hit $750k?
Once you reach $750k, you have choices depending on your retirement goal.
If $750k is your retirement number
You can stop working and withdraw from the portfolio. At a 4% withdrawal rate, $750k generates $2,500/month indefinitely.
If $750k is your Coast FIRE number
You can stop contributing entirely and let compound growth carry your portfolio to your larger retirement target. You still work to cover living expenses — but saving for retirement becomes optional.

Frequently Asked Questions
Does this include money already saved? +
No — the timeline above starts from $0. If you already have savings, you'll reach $750k faster. The compound interest calculator lets you enter a starting balance and shows the adjusted timeline.
What return rate should I use? +
The S&P 500 has historically returned around 10% annually before inflation, or roughly 7% in real (inflation-adjusted) terms. Most long-term financial planning uses 6–8% nominal return for diversified index fund portfolios. The 7% baseline used here is a reasonable middle ground. Conservative planners use 6%; aggressive planners use 8–9%.
Is $2,000/month realistic? +
Investing $2,000/month represents a significant commitment typically requiring a above-median income or high savings rate. As a rule of thumb, financial planners often suggest targeting 15–20% of gross income for retirement savings.
What if I increase contributions over time? +
Even small annual increases significantly reduce the timeline. A 3% annual increase in contributions — matching a typical salary raise — can cut years off the timeline. The compound interest calculator has an annual contribution increase slider to model exactly this.
