When can you stop saving for retirement?

“When can I stop saving for retirement?” is not the same as “when can I retire?” The Coast FIRE framing is usually the right one: you have enough invested that, if it compounds at an assumed real return until a traditional retirement age, it should reach a full FIRE target without further contributions — while you still earn enough to cover current spending.

Precise definition

• Full FIRE number ≈ annual spending ÷ planned withdrawal rate.
• Coast number ≈ full FIRE ÷ (1 + r)^n, n = years until traditional retirement age.
• You are “coasting” (under the model) when current portfolio ≥ coast number.
• You still need earned income (or other cash flow) for today’s lifestyle unless you are fully FI.

What “stop saving” should mean in practice

Stopping aggressive retirement contributions is not the same as zero savings forever. Many people keep a floor: emergency fund top-ups, employer match (often still free money), HSA contributions, or a small default investment habit to fight lifestyle creep. “Stop saving” is better phrased as “stop prioritizing max retirement savings over other life goals under these assumptions.”

Worked example

Spend $80k/year, plan 4% SWR → FIRE $2.0M. Age 38, traditional age 65 → n = 27 years. At 5% real, coast ≈ $2.0M / (1.05)^27 ≈ $534k. If you hold $600k invested (and healthcare/debt are handled), the constant-return model says you can reduce retirement contributions. If you hold $400k, you are not there yet — save more, spend less, or accept a later traditional age.

Decision gates before you cut contributions

• Surplus still exists at a lower real return (e.g. −1 pp) and a stricter SWR.
• Sequence stress test tails are acceptable for your risk tolerance (Coast free stress test).
• Healthcare and emergency funds are not “inside” the coast pile.
• You will not silently raise spending enough to re-inflate full FIRE.
• Partner alignment if household finances are shared.
• You re-run the numbers on job change, housing, kids, or market regime shifts.

Coast vs Barista vs full FI

• Coast: stop (or reduce) retirement contributions; still work for living expenses.
• Barista / semi-retirement: portfolio covers part of spend; part-time income covers the rest.
• Full FI: portfolio covers spending at your planned withdrawal rate without required work income.

Why people regret stopping too early

• Optimistic return or SWR assumptions that reverse under stress.
• Lifestyle creep after “I’m coasting” identity.
• Healthcare costs and family changes not in the spreadsheet.
• Confusing Coast with early retirement and withdrawing too soon.

FAQ

• Should I always take the employer match after coasting? Often yes — it is usually a high risk-adjusted return — but this is not personalized advice.
• Can I coast at 40 with a 50-year horizon? Full FIRE for early withdrawal is a different problem; coast-to-65 is not early retirement math.
• Is there one universal age to stop saving? No — only assumptions + pile + spending + gates.
