Retirement Savings Calculator: How Much to Save Monthly in 2026

Enter your retirement goal, current savings, age, and expected returns — get instant monthly savings target, inflation-adjusted growth projection, and visual timeline to retirement.

How This Retirement Calculator Works (2026 Update)

It solves for the monthly contribution needed using the future value of an annuity formula, adjusted for inflation:

FV = Current × (1 + real_rate)^periods + Monthly × [((1 + real_rate)^periods - 1) / real_rate]

Where real_rate = (nominal return - inflation) / compounding periods.

How to Set a Realistic Retirement Goal in 2026

Use the 25× rule as a starting point, then adjust:

Example: Want $60,000/year in today’s dollars? → Goal ≈ $1.5M (25×) minus ~$300k present value of Social Security → target ~$1.2M from savings.

Common Retirement Planning Mistakes to Avoid

Frequently Asked Questions – Retirement Savings 2026

Is the 4% rule still valid in 2026?

Yes, still a solid benchmark per major firms (Vanguard, Fidelity), but many suggest 3.5–3.8% for longer retirements or lower bond yields. Test different withdrawal rates in the calculator.

What return rate is realistic?

7% nominal (~4% real after inflation) for balanced portfolios — matches long-term data. Use 5% for safety, 8–10% only if aggressive and young.

Does this include Social Security or pensions?

No — this is personal savings only. Subtract expected benefits (check ssa.gov) from your annual need to lower the goal.

How does inflation affect my plan?

At 3%, $1M today needs ~$2.43M in 30 years to keep same purchasing power. The calculator uses real returns to adjust automatically.

Should I use pre-tax or after-tax numbers?

Use after-tax spending goal. Traditional 401(k)/IRA withdrawals are taxed; Roth are tax-free. Adjust goal up 15–30% if using pre-tax accounts.
