Retirement Savings Calculator
Savings rate and time are the levers most households control outright. This view emphasizes accumulation: how contributions and growth combine into the balance you will need later, before you translate that balance into retirement spending.
Quick answer
Enter current savings, ongoing contributions (with growth if applicable), and return assumptions. You will see trajectory toward the portfolio implied by your retirement spending goal — and where shortfalls appear early enough to fix.

How to use this calculator
- Automate before you optimize: A steady contribution beats a perfect allocation you never fund.
- Anchor ages and horizon: Current age, retirement age, and how long the portfolio must fund spending drive every output.
- Separate real from nominal: Inflation pairs with spending growth; real return pairs with long-run sustainability.
- Use Advanced mode when taxes differ by account: Roth, traditional, and taxable buckets change spendable cash even when totals look equal.
What moves the savings curve
Contribution amount, escalation, fees, and real return assumptions dominate. Volatility matters more through timing near retirement than in early accumulation.

Nominal balance vs purchasing power
A large balance with high future spending may still be insufficient in real terms — pair balances with inflation and spending.
Real-world example
- Example: 1% fee drag: Small fee differences compound into meaningful gaps at retirement — the sensitivity views help show whether fee reduction is worth the hassle (illustrative).

What to change first
If you are behind, raising savings rate and delaying large fixed spending commitments usually beat chasing return in the model.
FAQ
Is readiness a guarantee?
No. It is a modeled score from your inputs. Use it to prioritize savings, timeline, and spending tradeoffs.
Should I trust one Monte Carlo run?
Use it as a stress lens. If success is high but fragile to small return cuts, widen your cushion.
Does this replace personalized advice?
