Retirement Planning Guide: 401k, Roth IRA, Social Security & Pension Calculators

Retirement planning is the intersection of long-term saving, tax optimization, and income strategy. Getting it right can mean hundreds of thousands of dollars more in after-tax lifetime wealth. This hub covers everything from contribution limits to withdrawal sequencing — with calculators to model every decision.

The Retirement Account Landscape

Tax-Deferred Accounts (Traditional 401k, IRA, SEP-IRA)

Contributions reduce your taxable income today. Investments grow tax-deferred. Withdrawals in retirement are taxed as ordinary income. Required Minimum Distributions (RMDs) begin at age 73.

Best for: People who expect to be in a lower tax bracket in retirement than today.

Tax-Free Accounts (Roth 401k, Roth IRA)

Contributions are made with after-tax dollars. Investments grow tax-free. Qualified withdrawals are completely tax-free with no RMDs.

Best for: People in lower tax brackets today, young investors with long time horizons, and those planning large Roth conversions.

Self-Employed Accounts (Solo 401k, SEP-IRA)

Self-employed individuals can contribute much more than employees — up to $69,000 in a Solo 401(k) via both employee and employer contributions. This is one of the most powerful tax reduction tools for freelancers and business owners.

Roth Conversion Strategy

Converting traditional IRA/401(k) funds to Roth during low-income years (early retirement, career breaks, or years with large deductions) can save hundreds of thousands in lifetime taxes. The key is filling your current tax bracket without pushing into the next one.

The Roth conversion ladder allows early retirees to access Roth funds penalty-free 5 years after conversion — a critical strategy for retiring before age 59½.

The decision of when to claim Social Security is one of the most impactful financial choices in retirement:

Claiming at 62: Permanent reduction of ~25–30% from your full benefit
Claiming at Full Retirement Age (67 for most): 100% of your earned benefit
Delaying to 70: Benefit increases 8% per year — a guaranteed return unmatched in any other asset

For married couples, coordinating spousal and survivor benefits adds additional complexity and opportunity.

Division 296 (Australia)

From July 1, 2025, Australians with superannuation balances above $3 million face an additional 15% tax on earnings attributable to the excess — bringing the effective rate to 30%. Proactive planning (pension rebalancing, downsizing strategies, withdrawal sequencing) can significantly reduce this liability.

Key Retirement Planning Strategies

Max out employer match first — this is a 50–100% instant return
Fill Roth during low-income years — conversions at 12% beat distributions at 22%
Delay Social Security if possible — delaying from 67 to 70 adds ~24% to your benefit permanently
Plan for RMDs early — large traditional IRAs trigger forced income that can push you into higher brackets
Sequence of returns matters — holding 1–2 years of expenses in cash protects against sequence risk in early retirement
