Self-Employment Tax Calculator: Federal and State Combined for 2026
Most self-employed workers underpay by thousands because they calculate federal SE tax without accounting for state-level obligations running parallel to it. The combined burden in high-tax states can push your effective marginal rate past 50%. Running both numbers together before quarterly deadlines is the only way to avoid a penalty-laden surprise in April.

Self-Employment Tax Deduction Calculator: Keep More of What You Earn
Most self-employed workers overpay federal income tax by miscalculating the SE tax deduction. The IRS allows you to deduct exactly half of your self-employment tax from gross income, but the math is circular and most people get it wrong. Run the numbers correctly and you recover real money.
Will Your Retirement Savings Last? Running a Longevity Stress Test
Most retirement plans are built to age 85. The average 65-year-old woman today has a 50% chance of reaching 88. Running your savings against realistic longevity scenarios reveals whether you have a funding gap before it becomes a crisis.

Do Retirement Calculators Include Social Security? What You're Actually Calculating
Most retirement calculators give you a savings target that ignores $300,000 or more in guaranteed lifetime income. You may be over-saving into taxable accounts while under-optimizing your claiming strategy. The gap between what you calculate and what you'll actually need can reshape your entire retirement timeline.

Monte Carlo Retirement Calculator: When Probability Analysis Beats Deterministic Models

Retirement Planning for Married Couples: Coordinating Accounts, Social Security, and Survivor Benefits
Most married couples plan for retirement as two separate individuals. That mistake can cost six figures in lifetime Social Security income alone. Coordinating accounts, claiming ages, and survivor benefits changes the math entirely.
Retirement Income Calculator By State: Which States Let You Keep More of Your Retirement Money
Where you retire determines how much of your retirement income you actually keep. State taxes on Social Security, pensions, and IRA withdrawals vary wildly, and most retirees never calculate the difference before moving. The gap between the best and worst states can exceed $500,000 over a 25-year retirement.
How to Calculate Alimony Payment Amount by State
Most people guess at alimony. Courts don't. The formula varies by state, by income, and by marriage length, and getting it wrong costs thousands. Here is how to calculate what you actually owe or are owed.

Retirement Planning With Inflation: How Price Growth Quietly Destroys Your Savings
Most retirement projections show a large number at the end. That number is almost certainly wrong. Ignoring inflation means planning to run out of money before you run out of time.
Retirement Income Calculator After Tax: What You Actually Spend vs What You Withdraw
Most retirees calculate how much they need to withdraw. Few calculate how much they keep. The gap between your gross withdrawal and your after-tax spending money costs some households more than $8,000 per year in avoidable over-withdrawal. Run the right number first.
Retirement Income Calculator With Social Security: Timing Your Claim for Maximum Lifetime Benefits
Most retirees claim Social Security at the wrong age and leave six figures on the table. The break-even math is not complicated, but almost nobody runs it before filing. Your claiming age is the single highest-leverage decision in your entire retirement income plan.

Debt Payoff vs. Investing: The Math That Decides For You

Investment Return Calculator: Real Estate vs Stocks vs Bonds
Most investors compare asset classes by headline returns and get the wrong answer. Fees, taxes, and time destroy the gap between a 10% stock return and an 8% real estate return. The math tells a different story than the narrative.

Real Compound Interest: Calculate Your After-Inflation Growth Rate
Most investors track nominal returns and call it progress. Inflation has already eaten a portion of that number. The real compound growth rate tells you what your money actually earned, and it's almost always smaller than you think.

Compound Interest With Monthly Investments: How Much You'll Have in 10, 20, and 30 Years
Most investors underestimate what consistent monthly contributions actually produce over time. The gap between a $300 monthly investment and a $500 monthly investment at 30 years is not $72,000. It's over $200,000. The math is working for you or against you right now.

How to Calculate XIRR for Investments With Irregular Cash Flows
Standard IRR assumes your cash flows arrive at perfectly equal intervals. Real investments never work that way. XIRR fixes that, and the difference in your calculated return can exceed 3 percentage points on a typical portfolio.
Current Dividend Yield vs Trailing Yield: You're Probably Using the Wrong Number
Most investors quote dividend yield from a screenshot, not a calculation. That single habit distorts income projections by hundreds of dollars per year. Current yield and trailing yield measure different things, and confusing them changes every decision you make about income-generating holdings.
