Fund the life you want.
Retirement models, Monte Carlo scenarios, and sequence-of-returns stress testing help you understand whether your savings rate, allocation, and withdrawal plan survive a bad first decade—not just an average one.
Two retirees can earn identical average returns over 30 years and end up in completely different places. What separates them is when the bad years arrive. A market drop in your first few years of withdrawals does permanent damage, because you sell shares into weakness to fund living expenses—and those shares never recover.
That is sequence-of-returns risk, and it is the single most underestimated threat to a retirement plan. QuantRidge models contributions, growth assumptions, and withdrawal sequences across 401(k), IRA, taxable, and Roth accounts, then stress-tests them against exactly this scenario.
Retirement tools connect to your broader wealth picture: cash flow surplus, tax-efficient withdrawal order, and legacy goals all inform the same projection engine.

Age 67 · $2.1M target
Average returns hide the danger. Run your plan against a poor first decade of retirement and see whether your withdrawal rate still holds—or whether the portfolio depletes a decade early. This is the scenario that quietly ends retirements, and it is the one most spreadsheets never test.
Retirement
Sequence-of-returns risk, made visible
The "4% rule" was derived from specific historical conditions and a specific portfolio. Your spending, allocation, time horizon, and other income sources are different. Model your own sustainable withdrawal rate and see how it moves when you change retirement age, allocation, or spending.
Retirement
Know your safe withdrawal rate—yours, not a rule of thumb
Holding one to three years of expenses in stable assets means you are not forced to sell equities during a drawdown. Model how a cash buffer changes your depletion risk—and what it costs you in expected return during good years.
Retirement
Cash reserves and the buffer strategy
Start with annual spending goals, expected Social Security, and other income sources. Layer portfolio withdrawals and test whether your current savings rate closes the gap—or leaves a shortfall you can address now.
Retirement
Project income needs with real numbers
Roth vs traditional balances, RMD timing, and taxable account sequencing all affect after-tax retirement income. Models help you visualize tradeoffs without memorizing every IRS rule.

It is the risk that poor market returns arrive early in retirement, while you are withdrawing. Selling shares during a drawdown to fund living expenses permanently removes them from the portfolio, so the same average return produces a far worse outcome than if the bad years came later. It is the primary reason two retirees with identical average returns can end up in very different places.
No. QuantRidge provides projection software. Complex planning may still benefit from a qualified professional.
Return rates, inflation, contribution amounts, retirement age, and withdrawal rates among others.
It depends entirely on your allocation, time horizon, spending flexibility, and when you retire. The 4% guideline came from specific historical data and a specific portfolio mix. Rather than assuming it applies, model your own withdrawal rate against stress scenarios and see where it breaks.
You can layer estimated benefits into income projections; exact SSA amounts should be verified at ssa.gov.
