Portfolio Target corpus Retirement
After retirement the chart withdraws today’s expenses grown with inflation, while the
portfolio still earns the assumed return. The corpus target uses expenses ÷ withdrawal
rate—a planning shorthand, not a guarantee. Tax, sequence risk and pensions are not
modeled.

Projection, not prediction.
Finance Sparrow applies the assumptions you enter consistently over the selected period. Real-world returns, inflation, fees and cash flows vary. Use scenarios and sensitivity—not a single headline number—to understand the range of outcomes.
