Target-date lifecycle glide paths
Enter assets, starting/terminal equity weights, annual stock/bond returns, contributions and rebalance costs.
Lifecycle portfolios reduce equity exposure and raise bonds as retirement approaches, balancing growth with risk around the retirement date. Glide paths differ; some reach their minimum equity allocation at retirement, while others continue declining afterward. A glide path does not guarantee capital; return sequence, inflation, human capital, withdrawals and fees matter.
Uses a five-year manual path; does not estimate long-term retirement safety, liabilities, human capital, withdrawals or taxes.

Start with a familiar situation, check the payoff, then test how the numbers change.
The idea · in two minutes
How does a gradual equity reduction compare with a static starting mix along an entered stock/bond return path?

The mechanics · payoff and exposure
w_{E,t}=w_{start}+(w_{end}-w_{start})t/T,\quad R_{p,t}=w_{E,t}R_{E,t}+(1-w_{E,t})R_{B,t}
Equity weight moves linearly to the endpoint each year; the comparator keeps the starting equity weight.
