A ladder spreads fixed income across staggered maturities so something is always close to cash and reinvestment risk is spread out. The app models it, you buy it at your broker, and imports keep it tracked.
- On Fixed Income → Builder, set the total amount, number of rungs, and spacing. Pick T-bills or brokered CDs (CDs add a spread over the Treasury curve). Rungs are priced off the live par-yield curve, so the blended yield and income figures are current. The income card reads steady state, meaning what the ladder pays once every rung has been rolled out to the longest tenor, and names the smaller first-year figure beneath it, because a ladder being built today still holds short rungs at short rates.
- Sizing to a plan? Use Size to model target. It computes the dollars your model's ladder slice calls for at your portfolio value.
- Save the plan. It's a shopping list, not an order. The app never trades. Buy the rungs at your broker at their auction/offer.
- Import the broker CSV afterward (how). Each bill/CD is recovered with its terms and starts accruing on the Performance tab; Ladder & maturities shows the rungs, projected income, and FDIC exposure per issuer.
- In your model, open the fixed-income slice's Details… drawer and set its Slice type to T-bill/CD ladder. Every held instrument then counts toward it automatically, so rebalancing treats the ladder as one sleeve and rolling a rung never breaks the model.
When a rung matures, the proceeds land in core cash. The Rebalancing page's Deploy row will show them ready to reinvest.
