Projection

See where every franc goes

Passive income exceeds annual contributions in Year 7 · June 2032–May 2033

Suggested routine: invest on the 5th of every month, or the next business day.

Coupon dates are issuance-specific, not universally January and July. The projection estimates each monthly purchase as a separate issuance with its first coupon six months later. Use the bond's NBR prospectus for its exact payment dates.

Model guide

Useful, transparent, intentionally conservative.

This planner models monthly contributions, partial Treasury bond auction allocation, and Aguka as the idle-cash parking layer. Coupons, unfilled bids, Aguka returns, and matured principal are pooled into future bid attempts.

01

Market price risk

Bond prices can fluctuate if sold before maturity.

02

Holding to maturity

Holding to maturity avoids market-price loss if the issuer pays as agreed.

03

Coupon and tenor

BK Capital states tenors of 3, 5, 7, 10, 15, 20 years and annual coupon rates from 10.65% to 13.5%, depending on the issuance.

04

Auction fill risk

The model defaults to 67% allocation based on the BNR historical sold/applied pattern, not 100% allocation.

05

Aguka idle cash

Unfilled bond money is modeled in Aguka at 10% tax-exempt annual return until it is used for another bid.

06

Secondary market

Buying or selling before maturity carries a 0.049% commission on turnover on each side, according to BK Capital.

07

This model is educational and does not guarantee future returns.
