The following tool compares Current Interest Bonds (CIBs) with Capital Appreciation Bonds (CABs):

It requires the total assessed valuation for the school district and your individual assessed valuation as an inputs.

It also requires the bond amount(s), the interest rates, the life of the bonds and the first year of taxation for the CAB as inputs.

These inputs are in yellow.

The first calculated field is the repayment multiplier (a.k.a. repayment ratio) for each bond type. This value is based on certain assumptions that are annotated at the bottom of the calculator. If your bond consultant is using a different scenario (e.g. level total tax) and has produced a more accurate repayment ratio, you can override the calculated value with this more accurate value.

The "Total Tax" is also the total repayments (principal and interest) being made to the bond investors over the life of the bond.

The "comparable interest rate" for the CAB can be used as an input for the CIB interest rate and as long as all other inputs are the same will produce the same Total Tax for the CIB as the CAB.

The green part of the results relate to "Portion of the Total Taxes" and is per the year of the assessed valuation.

Most of this valuation will grow at the rate limited by Prop 13. However many people will sell their home during the life of the bond and this will often result in a significant increase in the total assessed valuation for the school district. This calculator does not distinguish (or allow discrimination of) tax liabilities for current homeowners versus new residents moving in during the life of the bond. The reported tax liability per $100,000 should be considered the average liability for that portion of your property, not the tax liability for a specific homeowner. Homeowners that stay for the duration of the bond will have a lower tax liability and newcomers will typically have a higher tax liability.

The blue part of the results relate to annual tax liabilities which are regulated in California law and are another metric for the "affordability" of the bonds.
