Calculator

Government and nonprofit teams do unique work – work that, often, requires unique tools. We believe that, in order to unlock strategic treasury initiatives, public finance teams need better software than Excel spreadsheets. That very need is at the heart of why we started DebtBook.

In that same spirit, we wanted to offer a tax-exempt debt service calculator, designed to give your team a rough idea of what your required proceeds would cost for, as an example, a capital project. Below, you can enter your inputs to see your calculated average annual debt service.

And, as always, if you want to learn how DebtBook can help streamline your debt management workflows, reach out for a demo.

Assumptions

This calculator should provide an estimate – but not an exact calculation. Because the calculator does not contain a full bond sizing model, it will not return an exact amount, but we believe in most instances should come within $5K annually. Additionally, this calculator assumes all bonds are priced at par and interest is paid semi-annually.

Definitions

Level Debt

Level Debt is a structure where you will pay roughly the same amount of debt service (principal + interest) in each period throughout the life of the issue.

Level Principal

Level Principal is a structure where your principal payments will stay roughly the same in each period throughout the life of the issue.
