nmtc-calc 0.2.0

Python calculator for New Markets Tax Credit (NMTC) leveraged transactions

nmtc-calc 🏗️

Python calculator for New Markets Tax Credit (NMTC) leveraged transactions.

Built for CDFI practitioners, CDEs, tax credit investors, and project sponsors who need reproducible, auditable NMTC deal math — without starting from scratch in Excel.

---

Why nmtc-calc?

New Markets Tax Credit transactions involve complex layered capital structures — QEIs, QLICIs, leverage loans, 7-year credit schedules, investor IRR, and net subsidy calculations. Every practitioner builds these models from scratch in Excel. nmtc-calc standardizes and automates the math.

• QEI: Qualified Equity Investment into the CDE
• QLICI: Qualified Low-Income Community Investment (loans to QALICB)
• QALICB: Qualified Active Low-Income Community Business (project borrower)
• CDE: Community Development Entity (allocatee of NMTC authority)
• A Loan: Senior QLICI mirroring the leverage loan
• B Loan: Subordinate QLICI, typically forgiven at year 7
• Credit Price: dollars per dollar of NMTC benefit (typically 0.70-0.85)
