Size debt service to a covenant · Fictional case

The situation

Downside CFADS is ₹72 crore and minimum DSCR is 1.30×. Scheduled interest would be ₹15 crore.

Your task

What debt service and principal fit the downside?

Reveal step-by-step solution
  1. Set up the problem

    Maximum service = ₹72 ÷ 1.30 ≈ ₹55.38 crore.

  2. Work through the numbers

    Principal component = ₹55.38 − ₹15 ≈ ₹40.38 crore.

  3. Interpret the result

    The annual principal ceiling is about ₹40.38 crore on the assumed interest. Check each period and solve the full schedule before sizing debt.

What to remember

Divide downside cash by minimum coverage, then model interest and principal over the full tenor.
