Formula & Mathematical Methodology: Seller Financing Balloon Note Formula

PMT = P × r(1+r)N(1+r)N − 1
BalloonBalancek = P × (1+r)N − (1+r)k(1+r)N − 1
PMT = P × [r(1+r)^N]/[(1+r)^N − 1]; BalloonBalance_k = P × [(1+r)^N − (1+r)^k] / [(1+r)^N − 1]

Worked Example: Benchmark Scenario: Seller Financing Balloon Note

Compute monthly P&I, interest earned by seller, and exact balloon payoff balance at maturity.

  1. Enter your financial, equity compensation, or tax parameters.
  2. Evaluate the governing equation: PMT = P × [r(1+r)^N]/[(1+r)^N − 1]; BalloonBalance_k = P × [(1+r)^N − (1+r)^k] / [(1+r)^N − 1].
  3. Review the primary result, supporting metrics, and 3 interactive SVG charts.
Result: Computes Seller Financing Balloon Note via PMT = P × [r(1+r)^N]/[(1+r)^N − 1]; BalloonBalance_k = P × [(1+r)^N − (1+r)^k] / [(1+r)^N − 1].
