Exclusions and checks required

  • Annual compounding and a constant rate are assumed; tax, fees, and cash flows are excluded.
  • The current form names the amount field principal while execution reads principalMan, a known mismatch that can make the amount result invalid.
  • The screen is designed around a ten-thousand-yen unit, but this content update does not repair the field mismatch.

Example input:：A principal of 100 (ten-thousand-yen units) at 3% for 20 years
