How to Use This Calculator
  1. Enter cumulative paid losses at each development age for each accident year.
  2. The calculator computes age-to-age development factors from the triangle data.
  3. Review the selected link ratios and the tail factor.
  4. Apply the factors to the most recent diagonal to project ultimate losses.
  5. Compare ultimates from the weighted average and volume-weighted methods.
