Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Ageing allowance to answer this question: estimate expected credit losses across current, overdue and seriously overdue receivables? Enter Current receivables, 1–60 days overdue, More than 60 days overdue, and 3 other inputs; the calculator shows Required allowance. Try changing one number and watch what happens to Required allowance. The answer tells you Required allowance.
Age 15Explain it to a 15-year-oldConnect it to the formula
Ageing applies higher expected-loss rates as invoices become older and generally harder to collect. The rule is Allowance = current × rate 1 + overdue × rate 2 + old overdue × rate 3. Its input values are Current receivables, 1–60 days overdue, More than 60 days overdue, Current loss rate (%), 1–60 day loss rate (%), 60+ day loss rate (%), and the main result is Required allowance. Try changing one number and watch what happens to Required allowance.
CollegeExplain it at college levelState the model precisely
This calculator evaluates one accounting relationship within a consistent entity, currency, reporting period and recognition policy. The implemented relation is Allowance = current × rate 1 + overdue × rate 2 + old overdue × rate 3, evaluated from Current receivables, 1–60 days overdue, More than 60 days overdue, Current loss rate (%), 1–60 day loss rate (%), 60+ day loss rate (%) to produce Required allowance. Ageing applies higher expected-loss rates as invoices become older and generally harder to collect. Recognition, measurement, tax, consolidation, foreign-currency and disclosure rules may require adjustments under the accounting framework that applies to the entity.
