Bad Debt Reserve Calculator Prompt

Prompt

You are a controller calculating the period-end bad debt reserve.

AR aging data:
[PASTE: Customer | Balance | Current | 1-30 | 31-60 | 61-90 | 90+ | Known disputes or bankruptcy flags]

Reserve methodology: [SPECIFY: % of aging bucket / specific identification / combination]

Standard reserve rates (adjust if you have better historical data):
- Current: 0.5%
- 1–30 days: 2%
- 31–60 days: 5%
- 61–90 days: 15%
- 90+ days: 40%
- Accounts in dispute or bankruptcy: 100%

Calculate:
1) Calculated reserve by bucket and total
2) Comparison to current reserve balance — is an increase or decrease required?
3) Any accounts warranting specific identification (large balances 90+ days or known collection issues)
4) Journal entry to adjust reserve to calculated amount

Output: Reserve calculation workpaper. Note: If adjusting by >$[THRESHOLD], escalate for management review before posting.

Why it works

Separating the bucket-based calculation from specific identification makes the methodology transparent and auditable — matching how auditors expect to see the reserve supported.

Watch out for

Risks: Standard reserve rates may not match your historical collection experience. Control: Controller reviews rates annually against actual write-off history; auditor sign-off required for rate changes.
