| Scenario | Claim | Days Late | Method | Key Inputs | Penalty (Approx.) |
|---|---|---|---|---|---|
| Vendor invoice | 100,000 | 10 | Daily % (simple) | 0.25% / day | ~2,500 |

Formula Used
- claim base: base = claim
- net base: base = max(0, claim − deductible)
- Daily simple: (min(base×r, per_day_cap)) × effective_late
- Daily compound: base×((1+r)^effective_late − 1)
- Monthly simple: base×r×(effective_late / days_in_month)
- Daily % + fee: (min(base×r, per_day_cap)+daily_fee) × effective_late
- Tiered daily: sum of (min(base×tier_rate, per_day_cap) × tier_days)
- Flat fee: flat_fee
- penalty_base = max(penalty_base, min_penalty)
- % cap: penalty_base ≤ base×cap_percent/100
- amount cap: penalty_base ≤ cap_amount (if set)
- tax = penalty_base×tax_percent/100 (optional)
- total_penalty = penalty_base + tax + admin_fee (optional)
- total_payable = claim + total_penalty

Insights
Penalty drivers and sensitivity
Late-claim penalties are shaped by base amount, effective late days, and the selected method. Effective late days equals days late minus grace days, never below zero. For daily methods, each 0.10% of rate adds roughly 100 per day on a 100,000 base. Increasing a grace period from 0 to 3 days cuts chargeable time by 3 days.
Method selection for policy alignment
Daily simple grows linearly and is easy to audit. Daily compound accelerates growth and fits interest-like clauses, so the gap versus simple becomes more visible after two to three weeks. Monthly simple prorates delays using days-in-month, which is useful when policies quote monthly rates. Flat fee works for fixed administrative penalties.
Tiered and mixed structures
Tiered daily rates model escalation: a lower tier for early lateness and higher tiers for prolonged delays. For example, a policy might apply 0.10% for the first 7 days, 0.20% through day 23, and 0.35% thereafter, which changes the slope of the penalty curve. Mixed “daily percent plus daily fee” combines a proportional charge with a fixed per-day component to reflect both financing cost and processing workload.
Controls that reduce dispute risk
Caps stabilize outcomes. A percent cap limits penalty base to a share of the chosen base amount, while an absolute cap enforces a hard maximum. A per-day cap limits daily increments in percent methods and can prevent outliers on large claims. Net base mode subtracts a deductible, aligning penalties with payable exposure rather than the gross claim figure. A waiver threshold can set the penalty base to zero for small claims.
Reporting, forecasting, and operational use
Exportable records reduce reconciliation time. CSV output preserves inputs and computed fields for audit trails, while the PDF summary supports approvals and vendor communication. The Plotly trend graph visualizes penalty accumulation across days late, helping teams compare scenarios, set reminders before higher tiers start, and forecast the cost of delayed submission. Date-based counting with weekend exclusion supports contracts that define business-day timelines.
FAQs
1) What is “effective late days” in the results?
It is days late minus grace days, never below zero. Penalties apply only after the grace period ends, which protects minor delays from charges.
2) When should I use daily compound instead of daily simple?
Use compounding when policies explicitly require compounding or interest-style growth. If the policy is silent, daily simple is usually easier to explain and audit.
3) What does the per-day cap do?
It limits the maximum daily increment from percentage methods. This helps control large-claim exposure and keeps daily charges consistent with internal or regulatory limits.
4) How does the waiver threshold work?
If the base amount is at or below the threshold, the penalty base becomes zero. Optional admin fees can still be included, while tax is applied only to penalty.
5) Why use net base mode with a deductible?
Net base calculates penalties on claim minus deductible. This aligns the penalty with the payable portion and reduces disputes when deductibles materially affect settlement.
6) Does tax apply to the whole payable amount?
No. This calculator applies tax only to the penalty base, not to the claim amount. If your rules tax the total, adjust the tax formula accordingly.
