Vendor Inflation Calculator
Vendor contracts inflate at different rates. This calculator computes a weighted average.
Weighted inflation %
9.04%
Annual dollar increase
$17,905
New total cost
$215,905
How the math works
Weighted = sum(cost × inflation) ÷ sum(cost). Useful for opex budget modeling.
Stagger vendor contract renewals across calendar quarters. Concentrated annual renewal forces decisions during a single narrow window — staggered renewals let you learn pricing trends in Q1 and apply that intel to Q3 negotiations.
How to Use
- Enter landscaping cost and inflation %.
- Enter janitorial cost and inflation %.
- Enter security cost and inflation %.
- Enter pool/amenity cost and inflation %.
- Read weighted inflation and dollar increase.
Frequently Asked Questions
2022-2024 context?
Landscaping/janitorial: 8-15% (labor-driven). Security: 6-12%. Pool: 5-10%. Pest: 4-8%. Trash: 3-7%. Vendors passed through labor and minimum wage hikes aggressively.
Negotiation tactics?
Lock multi-year contracts with fixed escalators (3-5% annual). Pre-pay for annual discount (5-8%). Bid out every 2-3 years. Consolidate to one vendor for volume discount. Each saves 5-15% on eventual bill.
Red flags?
Vendor asks for mid-contract adjustment: possibly priced loss-leader. Above-15% annual increase signals market out of line. Sudden service quality drop accompanying price request: terminate and rebid, don't accept both at once.
How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
