Maintenance Fee Inflation Calculator
Most travel club and timeshare buyers focus on the upfront price and underestimate how recurring fees grow. This tool projects how a starting maintenance fee compounds over 5, 10, or 20+ years and shows the all-in cost against an inflation benchmark.

How this calculator works
Formulas and assumptions
Year-by-year fee: annual_fee_t = starting_fee × (1 + rate)^(t − 1).
Total maintenance fees sum every year over your horizon.
Expected special assessments = probability × average amount × horizon (when both provided).
Inflation benchmark recomputes the same fee schedule at a slower benchmark rate (default 3%) and shows the excess.
Present value of fee stream discounts each year at your specified discount rate.
Hidden-cost flag bands:
- Contained: total maintenance fees < 50% of upfront price, or no upfront price entered and growth multiple < 1.4.
- Meaningful: 50–99% of upfront price, or growth multiple 1.4–1.99.
- Heavy: 100–199% of upfront price, or growth multiple 2.0–2.99.
- Budget-breaking: 200%+ of upfront price, or growth multiple 3.0+.
Frequently asked questions
Why do maintenance fees grow over time?
Maintenance fees fund property upkeep, taxes, utilities, and management costs that rise with general inflation, labor costs, and property aging. Most contracts allow annual increases at the resort or club's discretion.
Are special assessments included?
Only if you provide both a probability and an average amount. Real-world special assessments are irregular, so the calculator treats them as an expected-value scenario, not a guaranteed cost.
What is present value?
Present value (PV) discounts future dollars to today's terms. A $2,000 fee paid in 10 years is worth less in today's dollars than $2,000 paid today, because money has earning power over time.
How far into the future should I model fees?
Most buyers find 10 years a useful planning window. Beyond 20 years, projections become highly assumption-sensitive. Comparing 5, 10, and 15 year horizons can highlight how much is hidden in the long tail.
What if my fee history shows bigger jumps?
Use the largest plausible annual increase you've personally seen or read about for the program. Rates above 8% are aggressive — the calculator will flag that scenario.
