How This Calculator Works
Shows how far rising building costs may have pushed today’s rebuild cost above the dwelling limit you set years ago.
The formula
- Today’s rebuild cost = original dwelling limit × (1 + annual inflation rate)years
- Shortfall = today’s rebuild cost − original limit
- Coverage deficit = shortfall ÷ today’s rebuild cost
Assumptions and limits
- You choose the inflation rate; the 4.5% a year default is our assumption. Construction costs can move very differently from general consumer prices, and from one region to another.
- Assumes your original limit matched the full rebuild cost when it was set, and that the policy has no automatic inflation-guard increase.

Frequently Asked Questions: Insurance Inflation Calculator
Expert mathematical answers, formula explanations, and related comparison guides.
Why does inflation erode fixed death benefits and disability income?
Fixed-dollar insurance payouts do not adjust upward automatically unless you purchase an explicit Cost-of-Living Adjustment (COLA) rider. An inflation rate of 3% erodes over 40% of real purchasing power in 18 years. Check your required death benefit with the Life Insurance Needs Calculator.
How do property insurance policies protect against construction cost inflation?
Quality property policies include an Inflation Guard Endorsement that automatically adjusts dwelling limits quarterly according to local construction cost indices. Read our guide on What is an Insurance Endorsement?.
How can I protect my income against long-term disability inflation?
When purchasing individual disability coverage, always request a compound COLA rider that indexes your monthly benefit to the Consumer Price Index once you are on claim. Learn more in our Disability Insurance Architecture Guide.
