Key Assumptions for Retirement Corpus Planning
Accurate retirement planning depends on realistic assumptions about inflation, returns, lifestyle changes, and healthcare costs.
What Assumptions Should You Use For Retirement Planning?
Use conservative assumptions: 5–7% inflation, 6–10% long-term investment returns, and 20–30 years retirement duration.
Core Retirement Planning Assumptions
Typically assumed between 5%–7% depending on country and economic conditions.
Long-term returns usually estimated at 6%–10% for diversified portfolios.
Most plans assume 20–30 years of post-retirement life.
Medical expenses increase with age and must be factored into long-term planning.
Small Changes In Assumptions Can Change Your Corpus Significantly
Even a 1–2% difference in inflation or returns can change your retirement corpus by lakhs or thousands of dollars over time.

How Lifestyle Impacts Your Retirement Corpus
Your retirement corpus is directly influenced by your lifestyle choice, location, healthcare needs, and spending habits.
Does Lifestyle Affect Retirement Corpus?

Retirement Lifestyle Comparison
| Lifestyle Type | Monthly Cost | Corpus Requirement | Description |
|---|---|---|---|
| Basic | $800 – $1500 | Low | Simple living with essential expenses only |
| Comfortable | $1500 – $3000 | Medium | Balanced lifestyle with travel and healthcare |
| Luxury | $3000+ | High | Premium living with global travel and comfort |
Lifestyle Inflation Is One Of The Biggest Retirement Risks
