A good software salary can accelerate financial independence. But long hours, layoffs and burnout raise an important question: how much money would you need before work becomes optional?
Why 25× expenses may not be enough
The traditional FIRE formula is simple:
FIRE corpus = Annual expenses × 25
It comes from the 4% withdrawal rule. However, that rule originated in the US. FinPlann's India retirement guide explains why Indian inflation, healthcare costs and longer retirements call for more conservative planning. Its guide indicates roughly 26× expenses for retirement at 60 and 30× at 55, with higher multiples for earlier retirement.
Three developer scenarios
I used the FinPlann FIRE calculator to compare three illustrative profiles:
- Bengaluru engineer: ₹25 LPA salary, ₹80,000 monthly spending, ₹20 lakh invested and ₹9 lakh invested annually. Calculator result: FIRE number - 2,88,00,000 and Estimated Time - 20 Years.
- US-based NRI: Planning to retire in India, with ₹2 lakh monthly spending, ₹1 crore invested and ₹30 lakh invested annually. Calculator result: FIRE number - 7,20,00,000 and Estimated Time - 15 Years.
- Freelancer: ₹60,000 monthly spending, ₹10 lakh invested and ₹3.6 lakh invested annually. Calculator result: FIRE number - 2,160,00,000 and Estimated Time - 30 Years.
These are assumptions, not predictions. Spending is the starting point not the salary.
Don't ignore the hidden costs
Healthcare, lifestyle inflation and currency movements can derail an otherwise sensible plan. NRIs should also consider where they'll retire and which currency will fund their expenses.
What would change your FIRE target most: lower spending, higher savings or retiring later?

I checked the three targets against the 30x rule. 80,000 x 12 x 30 = 2.88 crore and 2 lakh x 12 x 30 = 7.2 crore both match. The freelancer is 60,000 x 12 x 30 = 2.16 crore, so "2,160,00,000" in the third line (and probably the screenshot) reads as 21.6 crore, a misplaced comma.
The "Estimated Time" figures also depend on a return assumption the post doesn't state. Working back, the three profiles (20L + 9L a year, 1 crore + 30L, 10L + 3.6L) land at 20, 15 and 30 years at roughly a 3.5% real return, which is lower than most FIRE calculators assume. At 7% real, the same inputs give about 16, 12 and 22 years. The freelancer's timeline is the most sensitive, because savings are small relative to the target and compounding does most of the work.
It would help readers to print the return and inflation assumption next to each result, and to show a second line with a withdrawal rate below 4% for the NRI case where the currency differs. Which return does the FinPlann calculator assume by default?
