Estimate your retirement savings from contributions and returns.

How do you estimate retirement savings?
Corpus = current savings × (1 + i)ⁿ + monthly × [((1 + i)ⁿ − 1) ÷ i], where i is the monthly return and n the months until retirement. This combines your current balance, ongoing contributions and an expected return into a single projection. It ignores inflation and taxes, so treat it as a planning estimate, not advice.
Understanding your result
This ignores inflation and taxes; treat it as a planning estimate, not advice.
Formula and method
Corpus = current savings × (1 + i)ⁿ + monthly × [((1 + i)ⁿ − 1) ÷ i], where i is the monthly return and n the months until retirement.
Assumptions and limitations
This ignores inflation, taxes and variable market returns. To estimate future purchasing power, use a lower “real” return rate. It is a planning aid, not financial advice.
Worked example
From age 30 to 65 at 7%, 20,000 plus 500/month could grow to several hundred thousand.

Frequently asked questions
Does it account for inflation?
No. To see today’s purchasing power, use a lower “real” return rate.
Why should I try more than one return rate?
Because actual returns are unknown and vary over decades, a single figure gives a false sense of precision. Running a cautious rate alongside an optimistic one produces a range, helping you see how sensitive the projected corpus is to assumptions you cannot control.
Does the result show today's money or future money?
The projected corpus is a future nominal figure and is not adjusted for inflation, so its real spending power will be lower than it appears. To gauge what it might buy, consider it alongside how prices could rise over the same period.
