Explore how time and reinvested returns can change the future value of a lump sum. Enter a starting amount, an assumed annual return and the number of years to view growth under monthly compounding.
How to use it
- 1
Enter only the amount invested at the beginning of the period.
- 2
Choose a hypothetical annual return and the number of complete years.
- 3
Compare nominal growth with inflation, fees and tax before judging purchasing-power improvement.
Formula and methodology
Future value = principal × (1 + annual rate ÷ 12)^(12 × years). Growth equals future value minus the original principal.
Uses standard financial arithmetic with editable rates and terms. Tax, bank and product-specific rules require current official confirmation.
Worked calculation example
PKR 500,000 growing at an assumed 10% annual rate compounded monthly for five years reaches approximately PKR 823,500 before tax, fees and inflation.
How to interpret your result
Use the projection to compare saving discipline and time horizons; it is not a promised investment return.
Input guide
Use the investable starting principal.
Enter a conservative net annual return after fees.
Match the period to the actual goal date.
Scenario comparison
| Scenario | What it demonstrates |
|---|---|
| PKR 500,000 at 10% for 5 years | shows growth from time and compounding. |
| Same principal at 7% | tests a conservative-return scenario. |
| Same return for 10 years | demonstrates the effect of a longer horizon. |
Common mistakes to avoid
- Using an advertised best-year return as a permanent rate.
- Ignoring tax, fees and inflation.
- Comparing investments with different risk as if return were guaranteed.
Check the product's official fee schedule, risk disclosure and historical—not promised—returns.
What can affect the result?
Return variability
Real investments rarely deliver the same return every month or year.
Inflation
A larger future balance may buy less if prices rise over the same period.
Fees and tax
Management fees, taxes and transaction costs reduce net compound growth.
Limits of this estimate
The projection assumes a constant rate compounded monthly and excludes additional contributions, withdrawals, tax, fees, inflation and investment risk.
