Choose a monthly SIP amount from dependable surplus after essentials, debt payments, emergency savings and upcoming bills. No fixed percentage of salary suits every household in Nepal.
Someone earning Rs 40,000 with low housing costs may have more room to invest than someone earning Rs 70,000 while supporting dependants and repaying a loan. Start with your actual budget, then check whether a market-linked fund suits your goal.
Step 1: Calculate your dependable monthly surplus
Use take-home income after payroll deductions. Avoid counting an uncertain bonus, overtime payment or promised pay rise as regular salary.
Potential investing surplus = take-home income − essentials − debt payments − planned-expense reserves − emergency savings − a cash buffer.
This is a budgeting worksheet, not a rule to invest every remaining rupee. All figures below are hypothetical household choices.

If your result is zero or negative, a new SIP is not the immediate priority. Stabilising your budget is progress. With expensive debt, compare the interest saved by repayment against uncertain investment returns, allowing for prepayment charges and the need to retain emergency cash.
Step 2: Match the investment to the deadline
Do not put next term’s school fees or emergency money into an equity-oriented fund merely because it accepts monthly payments. The payment schedule does not change the underlying investment risk.
For a goal many years away, assess whether you can tolerate losses and whether the scheme’s portfolio fits the goal. A longer horizon gives more time but does not guarantee a profit. As a fixed deadline approaches, review how much risk you can still afford and allow time for redemption processing.
Step 3: Understand what Rs 3,000, Rs 5,000 or Rs 10,000 could become
The tables below are mathematical scenarios, not forecasts for any Nepal mutual fund. They assume a fixed payment at the beginning of each month, an annual nominal return divided by 12, and monthly compounding. There are no missed contributions or withdrawals. Charges, taxes and inflation are not deducted; any distributions are assumed to remain invested within the modelled total return.
The tables use beginning-of-month payments, so they may differ from a calculator that assumes payments at month end. Neither model reproduces an actual fund statement: real allotments use dated NAVs, and realised results depend on fees, distributions and the dates each payment clears.

The 0% column is not a worst-case outcome. Investments can finish below contributions. For example, a constant −5% nominal annual scenario would turn Rs 5,000 at the beginning of every month for 10 years into approximately Rs 470,953, compared with Rs 600,000 contributed, before charges and taxes. Actual market paths can produce different results even when headline averages look similar.
How the projections are calculated
For a non-zero monthly rate: FV = P × [((1 + i)n − 1) ÷ i] × (1 + i), where P is the monthly payment, i is the annual nominal rate divided by 12, and n is the number of months. At 0%, FV = P × n. Values are rounded to the nearest rupee.
The final multiplier reflects beginning-of-month payments. An end-of-month model omits it. This timing difference can explain why two calculators disagree. Under identical assumptions, Rs 7,500 produces exactly the midpoint of the Rs 5,000 and Rs 10,000 projections before rounding, because the formula scales directly with the contribution.
Use the SIP calculator to explore your amount, but check its payment-timing and return assumptions before comparing results.
Step 4: Build a salary-day routine
1. Reserve the money needed for essential bills and upcoming annual expenses.
2. Choose a contribution you can maintain during an ordinary difficult month.
3. Use an accepted payment method and, where supported, a standing instruction that leaves time after salary receipt.
4. Check the payment and allotment rather than assuming automation succeeded.
5. Review the budget after a salary change, new loan, rent increase or change in dependants.
If your salary arrives late, protect essential spending first. Ask the fund manager about amendment, missed-payment and cancellation rules. Pausing future purchases is different from selling units you already own.
Should you increase the SIP every year?
Only increase it when your finances support the change. A hypothetical 10% annual increase takes Rs 5,000 to Rs 5,500 in year two and Rs 6,050 in year three. Contributions across those three years would total Rs 198,600, compared with Rs 180,000 for a fixed Rs 5,000 monthly plan.
The higher future value of a step-up plan partly comes from investing more money. It is not evidence of a higher investment return. Confirm whether your fund supports automatic increases or requires a manual amendment.
Frequently asked questions
The example above leaves Rs 3,000, but your expenses may leave less, more or nothing. Use your own take-home income and obligations. Do not borrow to copy the example.
It can be a starting point for discussion, not a recommendation. Test whether it leaves adequate room for debt, emergency savings and predictable expenses.
No fixed contribution guarantees that result. The outcome depends on time, realised returns, costs and future increases. Also consider how inflation changes what Rs 1 crore could buy by the time you reach it.
First consider overdue obligations, emergency reserves and near-term goals. Invest only the portion that fits your overall plan; a bonus does not have to become either a full lump sum or a permanent higher SIP.
Before starting, review the account setup checklist and the common beginner mistakes.
