How Much Should You Invest in SIP Every Month?

Start from cash flow, not from social media targets

The right SIP amount is the one you can continue through ordinary life stress — rent, school fees, festivals, medical visits — without raiding the investment every few months. A smaller continuous SIP usually beats a large SIP that stops after three installments.

Minimums for many Nepali schemes often sit around Rs 500–1,000, depending on the product. That floor is about access, not about what you should invest. Your ceiling is set by surplus after essentials and emergency savings.

A practical budgeting sequence

List take-home income in NPR (salary, business drawings, remittance). Subtract non-negotiable living costs and debt EMIs. Set aside emergency cash (commonly discussed as several months of expenses — your number depends on job stability). Only then assign a SIP amount from remaining surplus.

Kathmandu living costs differ by neighborhood, family size, and lifestyle. Use your actual ledger as context, not a viral “average expense” post. Two households with the same salary can responsibly choose very different SIPs.

• Priority 1: essentials and high-interest debt.
• Priority 2: emergency buffer in liquid form.
• Priority 3: SIP aligned to multi-year goals.

NPR examples by surplus level (illustrative)

If your reliable monthly surplus is Rs 4,000, a SIP of Rs 1,500–2,500 may leave room for irregular costs. If surplus is Rs 20,000, a SIP of Rs 8,000–12,000 might be workable while keeping flexibility. These are teaching ranges, not recommendations for your household.

Remittance-heavy households sometimes receive larger amounts less smoothly. One approach is a conservative base SIP (for example Rs 5,000) plus discretionary top-ups when a larger remittance arrives — still without treating markets as a guaranteed store of value. Whatever amount you choose, channel it only through authorized SEBON-regulated mutual fund or capital-company pathways you have verified.

Any future-value illustration using 8–12% assumed annual returns is an estimate for planning math only. Returns are not guaranteed.

Goal-based sizing

Work backward from the goal. Suppose you want a rough educational corpus target of Rs 1,500,000 in 12 years. Different monthly SIPs under different assumed returns will map to different feasibility. If the required SIP exceeds your surplus, extend the timeline, lower the target, or increase income — do not stretch into unaffordable installments.

For retirement-style goals decades away, even Rs 3,000–7,000 monthly can matter if sustained, especially if you later step up the amount as income grows. Near-term goals (under 3 years) may need more cash-heavy savings and less market risk — SIP is not automatically ideal for every horizon.

Income growth and step-ups

When you receive a raise, festival bonus, or higher overtime abroad, consider increasing SIP by a fixed percentage of the raise rather than lifestyle inflation alone. A step-up of 5–10% annually on the SIP amount is a common planning idea; whether it fits you depends on expenses and job security.

Avoid sizing SIP to impress peers. Public comparison ignores debt, dependents, and risk capacity.

Stress-test the amount

Ask: if markets fall 20% and your job is uncertain for six months, can you keep the SIP without panic selling everything? If not, reduce the amount or strengthen cash reserves first.

Estimate monthly SIP scenarios under multiple assumed returns and durations. Pick an installment that still looks sensible when you assume lower growth and higher inflation — not only the optimistic case.
