How this savings goal calculator works
The calculator uses the future value of an annuity formula: FV = M × ((1+i)ⁿ − 1) / i, where M is your monthly saving, i the monthly return and n the number of months. It first grows your starting amount, then solves for the monthly contribution needed to close the gap to your goal.
Where Sri Lankan savers put the money
For short goals (under 12 months) a high-interest savings account or short FD is safest. For 1–3 years, monthly-savings FDs or T-bill reinvestments at 9–11% work well. For 5+ year goals, consider unit trusts and a mix of assets to beat inflation.
Pro tip
Automate a standing order on your salary day so the saving goes out before you can spend it. Even Rs. 15,000 a month for 5 years at 10% grows to over Rs. 1.16M.
Frequently Asked Questions
How much should I save each month in Sri Lanka?
A common guideline is 20% of take-home pay, split between an emergency fund (3–6 months of expenses) and long-term goals. Use this calculator to work backwards from your actual target — the monthly amount needed depends on your goal, timeline and where you save it.
Where should I save the money?
For goals under 1 year, use a savings account or 3-month FD for liquidity. For 1–3 year goals, a laddered FD or T-bill portfolio at 9–11% is usually best. For longer goals, consider unit trusts or a mix of FDs and equity — but stick to instruments you understand.
Does this account for inflation in Sri Lanka?
The calculator uses nominal LKR figures — your target and monthly savings are in today's rupees. If your goal is 5+ years away, add a buffer of 5–8% per year to your target for Sri Lankan inflation.
What return should I assume?
For LKR savings in 2026, a realistic conservative assumption is 9–11% p.a. (bank FD or T-bill after 5% WHT is around 8.5–10.5%). Use 0% if you plan to keep the money in a current account — the calculator will show how much longer the goal will take.
