Inflation is the rate at which the general price level of goods and services rises over time, reducing how much each rupee can buy. In Nepal, inflation is officially measured using the Consumer Price Index (CPI), published monthly by Nepal Rastra Bank based on a basket of goods and services weighted by household spending patterns.

The CPI is a weighted average of prices for a fixed basket of consumer goods and services such as food, housing, clothing, transport, education and health. Changes in the CPI over time show how the overall cost of living is changing.

Nepal Rastra Bank (the central bank) publishes monthly and annual consumer price inflation figures, while the National Statistics Office compiles the underlying price and expenditure survey data used to build the CPI basket.

Enter an amount, a base year and a target year. The calculator chains together the configured annual CPI inflation rates between those two years to compute the inflation-adjusted equivalent value, purchasing power change and related statistics.

Purchasing power is the quantity of goods or services that a unit of currency can buy. When inflation rises faster than income, purchasing power falls — the same rupee amount buys less than before.

Because prices of goods and services generally rise over time due to inflation, while the face value of the currency stays the same. A note that could buy a full basket of groceries a decade ago now buys only part of that basket.

Nominal value is the face amount of money without adjusting for inflation. Real value is that amount adjusted for inflation to reflect actual purchasing power in a given year's prices.

The inflation multiplier shows how many times prices have grown between two years. A multiplier of 2.0x means prices have doubled over that period.

Cumulative inflation is the total percentage increase in prices across the entire selected period, as opposed to the annualised (average yearly) inflation rate.

Annual inflation is the average yearly rate of price increase, while cumulative inflation is the compounded total increase over the whole period — cumulative inflation is always larger for periods longer than one year.

This calculator projects future prices by compounding a configurable assumed annual inflation rate (either a historical average or a custom rate you set) for years beyond the latest available CPI data.

No. Future projections are estimates based on assumptions and historical trends. Actual future inflation depends on unpredictable factors like monetary policy, global commodity prices, exchange rates and political events.

Nepal's inflation is influenced by monsoon-dependent agricultural output, its open border and trade dependence with India, global fuel and commodity prices, exchange rate movements and domestic supply constraints.

Because the Nepali Rupee is pegged to the Indian Rupee and Nepal imports a large share of goods from India, price changes in India tend to transmit strongly into Nepal's domestic inflation.

Food inflation measures price changes specifically for food and beverage items in the CPI basket. It tends to be more volatile than overall inflation because it is affected by harvests, weather and perishability.

Food makes up the largest weight in Nepal's CPI basket and is highly sensitive to monsoon patterns, transport bottlenecks in hilly terrain, and cross-border supply disruptions.

Core inflation excludes volatile items such as fresh food and fuel to show the more stable, underlying inflation trend driven by broader demand and monetary conditions.

Compare your salary growth rate to the annualised inflation rate for the same period using this calculator's "Custom Inflation Rate" or "Official CPI" method — if your salary grows slower than inflation, your real purchasing power is falling even if your nominal pay is rising.

It means your real (inflation-adjusted) income is shrinking even though your nominal salary number is higher — you can afford less than before despite earning more rupees.

Use the Historical Money Converter tool above: enter an amount, choose the "from" year and the "to" year, and the calculator will chain the configured annual CPI rates to show the equivalent value.

Nepal has experienced episodes of double-digit inflation historically, particularly during supply disruptions, fuel crises and periods following major earthquakes or trade blockades. Exact historical peaks should be verified against official Nepal Rastra Bank archives.

The calculator ships with a configurable dataset of approximate historical annual inflation rates intended for educational and estimation purposes. Site owners should update the centralised configuration object with verified figures from Nepal Rastra Bank or the National Statistics Office for production accuracy.

Yes. All CPI rates, category multipliers, and assumptions are stored in one centralised JavaScript configuration object near the top of the code, so updates require only editing configuration values, not the calculation logic.

The base year is the reference year your starting amount belongs to. All comparisons and adjustments are calculated relative to prices in that year.

Statistical agencies periodically rebase the CPI (updating the reference basket and base year) to reflect changing consumption patterns, ensuring the index stays representative of how people actually spend money.

Inflation refers to rising domestic prices measured in local currency, while currency depreciation refers to a currency losing value relative to other currencies. The two are related but distinct — depreciation can contribute to imported inflation.

No. This tool is exclusively an inflation and purchasing power calculator for Nepali Rupees (NPR) and does not perform currency conversion between countries.

Deflation is the opposite of inflation — a sustained decrease in the general price level, which increases the purchasing power of money over time. You can model deflationary scenarios here using a negative custom inflation rate.

Hyperinflation refers to extremely rapid and typically accelerating price increases, often exceeding 50% per month, usually caused by severe monetary or fiscal instability. Nepal has not historically experienced hyperinflation.

If the interest earned on savings is lower than the inflation rate, the real value of those savings declines over time even though the nominal balance grows.

Common general strategies discussed in personal finance education include seeking returns that outpace inflation, diversifying across asset types, and periodically reviewing whether income and savings growth are keeping pace with the cost of living. This calculator is educational and does not provide personalised investment advice.

The real interest rate is the nominal interest rate minus the inflation rate. It represents the true growth in purchasing power from an interest-bearing asset.

Regional inflation can vary due to transportation costs, local supply and demand conditions, and differences between urban and rural markets, which is why Nepal Rastra Bank also publishes regional inflation breakdowns.

It visualises how the real value of a fixed rupee amount has eroded (or grown, in deflationary periods) year by year across the entire configured historical CPI dataset.

A visual gauge summarising how severely your selected period's inflation has eroded purchasing power, from mild to severe impact.

It lets you compare multiple inflation-rate assumptions (for example, a low, moderate and high scenario) side by side to understand a plausible range of future outcomes.

Official Nepal CPI (year-by-year chained rates), Average Historical Rate over the selected range, a Custom Fixed Inflation Rate you specify, and Category-Adjusted CPI for specific expense types.

It applies an illustrative weighting to the general CPI rate to approximate how a specific expense category, such as education or housing, may have inflated differently from the overall basket.

Private education costs in Nepal have historically risen faster than general prices due to rising demand for private schooling, infrastructure investment and service-quality costs, though exact figures vary by institution and year.

Healthcare costs often rise due to technology, imported medicine and equipment costs, and specialised service pricing, which can outpace general CPI trends and materially affect household budgets.

The bundled dataset is an approximate, illustrative configuration intended to demonstrate the tool. For financial, academic or legal use, always cross-check figures against official Nepal Rastra Bank publications.

This tool is for general educational and estimation purposes only. For legal, contractual or official purposes, consult certified inflation adjustment figures from Nepal Rastra Bank or a qualified professional.

The Wholesale Price Index (WPI) tracks prices at the wholesale or producer level, while the Consumer Price Index (CPI) tracks prices actually paid by consumers at retail level — this calculator is based on consumer-level inflation.

Nepal Rastra Bank publishes consumer price inflation data monthly, alongside broader macroeconomic and financial situation reports.

Nepal has averaged mid-single-digit to high-single-digit annual inflation over the past few decades, though the precise long-run average depends on the exact period measured — check the configured dataset or official sources for specifics.

While this calculator does not compute loans directly, it helps you understand that a fixed nominal payment becomes "cheaper" in real terms over time under positive inflation, since the rupee amount buys progressively less for the lender in real terms.

It is the absolute rupee difference between your original amount and its inflation-adjusted equivalent in the target year.

It shows how much purchasing power, in percentage terms, your fixed nominal amount has lost if it was not adjusted upward to keep pace with inflation.

This calculator works on an annual basis using yearly CPI rates. For sub-annual analysis, monthly CPI series from Nepal Rastra Bank would be required.

The calculator uses your selected calculation method (official average, custom rate, or category rate) as an assumption to project prices forward, since actual future CPI data does not yet exist.

Because inflation compounds year over year like interest, chaining each year's rate captures the true cumulative effect far more accurately than simply multiplying a single rate by the number of years.

It expresses your amount's buying capacity in terms of a reference year's prices, stripping out the effect of nominal price increases so you can compare "apples to apples" across time.

Yes, the Nepal Inflation Calculator is completely free, requires no signup, and runs directly in your browser.

Yes, the interface is fully responsive and optimised for mobile, tablet and desktop screens.

It can support educational exploration and illustration of inflation concepts, but for formal research always cite verified primary data from Nepal Rastra Bank, the National Statistics Office, or the World Bank.

Adjusted Value = Amount × Product of (1 + annual rate) for every year between the base year and target year, compounding each year's rate sequentially.

It is derived using the compound annual growth rate formula: (Ending Price Level ÷ Starting Price Level)^(1 ÷ number of years) − 1, expressed as a percentage.

Differences can arise from using different base years, different CPI basket compositions, rounding methods, or whether food and non-food components are separated — always compare like-for-like methodology.

It can provide a general estimate for internal planning, but formal price escalation clauses in contracts should reference an agreed, verifiable official index rather than an illustrative educational tool.

Site owners can update the centralised JavaScript configuration object with the latest verified annual rates from Nepal Rastra Bank at any time without touching the calculation logic.

Not necessarily — moderate, stable inflation is normal and even considered healthy by most central banks, while very high or very low/negative inflation (deflation) can each create economic challenges in different ways.

Income is the amount of money you receive, while purchasing power is what that income can actually buy after accounting for prevailing prices — rising income with even faster-rising prices still means falling purchasing power.
