Over the whole record
Across the 19 years from 2006 to 2025, prices in Sierra Leone rose +974.1% in total.
SLE 100 at the start of that period would need to be SLE 1,074 in 2025 to buy the same goods — leaving the original amount with 9.3% of its buying power.
Inflation in Sierra Leone, explained
The Sierra Leone’s national statistics agency publishes a Consumer Price Index that tracks the cost of a representative basket of goods and services in Sierra Leone. This CPI inflation calculator holds that index from 2006 to 2025 and compares any two of those years directly, rather than applying one assumed rate across the gap.
Over the full record, inflation in Sierra Leone has averaged 13.31% a year. The steepest single year was 2023 at +47.6%; the mildest was 2014 at +4.6%. Amounts are shown in SLE.
Worked example
SLE 100 in 2006 is worth SLE 1,074 in 2025. That is +974.1% cumulative inflation over 19 years, or +13.31% a year compounded. Put the other way round, the original SLE 100 now buys what SLE 9.31 bought back then.
Inflation calculator: SLE amounts
Every figure on this page is calculated and formatted in SLE, using Sierra Leone’s own grouping conventions. Enter any amount — a price, a salary, a savings balance — and the result stays in SLE throughout, including the year-by-year table and the chart.
Checking a salary or a return
The most common use is as a wage inflation calculator. Enter an old salary with the year it was earned and set the end year to 2025: the adjusted figure is what that salary would need to be today simply to keep pace. Anything above it is a real increase; anything below it is a pay cut in disguise. The same test applies to an investment return, a rent, or a contract rate — if growth did not clear the cumulative figure, it lost real value.
A note on accuracy
Figures come from the Consumer price index (2010 = 100) series, which compiles the CPI published by the Sierra Leone’s national statistics agency. They are annual averages, so a result may differ by a fraction of a percent from a calculator that compares two specific months. See the methodology for detail.

FAQ
Questions about Sierra Leone inflation
What is the inflation calculator?
The Yearly Inflation Calculator is a free online tool that shows how inflation changed the value of money between any two years. You choose a country, enter an amount, pick a start year and an end year, and it returns the inflation-adjusted value along with cumulative inflation, the average annual rate and the change in purchasing power. It uses official Consumer Price Index data rather than a guessed rate, and covers 192 countries.
How do you calculate the inflation rate?
Inflation is calculated from a price index, usually the Consumer Price Index. Take the index value at the end of the period, subtract the index value at the start, divide by the index value at the start, and multiply by 100. If the index moved from 120 to 126, inflation was (126 − 120) ÷ 120 × 100 = 5%. The index itself comes from pricing a fixed basket of goods and services repeatedly over time.
How is annual inflation rate calculated?
For a single year, the annual inflation rate compares that year’s index with the previous year’s: rate % = (CPI_this_year ÷ CPI_last_year − 1) × 100. Across a longer period, the average annual rate is the geometric mean — the constant rate that compounds to the same total: annual % = ((CPI_end ÷ CPI_start) ^ (1 ÷ number of years) − 1) × 100. It is deliberately not the simple average of the yearly rates, which would overstate the result because inflation compounds.
Where does the inflation data come from?
All figures come from the World Bank’s Consumer Price Index series (indicator FP.CPI.TOTL), which compiles the official CPI published by each country’s national statistics agency — the Bureau of Labor Statistics in the United States, the Office for National Statistics in the United Kingdom, MoSPI in India, and so on. The data is annual. It is built into the site rather than fetched live, so results are fast and stable.
Why does my country start at a later year?
Countries began publishing a consistent Consumer Price Index at different times, and some series have gaps where no figure was published. The year menus only ever offer years that have a published figure for the country you have selected, so you cannot pick a year the data does not support.
Why do results differ slightly from my government inflation calculator?
National calculators often compare specific months, or use a variant index, while this tool compares annual averages. Statistics agencies also revise and re-base their series periodically. Differences of a fraction of a percent are normal and expected; the magnitude and direction of the result will always agree.
