Percentage Decrease Reference Chart

Ten base values from 10 to 10,000, against eighteen decrease rates from 2% to 90%, a wider lookup table than the homepage's compact chart, for anyone who needs more coverage at a glance.

How to Read This Chart

Every cell shows what remains of the row's base value after the column's decrease rate is applied, not the amount removed, the amount left over.

Step 1Base values run down the left edge, from 10 to 10,000.
Step 2Rates run across the header, from 2% to 90%.
Step 3That cell is the value remaining after your base has been reduced by that rate.

Reading the Chart, Two Examples

Example 1, Base 250, decrease rate 35%

162.50

Find the row Base = 250
Find the column Rate = 35%
Read the cell 250 × (1 − 0.35) = 162.50

A base of 250 reduced by 35% leaves 162.50, read directly off the chart's 250 row and 35% column.

Example 2, Base 2,500, decrease rate 60%

1,000.00

Find the row Base = 2,500
Find the column Rate = 60%
Read the cell 2,500 × (1 − 0.60) = 1,000.00

A base of 2,500 reduced by 60% leaves exactly 1,000.

Relationship to Percentage Decrease

Every cell in this chart is the direct output of the percentage decrease formula: Base × (1 − Rate ÷ 100). Nothing here is estimated or interpolated. It's a precomputed lookup table over the same calculation the homepage's calculator performs on demand for any two numbers you enter.

Frequently Asked Questions

How do I read a specific cell in this chart?

Find your base value in the left column, find your decrease rate in the top row, and the cell where they intersect is the resulting value after that decrease, not the amount removed.

Can I use this chart for a base value that isn't listed?

The chart covers common round bases; for anything else, use the percentage decrease calculator directly, which handles any value instantly rather than requiring a lookup.

Is this chart printable?

Yes, it uses plain HTML table markup with no interactive elements required to read it, so a browser's print function renders it cleanly without any calculator UI or navigation getting in the way.

Why does the chart round some values and not others?

Every cell is shown to at most two decimal places. Values that divide evenly display as whole numbers; values that don't (like 65% of 25) show their exact decimal remainder.

What's the difference between this chart and the one on the homepage?

This one is deliberately larger, 10 base values against 18 rates, versus 6 base values against 8 rates on the homepage, for readers who need a wider reference than the homepage's compact version provides.

Can I interpolate between two percentages not listed in the chart?

Not reliably by eye, since the relationship is linear in the rate but the chart's spacing between columns isn't uniform. For an exact value at a rate between two chart columns, use the calculator directly.

How precise are the chart values for large base numbers?

Exactly as precise as for small ones. Every cell is computed directly from the base and rate, not estimated or scaled from a smaller example, so precision doesn't degrade as the base value grows.

Can this chart be used for percentage increase instead of decrease?

Not directly, every cell here subtracts the rate from the base. For the equivalent increase table, see the percentage increase calculator, which computes growth on demand rather than through a fixed table.

Why does the chart include a 2% and 3% column when most examples use round numbers like 5% or 10%?

Smaller rates like 2% and 3% show up often in interest rates, inflation figures, and fine-grained business metrics, where the difference between 2% and 5% is meaningful and worth a dedicated column.

How do I extend this chart for my own custom base value?

Multiply your base by (1 − rate ÷ 100) for each rate you need, that's the exact formula every cell in this chart is built from, covered in full on the formula page.
