Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Step-by-step calculation

Inputs are substituted below. Each line evaluates the next operation; intermediate values are displayed to 12 significant digits while the calculation uses full precision.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

The rate is your constant annual assumption, not a forecast. Negative rates represent depreciation; fractional years use exponential interpolation.

Automatic precision shows money to two decimal places and other numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.

Use +, −, ×, ÷, parentheses and %. A percentage is divided by 100. This does not change the main tool.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using Appreciation calculator

Projected value = starting value × (1 + annual change rate) raised to the number of years.

The rate is your constant annual assumption, not a forecast. Negative rates represent depreciation; fractional years use exponential interpolation.

A worked example

With starting value = 1000, annual change percent = 5, years = 2, the projected value is 1,102.50 (rounded to two decimal places).

Before you use the result

The rate is your constant annual assumption, not a forecast. Negative rates represent depreciation; fractional years use exponential interpolation. Calculations keep full browser-number precision. Money amounts are displayed to two decimal places; other results use up to 12 significant digits. Very large values may lose precision.

Example results for starting value

These examples use Annual change percent: 5; Years: 2. They are reference calculations, not recommended settings.

Starting value	Projected value
500	551.25
1000	1,102.50
2000	2,205.00
