How to use this calculator
Adjust the inputs to your own scenario, then review the result alongside the assumptions below. The $ symbol is a currency label; the tool does not convert exchange rates.
Worked example
At zero return, ending balance equals initial capital plus every scheduled contribution.
The formula
Monthly deposit in year y = initial monthly deposit × (1 + contribution increase)^(y − 1); compound the balance monthly.
What the result means
Compare the output with the stated assumptions. Changing an input changes the arithmetic; it does not establish how a real trade or investment will perform.
Assumptions and limitations
Increase applies at the start of each new year; end-of-month deposits; no income affordability checks, tax, fee, or inflation adjustment.
