Disclaimers
- This is a model, not a prediction. Actual results may be higher or lower — we cannot predict changing interest rates or other factors that will affect your decision.
- The calculator is a guide only and is not intended to be your sole source of information when making a financial decision.
Assumptions
- The initial deposit is made today.
- Regular deposits are made at the end of each year, month, fortnight, week or day, based on the deposit frequency you set.
- Interest is credited either monthly or annually, in line with standard industry practice.
- Results are shown in future dollars — no adjustment has been made for inflation.
- Any delayed-start comparison uses the same regular deposit frequency as your main strategy.
