The software accounts for inflation by removing it from the cashflow modelling, except where the cost or values are projected to rise at a rate higher than inflation. These specific values can be tailored to suit your projections. We have included a base assumption as indicated by the Reserve Bank of New Zealand on their data from the last 30 years.
The software anchors all calculations around the age of ‘Person 1’, unless a field is specifically relevant to ‘Person 2’ e.g. Investments.
Surplus Funds & Personal Debt Assumptions
The default assumption is that 90% of surplus funds are first used for rapid mortgage repayment, and once all personal debt has been repaid, are then added to long-term savings. This is illustrated in the ‘Lifetime Cashflows’ graph.
When this occurs, then any ‘Project Funding’ will first be funded from savings (this is also true for first home purchases).
If there are specific investments that are separate to KiwiSaver, these can be added to long-term savings immediately in the ‘Lifetime Cashflows’ or withdrawn later and be brought back at a future age.
For ease of use, Planolitix has allowed for any effect of inflation so that all numbers can be entered in ‘today’s dollars’ e.g. A million dollars at a future retirement date has the same ‘value’ as a million dollars today. Any future income or expenses are treated the same way.
Anything that is expected to rise above inflation, such as housing values or investment returns, are pre-set at sensible levels based on RBNZ data and/or Govt guidelines.
Note: Due to the nature of cashflow modelling, gross or nominal figures have a significant impact when forecast over the very long-term, and can skew an illustration to where it is no longer relevant or useful. When entering an assumption for an investment return, it should be expressed as ‘after inflation’ e.g. Where inflation is 2% pa, a 5% after tax return should be entered as 3% pa.
