It would be useful to have a feature that allows users to project and track their Retirement Annuity (RA) and Tax-Free Savings Account (TFSA) pots. The goal is to calculate how these investments could grow over time based on basic inputs.

Retirement Annuity (RA)

Required Inputs:

Current balance

Time frame (years)

Contribution amount

Contribution frequency (monthly, quarterly, yearly)

Annual contribution increase (%)

Expected annual growth rate (%)

Tax-Free Savings Account (TFSA)

Required Inputs:

Current balance

Contribution amount

Contribution frequency (monthly or yearly)

Expected annual growth rate (%)

Rules to apply:

Contributions capped at R500,000 lifetime limit

After reaching the cap, no further contributions are added — only growth is calculated

Graph Display

Each plan (RA, TFSA, and potentially others) should be displayed as separate lines on the projection graph

Each line should be toggleable (on/off) for comparison or isolation

A sum total line should be included to show the combined projected value of all active plans

The sum total line should also be filterable, updating dynamically based on which individual plans are toggled on
