How to Use This Comparison Tool
Start with Option A: purchase price, deposit, interest rate and term for the first loan structure. Click "+ Compare Against Another Option" to add a second, and again for a third. The most useful pattern is keeping purchase price and deposit identical across options and changing only the rate, so you can see exactly what a bank's offer is worth in rand terms.
Click Compare Bond Repayment to see monthly repayment, total interest and payoff date for every option you filled in, side by side. A small rate difference compounds into a large total-interest gap over a 20-year term, this comparison makes that gap visible before you commit to a bank.
Why Compare Bond Offers Side by Side?
A 0.25% rate difference on a R1.5 million bond sounds small, but over a 20-year term it typically works out to tens of thousands of rand in total interest, and a real difference in your monthly repayment. Banks and bond originators rarely present competing offers in a way that makes the total cost easy to compare at a glance, they show you a monthly figure, not the compounding effect over the full term.
This tool puts your loan offers side by side in one view instead of checking each one separately on the single-loan Bond Repayment Calculator. It's also useful beyond bank shopping, comparing a 20-year term against a 25-year term on the same rate shows exactly what the shorter term saves in total interest against what it costs in higher monthly repayment.
