Irish tax/investment calculator I built - feedback welcome

Added BP65 as its own income field — appears once you enter age 65, taxed like the State Pension (no USC/PRSI).

This is a very useful update. There's one bug (or it could be user error). If I input an amount for BP65 it will persist in the calculation even if it is removed due to the age field being changed to a value other than 65. For example if modelling when someone is 65 and then remodelling when they're 66 (adding state pension).

Confirmed, real bug — not user error. The BP65 amount wasn't clearing when age moved away from 65. Fixed: the field's value is reset the moment it no longer applies, and the calculation itself won't accept it unless age is exactly 65. Thanks for catching it.
 
@PaddyW, Fixed. the main Income Tax Calculator now has a "Rent paid this year" field that applies the Rent Tax Credit directly to your take-home. Thanks for flagging it.
 
Hi @Brendan Burgess @ClubMan,
Also, if anyone here invoices clients directly (contractors, freelancers), I put together a free invoice generator: irajeshsood.com/invoice-generator Edit the invoice directly, live VAT/totals, PDF export, recurring billing for regular clients. No signup, nothing leaves your browser. Might be useful alongside the tax figures above.
 
A calculator for how much CGT is due when you sell a property that has been both your PPR and then a rental property.

Another common request was how much the break fee on a fixed term mortgage might be using the interbank rate and whether it was worth it versus the interest savings.
 
Thanks @Zenith63, the mortgage break fee one's live now: "Mortgage Break Fee Calculator".
Enter your locked-in rate, what's on offer today, and how long's left on the fixed term, and it works out the Early Repayment Charge plus whether switching actually saves more than the fee.
Formula's straight from a regulated lender's own published policy, and I checked it against several worked examples before posting this.

One thing that surprised me building it: a bigger rate drop tends to make breaking look worse, not better, the fee scales with the rate gap faster than the interest saved does. Wrote that up in the calculator's FAQ since it's counter-intuitive.

The PPR-then-rental CGT one is still on my list, haven't got to it yet.
