ireland_overpay_mortgage_or_invest

Ireland: overpay the mortgage, invest, or top up a pension? Compares the same lump sum and/or extra monthly amount four ways at a horizon, after Irish tax: overpaying (keep the payment and shorten the term, or reduce the payment; interest saved, months cut, a tax-free return equal to the mortgage rate, freed payments saved after 33% DIRT), an Irish/EU ETF or fund (exit tax 38% in 2026, 35% from 2027, 8-year deemed disposal with credit), shares or an investment trust (CGT 31% above the €1,270 exemption) and a pension AVC/PRSA (relief at 20% or 40% within the age-related limit of 15%-40% of earnings up to €115,000; 25% lump sum tax-free up to €200,000, the rest taxed at the retirement rate; flags when it is still locked at the horizon). Returns the ranking, a plain verdict and the break-even growth rate at which each investment matches overpaying. Use this when someone in Ireland asks whether to overpay their mortgage or invest (ETFs, shares) or make pension AVCs, or whether to reduce the term or the payment; for a lump sum with no mortgage, use ireland_where_to_put_savings.

Discovered
ireland_pcp_vs_car_loan

Ireland: PCP vs car loan (credit union or bank) vs paying cash for a car. PCP: deposit or trade-in, level monthly payments that leave the GMFV (balloon) owed at the end, then pay the GMFV to own the car or hand it back (excess-km charge applied on hand back only); you do not own a PCP car until the final payment and cannot sell it without the lender’s permission, and the half rule (Consumer Credit Act 1995) lets you hand it back once half the total amount payable is paid. Loan: standard amortisation, you own the car from day one; a balance still owed at the end of the PCP term is counted as cleared then. Cash: the savings interest given up after 33% DIRT. APR is treated as an effective annual rate (EU Directive 2008/48/EC Annex I): monthly rate = (1 + APR)^(1/12) − 1; fees not modelled. Returns each route’s monthly payment, total paid, cost of credit, savings interest lost, car value kept and net cost over the PCP term (payments + lost interest − car value), the ranking, PCP total payable, the half-rule point, equity (end value − GMFV) and a plain verdict. All rates, the GMFV and the end value are the user’s figures or stated assumptions. Use this when someone in Ireland asks whether a PCP or a credit union/bank car loan is cheaper, whether to pay cash or finance a car, what the GMFV or balloon means for them, or when they can hand back a PCP car.

Discovered
ireland_pension_tax_relief

Ireland: income tax relief on personal pension contributions and AVCs (occupational scheme, PRSA, RAC, PEPP): the age-related limit (under 30 15%, 30-39 20%, 40-49 25%, 50-54 30%, 55-59 35%, 60+ 40% of earnings up to €115,000), relief at the marginal rate (2026 or Budget 2027 bands; no USC or PRSI relief), the net cost and the room left this year.

Discovered
ireland_sell_or_keep_rental

Ireland: should a landlord sell a rental property now or keep it?

Returns the difference, both paths by year, the break-even house-price growth and year-1 income.

Discovered
ireland_severance_tax

Ireland: how much of a redundancy or severance package is tax-free and the tax on the rest (Revenue Tax and Duty Manual Part 05-05-19, March 2026). Statutory redundancy is exempt; of the ex-gratia lump sum, the highest of the basic exemption (€10,160 + €765 per complete year), the increased exemption (+€10,000 less any tax-free pension lump sum, if not claimed in the last 10 years) and SCSB (average pay × years ÷ 15, less the pension lump sum) is tax-free, capped at €200,000 for life; the excess is taxed as pay (income tax and USC, not PRSI).

parental_leave_income_gap

Statutory parental leave pay for a birth parent and the income gap against normal pay (gross, before tax) in the UK (Statutory Maternity Pay), Ireland (Maternity Benefit), Canada (EI), Quebec (QPIP), Australia (Parental Leave Pay) or a US state’s paid family and medical leave (us-CA, us-NY, us-NJ, us-WA, us-MA and the rest; us-XX = no state program, FMLA unpaid), with an optional employer top-up. Use this for a quick cross-country comparison of one parent’s gross leave pay; for detailed national rules use the country tools (canada_ei_maternity_parental, quebec_qpip, ireland_maternity_leave_pay, uk_statutory_maternity_pay, australia_parental_leave_pay).

remote_work_savings

What working from home saves (or costs) in a year compared with commuting: car or transit commuting costs, lunches and work clothes saved, less extra home utilities, internet and equipment, and any pay cut.

UK: can I retire at 60 with £300k (or any age and pot)? Year by year to 95 for one person or a couple, on the 2027-28 rules after Budget 2026: pay and pension contributions until retirement, pots drawn from the normal minimum pension age (55, 57 from 6 April 2028) with 25% tax-free cash within the £268,275 Lump Sum Allowance and the rest drawn as taxable income, defined benefit pensions, the new State Pension from the State Pension age by date of birth (full £250.70 a week from April 2027), savings, a spending target in today’s money, and income tax (personal allowance tapered over £100,000; England/Wales/NI or Scottish bands, frozen to 2030-31) and National Insurance on pay.

uk_payments_on_account

UK Self Assessment: what is due on 31 January (balancing payment for the year just ended + first payment on account for the next) and 31 July (second payment on account). Each payment on account is half of the previous year's Self Assessment bill (income tax + Class 4 NI); none if that bill was under £1,000 or more than 80% of the tax was taken at source; capital gains tax and student loan go in the balancing payment only (gov.uk). Reproduces the gov.uk worked example. Use this when someone asks how much Self Assessment tax they pay in January or July.

Discovered
uk_pension_drawdown

UK: is my pension pot enough? One person living on a defined contribution pot in drawdown (plus ISAs, the new State Pension and any DB pension), year by year from tax year 2027-28 to an end age. Taxes every withdrawal with UK income tax (England, Wales and NI or Scotland; personal allowance £12,570 tapered above £100,000; thresholds frozen to 2030-31 by Finance Act 2026 s.10, then raised with inflation): 25% tax-free up to the £268,275 Lump Sum Allowance, either taken up front (optionally also drawing taxable income up to the personal allowance each year) or as 25% of each UFPLS (HMRC PTM063300). State Pension from the age set by date of birth (full rate £250.70 a week from April 2027), rising with inflation; minimum pension age 55, 57 from 6 April 2028. Returns the age the money runs out at a steady return (null = lasts), the highest spending that lasts to the end age, a seeded Monte Carlo (1,000 lognormal return paths centred on the return, with the volatility given): the chance the spending lasts, the run-out age in the worst 10% of paths and the spending that lasts in 90% of paths; the tax-free cash taken, first-year and lifetime income tax, and the three tax-free-cash methods compared. Return, inflation and volatility are the user’s assumptions. Use this when someone in the UK asks whether their pension pot is enough to retire, how long drawdown will last, how much they can safely withdraw, or whether to take the 25% tax-free cash up front or as UFPLS.

State figures are each state’s own (marked official or check); where a state figure was not found, the result says so and the caller can pass it.

Discovered
us_pension_lump_sum_vs_monthly

US: a defined benefit pension’s lump sum offer against its monthly payments. Returns the interest rate the pension is paying (the discount rate at which the monthly payments, each weighted by the chance of being alive from the SSA 2023 period life table used in the 2026 Trustees Report, equal the lump sum; also the rate if you live exactly to life expectancy), the pension’s value at the user’s expected return, the plain break-even age, the age the lump sum runs out paying the same monthly amount at that return (the break-even once growth counts), life expectancy, the chance of being alive at each age, the payment’s buying power at life expectancy after inflation, and the PBGC maximum monthly guarantee at the start age (2026 and 2027 tables). Supports single life or joint and survivor (spouse age, survivor %) and a yearly COLA; return and inflation are the user’s assumptions; before tax. Use this when someone asks whether to take a pension lump sum or the monthly pension, what interest rate their pension is paying, or the break-even age of a lump sum offer.
