How to Use These Government Scheme Calculators

Follow this 5-step process to maximize government support for your property purchase and understand all available schemes.

1

Check First-Time Buyer Eligibility

Start with the First-Time Buyer Calculator to assess all available benefits. First-time buyer definition: never owned property anywhere in the world (UK or abroad). Key benefits: (1) Stamp Duty Relief - pay 0% on first £425,000 (vs £300,000 for existing owners), save up to £11,250 on £625,000 property, (2) Lifetime ISA - 25% government bonus on savings up to £4,000/year (max £1,000 bonus), total £32,000 saved + £8,000 bonus = £40,000 deposit, (3) Shared Ownership - buy 25-75% share, pay rent on remainder, lower deposit (5-10% of share = £6,250-12,500 on £250k property), (4) First Homes Scheme - 30-50% discount on new builds (£300k property for £210k with 30% discount), (5) Help to Buy Equity Loan - government lends 20% (40% London), interest-free for 5 years. Calculator shows: total savings from all schemes, deposit required, monthly costs, eligibility for each scheme.

💡 First-Time Buyer Tip: Combine multiple schemes for maximum benefit. Example: £250,000 new build property. (1) Use Lifetime ISA: £32,000 saved + £8,000 bonus = £40,000 deposit (16%), (2) Apply for Help to Buy: government lends 20% (£50,000), you need 5% deposit (£12,500), use £12,500 from LISA, keep £27,500 for costs/emergency, (3) Stamp duty: £0 (under £425,000 FTB threshold, save £2,500), (4) Total: buy £250k property with £12,500 deposit (5%), £187,500 mortgage (75%), £50,000 equity loan (20%), £0 stamp duty. Monthly: £187,500 mortgage at 5% = £1,095, equity loan £0 for 5 years, total £1,095/month. After 5 years: equity loan interest starts at 1.75%, rising with RPI+1%. Plan to remortgage or staircase (buy more shares) before interest starts.

Calculate Stamp Duty Savings

Use the Stamp Duty Calculator to determine tax liability and first-time buyer relief. UK Stamp Duty Land Tax (SDLT) rates (October 2025): First-Time Buyers - 0% up to £425,000, 5% on £425,001-£625,000 (max property £625,000 for relief), Standard Buyers - 0% up to £250,000, 5% on £250,001-£925,000, 10% on £925,001-£1.5m, 12% above £1.5m, Additional Properties - add 3% surcharge to all bands. Examples: (1) £300,000 FTB = £0 (save £2,500 vs standard), (2) £500,000 FTB = £3,750 (save £10,000 vs standard), (3) £625,000 FTB = £10,000 (save £11,250 vs standard), (4) £650,000 FTB = no relief (over £625k limit), pay £15,000 standard rate. Calculator shows: SDLT breakdown by band, first-time buyer savings, comparison with standard rates, additional property surcharge.

⚠️ Stamp Duty Planning: First-time buyer relief only applies if: (1) Never owned property anywhere in world, (2) Property price ≤£625,000, (3) Intend to live in property as main residence. If buying with partner: both must be first-time buyers for relief. If one owned before: pay standard rates. Couples strategy: if one owned before, consider buying in FTB partner's sole name (if affordable on their income alone) to claim relief, then add other partner to title later (no SDLT on gift between spouses). Property over £625k: no FTB relief, pay standard rates. Consider: (1) Negotiate price to £625k or below to qualify, (2) Buy £625k property, negotiate fixtures/fittings separately (not subject to SDLT), (3) Wait and save larger deposit for property under £625k. Additional property surcharge: +3% on all bands if you own any other property (even abroad, even if mortgaged). Exceptions: replacing main residence (sold within 3 years), inherited property (not lived in).

Maximize Lifetime ISA Benefits

The Lifetime ISA Calculator shows government bonus and growth potential. Lifetime ISA (LISA) rules: (1) Age 18-39 to open, (2) Save up to £4,000/year, (3) Government adds 25% bonus (max £1,000/year), (4) Use for first home (£450,000 max price) or retirement (age 60+), (5) Penalty: 25% charge on withdrawal for other purposes (lose bonus + some capital). Example savings journey: Age 25-32 (7 years): save £4,000/year × 7 = £28,000, government bonus £1,000/year × 7 = £7,000, investment growth 4%/year = £5,000, total = £40,000 for deposit. Monthly saving: £333/month = £4,000/year. Calculator shows: total savings, government bonus, projected growth, deposit available, comparison with regular savings. Combine with Help to Buy: LISA provides deposit, Help to Buy reduces deposit needed (5% vs 10-15%), use LISA funds for 5% deposit + costs.

✅ LISA Maximization Strategy: Start early to maximize bonus. Age 18: can save for 22 years (until 40), max £88,000 saved + £22,000 bonus = £110,000 (before growth). Age 35: only 5 years left, max £20,000 + £5,000 bonus = £25,000. Open LISA immediately if planning to buy in next 2+ years (must be open 12 months before first home purchase). Contribution strategy: (1) Max LISA first (£4,000/year for 25% bonus), (2) Then max regular ISA (£20,000/year total ISA allowance, LISA counts towards this), (3) LISA + regular ISA = £4,000 LISA + £16,000 regular ISA = £20,000 total. Investment vs cash LISA: Cash LISA (0.5-2% interest) = safe but low growth, Stocks & Shares LISA (4-7% average) = higher growth but volatile. For 5+ year timeline: consider stocks & shares LISA for growth potential. For 2-4 years: cash LISA for safety. Withdrawal: no penalty for first home under £450,000, 25% penalty for other withdrawals (lose bonus + 6.25% of capital). Example: save £4,000, get £1,000 bonus = £5,000, withdraw early: 25% penalty = £1,250 charge, receive £3,750 (lose £250 of your own money).

Evaluate Shared Ownership

The Shared Ownership Calculator shows costs of buying a share and renting the rest. Shared Ownership: buy 25-75% share of property, pay rent on remaining share, staircase (buy more shares) over time. Eligibility: household income under £80,000 (£90,000 London), first-time buyer or previous homeowner who can't afford market property. Example: £300,000 property, buy 50% share (£150,000). Costs: (1) Deposit: 5-10% of share = £7,500-15,000 (vs £30,000 for full property), (2) Mortgage: £135,000-142,500 at 5% = £790-835/month, (3) Rent: 2.75% of remaining share = 2.75% × £150,000 = £4,125/year = £344/month, (4) Service charge: £100-200/month, (5) Total: £1,234-1,379/month. Compare to full ownership: £300k property, 10% deposit (£30k), £270k mortgage = £1,580/month. Shared ownership saves £200-350/month + lower deposit (£7,500 vs £30,000). Staircasing: buy more shares over time (10% minimum increments), reduce rent, eventually own 100%. Resale: sell share or full property, housing association has first refusal.

💡 Shared Ownership Strategy: Start with minimum share (25-40%) to minimize deposit and monthly costs, then staircase as income grows. Example: £300k property. Year 1: buy 25% (£75k), deposit £7,500 (10%), mortgage £67,500 = £395/month, rent on 75% (£225k) at 2.75% = £516/month, total £911/month. Year 5: income increased, staircase to 50% (+£75k), new mortgage £142,500 = £835/month, rent on 50% = £344/month, total £1,179/month (still less than full ownership £1,580). Year 10: staircase to 100% (+£150k), own outright, no rent, mortgage £292,500 = £1,710/month (but property now worth £350k+). Pros: lower deposit, lower monthly costs, get on property ladder, benefit from appreciation on full value. Cons: pay rent + mortgage, service charges, restrictions on alterations, staircasing costs (valuation £500-1,000, legal £500-1,000), rent increases annually (RPI+0.5%). Best for: first-time buyers with limited deposit, those who can't afford full ownership, areas with high property prices (London, South East).

Calculate Help to Buy Equity Loan

The Help to Buy Calculator shows equity loan amounts and repayment costs. Help to Buy Equity Loan (England only, scheme closed to new applications December 2022, existing loans continue): Government lends 20% (40% London) of property value, interest-free for 5 years, then 1.75% year 6, rising with RPI+1% annually. Example: £300,000 new build. Equity loan: 20% = £60,000 (40% London = £120,000). Your costs: 5% deposit (£15,000), 75% mortgage (£225,000), 20% equity loan (£60,000). Monthly: mortgage £225k at 5% = £1,315, equity loan £0 for 5 years. Year 6: equity loan interest 1.75% × £60k = £1,050/year = £87.50/month, total £1,402.50/month. Year 7: interest rises to RPI+1% (assume 3% RPI = 4% rate), £60k × 4% = £2,400/year = £200/month, total £1,515/month. Repayment: pay back 20% of current property value (not original £60k). If property worth £350k: repay 20% = £70k. If worth £250k: repay 20% = £50k. Options: (1) Repay in full (remortgage or savings), (2) Partial repayment (min 10% of current value), (3) Sell property and repay from proceeds.

⚠️ Help to Buy Exit Strategy: Plan to repay or remortgage before year 6 when interest starts. Strategy: (1) Remortgage Year 5 - property appreciated £300k to £330k, remortgage at 80% LTV = £264k (was £225k), use extra £39k to partially repay equity loan (10% of £330k = £33k), reduce equity loan from £60k to £27k, lower future interest charges. (2) Overpay Mortgage - overpay £200-300/month years 1-5, reduce mortgage from £225k to £200k, remortgage at 75% LTV = £247.50k, use £47.50k to repay equity loan in full. (3) Staircase - buy out equity loan in stages (min 10% of property value), reduce interest charges. (4) Sell and Move - sell property, repay equity loan (20% of sale price), use remaining equity for next property. Risks: if property falls in value, still owe 20% of current value (could be less than original loan). If property rises significantly, owe more (20% of £400k = £80k vs original £60k). Interest rises with RPI: if RPI 5%, year 7 rate = 6%, £60k × 6% = £3,600/year = £300/month. Budget for interest from year 6 or plan exit strategy.
