Work out a mortgage from the price, deposit, rate, and fees you type. Loan amount is purchase price minus deposit. This is formula-first math — not a country mortgage or stamp-duty law engine, and not tax, legal, or lender advice.
Monthly payments · 12 per year
Models a fixed period, then the rate you type for the rest of the term. Starting 2 years / 7% is illustrative — edit it.
Stamp duty: amount wins if you fill both amount and %. Agent = percent of price plus any flat fee. Link the Stamp Duty calculator if you want banded duty, then paste the amount.

P = max(0, price − deposit). Monthly rate r = annual/100/12, n = years×12. Repayment PMT = P×r×(1+r)^n / ((1+r)^n − 1) (or P/n if r is 0). Interest-only PMT = P×r. Step-up: amortise k = fixedYears×12 months at r1 to get remaining principal P2, then a new PMT on P2 over n−k at r2. Extra = new − old. Cash to complete = deposit + stamp duty + agent + legal + other — not the loan.
Purchase price and deposit are the first inputs. The loan is always max(0, price − deposit). Deposit % of price and LTV (loan ÷ price) update live so you can sanity-check the split.
Payments are monthly (12 per year). For a single rate, repayment uses the standard annuity formula with r = annual ÷ 100 ÷ 12 and n = term × 12. Interest-only charges P × r each month and leaves principal unchanged.
A rate step-up models a fixed period then a later rate: pay as if the initial rate lasts the full term for k months, read remaining principal, then re-amortise the leftover term at the later rate. Total interest uses r1 for the first k months and r2 after. The yearly table rolls those months up — not a 360-row dump.
Purchase costs are yours to type. Stamp duty is an amount or a percent of price (amount wins if both). Estate agent is percent of price plus any flat fee. Legal/conveyancing and other/survey are flats. For banded stamp duty, use the Stamp Duty calculator and paste the amount.
Monthly rate r = annual ÷ 100 ÷ 12, and n = term years × 12. Repayment payment is P × r × (1+r)n / ((1+r)n − 1), or P ÷ n if r is 0. Illustrative example: purchase 300,000, deposit 60,000, loan 240,000 at 5% for 25 years is about 1,403.02 per month.
Interest-only monthly payment is loan × r. The principal stays put until you repay it separately. On the same 240,000 at 5%, interest-only is 1,000 per month. Repayment includes principal each month so the balance reaches zero at term.
The first payment uses the initial rate over the full original term. After k months (fixed years × 12), remaining principal is recalculated, then a new payment is set on that balance over the leftover months at the later rate. Extra per month is new minus old. Illustrative: 240,000, 25 years, 5% for 2 years then 7% — repayment extra is about 274.70 per month.
No. This is not a country mortgage or stamp-duty law engine. Enter stamp duty as an amount or as a percent of price (amount wins if both are filled). For banded duty, use the Stamp Duty calculator, then paste the amount here.
Cash to complete is deposit + stamp duty + estate agent + legal/conveyancing + other/survey. It does not include the loan. Agent fees are percent of price plus any flat fee you type.
No. You enter the rates and fees. Starting numbers are illustrative only. MultiSwitch does not apply lender rules, tax law, or reliefs — see Terms.
