Guide to the use of mortgage calculators: monthly provision, interest and early repayment judgement
The first payment, loan, interest rate, duration, repayment and early payment judgement of the mortgage calculator is to be explained in the context of the purchase of the house, avoiding errors in the monthly contribution only.
The budget for buying a house can't be a one-month job.
The value of the mortgage calculator is to place the price, down payment, interest rate and duration of the loan in the same cash flow map. The buyer can estimate the monthly repayments before comparing the different down payment rates, repayment modalities and early repayment schemes to determine whether there is room for family income. The result of the calculation is not equal to the final approval of the bank, nor does it automatically include tax charges, maintenance funds, brokerage fees, renovation fees, property charges and interest rate adjustments.
Before starting the input, answer “what is the total house price” “what is the available down payment” “for how long is the income ready to be held” “is it likely to change”. If only a set of optimistic figures were entered, the tool would give an answer that seemed precise but inappropriate for decision-making. It would be more prudent to establish three sets of conservative, baseline and stress programmes.
From house price to loan principal.
The principal amount of the mortgage is usually equal to:
Principal loan = Total housing price - 首付款
However, the actual amount available is also subject to limitations in terms of loan size, value assessment, income certification, credit records and local policies. If we're done, 2,000,000 Dollar, down payment 600,000 Theoretically, the amount of the loan 1,400,000 (a) Dollars; If the bank assesses the price below the price at which it is delivered, the actual loan may be valued at the value at which the difference will need to be replenished by an increase in cash.
Enter the following text to suggest:
- Total house price: The contract is negotiated and the unit is kept in dollar terms, and the renovation budget is not mixed.
- Lump-sum or proportional: Only one type of input can be selected, and the confirmation tool does not repeat deductions.
- The amount of the loan: is based on a pre-trial approval or formal contract by the bank, the theoretical value being used only for the budget.
- Interest rate: The base rate, plus or discounts are recorded, and the pricing cycle is re-pricing.
- Duration: Common
10、20、30The longer the period, the lower the usual rate of interest, the greater the total. - Repayment mode: Equivalent principal monthly, flat, and pre-capital level.
The mortgage calculator's operating process
- OpenMortgage Calculators, enter the total house price and the planned down payment, first receiving the principal of the theoretical loan.
- Enter the annual interest rate and the duration of the loan, and record the date of the interest rate assumption. If the floating interest rate is applied, the current value is used before the upward scenario is created.
- The first month of supply, the month of stabilization, total interest and the remaining principal are compared.
- Monthly contributions will be made to the family budget table, with an indication of property, transport, education, insurance and emergency savings. The monthly mortgage should not swallow all disposable income.
- Change in the down payment ratio, for example, by increasing
100,000The Head of State pays to observe monthly supplies and interest reductions, which are compared with the earnings and security of cash retained. - If early repayment is planned, the expected time and amount are entered, the “cut-off period” and “lower monthly provision” are simulated, respectively, and the default amount is checked with the lending institution.
Difference between principal and principal of equivalent amount on mortgage
The equivalent interest rate allows for a relatively stable monthly repayment, suitable for income patterns and for home buyers who need to arrange for accurate family cash flows. It had a higher rate of interest in its prior repayments and might have saved more significantly in the future, but needed to confirm whether the contract was permissible and what the costs were.
The equivalent principal is divided equally between principals, which are provided for a higher amount in the first month and then decreases as the balance decreases. Its total interest is usually lower and suitable for those with higher or defined bonus income in previous years. If the family has just bought a house to renovate and raise children, the initial pressure may render the equivalent principal inappropriate.
The term “total interest is less” should not be interpreted directly as “economically better”. If the overpayment of the down payment results in no contingency, future unemployment can be met only by borrowing high-interest consumer loans, and the savings on housing loans may soon be offset.
Errors and counter-examples: Why is the advertising month not credible?
| Mistakes | Problems caused by the | Correct check |
|---|---|---|
| I'll use the sale to get the loan. | Ignore down payment and assess price differences | Confirm the actual loan principal |
| It's just the preferential rate. | Months after repricing for possible rise | Calculate base, float and preferential end of the three tranches |
| Total repayments as total cost | Missing taxes, insurance and renovations | Single purchase of house, one-time and ongoing expenditure |
| Put the down payment in the house. | There's no liquidity after the house is delivered. | Pre-positioning contingency and renovation buffers |
| You can extend the term when you see the month is low. | Long-term interest has increased significantly | Compare total interest and retention periods |
Example: An ad written "Leave down" 300,000 Yuen, the moon 5,000 (c) The amount of the loan is not specified. - Put it on. 5,000 Dollar times 360 The period is only a nominal sum, which is not yet certified as the principal, interest rate, first-time days and costs and is not a basis for determining whether or not it is cost-effective.
Real scene: down payment versus liquidity trade-offs
Chen looks at the total price 1,800,000 I'm in a house with a family of... 750,000 Cash in dollars. Option A Payments 600,000 The Führer pays, reserves. 150,000 (a) Dollars; Option B Payments 750,000 The Führer pays, the loan is even less. She entered two sets of loans using a mortgage calculator, and placed the monthly cash supply, the remaining cash and the renovation budget in the family cash flow statement.
Option A may be more secure if option B allows only a small reduction in monthly funding, leaving the account balance below six months ' subsistence. Conversely, if revenues are stable, no renovations and no education expenditures are incurred, an increase in down payment may significantly reduce interest rates. Decisions would also be preceded by consideration of alternative uses of cash, such as early repayment of other high-interest debt, payment of taxes and charges or the establishment of contingency funds, rather than a comparison of a monthly schedule.
Advance repayment: first ask the rule and then save
At least four data are required for the calculation of early repayments: date of application, current remaining principal, amounts settled at bank, default or fees. The tool can estimate the reduced future interest, but it is not known whether the bank is treated as “reduced duration” or “reduced month” or as a substitute for a written offer.
If early repayment occurs in the early years of the loan, the remaining principal is large and the theoretically avoidable interest is greater; If the repayment period is nearing the end, the remaining interest may be minimal. The early repayment of cash amounts to a definite return close to the loan rate, but at the expense of reduced liquidity. At a minimum, contingency, medical and possible renovation and maintenance funds are retained for the purpose of determining the amount.
Rates, taxes and fees at the purchasing power boundary
Changes in mortgage rates will affect the availability and total interest for the coming months. When using the calculator, you can raise the interest rate 0.5、1、2 The percentages are operating separately and observe the extent of the family budget. If the loan is re-pricing, note that the change is not imminent; If a fixed period exists, the interest rate after the fixed period ends shall be modelled separately.
The total cost of the house also includes tax on deeds, registration fees, brokerage fees, maintenance funds, renovations, furniture, electrical appliances, property, parking space and maintenance expenses. The cost structure of the new and second-hand rooms is different and cannot be estimated at a fixed rate. Long-term holding also takes into account income growth, inflation and housing mobility, and the fact that the amount of monthly contributions is equal does not mean that the actual burden is the same.
Only the amount of dissensitized and assumed interest rates are entered into the online tool to complete the budget and no contract for the purchase of the house, identification card or bank account information is uploaded. The results of the tool are suitable for comparison and question lists, and contracts must be based on formal bank repayment plans, loan contracts and local policies.
FAQ
The higher the down payment, the better the mortgage will be?
High down payment usually reduces the principal and interest of the loan, but it takes over the liquidity. Contingency payments, renovations, other obligations and cash replacement earnings should be checked simultaneously, and the reduction in interest rates should not be limited.
Why is the monthly calculator not fully consistent with the bank trial bill?
The difference may be derived from the evaluation price, actual lending date, first date, interest rate accuracy, rounding, cost or heavy pricing rules. The principal, interest rate and period in the bank trial statement are subject to a line-by-line comparison and ultimately to the contract.
It's been years. Is it worth paying back early?
The balance of principal and future interest is to be seen first, not the interest paid. If the remaining interest is small, cash on hand is used for a higher and reliable purpose, the return on early repayment may be limited; The default money and liquidity also need to be considered.
Is the equivalent principal appropriate for all high-income families?
Not necessarily. High income volatility and uncertain bonuses may still put pressure on the first high monthly supply. The inclusion of declining incomes and large expenditures in stress tests is more secure than looking at current wages.
Can you estimate the renovation loan and the mortgage?
Only where the principal, interest rate, duration and repayment rules of the two are identical and the contract permits a similar consolidation. In practice, it should normally be calculated separately, adding two additional months of supply to the cost.
Three tables to check the tolerance of the house.
The first table shows fixed housing expenses, including monthly provision, property, parking and insurance; The second table shows one-time expenditures, including down payment, taxes, improvements, furniture and relocations; The third listing of risk buffers includes contingency payments, monthly provision during periods of unemployment and possible maintenance costs. The three tables were consolidated to make it clear how much cash remained to be used after the down payment.
The purchaser shall also confirm facts unrelated to the loan, such as delivery of the house, title, mortgage, school district or use. The mortgage calculator does not check whether the contract has been deferred, area differences or standard disputes for refurbishment. The financial assumptions are recorded separately from legal and engineering facts when looking at houses and contracts, so that the risks inherent in the transaction are not overlooked because the monthly budget is very precise.
If the replacement is planned for five years, the remaining principal, transaction tax charges and possible price changes for sale are estimated, in addition to the interest paid over five years. The total interest on long-term loans is suitable for a more complete holding cost, while short-term holding should be more focused on cash flows and exit costs in previous years. The expected duration of the holding is written into the scenario name and will be clearer when the future resets are repeated.
Concluding remarks: Loans to the full family budget
The mortgage calculator is not a house selection button, but rather a tool for comparison of down payment, loans, interest rates, duration and early repayment. First, the principal calibre is confirmed, then the two repayments are calculated separately, and the liquidity check is made by adding the interest rate increases, the decline in income and the purchase of accommodation. The monthly figures thus obtained would truly serve the decision-making process for buying a house, rather than being carried away by a single number in the advertisement.
