Define what you include
Separate setup purchases, recurring monthly care, annual costs and a chosen monthly reserve. Use local quotes and note missing categories. Avoid counting the same bill in monthly and annual inputs. A reserve is your assumption, without a promise of emergency coverage.
Understand the calculation
Monthly equivalent = monthly care + annual costs/12 + monthly reserve. Period total = setup purchases + monthly equivalent × 12 × chosen years. Amounts are assumed constant: the calculation does not add inflation, interest or changes in circumstances.
Keep units consistent
Choose 1–20 years and enter nonnegative amounts in one currency. Changing currency relabels the amounts without converting them. A blank is missing information; zero is a recorded zero. Entries reset on leaving or reloading and are not sent to analytics.
Common questions
Are these current market prices?
No. Enter your own quotes; the example is hypothetical.
Does it convert currencies?
No. Enter amounts already expressed in the selected currency.
A calculation example — not a market quote
- Hypothetical USD inputs
- Setup 100; monthly care 50; annual care 120; monthly reserve 10.
- Monthly equivalent
- 50 + 120/12 + 10 = 70.
- Two-year total
- 100 + 70 × 12 × 2 = USD 1,780; only those categories, with constant amounts.
Your ownership budget planner
Enter quotes in one currency. Blank fields are missing estimates, not zero costs. Totals include only your entries.
Entries remain in this page and are not saved or sent. This is arithmetic for your own estimates, not a quote or coverage guarantee.
