LifeTally · Money and everyday life
Bring music, cloud storage, the gym and other recurring payments into one calculation. Compare weekly, monthly and annual plans, cost per use and a cancellation scenario.
Use one currency for every payment. Changing currency changes the label, not the amounts or exchange rate.
01 · Your recurring payments
An educational example is filled in, not current service prices. Replace it with your own payments.
Cost of the selected scenario ↓Compare up to 12 payments. Values are used only for calculation in this tab: the calculator does not submit them or retain them after reloading.
03 · Which subscription costs more
Totals are rounded to two decimal places in the selected currency. A positive amount below 0.01 is shown as “< 0.01”, not as free. Formula inputs show more precision; calculations use unrounded values, so adding rounded rows can differ slightly from the total.
$10 × 12 ≈ $120.00
$10 ÷ 20 ≈ $0.50
$120 × 1 ≈ $120.00
$10 ÷ 30 ≈ $0.33
$40 × 12 ≈ $480.00
$40 ÷ 4 ≈ $10.00
04 · Where the numbers come from
First convert each payment to an annual equivalent: weekly price × 365 ÷ 7, monthly × 12, annual unchanged. Monthly equivalent = annual ÷ 12; daily = annual ÷ 365. Period total = sum of kept annual costs × years. Cost per use = monthly equivalent ÷ uses per month.
ⓘ This is a constant-price model, not a billing calendar. A weekly plan can have 52 or 53 charges in a particular year. Annual plans are paid upfront even when a monthly equivalent is displayed. Past payments, refunds, trials, price rises, fees and exchange rates are excluded. Savings assume all future payments stop throughout the chosen period.
