Calculation formulas
Remaining payments = contract payments after the as-of date and on or before the contract end.
Remaining recurring cost = remaining payments × recurring payment amount.
Contract progress = elapsed contract calendar days ÷ total contract calendar days.
This fixed recurring-payment estimate does not model cancellation penalties, prorating, deposits, refunds, taxes, price changes, interest, late fees, or provider-specific rules. Confirm binding dates and amounts in the contract document.
What this contract calculator tells you
Find a fixed-term contract’s end date, calendar progress, complete recurring-payment schedule, payments already scheduled through an as-of date, payments remaining, and estimated recurring costs. It is a schedule estimate rather than an interpretation of contract terms.
How the contract end date is calculated
In term mode, the calculator adds the selected number of calendar months to the start date to find the exclusive anniversary, then subtracts one calendar day. A 12-month contract beginning August 1, 2026 therefore ends July 31, 2027. Calendar months are not treated as 365 divided into equal parts.
How recurring payments are generated
Weekly schedules advance by 7, 14, or 28 UTC calendar days. Monthly, quarterly, six-monthly, and yearly schedules retain the confirmed payment anchor’s intended day. Only occurrences from the contract start through the contract end, inclusive, belong to the contract.
How payments are classified as elapsed or remaining
A scheduled payment on or before the as-of date is classified as scheduled through that date. A payment is remaining only when it is later than the as-of date and no later than the contract end. Consequently, a payment exactly on the as-of date is not counted as remaining.
How shorter months and leap years are handled
A January 31 anchor uses February’s final day, returns to March 31, uses April 30, and returns to May 31. A February 29 yearly anchor uses February 28 in non-leap years and returns to February 29 in later leap years.
Contract progress and calendar time
Primary progress uses inclusive calendar days, not payment count. Upcoming contracts show 0%, active contracts show elapsed inclusive contract days divided by total inclusive contract days, and ended contracts show 100%. Payment progress is displayed separately.
Worked examples
12-month contract with monthly payments
A contract starting August 1, 2026 with a 12-month term ends July 31, 2027. Monthly $50 payments anchored to August 5 produce 12 payments through July 5, 2027. As of October 10, three payments totaling $150 are scheduled through the as-of date; nine remain, costing $450. Total scheduled recurring cost is $600, and the next payment is November 5.
Upcoming and ended contracts
Using the same contract, an as-of date of July 20, 2026 produces UPCOMING status, 0% progress, and all 12 payments remaining. An as-of date of August 10, 2027 produces ENDED status, 100% progress, zero remaining payments, and preserves July 5, 2027 as the final scheduled payment.
Month-end recurrence
For a January 1 through April 30, 2024 contract with monthly payments anchored to January 31, the dates are January 31, February 29, March 31, and April 30.
Leap-day yearly recurrence
A yearly February 29 anchor across 2024 through 2028 produces February 29, 2024; February 28 in 2025, 2026, and 2027; and February 29, 2028.
Frequently asked questions
How do I calculate when a 12-month contract ends?
Add 12 calendar months to the start date, then subtract one calendar day under this calculator’s convention.
Why does a 12-month contract starting August 1 end July 31?
August 1 of the following year is the exclusive anniversary. The inclusive contract period ends one day earlier.
How are monthly payments counted?
The known payment date anchors the recurrence. Only generated dates inside the inclusive contract range count.
Is a payment on the as-of date considered remaining?
No. It is classified as scheduled through the as-of date.
What happens if my payment date is the 31st?
Short months use their final day, while later months return to day 31 when it exists.
Can the known payment date be before the contract starts?
Yes. It establishes the regular schedule; only occurrences inside the contract count.
What happens after the contract has ended?
Status becomes ENDED, progress is 100%, and no contract payments or recurring costs remain.
Can I enter a known end date instead of a term?
Yes. Select the known-end-date method and enter any valid end date on or after the start.
Does this include cancellation penalties?
No. Early termination, cancellation penalties, and provider-specific rules are not modeled.
Does it include prorated final payments?
No. Every generated occurrence uses the same recurring amount. Real first or final payments may be prorated.
Does it include deposits, taxes, or price increases?
No. Deposits, refunds, taxes, price changes, interest, and late fees are excluded.
Can I use it for phone, internet, gym, lease, service, or installment contracts?
It can provide a fixed recurring-payment planning estimate, but actual billing and termination provisions vary.
Is this financial or legal advice?
No. Confirm legally binding dates, payment amounts, prorating, and termination rules in the contract document or with a qualified professional.
